Science Summary:
The Greenland ice sheet (GrIS) contains enough ice to raise sea levels by 7 meters if it were to disappear entirely. Although total loss of the ice sheet is not a concern for the foreseeable future, accurately measuring the total mass balance — accumulation minus loss —of the GrIS remains a critical scientific objective for determining the ice sheet’s present day contributions to sea level rise. Greenland's mass was in near balance in the mid-1990s, but has experienced an increasingly negative mass balance since then with a current annual mass loss of approximately 0.46 - 0.75mm of sea-level equivalent (SLE) per year. The year 2012 proved an "extreme" melt year in Greenland with a single-year loss of 1.59 mm SLE, owing in part to surface mass balance (loss from surface melting) that was three standard deviations below the long-term mean. Light Detection and Ranging (LiDAR) altimetry is one of the primary approaches used to compute mass changes on the GrIS, in part because of its high spatial resolution and sampling capabilities when compared to other approaches such as gravimetry and radar altimetry. The Ice, Cloud and Land Elevation Satellite (ICESat) was used to successfully estimate mass balance for Greenland during much of the last decade. ICESat's successor ICESat-2 is scheduled to launch in 2017 and will continue ICESat's legacy of space-based lidar remote sensing of the Greenland and Antarctic ice sheets. In addition, airborne laser altimetry has been used to estimate ice sheet mass balance and outlet glacier changes since 1991. Such an airborne lidar is fundamental to Operation IceBridge (OIB), which is dedicated to filling the elevation change measurement gap between ICESat and ICESat-2. An unavoidable source of uncertainty in altimetry-based mass balance measurements is the conversion from volume change into mass. One of the primary components of this volume change is firn compaction: the rate at which fresh snow is compressed into glacial ice on the surface of a glacier. At elevations below the equilibrium line, snow melts out entirely to glacial ice each summer, and a density of pure ice may be assumed to calculate changes in mass. However, approximately 80% of the GrIS lies within the accumulation zone, where firn compaction must be accurately measured or modeled in order to perform this volume-to-mass conversion effectively. Direct compaction measurements are spatially and temporally extremely sparse on the GrIS and nonexistent in some large regions, so models remain the primary source for compaction adjustments in mass balance measurements. Most firn compaction models were created and parameterized assuming long -term steady state climate conditions, namely that accumulation and mean temperature remain nearly constant over components of ice sheet elevation change long time periods, an assumption that held true for much of Greenland only a few decades ago. Some of the current models include considerations for melt, percolation and refreezing, but maintain many of the same steady-state assumptions in the underlying physical characterizations of snow forming into ice. The models not only tend to disagree with each other when run under identical steady-state conditions, but also exhibit a broad range of future behaviors when forced with the transient variables of a changing climate. Each model was created and validated against varying levels of field data spanning different regions and time periods. Without a consistently measured validation dataset, it is nearly impossible to determine which compaction models are most correct when estimating firn compaction across a vast region. One of the most widely-cited firn compaction models used during ICESat-1 to calculate mass balance in Greenland estimated that the rate of firn compaction changed by as much as ± 2.5-13.5 cm yr-1 across nearly three quarters of Greenland’s accumulation zone in the six years spanning 2002-2007. This estimated change in compaction rate dwarfs the ±0.4 cm yr-1 measurement accuracy in the baseline science requirements currently proposed for NASA’s upcoming ICESat-2 mission. To successfully calculate the current and future mass balance of Greenland, accurate and timely field measurements are needed to more precisely constrain firn compaction rates across the GrIS.

Logistics Summary:
Researchers on this NASA project (“FirnCover”), will measure compaction rates at a range of depths to differentiate between rapid melt-induced densification and steadier grain deformation at depth in Greenland. With visits to Greenland from 2015 to 2017, a field team will gather data from sampling sites, some existing and others to be installed. Accumulation, temperature, firn stratigraphy and density profiles will be measured at each station to initialize and force compaction models under Greenland’s changing climate. In 2015 a field team of up to six will obtain and build all components of the FirnCover instruments and transmission towers. After flying to Kangerlussuaq via ANG and spending several days preparing for the work ahead, six researchers will fly to Raven Camp, and base there to revisit the existing FirnCover stations (KAN-U, Dye-2, and EKT) by snow machine, maintain the towers and instruments, and install new surface instruments atop the latest layer of snow accumulation to extend the continuous depth-profile compaction measurements. New stations will be installed near the GC-Net weather station at Saddle and NASA-SE. When this work is finished, two team members will return to Kangerlussuaq via chartered Twin Otter and depart Greenland via commercial air. The remaining party will fly via Twin Otter to the rest of the stations (Crawford Point, Summit, and NEGIS) to drill cores and install new stations. They will work at Summit Station, and after the Twin Otter support is finished, return to Kangerlussuaq via ANG in early-mid June. The researchers will depart Greenland, chiefly via ANG, several days later. In 2016, 11 researchers will return to maintain the instruments, continue measurements from the surface, repair equipment as necessary, and collect firn core samples. The team will assemble in Kangerlussuaq via a combination of Air National Guard and commercial flights in April. They will spend about a month tent-camping while visiting existing sites based from hubs at Raven Camp and Summit Station. Air transport between hubs and field sites will be accomplished largely by chartered Twin Otter. The work will end at Summit Station in mid-May, at which point the researchers will return to Kangerlussuaq via Twin Otter, carrying firn core samples if space allows. Researchers will spend several days in Kangerlussuaq processing the firn samples before departing via a combination of ANG and commercial air. In 2017, researchers will remove the stations and transport them back to the home institution.

Via an interagency funds transfer NASA>NSF, CPS will provide Air National Guard coordination for passengers and cargo, including dedicated flights to Raven, KISS user days, in-transit Summit user days, fixed-wing support, truck rental, snow machines/sleds & camp equipment, fuel, communications equipment, and safety gear. The PI will arrange and pay for all other support directly.

Science Summary:
The project plans to install a magnetometer at Summit Station to investigate geomagnetic variations in Central Greenland in support of two projects with complementary scientific aims: (1) Project IceBase is a high altitude geomagnetic survey to be proposed by a consortium around Goddard Space Flight Center to NASA to investigate the geothermal heat flux below the Greenland ice cap. The project aims at producing a Greenland-wide map of magnetic crust depth (Curie-depth), indicative for geothermal heat flux. The derived heat flux map is a boundary condition for ice sheet models to improve, among other things, estimates for global sea level rise due to melting of the Greenland ice sheet. Ground magnetometers are critical when correcting the survey data for natural geomagnetic time variations. Data from Summit Station, due to its location in Central Greenland, in combination with the below mentioned array, is crucial here. (2) The Greenland Magnetometer Array operated by DTU Space is a permanent array of some 15 magnetometer stations located on the Greenland East and West Coasts. The array is ideal for investigating the polar ionospheric current systems and processes related to the coupling of energy and momentum from the solar wind to the magnetosphere and ionosphere. Data is interpreted in combination with satellite data (e.g. NASA's Themis mission, ESA's Cluster mission), or with conjugate stations from Antarctica. The proposed Summit magnetometer experiment will, apart from improved geographical coverage, provide data from the electrically insulating ice cap. This data will be less affected by induced electric currents in surrounding oceans and underlying bedrock than the coastal stations, thus improving the scientific value of the array data as a whole.

Logistics Summary:
Participants in this Danish Technical University (DTU)-funded project will install and collect data from a magnetometer at Summit Station to investigate geomagnetic variations in Central Greenland. The funding period for this grant begins in 2014 and ends in 2020. This work will support two complementary scientific objectives: (1) Project IceBase is a high altitude geomagnetic survey to be proposed by a consortium around Goddard Space Flight Center to NASA to investigate the geothermal heat flux below the Greenland ice cap.

From 2014 to 2020, project personnel may visit Summit Station to maintain or upgrade the magnetometer installation. CPS science technicians will monitor and maintain the magnetometer, electronics, and datalogger year-round. In 2014, two people will visit Summit in June on project business. The science group will not deployment to Summit during 2015 and 2016. The experiment will continue to be maintained by onsite technicians. In 2015 the Lead PI switched from Dr. Jurgen Matzka to Dr. Rico Behlke at which time the grant name was changed from MatzkaDTU to MagnetometerDTU in this database.

CPS will provide Air National Guard support for cargo and passengers between Kangerlussuaq and Summit Station, Summit user days, fuel from Summit stocks, and science tech/labor support for the project. NSF will recoup costs associated with this support directly from DTU. All other items, including KISS user days, will be arranged and paid for by the PI.

Science Summary:
In 2010, the observatory at Summit, Greenland, in the center of the Greenland Ice Sheet (GIS), was expanded to include a comprehensive suite of cloud-atmosphere observing instruments including microwave and infrared spectrometers, cloud radar, depolarization lidar, ceilometer, precipitation sensor, sodar, and a twice-daily radiosonde program. This observing effort was termed ICECAPS (Integrated Characterization of Energy, Clouds, Atmospheric state, and Precipitation at Summit). Continuation of the work was approved / funded late summer 2013 to allow for continuous operation, with moderate enhancements to include new precipitation measurements. Measurements from this expanded instrument suite will be used to derive critical baseline atmospheric data products including: Atmospheric State - tropospheric temperature, moisture, and wind profiles, Cloud Macrophysics - occurrence, vertical boundaries, temperature, Cloud Microphysics - phase, water content, and characteristic particle size, and Precipitation - type and rate. Together these products, when combined with similar ongoing measurements at Summit, can be used to study processes that impact the surface energy budget and precipitation at the site, as well as addressing questions related to atmospheric stability, cloud phase composition, and the persistence of stratiform clouds. It is further anticipated that these observations will continue to be used by a broad cross-section of the scientific community to promote understanding of GIS and Arctic climate, validate satellite observations, and evaluate model simulations. Graduate students play significant roles in most aspects of this project, gaining valuable experience with polar field work, operating instruments, and processing data. In addition, this research team has developed a unique education and outreach plan to work with students from local schools using simple, proxy instrumentation to help develop their understanding of atmospheric principles and observations, and to enhance the scientific curriculum in their schools via a wide range of outreach activities.

Logistics Summary:
Researchers on this collaboration between Walden (1414314, WSU), Turner (1304692, U of OK), Shupe (1303879, CU) and Bennartz (1304544, U of WI) will continue work begun under NSF grant 0856773 "ICECAPS". Researchers will continue an intensive cloud experiment at Summit with fieldwork from late spring 2014 through late spring 2018. Logistic details under 1414314.

Science Summary:
Biospherical Instruments Inc (BSI) has operated NSF’s Ultraviolet Spectral Irradiance Monitoring Network (UVSIMN) between 1988 and 2008. The network included three locations in Antarctica, two in the Arctic (Barrow, Alaska, and Summit, Greenland) and two mid-latitude sites. In 2009, the instruments at Barrow and Summit have been integrated into NSF’s Arctic Observing Network as part of the AON projects “Ultraviolet Radiation in the Arctic” and, since 2012, “Ultraviolet Radiation in the Arctic: 2012-2015.” The award is jointly overseen by Prof. John E. Frederick of the University of Chicago and Dr. Germar Bernhard of BSI and will end on 31-August 2015. To date, the network has produced one of the longest Climate Data Records (CDR) of UV radiation in existence. Measurements at Barrow span the 21-year period of 1991-2012. Measurements at Summit started in 2004 and are ideally suited to probe the free troposphere and study the effects of long-range transport of pollutants and aerosols on UV radiation. Data can also be used for validation of satellite observations, verification of models describing the transfer of radiation through the atmosphere, advancement of climate models, and addressing the SEARCH question such as whether the Arctic is moving to a new state. Data have been used by hundreds of researchers investigating the effects of stratospheric ozone depletion and other climatic factors on UV radiation at the Earth’s surface and subsequent consequences on aquatic and terrestrial ecosystems, and humans.

Logistics Summary:
This grant supports continued UV-visible solar irradiance observing experiments. BSI will operate several radiometers at Barrow, Alaska, and Summit, Greenland. This project is a continuation of the NSF's Ultraviolet Spectral Irradiance monitoring Network (UVSIMN) and NSF grants 0907819 and 0856268. For information regarding the project's prior logistics, see records for 0907819 (2009 only), 0856268, and UVSIMN. At Summit, the instrument is primarily maintained by on-site science technicians, with occasional visits by the research team for maintenance, or tear down/set-up when the structure where the experiment is housed must be relocated. During 2013 the team will make two deployments. In June the team will visit Summit to dismantle the instrument for storage while the Green House structure is relocated. The PI will return to Summit in July to reinstall the instrument in the Green House at the new location. At Barrow, on-site technicians in the employ of Arctic Administrators LLC maintain the instruments.

At Summit Station, CPS will provide access to the Summit infrastructure, accommodations and meals in Kangerlussuaq, user days at Summit, and science technician services. The PI will not send a research team to Barrow using local CPS support in 2013 and 2014, though a visit may be arranged using grant funds. All other logistics will be coordinated by the researchers through the grant.

Science Summary:
This grant will investigate the potential of carbon-14 in ice cores as an absolute dating tool, as a tracer of the past cosmic ray flux and as a recorder of the past fossil fraction of the global methane budget. Cosmic ray particles produce carbon-14 from oxygen-16 directly within near-surface glacial ice and firn. This in-situ produced carbon-14 quickly reacts to form 14C-containing carbon dioxide, carbon monoxide, and methane in the ice matrix. Some or all of the resulting 14C-bearing gases may be lost from the firn to the atmosphere. This research will provide a thorough characterization of in-situ cosmogenic 14C in glacial firn and shallow ice in the Summit region of Greenland. It will examine the retention of cosmogenic 14C in ice grains at all depth levels in the firn column, the partitioning of 14C between carbon dioxide, carbon monoxide, and methane, as well as the production rates and accumulation of cosmogenic 14C in shallow ice below firn close-off. A thorough understanding of cosmogenic C-14 in firn and shallow ice will likely enable the use of C-14 in ice for one or more of the following applications:
 1) If a relatively large amount of cosmogenic 14C is present in ice below the depth at which air bubbles become sealed off, it will be useful as a tracer for past cosmic ray flux. The investigators believe that this is the likely case for 14C-carbon monoxide. 2) If the amount of retained in-situ-produced 14C-carbon dioxide is relatively small compared to 14C-carbon dioxide from trapped air, the study will demonstrate the validity of using 14C-carbon dioxide for absolute dating of ice cores; this has long been a target of ice core studies. 3) If the amount of retained in-situ-produced 14C-methane is relatively small compared to 14C-methane from trapped air, the study will demonstrate the validity of using 14C-methane in glacial ice for determinations of the fossil fraction of the past methane budget, including releases from methane clathrates. This project will establish a new international collaboration between University of Rochester (UR) and University of Bern and result in novel laboratory and field analytical systems. The data from the study will be made available to the scientific community and the broad public through the ACADIS data service. One graduate student will be trained at UR, and one postdoc and one graduate student will be partially supported at Oregon State University.

Science Summary:
The Science Coordination Office (SCO) serves the scientific community, NSF/Division of Polar Sciences (PLR), and the arctic logistics contractor by coordinating input and providing an organized advisory mechanism for PLR regarding decisions impacting Summit Station. SCO makes recommendations to CPS about ways to accommodate or mitigate conflicting requests from different science teams, and suggests ways investigators might accomplish science objectives with smaller logistical impacts. SCO advocates on behalf of the community, suggesting science-based priorities for capital investments by PLR at Summit that will maintain and enhance the value of the site for research while striving to keep the station financially sustainable. This renewal grant includes two new SCO members to represent the broader research community and diversify generations of researchers. It also adds functionality to the existing SCO by increasing SCO guidance and oversight to include research projects on the Greenland Inland Traverse and future research sites on the Greenland Ice Sheet that may host investigations similar to work done at Summit Station. This award supports activities that expand communication: significant updates to the current GEOSummit webpage (e.g. a virtual tour, Summit bibliography, and Summit GIS); a new Summit Listserv and town-hall-style meetings at the Fall AGU meeting; increased efforts at informal direct contact; and semi-annual teleconferences involving the scientific community. The SCO role in long-range and annual planning is to focus on the economic and environmental sustainability of the station in parallel with the preservation of core station scientific activities. These objectives are captured in a developing Long-range Plan for Summit Station.

Logistics Summary:
This collaboration—Dibb (UNH, 1042410, LEAD), Burkhart (UC Merced, 1042531), and Hawley (Dartmouth, 1042358)—will continue support for the Summit Science Coordination Office (SCO) begun under NSF grant 0455623. The SCO was established to coordinate measurements between investigators and the sharing of facilities and personnel on-site; to provide scientific requirements to NSF, its support contractor and European partners as the facility is developed; and to stimulate sharing of data among science projects.

Science Summary:
Researchers at NOAA’s Earth System Research Lab (ESRL) Global Monitoring Division (GMD) conduct a suite of continuous and campaign measurements at Summit Station, including surface and upper atmospheric ozone measurements, air sampling of carbon cycle gases, and elemental carbon measurements. Continuous measurements include: 1. Halocarbon Gases / HATS Flasks (Steve Montzka), a twice-monthly air sampling effort to measure trace gases that are important components of global halocarbon chemistry. These measurements have been ongoing since 2004. 2. Surface ozone measurements (Samuel Oltmans), continual tropospheric air sampling efforts for ozone levels. These measurements were taken from 2000 to 2002, and from 2003 on. 3. Aethelometer / Black Carbon (Andrew Clarke), continual measurements of aerosol elemental carbon (e.g., black carbon) levels. These measurements have been ongoing since 2003. 4. Greenhouse gases / MAKS Flasks (Tom Conway), a weekly air sampling experiement to analyze levels of trace gases that are part of the global carbon cycle. These measurements were taken during winter of 1997-1998, 2000-2001, 2001-2002, and have been onoing since the 2003-2004 winter period. 5. Balloon-borne ozonesondes (David Hofmann) to measure springtime depletion of ozone in the stratosphere. These measurements were first conducted during the late-winter of 2005. All-winter campaigns are expected for subsequent years. 6. Gas chromatograph (James W. Elkins). The Halocarbons and other Atmospheric Trace Species Group of the Global Monitoring Division plan to install a two-channel gas chromatograph that measures atmospheric nitrous oxide, sulfur hexafluoride, CFC-12, CFC-11, CFC-113, chloroform, methyl chloroform, and carbon tetrachloride once every hour at Summit Station. All are greenhouse gases and all but sulfur hexafluoride cause stratospheric ozone depletion.This instrument will be added in 2007. 7. The Camera Lidar (CLidar) (John Barnes) profiles aerosols in the nighttime boundary-layer. The altitude resolution of the aerosol profiles is sub-meter near the ground, which decreases in the upper atmosphere. The technique accurately measures aerosols starting a few meters above the ground where they can be compared with surface measurements and uses a cooled scientific CCD camera with a fisheye lens to image a vertical laser beam that is a few hundred meters away. Normally an additional laser would be needed, but at Summit the laser from the present ICECAPS Lidar is used. The entire 100 degree image is acquired simultaneously (no moving parts) and then analyzed to get the aerosol profile.The CLidar acquires an aerosol-scattered-light profile about every five minutes. It is very sensitive to thin layers of ice and other particulates which help in interpreting some of the other measurements currently made at Summit.

Logistics Summary:
For this NOAA program, on-site science technicians maintain a suite of year-round measurements on behalf of NOAA researchers. These measurements began in the mid 1990s and are ongoing (part of GEOSummit since 2003). NOAA representatives visit Summit Station annually to install / maintain instruments, train science technicians, and conduct measurements. Starting in 2005, NOAA began staffing science technician rotations as Summit Station during the winter phases. Beginning in 2008 NOAA increased staffing to be year-round. Monitoring projects on site include: carbon cycle gas sampling flasks, black carbon measurement, halocarbons and trace species flask sampling, meteorology suite, stratospheric ozonesondes, aerosol measurements, surface ozone measurements, and an in-situ gas chromatograph for greenhouse gas measurements. NOAA will continue to collaborate with Georgia Tech on activities related to the aerosol instrument suite that was previously installed and maintained by the Bergin project (NSF grant #1023227). NOAA program highlights at Summit Station over the last few years include: - During summer 2007 a four channel gas chromatograph was added to the suite of NOAA instruments. - During summer 2008, in addition to ongoing work, researchers extended the ozonesonde experiment by launching about 20 additional balloons in April and again in July for an intensive field campaign. - In February 2009, a NOAA staff member flew to Summit Station via the Twin Otter on a crew turnover flight to repair an instrument, departing the station on the return flight approximately one week later. - During August 2009, the NOAA field coordinator attended an on-site planning meeting. - In 2010, in addition to ongoing measurements, CPS staff relocated the Temporary Atmospheric Watch Observatory (TAWO) and instrument tower (where the NOAA instruments are mounted) to approximately 1 km south of Summit Station. - During 2011 and 2012 the NOAA field coordinator made a routine visit to Summit Station for instrument maintenance. - During 2013 the TAWO building was lifted and the TAWO tower was extended. The on-site science technicians coordinated with the Boulder-based NOAA team to support the instrumentation during the transition. - Also during 2013, the NOAA ESRL GMD deputy director traveled to Summit Station in late June for a site visit. During 2014, one NOAA researcher will travel to Summit in June for maintenance and upgrade activities. NOAA will continue to hire and deploy science technicians for all the three staffing phases. During 2015, three researchers will travel to Summit in June, July, and August for maintenance and upgrade activities. These include upgrading the meteorological sensor suite, assisting with the science impacts from the TAWO facility raise project, and performing a quality control visit to evaluate the setup of the aerosol measuring suite of instrumentation. In 2016, NOAA researchers will travel to Summit to relocate the meteorological suite of instruments from the TAWO tower to the 50m tower, install broadband solar radiometers to inter-compare with existing solar measurements from Summit station, reinstall instrument inlets on the TAWO inlet mast, and potentially reconfigure the TAWO interior layout of instruments to optimize the available footprint. Additionally, NOAA is planning to modify the CATS GC to eliminate methane containing P5 carrier gas to directly address concerns about elevated methane levels within the facility. Researchers will return in 2017, details are TBD.

CPS will coordinate personnel and cargo transport to and from Summit; and provide access to Summit Station infrastructure, Summit user days, Kangerlussuaq user days, purchase of ozone sondes, construction support, and science technician support with tasking shared between the NOAA and CPS year-round technicians. The PI will arrange and pay for all other logistics through the grant.

Science Summary:
With this experiment, the Academia Sinica, Institute of Astronomy and Astrophysics (ASIAA) will use a radiometer to survey sky clarity and atmospheric stability over Summit Station, Greenland, at submillimeter wavelengths. This activity is a piloting program for the possible establishment of a new station for the Very-Long-Baseline-Interferometry (VLBI) network at submilimeter wavelengths. Recent rapid progress on VLBI technique has now achieved the required spatial resolution to image the nearby Black Hole shadows, or the event horizons of the Black Hole. Proper distribution of antennas is essential to get a good quality of images, and the researchers are testing several potential site candidates at which to set a new antenna. Submillimeter observations require a very dry atmospheric condition. A cold, high altitude site, such as the Summit Station, is a good candidate for this purpose, and the final decision on site selection can only be made through extensive atmospheric monitoring of transmission parameters associated with submillimeter waves.

Logistics Summary:
The objective of the ASIAA radiometer experiment is to survey the sky clarity and the atmospheric stability from Summit Station at submillimeter wavelengths. This activity is part of a piloting program for the possible establishment of a new station for the Very-Long-Baseline-Interferometry (VLBI) network. Summit Station was selected as a potential candidate for the VLBI network because of the very dry atmospheric conditions, cold, and high altitude characteristics of the site. The radiometer was initially installed at Summit Station summer 2011 and will continue operating through winter 2014/2015. During 2011 a field team of two researchers will deploy to Summit to install the instrument. The radiometer will run autonomously for the duration of the experiment. Looking towards potential installation of an antenna near Summit Station, in 2012, the researchers will investigate options for project logistical support at the Thule Air Base. A team of three researchers will travel to Thule in early April for an eight -day site visit. They will travel to Thule via the ANG logistics chain, and then depart through Kangerlussuaq, on commercial air. Two researchers will return to Greenland in June and visit Summit Station for familiarization and planning; activities include a day trip to the future site of the Isi station. A third team member will visit Summit in August to conduct radiometer maintenance. In 2013, the instrument will continue to run with no team member travel to Greenland for this project. During 2014, a research participant will visit Summit Station for instrument maintenance and upgrades. The instrument will run autonomously through winter 2014/2015 with minimal support from the on-site science technicians. During 2015, one team member will visit Summit Station in April - May to address problems that arose with the instrument during the winter of 2014/2015.

CPS will provide Air National Guard (ANG) coordination for passengers and cargo between Kangerlussuaq and Summit Station; liquid nitrogen shared with ICECAPS for August calibration; Summit user days, power and infrastructure at Summit Station, with science technical support if on-site assistance is required. The PI will pay for these costs via an NSF-billable arrangement. For all other support, the PI will arrange and pay expenses directly.

The SCO was established to coordinate measurements between investigators; to optimize the sharing of facilities and personnel on-site; to provide scientific requirements to NSF, its support contractor and European partners as the facility is developed; and to stimulate sharing of data among science projects. From 2011 to 2016, SCO members will make regular trips to Summit, often combined with already-planned fieldwork in support of other grants. CPS will work closely with the SCO to develop and implement plans for Summit and the Greenland Traverse (GrIT) that meet the evolving needs of the science community. Activities in 2015 will include a continued survey of ice sheet movement in the near Summit area with a goal of determining the spatial pattern of horizontal strain that would act on multi-kilometer length of cable. This was a NSF requested study, now referred to as the Summit Strain Net study, in 2014 to better understand the implications of a number of factors in the long range plan for Summit Station. Those survey points which can be checked via foot will be; those that can’t will be accessed via snow machine. Additionally the Science Coordination Office plans to send one member for a site visit during the last flight period of the 2015 summer. In August 2016, one SCO member and one research assistant will travel to Greenland for an annual site visit, which will be made in collaboration with the Philip Lubin field team. In addition, the StrainNet survey will be completed during the same visit to avoid a separate deployment..

CPS will provide travel to/from and access to infrastructure and services at Summit Station. The PIs will arrange and pay for all other expenses through the grant.

Science Summary:
This study contributes to the Arctic Observing Network (AON). The PI will collect four years of continuous measurements of atmospheric methane, and non-methane hydrocarbons (NMHC: ethane, ethyne, propane, iso-butane, n-butane, iso-pentane, n-pentane, benzene, toluene) at the Greenland Environmental Observatory at Summit (GEOSummit). An existing monitoring system that has previously been operated at Summit for two seasons will be deployed. This gas chromatography instrument is specifically tailored towards operation at this remote arctic site, as it is fully automated and remotely controllable. A second analytical channel will be added to include monitoring of the important climate gas methane with the same instrument. This project will deliver four years of continuous atmospheric concentration data of methane, with approximately two-hour time resolution, and nine C2-C7 NMHC at low parts per trillion sensitivity (for NMHC) at Summit. These data will expand upon the previous 2008-2010 NMHC measurements from Summit, and will provide an overall eight year record for these gases (with a two year gap). These measurements will complement the NMHC monitoring within the NOAA-INSTAAR global flask sampling program, which has provided bi-weekly NMHC data for five arctic sites for the past seven years. The much higher resolution in-situ data from this study will add value to the interpretation of the NMHC flask records. By applying chemical transport modeling, the in-situ data will allow researchers to decipher air pollution transport into the Arctic and contributions from different emission source region contributions at lower latitudes. The methane and NMHC monitoring will make a pivotal contribution to the World Meteorological Organization (WMO) Global Atmospheric Watch (GAW) Volatile Organic Compound (VOC) program, as it will provide the only high time resolution in-situ NMHC site in the Arctic.

This study contributes to the Arctic Observing Network (AON) and entails continuous monitoring of atmospheric methane and non-methane (C2-C7) hydrocarbons at Summit Station, Greenland. An existing monitoring system that was operated at Summit Station for two seasons from 2008 through 2010 and then moved to Toolik Field Station (both under NSF grant #0713943), returned to Greenland in the spring of 2012. The instrumentation operates year-round, with remote monitoring by the PI and in-situ attendance by CPS science technical staff. During 2012, a team of two researchers spent a week at the station in April to install the monitoring system, and one researcher returned to Summit for maintenance activities prior to station close-out in August 2012. Similarly, for the 2013 field season the research team made two trips to Summit Station, April and August During 2014, one researcher traveled to Summit Station in February with the CPS staff turnover crew to support critical instrument maintenance (routing commercially through Iceland and utilizing the already scheduled Twin Otter charter flights to / from Summit Station). During the main summer research season, participants from the research team will travel to Summit in mid-May, and again in mid-August, for additional instrument maintenance activities. Travel to / from Summit will be via the Air National Guard logistics chain through Scotia, NY, and Kangerlussuaq, Greenland. During 2015 and 2016, one researcher will again travel to Summit Station in April/May to perform instrument maintenance activities. A subsequent trip in August will accomplish the same purpose. The instrumentation will run continuously into 2017 (via an NSF no-cost extension, originally planned to be removed in August 2016). A trip is planned for April and August.

CPS will provide ANG support for passengers and cargo, compressed hydrogen and cylinder rental, user days at the KISS facility in Kangerlussuaq, user days and access to Summit Station infrastructure, rack space in TAWO, use of the existing TAWO tower, and science technical support. The PI will arrange and pay for all other costs through the grant.

NSF_Award_Info: http://www.nsf.gov/awardsearch/showAward.do?AwardN...
Data: https://arcticdata.io/

Science Summary:
Pollution is often transported to the Arctic from nearby continents. Polluted air from human activities and forest fires can contain relatively high levels of nitrogen oxides. In the Arctic, these nitrogen oxides can foster the production of ozone, a significant greenhouse gas. The arctic climate is particularly sensitive to the effects of greenhouse gases, so monitoring these pollutants in the Arctic is important. This grant funds long-term measurements of nitrogen oxides (NO and NO2) at GEOSummit, Greenland, using state-of-the-art technology. The dataset garnered from this work will expand upon measurements of nitrogen oxides performed at the site from 2008-2010, providing a robust dataset spanning nine years. The measurements will provide important information on the concentrations of nitrogen oxides transported to the Arctic, which vary both seasonally and annually, and the resulting impact on arctic ozone levels. The project will contribute to the Arctic Observing Network (AON) and the Study of Environmental Arctic Change (SEARCH). Project data will be made available to researchers for studies to improve understanding of current impacts of transported pollution on greenhouse gas levels and estimates of climate change feedbacks within the Arctic. The data will also be utilized by educators for classroom teaching and they will support the training of new graduate students by providing a unique opportunity to further their research interests and educational growth in the field of atmospheric sciences.

Logistics Summary:
This project expands upon work funded by NSF grant 0713943 (PI Helmig) and a NASA grant called ‘NASAPolarCat,’ for which Kramer was a postdoc / PI. The PI will perform long-term high-frequency measurements of nitrogen oxides (NO and NO2) at Summit Station, Greenland, from late-summer 2012 to 2015. A field team of two or three researchers will travel to Summit Station each year for approximately three weeks each time to calibrate/maintain the instrument. The researchers will travel to and from Summit Station via the Air National Guard. The 2012 objectives involve instrument installation, testing, and trouble-shooting; and training the CPS science technicians on experiment protocols. These objectives will require two researchers to spend approximately four weeks on station beginning in late June. During 2013, the research team will return to Summit Station for maintenance and troubleshooting activities. These objectives will require two researchers to visit Summit Station during different deployments of varying length. During 2014 three researchers will visit Summit Station, with deployments beginning in April, for calibration and maintenance activities. In 2015 the PI accepted a position in the UK. With no co-PIs or alternates, the decision was to demobilize the experiment during April/May 2015. Two science team members will travel to Summit to disassemble and pack up the instrument, equipment and compressed gasses for southbound shipment. These items will be returned from Summit to CONUS during May 2015 (approximately).

CPS will provide ANG support for passengers and cargo, compressed gases and cylinder rental, user days in Kangerlussuaq, user days and access to Summit infrastructure, project workspace in the Temporary Atmospheric Watch Observatory (TAWO), access to the TAWO tower, and science technician support. The PI will arrange and pay for all other logistics through the grant.

Science Summary:
The main goal of this work is to provide the first reliable record of pre-industrial carbon monoxide (CO) concentration and stable isotope composition in the Arctic atmosphere, which will also be representative of a large part of the Northern Hemisphere. Carbon monoxide concentrations are a crucial component of any complete modern or past atmospheric data set because CO plays a key role in global atmospheric chemistry by being the largest single sink of hydroxyl radicals in the lower atmosphere. Carbon monoxide concentration in combination with stable isotopes is also a powerful tracer for large-scale biomass burning variations. Pre-industrial carbon monoxide concentration in the northern hemisphere (where anthropogenic impacts have been by far the strongest) is poorly characterized, with prior measurements made using an older technique in the 1990s on only a few samples from one ice core. No published carbon monoxide isotope measurements from northern hemisphere ice cores are currently available. Researchers on this project will collect a new large diameter ice core near Summit, Greenland using the Blue Ice Drill (BID), providing ice from 80 to 170 meters depth (air age from about 1960 to about 1600 AD). Continuous measurements of carbon monoxide concentration will provide a high-resolution record over the entire ice core and identify ice layers where carbon monoxide is well preserved. High-precision discrete analyses of carbon monoxide concentration and isotopic composition will then target ice from these layers. Continuous analyses of trace chemistry and discrete analyses of trace organics will also be conducted to establish the ice core chronology and improve understanding of mechanisms of in situ carbon monoxide production in ice. Atmospheric histories for carbon monoxide concentration and isotopic composition will be derived using a combination of firn-ice gas transport and inverse models, and the implications for pre-industrial carbon monoxide budget will be investigated with the use of a climate-chemistry model. This approach maximizes the chance of obtaining a reliable history of carbon monoxide concentration and isotopic composition through careful site selection and the application of novel ice drilling and analytical techniques. Results from the study will be made available to the scientific community and the general public through the NSIDC and NOAA Paleoclimatology data centers. The work will contribute to the training of two graduate and 2 undergraduate students, support an early career investigator, and establish several new collaborations among the investigators.

Logistics Summary:
This collaborative project between Petrenko (1406236, Rochester, LEAD), McConnell (1406219, DRI), Mak (1405817, Stonybrook), and Tsigaridis (1404158, Columbia) will continue work begun under the lead PI's existing 14C project (1203779). This new award will be folded into the existing logistics and fieldwork that will be conducted ~10km from Summit Station again in 2015. The main goal of the project is to provide a first reliable atmospheric reconstruction of carbon monoxide (CO) and its isotopes from Greenland ice back to 1600 AD. Logistic details under 1406236.

Science Summary:
This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). This award supports the continuation and expansion of long-term measurements of the Arctic atmosphere, snow, and other Earth system components at the Summit, Greenland, Environmental Observatory (GEOSummit). The original measurement program began in 2003 and contributes to the Arctic Observing Network (AON) and the Study of Environmental Arctic Change (SEARCH). Year-round measurements at least 10 years in duration are required to observe and quantify the roles of large-scale, multiyear oscillations in oceanic and atmospheric circulation (e.g., Arctic Oscillation) as well as long-term changes in industrial emissions and land use. Long-term, broad-spectrum, and high-time-resolution measurements also are required to determine transport pathways and other linkages between low- and mid-latitude industrial emission sources and Arctic climate. Because transport pathways vary strongly with altitude and Summit is the only high elevation observing site in the Arctic and well separated from local emission sources, it is an essential node in AON. Located at an elevation of 3,100 m on the Greenland ice sheet, GEOSummit is part of a network that includes sites at Barrow, Alaska; Alert, Canada; and Mt. Zeppelin, Svalbard. The "Broader Impacts" of these observations are numerous and include the potential to transform understanding of the role of natural and anthropogenic aerosols in climate forcing, to improve climate models and the prediction of future Arctic environmental change, and to enhance the interpretation of ice core records of paleo-environmental variability. The program also will include education and training, with an emphasis on the participation of under-represented groups, through the involvement of undergraduate and graduate students, and a postdoctoral associate.

Logistics Summary:
This grant continues measurements begun under grant #0336450 (Bales). The goal of the project is to continue and expand ongoing long-term measurements of the arctic atmosphere, snow, and other Earth system components at the Summit Greenland Environmental Observatory (GEOSummit). The long-term measurements program at GEOSummit is a close partnership between the Desert Research Institute (DRI), University of California (UC-Merced, UC-Davis), NOAA’s Global Monitoring Division (GMD), and others. The Long Term Observations (LTO) grant funds a suite of year-round measurements from 2009 through 2014, supported by on-site science technicians. In addition to the LTO measurements, Summit Station technical staff will carry out measurements initiated by investigators under other grants, including a significant sampling campaign by NOAA, Baseline Surface Radiation Network, and 50-meter tower experiments at Summit. During campaigns each summer, the research team will conduct field measurements and instrument maintenance. The research deployments will occur seperately for different investigators associated with the project. Additionally, the Steffen deployment to support this project will be conduted in conjunction with the NASAAWS effort. On-site science technicians will take over on year-round measurements when the research team is not on-site. In 2010, PolarTREC teacher, James Pottinger (0956825JP) will join the team for their fieldwork at Summit Station. This project’s field work in June 2011 will involve a team of six—three researchers and again PolarTREC teacher James Pottinger for co-PI Koni Steffen; and a team of two researchers for PI Joe McConnell. The Steffen team will fly to Summit Station in early June via Twin Otter; about a week later, the McConnell team will arrive at Summit via the ANG logistics chain from Kangerlussuaq. In 2013, the ongoing research will be supported with a late-May site visit from a team of four researchers led by co-PI Konrad Steffen. While at Summit the team will service the AWS, the BSRN instruments, and the lower level of the 50-meter tower. The team will arrive and depart Summit Station via Twin Otter as part of the NASAAWS effort. In addition, in July of 2013, one team member will make a trip to Summit to repair an instrument. In 2014, the ongoing research will be supported with a late-May site visit from a team of four researchers led by co-PI Konrad Steffen. While at Summit the team will service the AWS, the BSRN instruments, and the lower level of the 50-meter tower. The team will arrive and depart Summit Station via Twin Otter as part of the NASA AWS effort.

CPS will provide ANG coordination for shipment of cargo and cold samples, user days and access to the Summit Station infrastructure, science technician services (including instrument operation, maintenance, and sample collection), ISC boxes and supplies, Milli-Q filters and other assorted materials, and access to the existing 50-meter tower (either training for grantees or an appropriately trained science technician). The researchers will pay for other costs through the grant.

Science Summary:
The Keweenaw Research Center (KRC) of Michigan Tech University (MTU) has hosted and will continue to host the Society of Automotive Engineers (SAE) Clean Snowmobile Challenge (CSC) event for the next three years at its 500-acre test track near Houghton, Michigan. University teams from across the US and Canada compete for the title of cleanest and quietest snowmobile. This grant encourages university teams to participate in the challenge by reimbursing travel expenses and other participant costs associated with the competitions’ Zero Emissions category. Conventional snowmobiles are suitable as transportation in extreme polar locations; however, due to their higher carbon emissions, they are less suitable where their output would skew the research results. The Zero Emission category of CSC challenges undergraduate students to look for solutions to this problem. In doing so they learn the needs of the polar research program and they also learn about electrification of transportation vehicles, a timely topic as we search for alternatives to the use of fossil fuels for energy. The SAE Clean Snowmobile Challenge provides a venue for students to search for solutions to the needs of the NSF's arctic research effort.At the same time, it provides a conduit for public dissemination of the work of the polar program.

Logistics Summary:
This project continues NSF award 0808798 and supports travel and participation expenses for teams competing in the zero emissions category of the Clean Snowmobile Challenge (CSC) from 2012 - 2014. In addition, each year one team in the zero-emissions category may be invited to demonstrate its vehicle technology and field test its snowmobile at Summit Station. This opportunity gives the students first-hand knowledge of the conditions under which the snowmobile must operate. Each year beginning in 2012, one student team member may be selected to visit Summit Station for about a week. The student will introduce the vehicle to the Summit community and also tour the facilities and the experiments at the station. The snowmobile may remain after the student's departure, operating for the duration of the field season before it is returned to the home institution. The zero emission snowmobile is used at Summit Station to access the satellite camp and other 'clean air' sectors. This allows researchers to quickly, efficiently and safely access their sites without compromising data collection. (No participant traveled to Summit in 2014).

For each team member who is invited to Summit Station, CPS will provide shipping for the snowmachine, participant travel, and user days at Summit and Kangerlussuaq. The PI will arrange and pay for all other logistics through the grant.

Science Summary:
A better understanding of Arctic cloud and aerosol properties, structure and formation is essential to understand the specific response of the Arctic in the context of global climate change. A lack of coherent high vertical and temporal resolution observations of cloud particles, aerosols moisture advection (i.e. water vapor) and thermodynamics, creates large uncertainties in current model estimates of cloud properties and inhibits our understanding of cloud radiative and precipitation impacts on the surface. As a result, current weather and climate models poorly parameterize clouds over the Arctic and more specifically over the Greenland Ice Sheet (GIS). A reduction in this uncertainty is particularly important above the GIS, where clouds act as sinks and sources to the ice mass balance by modulating the surface radiation budget and available precipitable water. To gain the understanding necessary to reduce this uncertainty, a new autonomous multi-wavelength, polarized Raman lidar will be developed and deployed at the NSF's observatory in Summit, Greenland. The new lidar observations will employ multiple wavelengths and polarizations to observe elastic and inelastic scattering from the Arctic atmosphere enabling regular retrieval of temperature, water vapor and extinction profiles. This combination of observational capability will create a coherent dataset of high-resolution thermodynamic, cloud and aerosol observations through the Arctic troposphere and lower stratosphere above Summit. Broadly, this addition to the NSF Observatory at Summit, Greenland as part of the larger Arctic Observing Network fits well within the Study of Environmental Arctic Change (SEARCH) implementation plan. Thus, this instrument will significantly enhance Arctic observing infrastructure and advance observations and understanding of change in the Arctic. This instrumentation and observations are the first of their kind on the GIS and will expand the existing, although modest, network of such measurements across the Arctic. This project will also provide a unique experience and educational opportunity through the combination of fieldwork and subsequent data processing for graduate students at the University of Colorado.

Logistics Summary:
Researchers on this project will continue work on the existing lidar system (installed by Walden/ICECAPs project- NSF grant #1304657). Researchers on this project will also develop a multi-wavelength, polarized Raman lidar. The grant originally funded instrument installation at Summit Station in 2015, with subsequent observations running through 2018 before decommissioning. However, due to changes in the original operating requirements of the lidar and facilities capabilities that do not currently exist at the station, installation has been deferred until such time as infrastructure able to support this experiment can be provided. The researchers will complete development and assembly of the polarized Raman lidar with potential subsequent testing in Colorado, with some field work in 2014 and 2015 with relation to this grant and other projects. During summer 2014 a field team of three will deploy to Summit Station, Greenland for measurements and maintenance activities with the existing lidar system, which was originally installed as part of the Walden / ICECAPS project. Due to Air National Guard flight cancellations, in 2014 only, two researchers will fly commercial air to Kangerlussuaq and the via twin otter to Summit Station. The third researcher will fly via the Air National Guard in August. In 2015, science team members will visit Summit Station four times in support of two related instruments. First, they will reinstall the CAPABL instrument. CAPABL is part of the ICECAPS suite of instrumentation and is also an instrument test-bed for components of the larger Raman lidar. This instrument was removed in August 2014 to address alignment and operational issues; it will resume operation at Summit starting in late April. Researchers will re-install and optimize the CAPABL in the Mobile Science Facility (MSF) during May and June. Also approved is the test operation at Summit of a European Space Agency (ESA)-supported, UK National Center for Atmospheric Science (NCAS)-owned Doppler wind lidar (DWL). The DWL measures radial velocity in clear skies and during light precipitation events. The DWL will be tested at Summit Station between April 25 and June 29. The science team will assume all installation, monitoring and disassembly activities for this installation as they will be on site for the duration of the test phase.

CPS will provide Air National Guard support for personnel and cargo between NY, Kangerlussuaq and Summit Station, Kangerlussuaq and Summit Station user days, science technician support at Summit Station, use of the Mobile Science Facility (MSF) space and utilities. All other logistics will be arranged and paid for by the PI.

Science Summary:
The goals of this project are to characterize the crust and mantle signals associated with the Precambrian to present-day assembly of Greenland, including: identifying the structure and fabric underlying Archean and Paleoproterozoic craton and fold-belt regions; characterizing the nature of the Iceland hotspot's interaction with the Greenland crust and lithosphere; and identifying regions of possible high heat-flux under the ice sheet. The information derived from this study will provide key input for models of glacial isostatic adjustment and models of ice-sheet development and evolution, and will help answer outstanding questions about continent assembly and stability, the history of the Iceland plume, and possible unrecognized modern-day tectonic activity in northeast Greenland. The research will lead to a greatly improved understanding of the crust and mantle structure of Greenland, the way this structure has evolved with time, and its influence on modern-day geophysical processes in the cryosphere and solid Earth. The results of this study will provide important inputs for ice-sheet models and models of glacial isostatic adjustment. The accuracy of both types of models is critical for accurate predictions of sea-level rise. The findings of this study will be relevant for understanding continental assembly and preservation worldwide. The seismological models derived in this project will also allow improved estimates of source parameters for tectonic and glacial earthquakes. Raw data and derived data products will be publicly available through the IRIS and UNAVCO archives. The educational materials produced through this project will be available for general use, and project outreach efforts will support U.S.-Greenland partnership in education. The project will train one graduate student and 2 to 3 undergraduate students.

Logistics Summary:
Scientists working on this geophysical study of the crust and upper mantle of Greenland aim to characterize the seismic velocity structure of Greenland's crust and upper mantle in three dimensions; and to integrate these results with gravity and heat-flow data, laboratory estimates of material properties, and petrological data to map variations in temperature, composition, and heat flux. Researchers will use seismic data from the NSF- and internationally funded GLISN seismic network, supplemented by targeted collection of data at a limited number of temporary PASSCAL stations. Field work begins in the summer of 2014, continues in 2015, and ends in 2016. In 2014 a field team of 3 will deploy seven seismic stations (provided by PASSCAL), six located on the northern ice sheet and one on the East Greenland coast. The power system consists of solar panels and rechargeable batteries in a large Hardigg case attached to the seismic sensor, which sits in a small barrel. The team also will deploy GPS stations at two of the sites with a similar power system and overall setup. The stations will be serviced in summer 2015, and retrieved and returned to the US in summer 2016. The team will travel to Greenland in June 2014 using the ANG logistics chain, and base at Summit Station to deploy the inland sites. At Summit, the field team will test the seismic systems first, building them into fully functional systems before breaking them down and packing them for transport via Twin Otter to the installation sites. The team will make day trips to the installation sites, returning to Summit each day. When this work is complete, the researchers will depart with the Twin Otter and fly to Akureyri. Approximately two weeks later, the field team will return to Kulusuk to install their final site in SE Greenland. The team will fly commercially to Kulusuk and test equipment shipped there earlier in the season. The Norland Air Twin Otter will then pick up the team and cargo in Kulusuk and fly to Kagssortoq where the researchers will install the final station. They will spend one night in the field, and return to Kulusuk. The Twin Otter will return to Akureyri, and the researchers will depart Greenland or continue on education-and-outreach work related to this grant but not requiring logistics support. In 2015 the team will again use the ANG logistics chain and base at Summit to deploy to the northern sites for maintenance visits. A Norland Air Twin Otter will fly from Akureyri, Iceland to Summit to work with the team. They will take day trips to the installation sites, returning to Summit each day, except for one when they will overnight at either Danmarkshavn or EGRIP. When this work is complete, the researchers will depart with the Twin Otter and fly to Akureyri. After one day in town, the field team will fly via Twin Otter to their final site in SE Greenland at Kagssortoq (SE1), where they will swap the data-logger and make some improvements at the site. They will spend one night in the field, and return with the Twin Otter to Akureyri. In 2016, four researchers will return to Greenland, flying via ANG to Kangerlussuaq, and then putting in via LC-130 to a newly established deep drill site north of Summit Station called EGRIP (East GReenland Icecore Project, managed by the Centre of Ice and Climate, University of Copenhagen). The team will base at EGRIP and visit their seismic sites via Twin Otter to dig out, dismantle, and remove all project equipment and batteries for retrograde to EGRIP. Each site will require two flights due to weight. When the work is completed, a total estimate of 7000 lbs. of equipment and batteries will be retrieved by LC-130 and returned to Kangerlussuaq during the late June flight period. Meanwhile, the Nettles team will return to Akureyri via the Twin Otter and stay for two nights. Three team members will then return to Greenland to pull out the Kagssortoq site (SE1) in the southeast, an effort involving one overnight in the village. When this work is done, the researchers will return to Akureyri for onward travel to the US.

CPS will provide Air National Guard (ANG) coordination for passengers and cargo, user days in Kangerlussuaq and EGRIP, freight to/from EGRIP and from Kulusuk to Kangerlussuaq, fixed wing charters, accommodation in Kulusuk, and camp and safety equipment. PASSCAL will provide tools and assistance with field support. UNAVCO will provide GPS units. All other logistics will be organized by the researcher and paid through the grant.

Science Summary:
This grant will investigate the potential of carbon-14 in ice cores as an absolute dating tool, as a tracer of the past cosmic ray flux and as a recorder of the past fossil fraction of the global methane budget. Cosmic ray particles produce carbon-14 from oxygen-16 directly within near-surface glacial ice and firn. This in-situ produced carbon-14 quickly reacts to form 14C-containing carbon dioxide, carbon monoxide, and methane in the ice matrix. Some or all of the resulting 14C-bearing gases may be lost from the firn to the atmosphere. This research will provide a thorough characterization of in-situ cosmogenic 14C in glacial firn and shallow ice in the Summit region of Greenland. It will examine the retention of cosmogenic 14C in ice grains at all depth levels in the firn column, the partitioning of 14C between carbon dioxide, carbon monoxide, and methane, as well as the production rates and accumulation of cosmogenic 14C in shallow ice below firn close-off. This project will establish a new international collaboration between University of Rochester (UR) and University of Bern and result in novel laboratory and field analytical systems. The data from the study will be made available to the scientific community and the broad public through the ACADIS data service. One graduate student will be trained at UR, and one postdoc and one graduate student will be partially supported at Oregon State University. Three UR undergraduates will be involved in fieldwork and research. The work will support an early career scientist. All of the investigators will continue to participate in public outreach.

Logistics Summary:
This collaboration is between Petrenko (1203779, U of Rochester, lead), Severinghaus (1203686, UCSD) and Brook (1204084, OSU) to study the production and retention of cosmogenic carbon-14 in polar firn. During three years of field work beginning in 2013, teams will drill and harvest ice from a camp in the vicinity of Summit Station, Greenland; they also will sample firn air in 2013. In early May 2013, a team of nine, including three drillers, will travel via the ANG logistics chain to Summit Station. From Summit, they will use snowmachines to reach their field camp located 10km NNW. The team will camp at the site for approximately one month where they will drill cores and collect firn air samples. Researchers will return weekly to Summit Station to resupply food and other stores. At the end of the field season, the team will return to Summit Station and depart via the ANG. CPS will arrange for core transport from Summit, with appropriate cold storage at points en route. During 2014 a field team of eight will return to the Summit Station area, and work from a field camp at the same location as 2013. Cores will be collected using the IDDO Blue Ice Drill, and with the exception of six boxes of samples, the cores will be processed on-site using a propane melter. The team will camp at the site for approximately six weeks with weekly trips to Summit Station for use of station resources. At the end of the field season, the team will return to Summit Station and depart via the ANG logistics chain. CPS will arrange for core transport from Summit, with appropriate cold storage at points en route. During 2015, the third and final year of the project, a team of 9 researchers and two drillers will travel via the ANG logistics chain to Summit Station. From Summit, they will use snow machines to return to their field camp located approximately 10km NNW of the station. The team will camp at the site for approximately 6 weeks where they will drill cores and collect firn air samples. Researchers will process the cores on site using a propane melter to extract gas samples. Researchers will return weekly to Summit Station to resupply food and other stores.

For the combined Petrenko led projects (1203779 and 1406236), CPS will provide ANG airlift for the field team and cargo; en route user days at Kangerlussuaq and Summit Station; field camp and safety equipment from the CPS inventory; construction support for camp setup / takedown and various support requirements (i.e. core storage trench, melter platform, and sample trays); provision of generator support and fuel; provision of food; CPS Camp Coordinator support; and shipment for up to 100 ice core boxes of frozen samples Summit > Kangerlussuaq > NY > NICL. IDDO will provide the drill and related drilling support while in the field. All other logistics will be organized by the researchers and paid through the grant.

Science Summary:
The main goal of this work is to provide the first reliable record of pre-industrial carbon monoxide (CO) concentration and stable isotope composition in the Arctic atmosphere, which will also be representative of a large part of the Northern Hemisphere. Carbon monoxide concentrations are a crucial component of any complete modern or past atmospheric data set because CO plays a key role in global atmospheric chemistry by being the largest single sink of hydroxyl radicals in the lower atmosphere. Carbon monoxide concentration in combination with stable isotopes is also a powerful tracer for large-scale biomass burning variations. Pre-industrial carbon monoxide concentration in the northern hemisphere (where anthropogenic impacts have been by far the strongest) is poorly characterized, with prior measurements made using an older technique in the 1990s on only a few samples from one ice core. No published carbon monoxide isotope measurements from northern hemisphere ice cores are currently available. Researchers on this project will collect a new large diameter ice core near Summit, Greenland using the Blue Ice Drill (BID), providing ice from 80 to 170 meters depth (air age from about 1960 to about 1600 AD). Continuous measurements of carbon monoxide concentration will provide a high-resolution record over the entire ice core and identify ice layers where carbon monoxide is well preserved. High-precision discrete analyses of carbon monoxide concentration and isotopic composition will then target ice from these layers. Continuous analyses of trace chemistry and discrete analyses of trace organics will also be conducted to establish the ice core chronology and improve understanding of mechanisms of in situ carbon monoxide production in ice. Atmospheric histories for carbon monoxide concentration and isotopic composition will be derived using a combination of firn-ice gas transport and inverse models, and the implications for pre-industrial carbon monoxide budget will be investigated with the use of a climate-chemistry model. This approach maximizes the chance of obtaining a reliable history of carbon monoxide concentration and isotopic composition through careful site selection and the application of novel ice drilling and analytical techniques. Results from the study will be made available to the scientific community and the general public through the NSIDC and NOAA Paleoclimatology data centers. The work will contribute to the training of two graduate and 2 undergraduate students, support an early career investigator, and establish several new collaborations among the investigators.

Logistics Summary:
Researchers on this collaborative project between Petrenko (1406236, Rochester, LEAD), McConnell (1406219, DRI), Mak (1405817, Stonybrook), and Tsigaridis (1404158, Columbia) will continue work begun under the lead PI's existing 14C project (1203779). The main goal of the project is to provide a first reliable atmospheric reconstruction of carbon monoxide (CO) and its isotopes from Greenland ice back to 1600 AD. During a single summer of field work, 2015, researchers will obtain up to 100 m of large diameter ice core. They will work near the historical Euro core site, at a site they are calling PLACE camp, using the Blue Ice Drill (BID) between 80 and 170 m depth. The cores will be transported via ANG to Kangerlussuaq, and then back the US on a cold deck flight for eventual storage and processing at the National Ice Cores Laboratory (NICL).

For the combined Petrenko led projects (1203779 and 1406236), CPS will provide ANG airlift for the field team and cargo; en route user days at Kangerlussuaq and Summit Station; field camp and safety equipment from the CPS inventory; construction support for camp setup / takedown and various support requirements (i.e. core storage trench, melter platform, and sample trays); provision of generator support and fuel; provision of food; CPS Camp Coordinator support; and shipment for up to 100 ice core boxes of frozen samples Summit > Kangerlussuaq > NY > NICL.

A thorough understanding of cosmogenic C-14 in firn and shallow ice will likely enable the use of C-14 in ice for one or more of the following applications:
 1) If a relatively large amount of cosmogenic 14C is present in ice below the depth at which air bubbles become sealed off, it will be useful as a tracer for past cosmic ray flux. The investigators believe that this is the likely case for 14C-carbon monoxide. 2) If the amount of retained in-situ-produced 14C-carbon dioxide is relatively small compared to 14C-carbon dioxide from trapped air, the study will demonstrate the validity of using 14C-carbon dioxide for absolute dating of ice cores; this has long been a target of ice core studies. 3) If the amount of retained in-situ-produced 14C-methane is relatively small compared to 14C-methane from trapped air, the study will demonstrate the validity of using 14C-methane in glacial ice for determinations of the fossil fraction of the past methane budget, including releases from methane clathrates. This project will establish a new international collaboration between University of Rochester (UR) and University of Bern and result in novel laboratory and field analytical systems.

This collaboration between Petrenko (1203779, U of Rochester), Severinghaus (1203686, UCSD) and Brook (1204084, OSU) will conduct a 3 year project drilling in the vicinity of Summit Station (~5 km away from the Station proper). Logistic details located under 1203779.

Science Summary:
In 2010, the observatory at Summit, Greenland, in the center of the Greenland Ice Sheet (GIS), was expanded to include a comprehensive suite of cloud-atmosphere observing instruments including microwave and infrared spectrometers, cloud radar, depolarization lidar, ceilometer, precipitation sensor, sodar, and a twice-daily radiosonde program. This observing effort was termed ICECAPS (Integrated Characterization of Energy, Clouds, Atmospheric state, and Precipitation at Summit). Continuation of the work was approved / funded late summer 2013 to allow for continuous operation, with moderate enhancements to include new precipitation measurements. Measurements from this expanded instrument suite will be used to derive critical baseline atmospheric data products including: Atmospheric State - tropospheric temperature, moisture, and wind profiles, Cloud Macrophysics - occurrence, vertical boundaries, temperature, Cloud Microphysics - phase, water content, and characteristic particle size, and Precipitation - type and rate. Together these products, when combined with similar ongoing measurements at Summit, can be used to study processes that impact the surface energy budget and precipitation at the site, as well as addressing questions related to atmospheric stability, cloud phase composition, and the persistence of stratiform clouds. It is further anticipated that these observations will continue to be used by a broad cross-section of the scientific community to promote understanding of GIS and Arctic climate, validate satellite observations, and evaluate model simulations. Graduate students play significant roles in most aspects of this project, gaining valuable experience with polar field work, operating instruments, and processing data. In addition, this research team has developed a unique education and outreach plan to work with students from local schools using simple, proxy instrumentation to help develop their understanding of atmospheric principles and observations, and to enhance the scientific curriculum in their schools via a wide range of outreach activities.

Logistics Summary:
Researchers on this collaboration between Walden (1414314, WSU), Turner (1304692, U of OK), Shupe (1303879, CU) and Bennartz (1304544, U of WI) will continue work begun under NSF grant 0856773 "ICECAPS". Researchers will continue an intensive cloud experiment at Summit with fieldwork from late spring 2014 through late spring 2018. Logistic details under 1414314.

Science Summary:
This grant supports a 5-year research project that explores extreme solar events and their effects on Earth. The project draws together scientists from many different disciplines to tackle a question of growing importance to our society: What extremes of solar activity produce powerful space-weather- effects at Earth that pose risks to society? We know that the Sun is capable of creating explosive events and that these events generate dangerous streams of charged particles that can arrive at Earth moments later. We also know that these solar particles can slam into our atmosphere and affect its chemistry, including in the ozone layer. These same particles can cripple satellite systems we depend on in everyday life (GPS, communications, etc.), and pose radiation risks to astronauts and even to airline passengers. However, we only have measured such events during the space age over the past 50 years, a brief wink of time compared to the age of the Sun and solar system. "Sun-to-Ice" investigates extreme solar events and their effects on Earth by detailed studies of the physical processes linking the Sun to Earth. The researchers will study how solar eruptions lead to giant blasts of material called coronal mass ejections and how these evolve in space once they leave the Sun. The PI will investigate the processes by which these extreme solar events accelerate charged particles and how these particles are transported from the Sun to Earth, and how they enter the Earth's atmosphere and how they change its chemical properties. Finally, researchers also will study how chemical signatures of these events are recorded in ice near the poles. By confirming a link between extreme solar activity and the ice-core record, deep ice cores can help researchers unravel the history of ancient solar activity and establish the range of extreme solar events. This project seeks to make breakthroughs in diverse, complex and interlinked systems that cross the boundaries between space physics, atmospheric, and ice core science, yielding insights into the genesis of extreme events and their impact on Earth.

Logistics Summary:
This grant supports a study of the physical processes of the Sun-Earth system including coronal mass ejections (CME) and solar energetic particle acceleration and transport. As part of this systemic study, researchers will study how chemical signatures of solar events (like CMEs) are recorded in ice near the poles. Beginning in 2012 and for four consecutive years after, science technicians on site at Summit Station, Greenland, will perform six months of daily sampling following a potential CME event. (There were no CME events in 2013 or 2014). The PI or his designee will request the sampling support as needed; no project personnel are expected to deploy to Greenland.

CPS will provide Air National Guard (ANG) cargo support for necessary sampling supplies and potential retro cargo of snow samples, and--dependent on a qualifying solar event--science-technician support to collect daily samples for up to 6 months each time. The PI will arrange and pay for all other support through the grant.

Science Summary:
A part of the NASA-sponsored PARCA (Program in Arctic Regional Climate Assessment) project, researchers on this NSF co-funded project have installed and are currently maintaining 18 Automatic Weather Stations (AWS). Each AWS is equipped with a number of instruments to sample the following: -air temperature, wind speed, wind direction, humidity, pressure -accumulation rate at high temporal resolution to identify and resolve individual storms -surface radiation balance in visible and infrared wavelengths -sensible and latent heat flux fluxes -snowpack conductive heat fluxes Hourly average data are transmitted via a satellite link (GOES or ARGOS) throughout the year. In addition, measurements are stored in solid state memory. The system is powered with two 100 Ah batteries, charged by a 10 or 20 W solar panel. The satellite data-link is powered by two separate 100 Ah batteries connected to a 20 W solar panel. This setup guarantees continuous data recordings and storage, even in the case of satellite transmission failure. The expected lifetime of the instrumentation is 5 years. PARCA GC-Net Automated Weather Stations (AWS) are equipped with communication satellite transmitters that enable near-real time monitoring of weather conditions on the Greenland ice sheet. Transmission latency is as short as 4 minutes, typically 1-2 hours, and occasionally as long as 48 hours.

Logistics Summary:
In 1995, the PI began to develop a network of Automated Weather Sites (AWS) on the Greenland ice cap. Each year since then, a team of four to five travels to the project's sites via Twin Otter for maintenance, repairs, and upgrades. Additionally, the team tent-camps at Swiss Camp for several weeks to conduct more intensive measurements related to the state of the ice sheet. These include monitoring ablation in the Jakobshavn region (in collaboration with Dr. Jay Zwally [NASA-GSFC]); measuring accumulation variability, mass transfer, and surface energy balance. In 2007, one person will visit Summit Station to install a thermistor string to capture hourly temperature profiles in the upper ~100 m of ice. The researcher will use an empty borehole. The data will help the team reconstruct surface temperature history on a multi-decadal to century scale. The researcher will spend about a week at Summit setting up the experiment, which may remain in place for several years. Also in 2007, the PI’s graduate student will base from Ilulissat and fly a NOAA-funded UAV experiment in early May and again in July to collect high-resolution laser data around Swiss Camp during the pre-melt and melt season. These data will help researchers calculate surface water storage on the ice sheet. New at Swiss Camp in 2008, a UAV equipped with laser instruments to collect high-resolution data about surface water storage.This NOAA-funded project uses a UAV based in Ilulissat to collect high-resolution laser data around Swiss Camp during the pre-melt and melt season. These data are used to calculate surface water storage on the ice sheet. The information contributes to the PI’s sub-glacier hydrological modeling study (“GPS Network Maintenance,” above). The PI’s graduate student, John Adler, will fly the UAV in early May and again in July to collect the data in the second and final field season for this project. In 2009, mid-April to mid-May, the researchers will maintain the automatic weather station network. In the south, they will service the Dye-II, Saddle, NASA SE and S-Dome stations, and during the Swiss Camp put in the CP1 and NASA-U stations. While at Swiss Camp, the team will service the profile JAR2, JAR1, and CU/ETH. They will continue the effort to monitor ablation along a transect from Swiss Camp to the ice margin. The Swiss Camp team will service eight receivers in the GPS network in collaboration with Dr. Jay Zwally (NASA-GSFC). They will continue to collect high-resolution surface topography data using Trimble Pathfinder differential GPS measurements along several transects in the lower ablation region. In addition, they will acquire a set of QuickBird satellite imagery during the onset of melt and the melt period to monitor the spatial variation and extent of snow fields, lakes, and surface hydrological channels in the ablation region. This project has collected a number of ground penetrating radar (GPR) profiles along the western slope of the ice sheet (Jakobshavn and Kangerlussuaq region) in previous field seasons (1999, 2000, 2003). Data analysis showed that the accumulation could vary up to 40% between the trough and the ridge of the undulation. (Surface topography with scale length of several kilometers plays an important role for the spatial variability of accumulation, mass transfer, and surface energy balance.) The team repeated some of these GPR measurements during the spring 2007 field season along the same profiles to verify the recent accumulation changes and high percolation events in that region. In addition to science research, the PI will host two media visits in spring 2009: (a) MISCHIEF FILMS, Austrian documentary film about Albert Schweitzer. The crew will participate for one day and one night during the southern AWS maintenance trip. (b) National Geographic, documentary called “The Big Picture.” The crew visits Swiss Camp May 3-5. They will organize their own helicopter flight from Ilulissat to Swiss Camp and back. In 2010, DRI's Joe McConnell and an ICDS driller will join the AWS maintenance visits to Humboldt and TUNU to drill shallow cores for analysis related to the NEEM deep drilling project (0909541). Participant travel for McConnell and the driller to Kangerlussuaq will be carried under his NSF grant record. In 2011, a team of about eight will arrive in Greenland around 1 May. They will first travel via Twin Otter to Swiss Camp to install new extension poles on the GPS network; and to maintain/upgrade (with new satellite transmitters) the AWS network stations JAR2, JAR1, Swiss Camp, and Crawford Point. Around Swiss Camp and in the lower ablation region the team will map sub-glacial melt channels using a new MALA ground penetrating radar with a 20 MHz antenna. They also will install new seismic stations close to Swiss Camp and in the lower ablation region close to a moulin. Researchers for NSF grant 0909454, Ginny Catania, PI, also will visit Swiss Camp at the same time to work on the project’s GPS experiment. Researchers also will visit AWS stations in the north of Greenland (NEEM, GITS, Petermann, Tunu-N, Humbold, NASA-U, and NASA-E) and in the south (Dye-II, Saddle, NASA-SE, and Saddle) for maintenance service. At Summit researchers will maintain the 50m Swiss Tower and the Baseline Surface Radiation Network (BSRN); these provide the basing meteorological and radiation data for other Summit researchers. In 2013, a team of four will fly commercially to Kanger for a Twin Otter put-in to Swiss Camp in early May for a three-week effort at the camp. Three more researchers will arrive mid-May on a helicopter flight arranged and paid for by the PI’s institution (CU). The three new arrivals plus one original team member will depart a few days later on another CU-chartered helicopter flight. The Twin Otter will return to Swiss camp in late May to pick up the remaining team members and begin transporting them to the southern set of AWS stations (Dye-II, NASA-SE, and Saddle), with air support based from Kangerlussuaq. A team of four will then depart Kangerlussuaq via Twin Otter to begin visiting the northern AWS sites (NEEM, GITS, Petermann, Tunu-N, Humbold, NASA-U, and NASA-E), working out of Daneborg, Qaanaaq, and NEEM. The team will wrap up Twin Otter work with a visit to Summit Station, overnighting to service the Swiss Tower and the Baseline Surface Radiation Network (BSRN), which provide the basing meteorological and radiation data for other Summit researchers. In mid-August, a team will return to Swiss Camp and the Moulin Site via helicopter out of Ilulissat to make late-season repairs to the camp, which sustained considerable damage during the 2012 melt season. After about one week at camp, the team will depart via helicopter and commercial air. In 2014, a team of six will fly commercially to Kangerlussuaq for a Twin Otter put-in to Swiss Camp in early May. The team will spend ~two weeks based at the camp. The Twin Otter will return to Swiss camp in mid-May to pick up the team and begin transporting them to the southern set of AWS stations (Dye-II, Saddle, NASA-SE, and Saddle), with air support based from Kangerlussuaq. A team of four will then depart Kangerlussuaq via Twin Otter to begin visiting the northern AWS sites (NEEM, GITS, Petermann, Tunu-N, Humboldt, NASA-U, and NASA-E), working out of Daneborg, Qaanaaq, and NEEM. The team will wrap up Twin Otter work with a visit to Summit Station, overnighting to service the Swiss Tower and the Baseline Surface Radiation Network (BSRN) which provide the basing meteorological and radiation data for other Summit researchers. In 2015, a team of six will fly commercially to Kangerlussuaq for a Twin Otter put-in to Swiss Camp in early May. The team will spend ~two weeks based at the camp. The Twin Otter will return to Swiss camp in mid-May to pick up the team and begin transporting them to the southern set of AWS stations (Dye-II, NASA-SE, and Saddle), with air support

CPS will provide ANG cargo coordination from the U.S., ANG support for passenger and cargo to/from Summit Station, chartered air support within Greenland, lodging and user days, camping gear, fuel, and safety and communications equipment. Costs will be covered in the following ways: NASA will pay 100% of Swiss Camp support costs. NSF and NASA will each pay for 50% of the remaining activities. NSF will recoup costs from NASA via an interagency funds transfer NASA > NSF. The PI will arrange and pay for other work directly.

Science Summary:
Most knowledge about the deeper interior of the earth is derived from seismological records. Seismic waves generated by earthquakes travel through the globe and sample its major structures on the way. Important information about seismic velocities and densities, structural boundaries, mineral composition, temperature and pressure regimes etc are hidden in each recorded seismogram and can be retrieved by inverse methods. To obtain a complete picture, globally distributed high quality broadband seismological stations are required to record a full seismologically range in terms of frequency content (10**2 – 10**-6 Hz) and dynamic range (10**-9 – 10**-1 m/s). The technical equipment of the GEOFON network fullfills these requirements and is installed in 50 stations worldwide. (Near) real-time data transmission (via the Internet) from most stations makes the GEOFON data immediately available to the scientifc community and provides a perfect tool for rapid determination of earthquake source parameters for scientific purposes but also for earthquake and tsunami early warnings and for use by disaster management. Both near real-time and archive data are openly available to the community from the GEOFON Data Center and are shared with other national and international data centers such as the european ORFEUS Data Center in De Bilt (Netherlands) and the global FDSN/IRIS Data Center (Seattle, USA).

Logistics Summary:
This project makes broadband seismological recordings of global earthquakes at Summit, Greenland. Formerly a part of the temporary GLATIS network, project responsibility has been turned over to GFZ Potsdam. Summit instruments have been included in that institute's GEOFON network. The PI (Hanka, then Strollo starting in 2015) will visit Summit Station annually to service and maintain the project's seismological station. Over the years, in addition to the scheduled maintenance, project personnel have visited Summit for various other project needs: In 2002, they installed an upgraded datalogger for the seismological station and a "Seiscomp" box that connected the station to the Summit LAN for Internet real-time data transmission; in 2004, another major station upgrade overcame technical problems and minimized required local support; finally, in 2007, two technicians raised and relocated the seismometer bunker, routing power and communications connections out of the Temporary Atmospheric Watch Observatory. In 2009, a technician will return to Summit in May to conduct minor maintenance on the seismometer. Station staff will assist the technician as needed with excavation of the bunker and maintenance activities. Year-round, science technical staff will re-level the instrument and provide as-needed assistance. In 2010, a team of two researchers will return to Summit in July. The seismometer bunker will be raised and relocated to a new site so that power and communications can continue to be connected out of the Temporary Atmospheric Watch Observatory, which is also being relocated during this time. Station staff will assist the technicians as needed with excavation of the bunker and maintenance activities. Year-round, science technical staff will re-level the instrument and provide as-needed assistance. In 2011, one researcher will return to Summit in mid-June to conduct minor maintenance on the seismometer. Summit staff will assist the researcher as needed with excavation of the bunker and maintenance activities. Year-round science technical staff will re-level the instrument and provide as-needed assistance. In 2012, two researchers will return to Summit Station in July to conduct minor maintenance on the seismometer. In 2013, two researchers will return to Summit Station in July with the following objectives: (1) relocate the seismometer to a new trench, and (2) replace the cable between the TAWO and the new seismometer trench. Summit Station staff will assist the researchers as needed with excavation of the bunker and maintenance activities. Year-round, science technical staff will re-level the instrument and provide as-needed assistance. In 2014, no researchers will deploy to Summit Station. Instead, station staff will assist with excavation of the bunker and maintenance activities as needed. Year-round, science technical staff will re-level the instrument and provide as-needed assistance. In 2015, two researchers will deploy to Summit Station in June to perform maintenance on the seismometer system, including relocating it to a new vault, raising all cables above the snow surface and checking out all hardware. Year-round, science technical staff will re-level the instrument, maintain data and power cables above the snow surface and provide as-needed assistance. No researchers will deploy in 2016. Instead, station technical staff replaced a broken seiscompbox. The replacement box is expected in fall 2016; when functioning, it will allow remote mass centering. Two researchers will visit Summit in May-June 2017 to perform maintenance on the seismometer system, including relocating it to a new vault, raising all cables above the snow surface, and checking out all hardware.

CPS will provide travel to/from Summit Station, Summit Station user days, and access to infrastructure (for years with participant travel) and science technician support year-round (re-leveling the instrument, maintain data and power cables above the snow surface and provide as-needed). The PI will pay NSF directly for costs associated with this support. All other logistics will be provided by the PI.

Science Summary:
The main goal of this work is to provide the first reliable record of pre-industrial carbon monoxide (CO) concentration and stable isotope composition in the Arctic atmosphere, which will also be representative of a large part of the Northern Hemisphere. Carbon monoxide concentrations are a crucial component of any complete modern or past atmospheric data set because CO plays a key role in global atmospheric chemistry by being the largest single sink of hydroxyl radicals in the lower atmosphere. Carbon monoxide concentration in combination with stable isotopes is also a powerful tracer for large-scale biomass burning variations. Pre-industrial carbon monoxide concentration in the northern hemisphere (where anthropogenic impacts have been by far the strongest) is poorly characterized, with prior measurements made using an older technique in the 1990s on only a few samples from one ice core. No published carbon monoxide isotope measurements from northern hemisphere ice cores are currently available. Researchers on this project will collect a new large diameter ice core near Summit, Greenland using the Blue Ice Drill (BID), providing ice from 80 to 170 meters depth (air age from about 1960 to about 1600 AD). Continuous measurements of carbon monoxide concentration will provide a high-resolution record over the entire ice core and identify ice layers where carbon monoxide is well preserved. High-precision discrete analyses of carbon monoxide concentration and isotopic composition will then target ice from these layers. Continuous analyses of trace chemistry and discrete analyses of trace organics will also be conducted to establish the ice core chronology and improve understanding of mechanisms of in situ carbon monoxide production in ice. Atmospheric histories for carbon monoxide concentration and isotopic composition will be derived using a combination of firn-ice gas transport and inverse models, and the implications for pre-industrial carbon monoxide budget will be investigated with the use of a climate-chemistry model. This approach maximizes the chance of obtaining a reliable history of carbon monoxide concentration and isotopic composition through careful site selection and the application of novel ice drilling and analytical techniques. Results from the study will be made available to the scientific community and the general public through the NSIDC and NOAA Paleoclimatology data centers. The work will contribute to the training of two graduate and 2 undergraduate students, support an early career investigator, and establish several new collaborations among the investigators.

Logistics Summary:
This collaborative project between Petrenko (1406236, Rochester, LEAD), McConnell (1406219, DRI), Mak (1405817, Stonybrook), and Tsigaridis (1404158, Columbia) will continue work begun under the lead PI's existing 14C project (1203779). This new award will be folded into the existing logistics and fieldwork that will be conducted ~10km from Summit Station again in 2015. The main goal of the project is to provide a first reliable atmospheric reconstruction of carbon monoxide (CO) and its isotopes from Greenland ice back to 1600 AD. Logistic details under 1406236.

Science Summary:
In 2010, the observatory at Summit, Greenland, in the center of the Greenland Ice Sheet (GIS), was expanded to include a comprehensive suite of cloud-atmosphere observing instruments including microwave and infrared spectrometers, cloud radar, depolarization lidar, ceilometer, precipitation sensor, sodar, and a twice-daily radiosonde program. This observing effort was termed ICECAPS (Integrated Characterization of Energy, Clouds, Atmospheric state, and Precipitation at Summit). Continuation of the work was approved / funded late summer 2013 to allow for continuous operation, with moderate enhancements to include new precipitation measurements. Measurements from this expanded instrument suite will be used to derive critical baseline atmospheric data products including: Atmospheric State - tropospheric temperature, moisture, and wind profiles, Cloud Macrophysics - occurrence, vertical boundaries, temperature, Cloud Microphysics - phase, water content, and characteristic particle size, and Precipitation - type and rate. Together these products, when combined with similar ongoing measurements at Summit, can be used to study processes that impact the surface energy budget and precipitation at the site, as well as addressing questions related to atmospheric stability, cloud phase composition, and the persistence of stratiform clouds. It is further anticipated that these observations will continue to be used by a broad cross-section of the scientific community to promote understanding of GIS and Arctic climate, validate satellite observations, and evaluate model simulations. Graduate students play significant roles in most aspects of this project, gaining valuable experience with polar field work, operating instruments, and processing data. In addition, this research team has developed a unique education and outreach plan to work with students from local schools using simple, proxy instrumentation to help develop their understanding of atmospheric principles and observations, and to enhance the scientific curriculum in their schools via a wide range of outreach activities.

Logistics Summary:
Researchers on this collaboration between Walden (1414314, WSU), Turner (1304692, U of OK), Shupe (1303879, CU) and Bennartz (1304544, U of WI) will continue work begun under NSF grant 0856773 "ICECAPS". Researchers will continue an intensive cloud experiment at Summit with fieldwork from late spring 2014 through late spring 2018. Logistic details under 1414314.

Science Summary:
Ultra-high energy (UHE) neutrino astronomy is a rapidly evolving field that sits at the crossroads of particle physics, astronomy, and astrophysics. Neutrinos travel virtually unimpeded through the Universe, making them unique messenger particles for cosmic sources, carrying information about very distant sources that would otherwise be unavailable. Detection of ultra-high energy neutrinos could also reveal the origin of cosmic rays. Current and recent efforts to detect UHE neutrinos (the balloon-borne ANITA experiment, the ARA effort at the South Pole, and ARIANNA on the Ross Ice Shelf) have utilized radio detection techniques, searching for coherent, impulsive radio signals that are emitted as electromagnetic particle cascades are induced by neutrinos interacting with a dielectric such as ice. UHE neutrino detection requires enormous volumes of a naturally-occurring dielectric material that allows radio signals to pass through without significant attenuation. Current experimental efforts monitor enormous volumes of Antarctic ice, whose radio attenuation properties have been directly measured by us and our collaborators at multiple locations in Antarctica (Barrella et al. 2010, Besson et al. 2008, Barwick et al. 2005). ANITA searches for neutrinos interacting within all of the ice that is within its 700 km horizon while the payload is at float altitude, while ARA and ARIANNA both instrument smaller sections of ice directly on (or just below) the surface. If the neutrino detectors that are currently being developed in Antarctica are successful, the natural follow-up experiment would eventually be a similar detector installed in the Northern hemisphere to catalogue the half of the sky that is not visible from Antarctica. Determining the radio attenuation length in ice at Summit Station would be the first step toward site exploration for such a project. The researchers will perform similar measurements at Summit Station in Greenland to those that have been made in Antarctica to determine if the ice there exhibits similar low-loss properties between 200-1200 MHz and measure the radio noise environment at Summit Station. Previous radio measurements of ice properties at Summit Station have been made by geologists (Paden et al. 2005) as a by-product of measurements that characterize the rock interface at the bottom of the ice sheet, and hint at very long attenuation lengths ( > 500 m), rivaling those measured in the Antarctic.

Logistics Summary:
Researchers will conduct an experiment to determine the radio attenuation length in ice at Summit Station, to understand if the site exhibits similar low-loss properties as have been observed in Antarctica. Such characteristics are important for the detection of neutrinos, and if the neutrino detectors that are currently being developed in Antarctica are successful, Summit Station may be a suitable location for a similar detector installed in the Northern hemisphere to catalogue the half of the sky that is not visible from Antarctica. During the 2013 field season, a team of four will conduct a site characterization visit to Summit Station to directly measure the radio attenuation length and birefringence of the ice as well as make measurements of the radio noise environment at the site. Previous radio measurements of ice properties at Summit Station have been made by geologists as a by-product of characterization of the rock interface at the bottom of the ice sheet, and hint at very long attenuation lengths ( > 500 m), rivaling those measured in the Antarctic. Researchers will perform a direct measurement of ice properties to compare with measurements made in Antarctica using the same techniques. In June 2015, researchers will return to Summit Station in staggered teams of two to test a phased array of radio antennas in situ. They will establish a day-camp at the DISC borehole to deploy the array in different configurations while transmitting calibration signals from various surface locations. They will temporarily pump drill fluid out of the borehole while doing their tests. Fluid will either be pumped down the borehole after the group is finished or will be retro-ed if CPS determines a cost-effective method. The group will bring their own pump and associated PPE, utilizing containment provided onsite. CPS staff will assist with site set-up and to ensure the pump mates with the provided generator. The group will commute daily to the DISC borehole by foot and will occasionally access the Summit snowmobiles and sleds for days requiring cargo transport.

CPS will provide Air National Guard (ANG) coordination for the field team and cargo; reservations for KISS user days in Kangerlussuaq; user days at Summit Station; FEMCO assistance for site set-up; occasional use of the Summit snow machines and sled; and dedicated allocation of generators, fuel, tents, and communication/safety equipment. NSF will recoup costs associated with this support directly from the PI’s institute. The PIs will make all other arrangements and pay for them through the grant.

Science Summary:
Through this grant, Dartmouth will lead the U.S. contributions to JSEP for the next three years (starting in February 2015). The leadership role will include: sending a small team of graduate student and postdoctoral researchers with polar field experience, along with a Dartmouth faculty member, to Greenland to lead field science education in the JSEP programs; continued training of Dartmouth graduate students and postdoctoral researchers in cross-cultural science communication to advance outreach in Greenland and share this training more broadly with the Dartmouth community; hosting planning meetings and workshops to design the curriculum for Science and Education Week and to help coordinate efforts by all parties engaged in JSEP; working with our partners in Greenland to increase the visibility of JSEP in Greenland; and sharing and assessing the results of our work through presentations in education-focused symposia at national meetings and publications in scholarly journals. As an outcome of the NSF IGERT grant to Dartmouth to develop the Polar Environmental Change program, these researchers have many years of experience with science, outreach, and the logistics of working in Kangerlussuaq and at Summit, Greenland, and the students, postdocs, and faculty have contributed significantly to the JSEP programs since 2011. In addition, they have a strong network of colleagues and scholars in Greenland that can continue to help us increase participation and engagement of students and teachers from Greenland. A Dartmouth-JSEP partnership is a natural and synergistic collaborative opportunity to provide significant international Arctic science education and outreach to students from Greenland, Denmark, and the U.S., with broader impacts for international communities of stakeholders, future leaders, and polar scientists.

Logistics Summary:
This grant supports the Joint Science Education Project (JSEP) program in Greenland. The Joint Committee, a high-level forum involving the Greenlandic, Danish and U.S. governments, initiated JSEP in 2007 to educate an international community of high school students and teachers from each of the three nations about the causes and consequences of rapid environmental change. The goals of JSEP include inspiring the next generation of polar scientists, building strong networks of students and teachers among the three countries, and providing an opportunity to practice language and communication skills by taking assemblages of students from the three nations to Greenland to observe polar science in action. From 2015 to 2017, Dartmouth JSEP team participants will travel to Greenland each summer to participate in the Kangerlussuaq Science Field School and lead Science and Education week at Summit Station. The PI and postdoctoral fellow will also travel to Nuuk to advance partnerships with Greenlandic institutions. The 2016 JSEP effort features two field visits: a spring preparatory trip, and the June summer intensive, which will feature a PolarTREC teacher. This season plan covers support for the first trip. In April two graduate students will visit Kangerlussuaq, travelling to and from Greenland via the ANG. They will travel by truck to their field site, establish a tent camp, and set up a winter ecology research module for the JSEP high school students. They will pause in Kangerlussuaq on the way to and from the field, staying at the KISS for a couple of days on either end of the trip.

CPS will provide ANG coordination and stateside commercial travel for U.S. participants, user days for GoG building, Kanger-based vehicle transport, student grade materials, ECW gear, and limited use of CPS inventory. For the April 2016 trip only, CPS will provide: ANG travel coordination and provide camping, field, and safety/communications gear; KISS user days and truck rental will be paid through the grant. All other support will be organized and paid through the grant.

Science Summary:
In 2010, the observatory at Summit, Greenland, in the center of the Greenland Ice Sheet (GIS), was expanded to include a comprehensive suite of cloud-atmosphere observing instruments including microwave and infrared spectrometers, cloud radar, depolarization lidar, ceilometer, precipitation sensor, sodar, and a twice-daily radiosonde program. This observing effort was termed ICECAPS (Integrated Characterization of Energy, Clouds, Atmospheric state, and Precipitation at Summit). Continuation of the work was approved / funded late summer 2013 to allow for continuous operation, with moderate enhancements to include new precipitation measurements. Measurements from this expanded instrument suite will be used to derive critical baseline atmospheric data products including: Atmospheric State - tropospheric temperature, moisture, and wind profiles, Cloud Macrophysics - occurrence, vertical boundaries, temperature, Cloud Microphysics - phase, water content, and characteristic particle size, and Precipitation - type and rate. Together these products, when combined with similar ongoing measurements at Summit, can be used to study processes that impact the surface energy budget and precipitation at the site, as well as addressing questions related to atmospheric stability, cloud phase composition, and the persistence of stratiform clouds. It is further anticipated that these observations will continue to be used by a broad cross-section of the scientific community to promote understanding of GIS and Arctic climate, validate satellite observations, and evaluate model simulations. Graduate students play significant roles in most aspects of this project, gaining valuable experience with polar field work, operating instruments, and processing data. In addition, this research team has developed a unique education and outreach plan to work with students from local schools using simple, proxy instrumentation to help develop their understanding of atmospheric principles and observations, and to enhance the scientific curriculum in their schools via a wide range of outreach activities.

Logistics Summary:
Researchers on this collaboration between Walden (1414314, WSU), Turner (1304692, U of OK), Shupe (1303879, CU) and Bennartz (1304544, U of WI) will continue work begun under NSF grant 0856773. Researchers will continue an intensive experiment to measure atmospheric properties at Summit with fieldwork running continuously from late summer 2013 through summer 2018. The suite of ICECAPS instruments was originally installed in 2010 and since then the project has been maintained by year-round science technician support and summer maintenance visits by the research team. During 2014, four members of the research team will deploy to Summit station for instrument support and upgrades. CPS will provide technician support at the station year-round. The CPS science technician will continue to monitor project instruments and oversee a twice daily radiosonde program. In subsequent years, a research team of four to five participants will travel to Summit Station each spring / summer to provide instrument support. During 2015, four to five members of the research team will deploy to Summit Station for instrument support and upgrades. CPS will provide technician support at the station year-round. The CPS science technician will continue to monitor project instruments and oversee a twice-daily radiosonde program. During 2016, field team members will deploy to Summit Station in June to support instrument maintenance, upgrades and the Mobile Science Facility relocation. The scientists will reinstall the multi-angle snowflake camera, sent off-station for repairs during early season, when it is shipped back to Summit mid-season. CPS science technicians will continue to monitor project instruments and oversee the twice-daily radiosonde program year-round.

CPS will provide Air National Guard (ANG) coordination for the field team and cargo; coordination of candidate screening, hiring, management, travel and accommodations for year-round science technician; science technical services; in-transit user days in Kangerlussuaq; access to the Summit Station infrastructure and services, relocation of the Mobile Science Facility); helium provision and shipment; liquid nitrogen provision and shipment; provision and shipment of radiosondes, parachutes, and balloons. The PIs will make all other arrangements and pay for them through their respective grants.
