Science Summary:
The stable isotopic records from the Greenland Ice Sheet are the gold standard for understanding climate variations in the Arctic on decadal to millennial scales. While the basic tenets that underlie interpretation of isotopic information appear robust in a mean sense, meteorological and glaciological processes can confound simple interpretations. Processes of concern are variations in moisture sources, cloud processes, surface ablation, blowing snow and vapor diffusion in the firn. The project objectives are to resolve fundamental uncertainties in the controls on the isotopic composition of the ice sheet through a 3-year measurement campaign at Summit, Eureka and Reykjavik. The project will use measurements and modeling to evaluate 1) the degree to which oxygen isotopic composition and deuterium excess of snow capture variations in moisture sources versus cloud microphysical conditions, and 2) the degree to which blowing snow and vapor diffusion within the firn confound accurate interpretation of variability in the isotopic record. Continuous measurements of the isotopic composition of water vapor and daily measurements of the isotopic composition of freshly-fallen and blowing snow will be made at Summit, Eureka and Reykjavik. These will be combined with measurements of the amount, size distribution, and approximate habit of falling and blowing snow, turbulence measurements to evaluate snow lofting, surface latent heat flux (ablation and frost) and energy balance, and remote sensing of polar clouds and atmospheric structure. High-resolution firn cores will be drilled to reconcile the detailed isotopic measurements and modeling with glaciological records. The new isotope measurements will jump start an emerging international pan-Arctic cooperative network of isotope measurements, which complements Arctic observations under existing Arctic Observing Network activities. The advanced measurements at Summit enhance the site as a comprehensive observatory for monitoring and understanding Arctic change.

Logistics Summary:
This project involves an installation of instrumentation at Summit Station, Greenland, to measure processes that influence the isotopic composition of snow on the Greenland ice sheet. While the team will also work at Eureka and Reykjavik, measurements at Summit Station are the focal point of the study, and this support plan only details the work at Summit Station. The experiments will require a suite of meteorological and turbulence instruments, precipitation and cloud particle spectrometers, and a water vapor isotopic composition analyzer. The Summit Station work also includes snow collection and drilling a series of shallow ice cores (15-20m) to study firn properties. Researchers will work at Summit Station for four years, summer 2011 through summer 2014. During each season, a team of three to four will travel via the Air National Guard logistics chain to Summit Station, and spend two to four weeks working at the site. In the first year, instruments were installed on the existing 50-meter tower, with further instrumentation in an adjacent below-surface workspace. During the following two years the instruments were maintained by the Summit Station science technicians, with annual maintenance/upgrade visits from the researchers. In the final year the team will remove all instrumentation. In addition to working with the instrument suite as described above, each year the research team will conduct additional snow measurements and drill 3-5 shallow (15-20 meter) ice cores at locations around, and up to 5km away from, Summit Station. Processing of the core samples, and snow samples collected during storm events, will occur on-site prior to shipment to the home institution (samples will be retrograded as melt, not frozen). On-station science technicians will collect the snow samples and monitor the experiment when research personnel are off-station. CPS will ship processed samples as cargo requirements allow.

CPS will provide ANG support coordination for a team of three people and their cargo, accommodations and lodging in Kangerlussuaq, user days and access to Summit infrastructure and project workspace, procurement and installation and maintenance of a 10’x10’ below-surface structure, use of existing 50-meter tower, science technician support, and pre-deployment tower climb training. IDDO will provide drilling equipment. The PI will arrange for all other support—including that from Environment Canada and CANDAC at Eureka, and from University of Iceland in Reykjavik—and pay for it through the grant.

Science Summary:
There is growing evidence that aerosols over the Arctic may play an important role in the radiation balance of the region. In particular, light absorbing aerosols from biomass burning, fossil fuel combustion, and dust sources potentially have the greatest impact over Greenland snow. But scientists lack key measurements needed to accurately assess aerosol forcing over the ice sheet. For this reason, the researchers will measure crucial parameters needed to estimate the direct radiative forcing by aerosols over central Greenland. The measurements will include real-time measurements of aerosol physical and optical properties that will be used to estimate the aerosol single scattering albedo, and asymmetry parameter. Additionally measurements will be made of the wavelength-dependent optical depth, as well as the spectral surface reflectance. These data will serve as input to a radiative transfer model that will be used to estimate the direct aerosol radiative forcing at the surface and top of the atmosphere over Greenland. The scientists will also determine the sources and source regions of the direct radiative forcing through measurements of the aerosol chemical composition that will include ions, organic and elemental carbon, and specific elements. They hypothesize that dust, biomass burning and fossil fuel combustion aerosols often exert a positive direct radiative forcing many times greater than that of anthropogenic greenhouse gases. The scientists also expect that variability in snow albedo, which occurs on timescales of hours to days, exerts a significant influence on the direct aerosol forcing over Summit. Surface snow grain properties and surface snow chemistry will be determined at high temporal frequency to explore the link between the variability in these properties and the surface albedo through empirical observations, as well as detailed radiative transfer modeling within the snow pack. Overall, the research efforts will produce the first estimates of direct aerosol radiative forcing and the related aerosol sources, and source regions based on in-situ measurements above the Greenland Ice Sheet. The work will also highlight the potential role that variability in surface snow albedo, and related snow grain properties play in direct climate forcing by aerosols over central Greenland.

Logistics Summary:
The research team on this collaboration between 1023227 (Bergin, GA Tech, LEAD) and 1022996 (Dibb, UNH will focus on understanding the extent to which anthropogenic light-absorbing aerosols alter the radiation balance, and hence the climate of central Greenland. In addition, researchers will focus on better understanding how changes in the snow albedo impact aerosol forcing over the Greenland ice sheet. The researchers will conduct sampling in Summit's clean air sector from early May through late July during 2011. The field team will range from one to five researchers for the duration of the season, with personnel switch-outs dependent on the Air National Guard (ANG) flight schedule. At the end of the 2011 summer campaign, Summit science technicians will assume responsibility for the support and maintenance of an aerosol instrument that will stay at Summit through summer 2012. The aerosol instrument will be housed in the Temporary Atmospheric Watch Observatory (TAWO) structure. In 2011, PolarTREC teacher Kevin McMahon (0956825KM) will join the team.

CPS will provide ANG support for passengers and cargo, Kangerlussuaq user days at KISS, user days and access to Summit infrastructure, compressed gas, science tech support, and deployment of Sat Camp structures for the clean air sector sampling. The researchers will arrange for all other logistics and pay for them with grant funds.

Science Summary:
This project will quantify the relationship between the ice-free area of the Arctic Ocean and surrounding seas, and evaporation and precipitation in the Arctic. The methodology uses isotopic compositions of storm-by-storm precipitation samples, pan-Arctic meteorological data, satellite sea ice data, and numerical modeling. Precipitation samples will be collected at nine Arctic observatories, and by three high schools in Greenland. Samples will be analyzed for D/H and 18O/16O ratios. The track of a given storm will be reconstructed using reanalysis data and a Lagrangian trajectory algorithm. The project will yield a quantitative understanding of the links among sea ice, and moisture sources and amounts of Arctic precipitation, which comprise an important part of climate dynamics on a wide range of time scales. The results will be pertinent to the interpretation of ice core data, ice age dynamics, abrupt climate change, and global warming. This project also intends to integrate research with education and outreach, which will directly benefit participating arctic communities. The project aims to improve community understanding of how climate change research is done, by providing arctic students with new knowledge and skills, and by inspiring them to pursue advanced studies. At the same time, the PI's will benefit from learning traditional methods of observing, categorizing, and forecasting weather and climate from the indigenous communities participating in the study.

Logistics Summary:
For this research collaboration between 1022032 (Feng, Dartmouth) and 1023651 (Burkhart, UC Merced), the PIs will conduct precipitation sampling at nine Arctic Observatories: Barrow, Atqasuk and Fairbanks, Alaska; Eureka and Cambridge Bay, Canada; Summit Station, Greenland; Cherskii and Tiksi, Russia; and Zeppelin, Norway. In addition, the scientists will work with several communities on the western coast of Greenland to establish precipitation sampling stations there. Refer to 1022032 for logistics details.

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 continuous measurements of atmospheric composition at Summit Station to better understand changes occurring in the Arctic and Earth system. Continuous measurements include: 1. Halocarbon and other Atmospheric Trace Gases (HATS) Flasks: weekly to biweekly air sampling collection to measure trace gases that are important components of global halocarbon chemistry. These measurements have been ongoing since 2004. 2. Carbon Cycle Greenhouse Gas (CCGG) Flasks: weekly air sampling experiment 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 on-going since the 2003-2004 winter period. 3. In-situ Aerosol Sampling Suite: continual measurements of aerosol optical properties to determine aerosol radiative effects. These measurements were initiated in 2003 with an updated suite of instruments in 2009. 4. Surface ozone measurements: continual tropospheric air sampling efforts for ozone levels. These measurements were taken from 2000 to 2002, and from 2003 on. 5. Balloon-borne ozonesondes: measurements of year-round ozone atmospheric profiles. These measurements were first conducted during the late-winter of 2005. 6. In-situ Monitoring with the Chromatograph for Atmospheric Trace Species (CATS): a three-channel gas chromatograph performs hourly measurements of ozone depleting gases identified in the Montreal Protocol and amendments including nitrous oxide, sulfur hexafluoride, CFC-12, CFC-11, CFC-113, chloroform, methyl chloroform, and carbon tetrachloride. These measurements began in 2007. 7. Surface Meteorology: continuous measurements of surface meteorological properties to support both science and flight operations. These measurements have been continuous since summer 2005. 8. Surface Solar Radiation: continuous measurements of broadband solar and thermal radiation. These measurements began in 2013 with additional instruments added in 2016.

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. Two researchers will return in 2017 to demobilize the instruments.

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.

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; 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.

NSF_Award_Info: http://www.nsf.gov/awardsearch/showAward.do?AwardN...

Science Summary:
This project will quantify the relationship between the ice-free area of the Arctic Ocean and surrounding seas, and evaporation and precipitation in the Arctic. The methodology uses isotopic compositions of storm-by-storm precipitation samples, pan-Arctic meteorological data, satellite sea ice data, and numerical modeling. Precipitation samples will be collected at nine Arctic observatories, and by three high schools in Greenland. Samples will be analyzed for D/H and 18O/16O ratios. The track of a given storm will be reconstructed using reanalysis data and a Lagrangian trajectory algorithm. The project will yield a quantitative understanding of the links among sea ice, and moisture sources and amounts of Arctic precipitation, which comprise an important part of climate dynamics on a wide range of time scales. The results will be pertinent to the interpretation of ice core data, ice age dynamics, abrupt climate change, and global warming. This project also intends to integrate research with education and outreach, which will directly benefit participating arctic communities. The project aims to improve community understanding of how climate change research is done, by providing arctic students with new knowledge and skills, and by inspiring them to pursue advanced studies. At the same time, the PI's will benefit from learning traditional methods of observing, categorizing, and forecasting weather and climate from the indigenous communities participating in the study.

Logistics Summary:
For this research collaboration between 1022032 (Feng, Dartmouth) and 1023651 (Burkhart, UC Merced), the PIs will conduct precipitation sampling at nine Arctic Observatories: Barrow, Atqasuk and Fairbanks, Alaska; Eureka and Cambridge Bay, Canada; Summit Station, Greenland; Cherskii and Tiksi, Russia; and Zeppelin, Norway. In addition, the scientists will work with several communities on the western coast of Greenland to establish precipitation sampling stations there. From 2011 to 2014, researchers will either visit sites or have sampling conducted by local colleagues. In 2011, at the outset of the project, a team of 1-2 will travel to the sampling sites in Alaska and Greenland to see the facilities and the surrounding landscape and to teach sampling protocols to on-site staff. The researchers also will travel to several communities in Greenland to establish relationships / initiate sampling campaigns there. Russian sampling activities will be handled by CPS contractors- in addition, the PI will visit the Cherskii and Tiksi sites. In 2012, the PI will travel to Russia to meet with project collaborators. In mid-June, two people will travel to Cherskii. They will spend about a week at Cherskiy sampling and meeting with NESS personnel; the latter will provide ongoing support at Cherskii. After returning to Moscow, the team will travel by train to St. Petersburg. There, they will spend several days meeting with personnel from AARI who will provide sampling support at Tiksi. For Greenland 2012, two project members will return to Greenland to visit Kangerlussuaq. For 2013 and 2014, all sampling activities in Alaska, Greenland and Russia will be completed by local providers. Personnel at each site will collect precipitation samples on behalf of the project team for any storm that brings at least 2.5 mm water equivalent of precipitation. Samples will be shipped to Dartmouth College, where they will be analyzed. In 2016, the results of the isotope analysis completed by AARI will be released to the PI. (No personnel travel in 2016). CPS support focuses on the work at Cherskii/Tiksi, Alaska, and the Greenlandic sites.

If needed to support project activities, CPS is authorized to provide the following services: in Greenland, ANG coordination, commercial tickets for visits to villages, lodging, Kangerlussuaq user days, and access to the Summit infrastructure and science technical services. In Russia, subcontracts for Cherskiy and Tiksi support, shipping, and for the trip to Russia in 2012, user days at Cherskiy and per diem for St. Petersburg. In Alaska, lodging and truck days in Barrow and/or Atqasuk, as well as personnel for sampling in Atqasuk. In 2016, CPS will provide payment to AARI, the Russian subcontractor, to analyze some of the Russian samples and release the results of the sample analysis to the PI The PI will arrange all other logistics and pay for them through the grant.

Data: https://arcticdata.io/

Science Summary:
This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). This award will support the continuation of UVR (ultra-violet radiation) measurements at the Ultraviolet Spectral Irradiance Monitoring Network (UVSIMN) sites at Barrow, Alaska; and Summit, Greenland. UVR has been measured at Barrow since 1990 and at Summit since 2004. The UVSIMN is a contribution to the Arctic Observing Network (AON) and the Study of Environmental Arctic Change (SEARCH). The key "Intellectual Merit" of the project centers on acquiring data that can be used to advance knowledge of (1) the present and future solar radiation climate of the Arctic and (2) the factors that drive changes in UVR. For example, by combining UVR data with other measurements and modeling, parameterizations can be developed to predict future UVR intensities and improve climate models (e.g., CCMs). The "Broader Impacts" of this activity are to provide data to researchers in various disciplines, including satellite ground-truthing, and to educators for use in science courses and curricula. Undergraduate students at the University of Chicago will be involved in data processing and quality assessment/control. In collaboration with the Physical Sciences Division, the PI will provide summer courses for teachers in Chicago area schools where enrollments consist predominantly of minorities. Courses will be related to atmospheric and environmental research in the Polar Regions, and material will partly be drawn from results of the project.

Logistics Summary:
This grant supports continued UV-visible solar irradiance observing experiments. Via a subaward from the University of Chicago, Biospherical Instruments Inc. (BSI) will operate the NSF OPP’s Ultraviolet Spectral Irradiance Monitoring Network (UVSIMN). One of the UVSIMN's systems is located at Summit, Greenland. Another is operated in a laboratory at Ukpeagvik Iñupiat Corporation-Naval Arctic Research Laboratory at Barrow, Alaska. For information regarding the project’s prior logistics, see 0907819 (for 2009 only) and UVSIMN in this database. From 2010 to 2012, project personnel will visit Barrow, AK, and Summit Station, Greenland, as needed to perform system calibrations, service, and engineering upgrades to the system. On-site personnel will assist the research team in the areas of operational support, communications, IT, and logistics. Training of some science technicians will take place at BSI in San Diego, CA. A 2010 visit to Barrow will take place in March. Per the original grant plan, no visit to Summit by BSI personnel is scheduled for 2010 or 2011. At Summit, site operational assistance will be provided by on-station science technicians. At Barrow, as of March 2010, site operational assistance will be provided by local technicians in the employ of Arctic Administrators LLC. Work for this grant will continue under NSF grant 1203250, see that record for more details.

In Greenland, CPS support includes access to the Summit infrastructure, en-route transit costs between Scotia and Summit, and science technician services. In Alaska, after August, 2010, CPS will provide Barrow technical support via subcontracts with local service providers.

Institute: http://physsci.adelaide.edu.au/

Science Summary:
The aim of this project is to develop an expendable probe, which when attached to a standard radiosonde, will become the first low-cost routine technique to detect super-cooled liquid water in clouds. Beyond simply detecting super-cooled liquid, polarsondes will help to answer a number of scientific questions, by determining the ratio of liquid to ice in mixed-phase clouds. Current meteorological models use an ice fraction for clouds that is calculated from the temperature profile of the atmosphere. Even in the northern mid-latitudes, the few tests that have been made show that this assumed relationship is incapable of capturing the natural variability of the ice/liquid partitioning. Furthermore, observations by satellite have shown that clouds containing liquid water below 0°C are more frequent than current meteorological models predict. Radiosondes are the only routinely used meteorological device that can profile the interior of a cloud, but they are limited to sensing water vapor (as well as temperature and pressure) and not the liquid or solid phases. Polarsonde will overcome this limitation, by enhancing radiosondes to enable detection of super-cooled liquid water. It will distinguish the spherical liquid droplets from nonspherical ice crystals by exploiting the fact that they affect differently the polarization of the light that they scatter.

Logistics Summary:
This project is led by a PI from Adelaide University, Australia. He will construct a number of polarsondes with which he will make validation measurements in mixed phase clouds and fogs at Summit Station, Greenland, comparing the polarsonde against other instruments that can measure the amounts of liquid and ice in a cloud. The PI will collaborate with Dr. Matthew Shupe and Dr. David Noone at the University of Colorado (current NSF grants 0856559 and 1023574, respectively). During July 2012, the PI will travel commercially to Kangerlussuaq, and onward to Summit Station via the ANG. He will spend approximately one week on site evaluating the performance of polarsondes installed on the Summit Station 50-meter tower before departing on an ANG flight and flying homeward by commercial air. The polarsondes on the tower will be left in place for one year. Additionally, the polarsondes will occasionally be launched in conjunction with the ICECAPS radiosonde balloons. The data will be recorded and transmitted back to Adelaide by the collaborators, who will also use the data for their studies of mixed phase clouds and precipitation on the icecap. The PI will return to Summit in July 2013 to test polarsondes that have been modified to remove the shortcomings identified in the 2012 season. The PI will travel commerically to Kangerlussuaq, and onward to Summit Station via the ANG. The polarsondes on the tower will be left in place through winter 2013-2014. The data will be recorded and transmitted back to Adelaide by the collaborators, who will also use the data for their studies of mixed phase clouds and precipitation on the icecap.

CPS will provide Air National Guard (ANG) flight coordination between Kangerlussuaq and Summit Station, Summit user days, and access to infrastructure and science technician support at Summit Station for the year-round experiment. The NSF will recoup support costs directly from the PI's institution. All other costs, including accomodations in Kangerlussuaq, will be paid by the PI.

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.

Logistics Summary:
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.

Project Web Site(s):
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:
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:
For this EAGER grant, the PI will engage in a formal distance-learning activity as a supplementary educational activity to the Integrated Characterization of Energy, Clouds, Atmospheric state, and Precipitation at Summit project (ICECAPS, NSF grant 0856773). The PI will train students at the University of Idaho (home institution of ICECAPS PI, Von Walden) to use off-the-shelf and relatively inexpensive hand-held devices to conduct experiments analogous to those researchers conduct in Greenland, as part of ICECAPS, with far more sophisticated equipment. This project is funded as a pilot, both to see whether the technological capacity exists to carry out the kinds of instruction the PI envisions and to see whether the project can dovetail with and enhance Science in Education Week, an activity involving U.S. students that is part of the Denmark, Greenland, U.S.-supported Joint Science Education Project (JSEP).

Logistics Summary:
The PI leads a pilot education effort, a supplemental component to the ICECAPS atmospheric science project. During a visit to Greenland in July 2012, his team will establish the project. Two people will travel to Greenland via the ANG logistics hub in mid-July. One will base in Kangerlussuaq during the flight period, and the other will spend several days at Summit Station familiarizing with the ICECAPS project. The team will collect information to produce a model of education and outreach for remote STEM research that can be used to meaningfully engage K-12 and public communities; vet learning tools; explore future education and outreach potentialities; and take measurements and interact with student groups online. The team also will work alongside U.S. students participating in the Joint Science Education Project week (labeled “JSEP” in this database) as permissible within the existing curriculum, and in coordination with the teacher leading the experience. The pair will complete this effort and depart Greenland via the ANG at the end of the flight period.

CPS will provide ANG support for passengers and some cargo, KISS user days, Summit user days, and space in the Mobile Science Facility during the Summit stay. The PI will arrange other logistics and pay those costs through the grant.

Science Summary:
This Cooperative Agreement supports the continued management and operation of the UNAVCO Global Positioning System (GPS) and geodetic technology support facility over a five-year period. UNAVCO is a non-profit corporation governed by a Board of Directors elected by the UNAVCO member institutions, which are comprised predominantly of U.S. academic institutions with active research programs in geodesy. There are currently over 100 member institutions. The UNAVCO mission is to advance high-precision techniques for the measurement of crustal deformation. The facility is supported by NSF Division of Earth Sciences, Office of Polar Programs and NASA (through annual agency transfers) for responsibilities including: 1) maintenance of a pool of state-of-the-art GPS equipment available to NSF-supported scientists; 2) provision of personnel dedicated to NSF- and NASA-funded GPS and geodetic technologies project planning, logistics and field engineering support; 3) maintenance of the NASA Global GPS Network (GGN) that provides crucial data to the International Earth Rotation and Reference Systems Service (IERS) needed for International Terrestrial Reference Frame (ITRF) solutions; 4) development and maintenance of a GPS data archive; 5) planning and coordination of various geodetic community activities (e.g., scientific workshops, steering committee meetings); 6) development and evaluation of new commercial GPS technology; 7) ensuring a representative and responsive governance process on behalf of the U.S. academic research community using precision geodetic techniques; and 8) provision of education and outreach to students and the public about precision geodetic research applications, the Earth sciences, and UNAVCO. Funding provides salary support for a staff of over 25 full time scientists, engineers and associated business support staff. Dense GPS observations in space and time have resulted in fundamental new discoveries in the Earth sciences that have had a significant impact on our understanding of the Earth system and the complex interplays between the Earth's interior dynamics, tectonic, magmatic, seismic and surface processes, and the global climate system. UNAVCO makes key contributions to the science and public policy enterprise through facilitating advances in understanding and responding to seismic, volcanic and coastal margin hazards and the effects of climate dynamics on the Earth's cryosphere and hydrosphere.

Logistics Summary:
This grant continues a Cooperative Agreement first operating under grant 0321760 from 2003 to 2008. Via this funding mechanism, UNAVCO provides a variety of GPS support to NSF-funded scientists, including maintenance of GPS base stations in Alaska at Toolik Field Station, and at Barrow on the North Slope. UNAVCO also maintains a base station and differential GPS survey equipment at Summit Station, Greenland. While UNAVCO supports a number of individual research projects per year with customized GPS support, that information is not carried in this record (instead it is carried under the grant receiving the UNAVCO support). This record focuses on work related to these three arctic base stations. In addition to maintaining the base stations, GPS equipment is provided for making field measurements. From January 2008 through 2012, UNAVCO will continue to operate and maintain the GPS base stations. For each year of the grant a UNAVCO researcher will make a one-week site visit to Barrow to calibrate and maintain the installations and to train on-site staff and researchers. UNAVCO will visit Summit Station and Toolik Field Station each year if those base stations require technical intervention/maintenance. One UNAVCO staff member will visit Barrow in August 2011 to meet and train staff. The technician also will travel to Atqasuk to re-evaluate support requirements after the shutdown of the ARM facility. UNAVCO plans no trips to Summit Station in 2011. For 2013-2018 work, see new UNAVCO grant # 1261833.

UMIAQ will maintain the GPS and data processing in Barrow. All equipment scheduling will be done by a designated local UMIAQ staff member. CPS will pay for the travel associated with this training, while UNAVCO covers the cost of training under this grant. The PI will arrange/pay for all other logistics through the grant.

Since its launch the Joint Committee has established an impressive track record of accomplishments that span a range of issues of mutual concern, including culture, education, science, environmental research, technical assistance, and commercial affairs. The Joint Committee meets annually to assess its ongoing work and to evaluate new project proposals. One such Joint Committee activity is Science Education Week. This annual event, first offered in 2007, gives a select group of Greenlandic, Danish and U.S. secondary school students and educators an opportunity to visit and study the Greenland ice sheet during the summer research season. Science education week supports participant visits to several research sites in Greenland; expedition members spend about a week in Greenland learning about the research conducted there and the logistics involved in supporting the research. They also get first-hand experience conducting experiments and developing inquiry-based educational activities.

Logistics Summary:
Starting in 2007, a group of students and teachers from the US, Greenland and Denmark annually will spend a week visiting the Greenland ice sheet on a brief tour of active field sites to better understand the research done there and the complex logistics involved in supporting the work. Each year, a group assembles in Kangerlussuaq, the US participants arriving via Air National Guard (ANG) transport from New York. After an orientation lecture, the group will tour the local science facilities such as the Kellyville observatory and will visit science projects local to the area. As able, the team will assist researchers with their experiments. Later in the week, the visitors will fly via ANG to Summit Station to meet scientists, tour the facilities, and assist on routine science conducted at the station. In 2011-2012, participants will also fly on to NEEM to see the ice core drilling taking place there. On return to Kangerlussuaq, the team may take other tours before debriefing and returning to their home institutes. In late June 2007, a group of about 16 (including media and program escorts) will assemble in Kangerlussuaq. After a tour of research done in the area, the team will fly via ANG to Summit for an overnight stay. In early July 2008, approximately 12 participants will join the tour, headed by Kathy Gorski, Albert Einstein Distinguished Educator Fellow for 2008-2009. In 2009, a trip similar to 2008 is planned. Jennifer Thompson, Albert Einstein Distinguished Educator Fellow 2009-2010, will lead this team. Also in 2009, Glen Schuster (0732793, SPRINTT) will accompany the group to Kangerlussuaq and Summit. Afterwards, Mr. Schuster and Jennifer Thompson will visit educators in Nuuk, Aasait, and Illuisat, Greenland. The logisitcs are covered under 0732793 in this database. In 2012 a student in the IGERT program (Ross Virginia, Dartmouth, PI) will join the Science in Education group to mentor the younger scholars. In 2013, the program kicks off with a two-week field school course in July in Kangerlussuaq led by the Greenland component of the program. After, a subset of students continues in the program to visiting Summit Station led by the U.S component of the program. The group will connect with the IGERT program (Ross Virginia, Dartmouth, PI) at Summit Station to mentor younger scholars. In 2014, the program again kicks off with the two-week Field School course in July in Kangerlussuaq led by the Greenland component of the program. A subset of students then continues in the program with a visit to Summit Station led by the U.S component of the program. A teacher sponsored by the Chilean Antarctic Institute will participate in the entire JSEP program. One member of the IGERT program (NSF grant 0801490, Ross Virginia, Dartmouth, PI) will join the Science Education Week group at Summit Station to help mentor younger scholars. This project's work is continued under NSF grant 1506155. The team will be lead by Albert Einstein Distinguished Educator Fellows as follows: Martha Canipe (2010), Laura Lukes (2011), Shelly Hynes (2012) and Lynne Reed (2013 and 2014).

For the American participants, CPS will provide commercial air tickets between home and Albany, New York, lodging and per diem (the latter by reimbursement) for domestic travel, commercial air and an escort in Copenhagen for 3 U.S. students flying home after the Field School portion of the program, (by reimbursement) travel/evacuation insurance for all participants and Field School user fees. For all participants, CPS will provide clearances for ANG transport, user days at Summit, vehicle rental in Kangerlussuaq, cold-weather gear, an escort during the Science Education week, field, safety, and communications equipment and meal tickets in Kangerlussaq during SciEd. The Chilean teacher will pay for travel between Chile and Albany, New York and CPS will pay all of her other expenses; CPS will pay for one night at KISS for a visiting lecturer for Field School. All other expenses for Greenlandic and Danish students will be paid by the other host organizations.

Science Summary:
This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). This award supports a field campaign that will expand the Arctic Observing Network (AON) by adding cloud, atmosphere, and precipitation measurements, and associated higher-order data products, to Summit, Greenland, at the top of the Greenland Ice Sheet. The proposed instrument suite consists of a cloud radar, two microwave radiometers, an Atmospheric Emitted Radiance Interferometer, an X-band precipitation sensor, a ceilometer, a micropulse lidar, and a twice-daily radiosonde program. Measurements from this advanced suite of instruments, combined with some ongoing measurements at Summit, will be input for a number of algorithms to produce climatically useful geophysical data products to support GIS-specific and Arctic-wide research. Data products will include: (1) Atmospheric State - temperature and moisture profiles through the troposphere and lower stratosphere; (2) Cloud Macrophysics - cloud occurrence, vertical boundaries, and temperatures; (3) Cloud Microphysics - cloud phase, water content, optical depth, and particle size; (4) Precipitation - precipitation type and rate; and (5) Cloud Radiative Forcing - impact of clouds on the surface radiation balance. Together these products will augment similar data sets that are produced at other locations across the Arctic. It is anticipated and intended that these data sets will be widely used by the broader scientific community to understand the climates of the Greenland Ice Sheet and the broader Arctic Basin and to validate satellite retrievals and model simulations over Greenland. The "Broader Impacts" of this award are numerous. The proposed observations will contribute to the goals of the Study of Arctic Environmental Change (SEARCH). They will be the first of their kind on the Greenland Ice Sheet and will expand the existing, although modest, network of such measurements across the Arctic. Uncertainty in polar cloud properties is a major deficiency in current models of polar climate; the proposed observations of cloud macro- and micro-physics will provide some of the necessary constraints for improving model cloud algorithms. This project will provide important field work and data processing experience for graduate students at the University of Wisconsin, University of Colorado and University of Idaho. In addition, data and experiences from the field program will be integrated into undergraduate coursework at the University of Idaho and summer workshops at the University of Wisconsin.

Logistics Summary:
This collaborative project between 0856773 (Walden, U of Idaho), 0904152 (Turner, U of WI), and 0856559 (Shupe, CU) plans an intensive cloud experiment at Summit with fieldwork from late spring 2010 through late spring 2014. A short reconnaissance trip is planned for summer 2009. Logistical details under 0856773.

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:
This project is co-funded between NSF and NASA. In 1995, the PI initiated 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]); and 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 (D

CPS will provide ANG cargo coordination from the U.S., 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. In 2017, two researchers will visit Summit in May 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. The project team plans to install a post hole sensor for a 1-2 year comparison with the current seismic system to investigate potential replacement of the system in future years.

CPS will provide ANG travel and cargo support to/from Summit Station, Summit Station user days, a snow auger/corer with required tools, access to infrastructure, and year around science technician support for re-leveling the instrument, maintaining data and power cables above the snow surface, and general maintenance/troubleshooting 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:
This seismological research aims at understanding the causes of onshore uplift in the North Atlantic region. The research team will acquire new Broad-Band Seismological data over a two year period and carry out the first controlled-source seismic experiment in onshore Greenland. The project will involve integrated interpretation of the new broad-band and controlled-source seismic data from a 300 by 600 km large area in central eastern Greenland. The focus of the planned science involves. 1) Deployment of broad-band seismic stations in the area from the center of the ice cap to the East coast in a 700-km-long transect. The instruments were deployed in June/August 2009; the researchers will visit the locations for inspection and maintenance in 2010 and retrieve the stations in 2011. 2) Data will be acquired by controlled source techniques in 2011. In 2010 we need to test the efficiency of the sources and the drilling operation involved. This is a complementary and integrated part of the experiment already installed. The data will be processed on work stations and a high-performance computer cluster equipped with state-of-the-art software for the data processing and modeling to obtain a detailed image of the crustal and upper mantle structure. This information will be used to constrain geodynamic models of the origin of the observed topography in eastern Greenland. Additionally the broad band seismic data will be used for determination of glacial earthquakes in Greenland.

Logistics Summary:
The PI leads seismological research at the University of Copenhagen to better understand onshore uplift of the North Atlantic region. A six-person research team will use Summit Station as a hub and an entry point to the Greenland ice sheet to carry out a large scale seismic refraction project along a 350 km profile line located 200 km south of Summit Station. (Some or all of these instruments were installed in 2009 by U Copenhagen team led by Trine Dahl-Jensen; see the record in this database for "DJSeismic" in this database). The researchers will drill holes to approximately100-m depth in the ice and charge the holes with explosives. Seismographs will be deployed to register seismic waves originating from the explosions. The instruments will further be recording signals emitted from a seismic vessel in the Scorebysund Fjord. In 2010, after travelling to Summit via the ANG logistics chain, the team will spend ~10 days off-station traversing approximately 400 km away from Summit via snowmachines to service their existing seismic stations. They will camp during this period. Later, the team will return to Summit and, based from there, spend another ~10 days making day trips to conduct drill tests a short distance from Summit. When finished the researchers will depart the station via the ANG, returning to Kangerlussuaq and traveling back to Europe via commercial air. In 2011, late June, the field team will assemble at Summit Station to depart for the study site via snowmachine traverse. Upon completion of the project, the research team will return to Summit Station in mid August via snowmachine. The research team will depart Summit Station with critical cargo via the ANG. Non critical cargo will remain at Summit for retro during 2012, as opportunity allows. Waste and empty drums will be assembled and secured at the remote study site for retro via tractor during 2012. During May/June 2012, a three-person research team will return to Summit Station, which will be used as a hub for traverses to the project transect for instrument retrieval. The retrieval traverses will be conducted in two approximately six-day segments, with rest days prior, between, and following the field retrievals. Additionally, prior to arrival of the field team, Greenland Inland Traverse (GrIT) will travel to the study site and retrieve waste and empty drums that were left in the field at the end of the 2011 field season. All waste and retrieved science items will be organized and prioritized by the research team and removed from Summit Station as ANG flight space allows.

CPS will provide ANG coordination for pax/cargo, KISS user days, Summit Station user days, use of items from CPS/NSF inventory including a Case tractor 480STX, snowmachines, snowmachine fuel, sleds, Arctic Oven tents, and safety equipment. CPS will hire an operator and mechanic to conduct the Case tractor traverse retrieval. Additionally, some existing CPS labor and cargo handling will be provided in support of the project. The NSF will recoup costs of this support via a direct-bill arrangement with the PI's institution. The researchers will pay for all other logistics, including travel to Kangerlussuaq for European participants, with their own resources.

Science Summary:
This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). This award supports a field campaign that will expand the Arctic Observing Network (AON) by adding cloud, atmosphere, and precipitation measurements, and associated higher-order data products, to Summit, Greenland, at the top of the Greenland Ice Sheet. The proposed instrument suite consists of a cloud radar, two microwave radiometers, an Atmospheric Emitted Radiance Interferometer, an X-band precipitation sensor, a ceilometer, a micropulse lidar, and a twice-daily radiosonde program. Measurements from this advanced suite of instruments, combined with some ongoing measurements at Summit, will be input for a number of algorithms to produce climatically useful geophysical data products to support GIS-specific and Arctic-wide research. Data products will include: (1) Atmospheric State - temperature and moisture profiles through the troposphere and lower stratosphere; (2) Cloud Macrophysics - cloud occurrence, vertical boundaries, and temperatures; (3) Cloud Microphysics - cloud phase, water content, optical depth, and particle size; (4) Precipitation - precipitation type and rate; and (5) Cloud Radiative Forcing - impact of clouds on the surface radiation balance. Together these products will augment similar data sets that are produced at other locations across the Arctic. It is anticipated and intended that these data sets will be widely used by the broader scientific community to understand the climates of the Greenland Ice Sheet and the broader Arctic Basin and to validate satellite retrievals and model simulations over Greenland. The "Broader Impacts" of this award are numerous. The proposed observations will contribute to the goals of the Study of Arctic Environmental Change (SEARCH). They will be the first of their kind on the Greenland Ice Sheet and will expand the existing, although modest, network of such measurements across the Arctic. Uncertainty in polar cloud properties is a major deficiency in current models of polar climate; the proposed observations of cloud macro- and micro-physics will provide some of the necessary constraints for improving model cloud algorithms. This project will provide important field work and data processing experience for graduate students at the University of Wisconsin, University of Colorado and University of Idaho. In addition, data and experiences from the field program will be integrated into undergraduate coursework at the University of Idaho and summer workshops at the University of Wisconsin.

Logistics Summary:
This collaborative project between 0856773 (Walden, U of Idaho), 0904152 (Turner, U of WI), and 0856559 (Shupe, CU) plans an intensive cloud experiment at Summit with fieldwork from late spring 2010 through late spring 2014. A short reconnaissance trip is planned for summer 2009. Logistical details under 0856773.

Science Summary:
This Integrative Graduate Education and Research Training (IGERT) award supports the development of an interdisciplinary graduate program in polar sciences and engineering by merging expertise and facilities from Dartmouth College with the U.S. Army Cold Regions Research and Engineering Laboratory and institutions in Greenland. The purpose of this program is to train doctoral students to have an interdisciplinary view of polar systems and to understand the social and ethical implications of their research. Broader impacts include training and research focused on the components of polar systems that respond to and contribute to rapid environmental change, including the cryosphere (glacial ice, snow, and sea ice systems) and the biogeochemical linkages between plants, soils, and animals. The core curriculum includes an Introduction to Polar Systems and a second course on Sustainability Science, Policy and Ethics that will train students to frame research questions that will have relevance to Arctic residents and policy by using perspectives from western science and traditional ecological knowledge. Depending on their research interests, students will be trained during the Greenland Field Seminar in either terrestrial ecosystem or cryosphere dynamics, followed by instruction in the human dimensions of Arctic change in Nuuk, the site of the University of Greenland and the Inuit Circumpolar Council. IGERT students will receive continuing interdisciplinary training through a seminar series and other related events on polar science and policy organized with the Dickey Center Institute of Arctic Studies, a workshop on preparing grant proposals, an annual program evaluation and research symposium, cross-IGERT activities, and opportunities for specialized training at other institutions or field sites. A special effort will be made to engage with Native American students. IGERT is an NSF-wide program intended to meet the challenges of educating U.S. Ph.D. scientists and engineers with the interdisciplinary background, deep knowledge in a chosen discipline, and the technical, professional, and personal skills needed for the career demands of the future. The program is intended to catalyze a cultural change in graduate education by establishing innovative new models for graduate education and training in a fertile environment for collaborative research that transcends traditional disciplinary boundaries.

Logistics Summary:
This grant supports a graduate program with a field course designed to offer students hands-on research opportunities. Beginning in 2010, up to 12 students and instructors will travel to Greenland each year for coursework. In 2009, students will complete core introductory courses during the 2009-10 academic year before taking the Greenland course. Six members will travel to Greenland during summer 2009 for planning purposes and will work on curriculum development with Greenlandic colleagues. They plan to spend a few days in Kangerlussuaq and time in Nuuk to meet with faculty at the University and with researchers at the ICC. During the summers of 2010 through 2014, the field course will be carried out with two distinct parts: a two-to-three-week field study effort based from Kangerlussuaq and Summit; and a two-week exploration of policy issues--specifically the human dimensions of climate change--based from Nuuk. For the field study component, students will be grouped into two disciplines: one will focus on terrestrial studies of soil-plant-animal interactions in tundra ecosystems based from Kangerlussuaq; the other will focus on firn/ice studies based from Summit Station. For each year of field work, IGERT team members may deploy to Kangerlussuaq to begin experiments in advance of the field team's arrival. In addition, IGERT students may engage in additional research activities. In 2013, these activities include early season research activities for one student at Summit and four students at Kangerlussuaq. Additionally, a subset of the main field team will visit Ilulissat in 2013 to study and see the rapidly advancing outlet glacier at Ilulissat, and investigate topics related to ecotourism and its environmental and cultural impacts. The 2014 field season will be broken up into three separate segments. Early season Kanger work will consist of three research students and a PolarTREC teacher, Emily Dodson (1345146ED), in June. The mid-season work will include an eight person team that will split into three different field groups in July. During this period two participants will take a short trip to Nuuk while one participant will visit Summit to overlap with the JSEP group. The late season work based out of Kanger will have two participants from late July to August. In 2015, a team of 6 will return to Kangerlussuaq to continue studies/sampling. Based from the KISS, they will make day trips to or camp at sampling sites.

For all years of the grant, CPS will arrange Air National Guard (ANG) flights to and from Kangerlussuaq, field and communications gear, user days and classroom space at the KISS facility, and Kangerlussuaq vehicle rentals. From 2010 – 2014, CPS will pay for all costs associated with this support; in 2015, the PI will pay for lodging and vehicle rentals. In addition, from 2010 to 2014, CPS will provide commercial airline tickets to/from Nuuk and/or Ilulissat, ANG arrangements to/from Summit, and Summit user days. ANG flights are scheduled in advance; if the timing of flights is not suitable, the PI will be responsible for commercial airline tickets. The research team will make all other arrangements and pay for them via the grant.

Logistics Summary:
Researchers on this collaboration between Walden (0856773, U of Idaho), Turner (0904152, U of WI), and Shupe (0856559, CU) will carry out an intensive cloud experiment at Summit with fieldwork from late spring 2010 through late spring 2013. After installing instruments at Summit and initiating the experiments, the researchers will maintain a technician at the station year-round. This technician will monitor project instruments and complete an intensive balloon launch campaign with the assistance of on-site Summit technicians. During 2009 a field team of two will conduct a short reconnaissance trip. In May 2010, a field team of six will deploy to Summit and install a suite of instruments, to be maintained for the duration of the 2010 summer and the 2010-2011 winter by a dedicated science technician. In addition to the core ICECAPS experiments, a LiDAR and Sodar will be added to complement the existing suite of instruments. During 2011 the field team will visit Summit for routine maintenance and to minimize instrument down time during the annual Mobile Science Facility move. The deployments will be split into three different periods with an early season deployment for one researcher mid-April through early May, a short (~4 day) deployment for two researchers mid/late-May, and another short deployment (~4 days) mid-June. The ICECAPS project will continue to support one year-round science technician, who will follow the same seasonal staffing cylcle as the CPS crew (with exception of the summer ICECAPS technician, who will turn over mid season) and comply with all CPS safety and program requirements. For the 2012 field season, the deployments will be split into two different periods with an early season deployment for two researchers late April and a deployment for one researcher mid/late-May. Additional deployments may be necessary if further instrument maintenance is required. The ICECAPS project will continue to support one year-round science technician. The ICECAPS technicians will continue to follow the same seasonal staffing cycle as the CPS crew (with exception of the summer ICECAPS technician, who will turn over mid-season) and comply with all CPS safety and program requirements. Logistical details will be carried under 0856773. Future work for this project can be found under NSF grant 1414314.

CPS will provide ANG coordination for the field team and cargo; coordination and space for one passenger on winter air charters; in-transit user days in Kangerlussuaq; access to the Summit Station infrastructure and services, including construction support for relocating and maintaining the Mobile Science Facility; helium provision, shipment, and staging; early season and late season liquid nitrogen provision and shipment; and science technical services. The PIs will make all other arrangements and pay for them through the grant. NOTE: Support details are contingent on continued funding for the project. If funding is awarded, the scope of CPS support will be adjusted beginning in August 2013 to include provision of radiosondes, balloons, and parachutes for twice daily launches; and staffing of a project specific year-round science technician to support the project.
