Science Summary:
This activity will continue support for an office that assists the community of scientist that uses an international research site on the summit of the Greenland ice sheet. Over 20 groups from the U.S. and Europe are using the site and others have projects pending. One key to success of this shared facility is to closely coordinate measurements, share facility resources and exchange data of common interest between investigators to make most efficient use of the facility and resources. Since this coordination goes well beyond what individual investigators can efficiently do through one-to-one interactions, NSF has supported a Science Coordination Office (SCO) since 1999 to work with scientists, the logistic contractor and others to plan both near and long term activities that require strong involvement from the science community. This proposal provides for continuation of the SCO, which has three main objectives: Plan and coordinating measurements including sharing of facilities and personnel, data and requests to funding agencies for upgrades and maintenance to facilitate science;working with the logistics contractor and NSF to plan, develop and operate the station to serve a growing international and multidisciplinary community while maintaining scientific integrity of the site during the transition; and carrying out strategic planning, working with international and national agencies who are involved with supporting activities at Summit, facilitating communication between investigators and reporting to funding agencies.

Logistics Summary:
The Summit Science Coordination Office (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. In support of these goals, SCO members will conduct 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 that meet the evolving needs of the science community. In 2007, 2008 and 2009 one member of this SCO grant will travel to Summit, Greenland. In 2010 SCO members will visit Summit as part of other planned deployments. CPS will work closely with the SCO in developing and implementing plans for Summit that meet the evolving needs of the science community.

Science Summary:
A particularly important process in the Arctic surface energy budget is the snow/ice albedo feedback which contributes considerably to polaramplification of global warming (Køltzow et al., 2007). Several recent studies of pollutant transport, in particular black carbon, to the Arctic indicate that the deposition of black carbon on snow/ice surfaces may have a significant effect on the energy balance (Flanner et al., 2007; Law and Stohl, 2007; Quinn et al., 2007a/b). Currently, there are insufficient measurements to evaluate black carbon induced changes on albedo in a quantitative manner and satellite measurements lack the required precision to monitor this effect. This is a fundamental parameter for climate modelling and requires attention. Researchers on this project propose an innovative solution relying upon state-of-the-art technology to acquire an improved assessment of Arctic albedo variability as well as pollutant induced changes of albedo. The UAV platform will measure albedo over a wide range of Arctic terrain providing a valuable time series of baseline variability. Furthermore, utilizing forecast products from the FLEXPART Lagrangian transport model, they will initiate ‘Intensive Observing Periods’ (IOPs) during unique pollutant transport episodes in which it is suspected black carbon will be delivered efficiently to sampling locations. The UAV will be flown ‘operationally’ during two campaigns, each covering approximately six months. The first campaign will take place in Svalbard, Norway with the objective of measuring snow albedo on polythermal glaciers and over sea ice. The second campaign will focus on the dry snow zone of the Greenland Ice Sheet operating out of the Summit Station observatory. The contrast between these two environments will not only provide an excellent opportunity for comparative measurements, but also enables the development of a data product for albedo with broad application to regional Arctic environments. The primary goals of this project are to: a) establish highest quality measurements of Arctic albedo and background variability, b) quantify induced changes of albedo over snow/ice surfaces driven by transport/deposition of pollutants; c) contribute improved albedo measurements to climate modelers to evaluate feedback processes; d) further develop shared expertise between U.S. and Norwegian researchers working with climate data in Svalbard, Norway and throughout the Arctic.

Logistics Summary:
This project involves the use of an unmanned aerial vehicle (UAV) to collect information that improves understanding of arctic albedo variability as well as pollutant-induced changes of albedo. The researchers will use a state-of-the-art UAV as a platform to measure albedo over a variety of Arctic terrain (sea ice, glaciers, ice sheets, etc.) during two campaigns, the first in 2009 in Ny-Alesund, Norway and the second in 2010 at Summit Station, Greenland. For the 2010 work, the project team will deploy the UAV at Summit for the period of mid-May through mid-August. A total of nine people will visit the station during the period, with an average on-site population of about five. They will occupy a Weatherport shelter set up near the taxiway, where the UAV will launch and land. Though the UAV will be flown autonomously, Summit science technical staff will provide support during each flight. Flights will be scheduled throughout the week to optimize timing with favorable weather / wind patterns, and will have increased frequency during unique episodes as forecasted by the research team's transport modeling system. In addition to the UAV flights, the field team will also be conducting ground truthing at sites at various distances from Summit.

For the 2010 Greenland work, CPS will provide ANG support, KISS and Summit user days, access to infrastructure and services at Summit Station, including science technical support and construction labor to set up a Weatherport shelter, as well as use of snowmachines and Nansen sleds. Researchers are providing fuel for the UAV. Costs associated with the support will be billed directly to the PI/institute. The PI will arrange/pay for all other support.

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. In 2017 a field team of two will demobilize a portion of the NOAA project activities including the ozonesonde system and materials, the CATS GC, and the solar radiation suite (contingent on the timing of calibrated radiometers being returned by the Steffen/NASAAWS project). The field team will also recover components of the meteorological suite from the failed 50m tower and re-install met instruments on the TAWO tower which was relocated 80m south TAWO during June 2017. The science technician position provided via inter-agency transfer will be ended on or about 28 August 2017. Researchers may return in 2018, details are TBD.

CPS will coordinate personnel and cargo transport to and from Summit, provide access to Summit Station infrastructure, Summit user days, Kangerlussuaq user days, 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:
Nitrate is one of the major ions found in alpine and polar snow, yet it continues to be one of the least understood chemical components in ice core records. Recent work has shown nitrate isotope ratios to be a powerful tool for the study of nitrate in snow and ice cores. The isotopic composition of nitrate has been shown to contain information about the source of the nitrate (nitrogen oxides) and the oxidation processes that convert nitrogen oxides to nitrate in the atmosphere prior to deposition. Because hydroxyl and peroxy radicals have very different isotopic compositions than ozone, one can now distinguish the impact of the different oxidation processes that produce nitrate in the atmosphere. Seasonal observations of the oxygen isotopic composition of nitrate in snow at Summit, Greenland, cannot be understood in terms of standard, local photochemistry. The most likely causes of the model and observation discrepancy are that the box model lacks transport of nitrate from regions outside of Summit and the influence of halogen chemistry (i.e., BrO) on nitrate. Recent measurements suggest a higher-than-expected presence of BrO in the boundary layer above Summit. The aim of this project is to quantify the influence of bromine chemistry on nitrate production in the spring and summer. The approach includes field and laboratory measurements as well as modeling. During spring and summer field seasons, BrO and multiple gas-phase measurements will be conducted on-site, while isotopic analyses of snow and atmospheric samples will be completed in the laboratory. The oxygen isotopic composition of nitrate in snow and glacial ice holds potential for quantitatively reconstructing paleoatmospheric oxidant concentrations, but it is important to constrain how much this tracer reflects local versus regional or hemispheric scale chemistry. Furthermore, since BrO at Summit most likely originates from a natural source, and this source is affected by changes in climate, the influence of halogen chemistry on nitrogen oxides has important implications for the interpretation of recent and deep ice core records of nitrate.

Logistics Summary:
Researchers on this collaborative project--0909374 (Hastings, Brown U, LEAD), 0908186 (Huey, GA Tech,) and 0908588 (Dibb, UNH)--will study the influence and connection between halogens and nitrogen oxides chemistry at Summit, Greenland. Scientists will conduct two ~6 week field efforts at Summit to collect samples for further study at the home institutions. Logistics details under 0909374.

Science Summary:
Chemical and biological processes occurring within, above, and below snowpacks influence tropospheric ozone. Measurements available to date and simplified modeling studies indicate that the resulting impact on tropospheric O3 is significant, but available measurements and current modeling capabilities are insufficient for a quantitative estimate of its magnitude. It is of particular importance to improve our understanding of snowpack-atmosphere O3 exchanges because of on going and expected future alterations in snow, sea-ice and permafrost extent resulting from climate change, which will alter snowpack O3 impacts in the future. This project provides an integrated approach to address this need, using field measurements to fill key gaps in current knowledge and synthesizing the new and existing data into a chemistry-climate model. The investigators will measure air-snow exchange fluxes of O3 and NOx (NO+NO2) at multiple sites with different snow/land types, each for an extended period to capture effects of changing insolation, snowpack properties and (where applicable) soil temperature and soil NOx emissions. Measurements will include O3 and NOx levels and gradients both within and above the snowpack and eddy-correlation O3 fluxes at two heights above the snowpack; ancillary measurements will characterize atmospheric turbulence, actinic flux, micrometeorological parameters and the snowpack's physical and radiative properties. The team will develop new parameterizations of snowpack processes and incorporate these into single column model (SCM) versions of the global chemistry-climate models ECHAM4 and ECHAM5-MESSy. These parameterizations will be designed to describe the underlying processes and to capture variations among the available and new field measurements, which will be used for model evaluation. The new model system will be used to simulate the impact of air-snow O3 and NOx exchange upon the arctic tropospheric O3 budget.

Logistics Summary:
Researchers on this collaborative project, Doskey (MTU, 0713992, LEAD) and Helmig (CU,0713943), will conduct extensive campaign ozone and nitric oxide measurements from 2008-2011. They will work at three main sites: Summit, Greenland, representing glacial snowpack; Toolik Lake, Alaska, representing snowpack above permafrost soil and snowpack above frozen lakes; and the Michigan Tech Aspen-FACE research site, representing snowpack above biologically active soil (activities at the latter site will not be covered in this database). For the work at Summit, a research team of about 3 will set up their experiment during a 12-week long campaign at the station starting in June 2008. The tasking will include installing a new ozone instrument and a new nitric oxide instrument. The researchers intend to make the experiment operational coincident with POLARCAT (aircraft based pollution studies) flights over Summit, as the researchers will take simultaneous measurements for cross-validation. When the installation is completed, 1-3 researchers will remain on site, the first in a series of occupations as the team rotates through Summit through station closing on August 22, 2008. During this period, the team member will maintain the instruments and conduct intensive measurements. These include eddy correlation flux measurements, vertical gradients of O3 and NOx, and snowpack measurements. As needed, the station’s technical staff will assist the researcher. A subset of the instruments will be operated over the winter period by Summit staff members. The team will return to Summit with this experiment during the spring of 2009 for a second campaign running through the summer. A third study period involving on-site researchers at Summit will begin in April 2010 and end in late July 2010. Then, the team will dismantle the instruments and ship them to Toolik Lake research facility in Alaska. Personnel/support for some Summit Station activities are combined with the PI's NASA grant (see the record for NASAPolarcat in this database). The field team information for both grants will be carried under this record. (Note: the Summit campaign, originally to end in April 2010, was granted an extension by the NSF through July, 2010). In September, 2010, a team of 4 will travel to Toolik Field Station to install the same instruments. A team member will return at 3-week intervals to maintain the instruments and conduct the same suite of experiments as they will have done at Summit. The instruments will be removed in May/June 2012. The team will travel to Michigan's Upper Peinsula for a winter season in 2009-2010. This work is part of IPY activity #213, “Air-Ice Chemical Interactions,” or AICI, and is collaborative with IPY activity #32, POLARCAT (“Polar Study using Aircraft, Remote Sensing, Surface Measurements and Models, of Climate, Chemistry, Aerosols, and Transport “).

For the work in Greenland, CPS will provide ANG coordination (and air charters as needed to access Summit during non-seasonal periods), user days at Kangerlussuaq and Summit, and access to support infrastructure and services at the station, including science technical services. In addition, CPS shipped gases in advance for the summer of 2008 and 2009. Gases leftover from 2009 will be used for the summer of 2010. For the work in Alaska, CPS will provide Toolik user days, provision of a vehicle, construction support to power the PIs' instrument sites and in 2011 only- freight reimbursement. IAB will provide infrastructure support and services at Toolik. The researchers will pay all other costs from the grant.

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.

Science Summary:
Nitrate is one of the major ions found in alpine and polar snow, yet it continues to be one of the least understood chemical components in ice core records. Recent work has shown nitrate isotope ratios to be a powerful tool for the study of nitrate in snow and ice cores. The isotopic composition of nitrate has been shown to contain information about the source of the nitrate (nitrogen oxides) and the oxidation processes that convert nitrogen oxides to nitrate in the atmosphere prior to deposition. Because hydroxyl and peroxy radicals have very different isotopic compositions than ozone, one can now distinguish the impact of the different oxidation processes that produce nitrate in the atmosphere. Seasonal observations of the oxygen isotopic composition of nitrate in snow at Summit, Greenland, cannot be understood in terms of standard, local photochemistry. The most likely causes of the model and observation discrepancy are that the box model lacks transport of nitrate from regions outside of Summit and the influence of halogen chemistry (i.e., BrO) on nitrate. Recent measurements suggest a higher-than-expected presence of BrO in the boundary layer above Summit. The aim of this project is to quantify the influence of bromine chemistry on nitrate production in the spring and summer. The approach includes field and laboratory measurements as well as modeling. During spring and summer field seasons, BrO and multiple gas-phase measurements will be conducted on-site, while isotopic analyses of snow and atmospheric samples will be completed in the laboratory. The oxygen isotopic composition of nitrate in snow and glacial ice holds potential for quantitatively reconstructing paleoatmospheric oxidant concentrations, but it is important to constrain how much this tracer reflects local versus regional or hemispheric scale chemistry. Furthermore, since BrO at Summit most likely originates from a natural source, and this source is affected by changes in climate, the influence of halogen chemistry on nitrogen oxides has important implications for the interpretation of recent and deep ice core records of nitrate.

Logistics Summary:
Researchers on this collaborative project--0909374 (Hastings, Brown U, LEAD), 0908186 (Huey, GA Tech,) and 0908588 (Dibb, UNH)--will study the influence and connection between halogens and nitrogen oxides chemistry at Summit, Greenland. Scientists will conduct two ~6 week field efforts at Summit to collect samples for further study at the home institutions. In mid May 2010, five researchers will travel to Summit, Greenland, to begin a ~six week period of field work for the project. They will work in a satellite camp established in the Clean Air Sector, travelling to and from the camp on foot or via electric vehicle when possible. The team will take measurements of the atmosphere above the snowpack and collect snowpack samples for analysis of the isotopic composition of nitrate. After about three weeks, two additional team members will arrive. By the end of a ~five-day turnover period, three of the original members will have departed, and the experiment will continue for another ~two weeks, with one additional personnel change. The team will depart Summit in late June and subsequently return to the U.S. During May/June 2011 the researchers will return to Summit to conduct a similar six-week campaign. Five to six people will be on-site at any one time, with a turnover period in early June when the researcher population will rotate. The team will again work at Sat Camp, travelling to and from the camp on foot or via electric vehicle. Measurements and sampling will be similar to those conducted during 2010. Snow samples collected at Summit will be packed into ISC boxes and prepared for shipment by the researchers. While at Summit it will be the researchers’ responsibility to ensure that the samples remain at the proper temperature. At the end of the campaign, samples will be flown from Summit to Kangerlussuaq, where they will be stored in a freezer facility before being flown to Stratton Air Base in New York. The PI will make arrangements for the samples to be retrieved in NY (meeting the plane on the flight day) and shipped onward to the home institutions.

CPS will provide ANG coordination for pax and cargo, in-transit user days in Kangerlussuaq, access to the Summit infrastructure, gases, one ISC box, Johnny Blue Ice, and deployment of Sat Camp structures to the Clean Air Secotr. The PIs will make all other arrangements and pay for them through the grant.

Science Summary:
The Greenland Ice Sheet is an important indicator of the response of the cryosphere to climate and, since the ice sheet contains enough water to raise sea level by 7 meters if it were all to melt, understanding the state of the ice sheet is critically important to scientists, policy-makers and society at large. This award supports an investigation of the physical properties and state of snow and firn along a traverse from Thule, north coastal Greenland, to the summit of the ice sheet. Using techniques planned by the scientists, measurements will be made during resupply traverse in 2011 from Thule Air Base to Summit Station, making detailed observations en route of grain size, density and stratigraphy in 1 m deep snow pits and 10 m deep boreholes in firn. The route will cross through several facies of the ice sheet: ablation zone, soaked snow zone, percolation zone, and the dry-snow interior. The field team will measure snow grain size, density and stratigraphy from 1-m snow pits and 10-m augered boreholes using a suite of traditional methods (visual stratigraphy, visual grain size determination, density from measured mass and known volume) coupled with modern methods based on the radiative transfer properties of snow (ground-penetrating-radar profiling, Borehole Optical Stratigraphy, and near infrared imaging of snowpit walls). Two shallow ice cores obtained at the beginning and end of the traverse, and snow samples, will be returned to the laboratory for examination of microstructure using micro-computed tomography and brightness temperature using optical and near-infra-red photography. The microstructure results will be used as input to a radiative transfer model and the brightness temperature will be used for validation of the simulations. The study has a variety of 'Broader Impacts.' The traverse lies very close to traverses made during 1952-55 when studies of snow and firn properties established the concept of glacier facies; a comparison of the historic results with those of this study will provide valuable insights into changes that have occurred in this region since the mid-1950s. The characterization of the spatial variability of the physical properties of surface and near-surface snow also has application to the interpretation of remote sensing data, which are essential to mapping surface melting across the entire ice sheet. The study will involve a graduate student participant in the Dartmouth College Integrated Graduate Education and Research Traineeship (IGERT) program - 'Polar Environmental Change' - and develop a series of snow-science-themed activities designed for a four-week after-school program for grades 3 and 4 at the Montshire Museum of Science. Dartmouth students trained by museum staff will run the activities.

Logistics Summary:
The PIs will study the physical properties of near-surface snow in northern Greenland in a sampling transect between Thule Air Base, and Summit Greenland, using a resupply traverse as a logistics platform. As part of this work, the team will drill a 30m core near Thule Air Base, a 100m core near Summit Station, and they will also train CRREL participant, Jim Lever, traveling on the Greenland Inland Traverse to conduct en-route sampling between Thule and Summit. In 2010, a team of three will travel to Summit and take a 100m core, log the borehole, and dig a 1-2 meter snow pit for measurements. The cores will be returned to the US and analyzed at the researchers' institute. Additionally, if there is time available during the 2010 field deployment, they will also perform additional tasking including, 1) a dense grid re-survey and GPS work for the ICESAT line, 2) a ground-based LiDAR experiment, and 3) a snowmobile trip to the former GRIP site to complete casing work for Danish colleagues. During 2010, one of the researchers will travel with the traverse from NEEM to Summit. The researcher will serve to replace one of the traverse crew and will continue with sample collection en route. Ice core samples collected at Summit will be packed into ISC boxes and prepared for shipment by the researchers (CPS will supply ISC boxes and eutectics). While at Summit it will be the researchers’ responsibility to ensure that the samples remain at the proper temperature. At the end of the campaign, samples will be flown from Summit to Kangerlussuaq, where they will be stored in a freezer facility before being flown to Stratton Air Base in New York. The CPS team will make arrangements for the samples to be retrieved in NY for shipment onward to the home institutions. Research in 2011 calls for a double deployment. In April, a team of two (and a mountaineer) will travel with GrIT from Thule to NEEM and on to a site ~100 km NW of Summit. The trio will leapfrog with the GrIT, drilling/logging boreholes and digging/sampling snow pits along the way. At the site NW of Summit, the team will camp for one week and conduct a NASA-supported GPS grid. They will drive to Summit to pick up a radar and return to camp. If they complete their work ahead of schedule, they will ski-doo to Summit, where they will be welcomed for a dinner, shower, camping, and to join with the GrIT. (Meanwhile after dropping the team off, GrIT will continue to Summit and stay ~1 week.) If the team doesn’t finish early, the GrIT will pick them up on the way back to Thule. En route, the team (plus their mountaineer) will leapfrog with the GrIT, again collecting samples. The team will spend ~1 week in Thule to re-group after arriving. In July 2011, a team of four will return to Thule and drill two 30m holes at Camp Century. This portion of the project will be captured in an updated Season Plan. The team plans to helicopter to the study site and camp for one week. Samples will be processed at the study site, where the team can cut the ice core into 10cm chunks, scrape and pour into vials in field.

CPS will provide AMC/ANG coordination, lodging in Kangerlussuaq/Thule, user days at Summit, camping gear for the Thule drilling effort, air charters to access the Thule site, core boxes and eutectics, and core storage/retrograde. IDDO will provide the drills. All other logistics will be covered by the researcher from the grant.

Science Summary:
Although it is a remote region, the Arctic is impacted by boreal biomass-burning and anthropogenic emissions that significantly alter tropospheric composition, affecting levels of ozone and ozone precursors and causing radiative and air quality impacts. These impacts have large seasonal and interannual variability and are expected to respond to climate change, as a result of dependencies on boreal wildfire emissions and the state of the North Atlantic Oscillation. To quantify these impacts, information on the ozone-precursor families nitrogen oxides and non-methane hydrocarbons (NMHC) is needed. However, continuous in-situ high-altitude measurements are required for this purpose and are not available at any Arctic station. We propose to make continuous year-round measurements of total reactive nitrogen oxides, PAN, NOx, and NMHC at the high-altitude (3208 m) GEO-Summit Station in Greenland, for a period of 2 years. These measurements will be analyzed in conjunction with FLEXPART transport modeling and simultaneous observations of CO, ozone, and black carbon to identify sources and impacts of both anthropogenic and biomass-burning emissions, with a focus on impacts on arctic tropospheric ozone, ozone precursors, and OH levels and consideration of potential feedbacks upon snowpack photochemistry. This proposal responds to the ROSES-2006 A.16 (International Polar Year) solicitation for individual US investigator participation in multinational field activities carried out as part of IPY. The proposed research is part of the multinational IPY POLARCAT study. Integration with POLARCAT will make available FLEXPART and other modeling and satellite products that will increase the value of the proposed measurements, and the Summit observations will provide seasonal and interannual context for intensive measurements associated with POLARCAT. The results will contribute to multiple NASA strategic science goals involving understanding and predicting current and future atmospheric composition as it relates to climate forcing and air quality.

Logistics Summary:
For this NASA project, the investigators will make continuous year-round measurements of a suite of nitrogen oxides and nonmethane hydrocarbons (NMHC) at Summit Station, Greenland, and then will analyze them in conjunction with transport simulations and simultaneous observations of carbon monoxide, ozone, selected chlorofluorocarbons (CFCs) and black carbon particles. A research team of ~3 will install project instruments during an ~ 3-week stay in early summer, 2008, in time to coordinate project measurements with overflights by the IPY POLARCAT project airplane. The experiment will be operated continuously from June of 2008 until August of 2010. The research team will return to Summit for at least 3 weeks during 2009; on-station science technical staff will run the experiment in their absence. The team will return for 3-5 weeks during the summer of 2010 to finish the experiment and remove the instruments. Some field activities, including logistics for participant travel, for this project may be combined with the PI's NSF grant (see the record for 0713992 in this database). This project is part of IPY activity #32, POLARCAT, and is funded through NASA ROSES 2006 NRA.

CPS support includes ANG coordination of cargo/personnel, provision of Kangerlussuaq user days, access to the Summit infrastructure and services (including ~4 hours weekly of science technical support), and procurement of compressed gasses. CPS shipped gases in advance for the summer of 2008 and 2009. Gases leftover from 2009 will be used for the summer of 2010. NSF will recoup the cost of CPS support via an interagency funds transfer.

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:
This project is comprised of snow sampling and analysis to contribute to better understanding of ice core isotope records by studying isotope diffusion. The climate history reconstruction, using the "precipitation archives" of the ice caps on Greenland and Antarctica, and smaller ice caps elsewhere, relies to a large extent on the hydrogen and oxygen isotope signals. This is true for all time scales, from the long-term glacial-interglacial sequences down to the seasonal cycle. All three stable isotopes of water (2H, 17O and 18O) show a significant seasonal cycle, most pronounced in polar areas. After deposition, however, the amplitude of these seasonal cycles dampens over the years as the consequence of isotope diffusion in the firn phase. During the firn phase diffusion takes place quite efficiently by water vapor transport through the micro channels in the firn. As soon as the firn turns into ice, however, diffusion only takes place within the ice, and is then orders of magnitude slower. Thus, effectively, the firn diffusion pattern gets "frozen" in the ice. Better knowledge of the isotope diffusion process has become even more important. This project will perform a first "real life" firn diffusion experiment in the field, by layer of isotopically labeled snow at "S10" in Greenland, 150 km east of Kangerlussuaq, at Summit Station, Greenland and at a site in Antarctica. In that way they will be able to compare the isotope diffusion process on three sites, widely different in temperature and precipitation amount. The likely influence of mankind on climate is a subject of top political and societal relevance. The paleo-climate information brought about by ice core isotope analysis is very detailed, and thus provides researchers with stringent validation material for models describing the climate system. The work of this project will contribute to the better understanding of ice core isotope records, which in the end leads to better climate models, and thus to more realistic and reliable future climate predictions.

Logistics Summary:
For this isotope study funded by the Netherlands Arctic Program (NAP) of the Netherlands Organization for Scientific Research (NWO), researchers will conduct shallow ice-core sampling in Greenland. From 2007-2011, project researchers will work each year at two sites in Greenland: Summit Station and site “S10” about 150 km east of Kangerlussuaq. At the latter, researchers laid down an isotopically enriched snow layer in 2005; with this project, they will continue studying the layer. They will establish an enriched layer at Summit (and at a third site in Antarctica) for comparative analyses. This database record focuses on the work at Summit Station. The development of the isotope-labelled layer will give experimental validation to isotope diffusion models that are in use to correct ice core measurements. This resampling activity will be an annual event. In August of 2007, 2 researchers will spend several days at Summit Station where they will produce a ~6 x 6 meter isotopically enriched labeled layer in undisturbed snow using a snow maker that draws enriched water from a small inflatable swimming pool. The researchers will also travel via helicopter to the S10 site, 150 km east of Kangerlussuaq, to revisit the experiment they set up in 2005. In July of 2008, a team of two will return to the site at Summit Station where they will obtain samples from 3 snow pits inside their field. They will spend about 2 days at Summit. In 2009, researchers will return to the same study area at Summit Station. Rather than using a snow pit, they will obtain samples using a shallow depth hand corer. They will spend about 3 days at Summit for this work. In August of 2010, the researchers will again collect samples at Summit using a shallow depth manual corer. They will spend approximately two days at Summit Station for this work. In August of 2011, the final year of the project at Summit Station, the researches will again collect samples at Summit Station using a shallow depth manual corer.

CPS will support this project with transport to and from Summit Station of personnel and cargo, KISS user days, Summit user days, and access to the Summit infrastructure and science technical services. CPS will recoup costs associated with this support via a direct-bill arrangement. All other expenses will be arranged by the PI and paid with grant funds

Science Summary:
The Keweenaw Research Center (KRC) of Michigan Tech University (MTU) annually hosts the Society of Automotive Engineers (SAE) Clean Snowmobile Challenge (CSC) event on its 500-acre test track in Houghton, Michigan. The objectives of the competition are to train students in technology development and to develop transportation vehicles with reduced impact on the environment. Over the course of several days of trials, student teams are judged on the design, manufacturing price, presentation, vehicle capabilities such as range, weight, handling acceleration, and cold start, and noise of their vehicles. In the internal compression (IC) engine vehicle class, gaseous emissions are also measured and compared to 2012 EPA standard for HC, CO, and NOx. This grant provides funds to encourage Universities to participate by reimbursing travel expenses and other costs associated for teams entering vehicles in the zero-emissions (ZE) category of the competition. In addition to direct support for the competition, one team per year of the grant may be invited to Summit Station, Greenland, to field-test its snowmobile. In addition to practical experience, the opportunity exposes students and the public to arctic research funded by the National Science Foundation.

Logistics Summary:
This project supports three years of participation in the zero-emissions category in the Clean Snowmobile Challenge (CSC). In addition, each year of the grant, one team 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 2008, 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 will 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. The grant will cover reimbursement of travel expenses and other costs associated for teams entering vehicles in the zero-emissions (ZE) category of the competition in Michigan.

If a team member is invited to Summit Station, CPS will provide shipping for the snowmachine, ANG travel to/from Summit, and user days at Summit and Kangerlussuaq. The PI will arrange and pay for all other logistics 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.

Science Summary:
CryoSat is a European Space Agency-sponsored radar altimetry mission, scheduled for launch in 2004, to determine variations in the thickness of the Earth’s continental ice sheets and marine ice cover. Its primary objective is to test the prediction of thinning arctic ice due to global warming. The ice on land and floating in the oceans of the Arctic and Antarctic has a central role in the global climate. Although thousands of kilometres away from most populated regions, the ice can determine the climate for example in Europe, Asia and America by influencing the circulation of water in the oceans. The Arctic is the region on Earth where the greatest changes due to global warming are predicted. If Arctic sea ice becomes thinner over the next few decades, as some observations indicate, it could change the circulation pattern of the north Atlantic, changing the supply of heat to western Europe. The sources for the observed rise in global sea level are not well documented. Are the Greenland and Antarctic ice sheets melting and therefore contributing to the world-wide rise in sea level? As yet this question cannot be answered. CryoSat will help to find answers to these questions and contribute to scientific studies of the polar climate, the sea ice and the ice sheets with a level of detail that is not possible today. Determining the uncertainty in CryoSat products requires a wide range of surface measurements of ice character, geometry and distribution, and the change of these properties with time. These uncertainties may be correlated over considerable time scales. In principal, this may be achieved by examining the difference between the CryoSat data product and a suitably large number of independent, accurate measurements. Campaigns are required which help to reduce the number of independent estimates of errors to a necessary minimum that, on the basis of some physical argument, may be extrapolated to the satellite data as a whole. Following ESA's Announcement of Opportunity for CryoSat Calibration and Validation proposals issued in 2001, a team of scientists comprising 18 different projects were selected to form the CryoSat Calibration, Validation and Retrieval team. This team is responsible for formulating the strategy for calibrating and validating CryoSat. In August 2003, the draft version of the CryoSat Validation Implementation Plan was released. This document, which provides a comprehensive plan for campaign activities between 2003 and 2006, calls for a set of key experiments to be carried out on the ground, from ships and from airborne platforms in order to fully validate the scientific data from CryoSat.

Logistics Summary:
For this portion of the Cryosat Calibration/Validation project, researchers from the UK will take a number of measurements along the International Glaciological Expedition Greenland (EGIG) line that crosses central Greenland. In both 2004 and 2006 a team of 4 from University of Glasgow AKA "UK2" plan to spend about a month visiting sites in the west using site T0005 (69.83 N -47.27 E) as a base. A 2-person "UK1" team from Scott Polar Research Institute plans a 400km traverse between T0012 and Summit, conducting snow density measurements via the neutron scattering technique. The UK1 researchers will establish caches at locations T0021 and T0041 to aid them in their traverse. In 2008, a two-person party will travel by commercial air to Kangerlussuaq in mid-April. They will travel on to Qaanaq via Twin Otter, and from there, put in via Twin Otter to their traverse starting point on the north-west part of the ice sheet at approximately 79 N 50 W. The pair will then travel via snowmachine along the 2100 m contour to approximately 77 52 N 57 W and thence to the NEEM drilling site (77 30 N 51 W). From NEEM, they will return to Kangerlussuaq via LC-130 early in June. For 2010, a team of two will travel to Kangerlussuaq via commercial air from England in late May. After spending about a week at the hub preparing for the traverse, the pair will fly into Summit with the ANG in early June. From there, they will launch a skidoo traverse. The team will depart Summit and traverse to the southwest, taking snow-density measurements en route, and then will return to Summit. They will resupply fuel and other supplies via caches established previously. When they've finished the work, the two researchers will fly back to Kangerlussuaq and depart Greenland from there. The 2011 effort is organized in two phases, each of which involves a snow machine traverse accomplished by two pairs of researchers. In spring, a team of two, dubbed “UK1,” will fly to Summit Station from Kangerlussuaq via ANG around April 20, from whence they will launch the traverse several days later. This team will travel to T21, collecting snow density measurements along the way. About 2.5 weeks later, the second team of two, dubbed “UK2,” will meet the traverse at T21 during a series of Twin Otter resupply, personnel change-out, and depot-laying flights. UK2 will then ride toward Summit Station using the traverse infrastructure used by UK1. UK 1 will return to Kangerlussuaq and fly home via commercial air. (A fifth team member will deploy to Kangerlussuaq to assist with the Twin Otter resupply/personnel change out activities; he will spend about 3 days in Kangerlussuaq before departing Greenland). After they arrive at Summit Station via the traverse, UK2 will store the project’s gear and depart Summit Station, returning via commercial air to their homes. UK 1 will return in July to Summit via ANG, and then spend around 10 days traversing to T21 via T41. Meanwhile, UK2 will fly via Twin Otter from Kangerlussuaq to T21, working locally along the EGIG line. When UK1 arrives at T21, the four researchers will spend a few days working at the site before UK1 returns to Summit (and then to Kangerlussuaq via ANG for onward commercial travel); UK2 will be taken out of the field and returned to Kangerlussuaq via Twin Otter flights that are also laying depots at T21. No fieldwork will be conducted in 2012 -2014.

In 2004, KMS will provide Twin Otter support and snowmachines, while VPR will provide communications gear and support at Summit, in addition to cost-reimbursable fuel and cargo transport. In 2006 CPS will provide cost reimbursable air support, snowmachines, fuel, and cargo transport. In 2008, DNSC (Forsberg) will provide most of the logistics support. CPS will provide cargo transport by C-130 from Kangerlussuaq to Thule; fuels (Mogas, Coleman fuel, skidoo oil); packing space and assistance while the team transits Kangerlussuaq and Thule; Iridium phone and daily safety check-ins; two new snowmachines; and C-130 transport from NEEM to Kangerlussuaq. Support will be provided on a billable basis. In 2010 and 2011, CPS will provide ANG flight coordination for passengers and cargo, Summit user days, some fuel(s), safety/communications gear, Air Greenland and Norlandair flight coordination for fuel depots, and Kangerlussuaq and Summit staff assistance. This support will be provided on a billable basis.

Science Summary:
This proposal continues and expands the PolarTREC program that matches K-12 educators with researchers for field experiences in the Arctic and Antarctic. Annually the project will select 6-8 Arctic and 4-6 Antarctic projects to host teachers selected from nationwide applicants. Over four years, 48 teachers will go to the polar regions. The project has four objectives to: improve teacher content knowledge of multidisciplinary polar science; improve teacher instructional practices, especially the use of inquiry-based learning to translate polar science to the classroom; improve polar researchers? understanding of and engagement in K-12 education; and increase students? understanding of and engagement in the polar regions and polar science, technology, engineering, or mathematics (STEM) careers. The teacher experience includes an intense orientation focusing on having a successful field experience and translating that into the classroom, developing an education and outreach plan that focuses on their specific needs and goals, a final essay, submitting journals and photos to a website of real-time materials plus occasional live broadcasts from the field, follow up through a share fare to exchange activities and a network of teachers sharing ideas for incorporating the experience into their classrooms all backed up by external evaluation of the project using formative and summative techniques to address teacher professional development.

Science Summary:
The US-Denmark-Greenland Joint Committee was established in 2004 to broaden and deepen cooperation among the United States, the Kingdom of Denmark, and Greenland. 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:
Recent advances in climate modeling science have shown that the Arctic is particularly vulnerable to the effects of climate change. The snow and ice that cover the polar ice cap and Greenland play a key role in the future environmental development of the Arctic and also the boreal zone of which Finland is also part. Of particular importance are those properties of arctic snow and ice that govern the absorption and reflection of solar radiation. While several studies have been made concerning the radiative properties of snow and ice and their correlation to electro-optical satellite observations, a comprehensive understanding of the interconnections between the radiative and physical properties of snow is still lacking. The correlations in behavior of snow when observed in the optical, microwave or the physical properties domain need to be understood if the Earth Observation community is to provide precision data on the Arctic to the climate modelers. The annual melting and refreezing of the Arctic is controlled by its radiation budget. This radiation budget depends greatly on the albedo, or brightness, of snow. The albedo of snow depends on its physical properties such as grain size, age and water content. The aim of the Radiation, Snow Characteristics and Albedo at Summit (RASCALS) campaign is to study the arctic snow in a comprehensive manner in a pristine environment, linking physical properties with reflective properties in both optical and microwave wavelengths. The researchers will use at least ENVISAT ASAR observations as the microwave data source. The expected end results are algorithms to accurately link the albedo, angular reflectance functions, and microwave backscatter signatures with the physical properties of snow. These algorithms may then be employed to significantly increase the accuracy to satellite-based snow property retrievals, which will again lead to significant increases in climate modeling accuracy in the Arctic. The researchers will field this campaign at Summit Station, Greenland.

Logistics Summary:
Researchers with this Finnish Meteorological Institute (FMI) project will study links between physical, optical and microwave snow properties. During a three-week campaign at Summit Station in 2010, the researchers will deploy albedo-, spectro- and gonio-meters around Summit to capture the BRDF, spectral snow signatures and the overall broadband albedo. They will combine this data with on-site snow physical property measurements such as grain size and water content to improve the optical satellite estimates of surface albedo. A team of three will travel via commercial air to Kangerlussuaq and on to Summit via ANG in June, 2010. They will base from Summit and sample daily at various sites around station, each site requiring a clear-sky view away from human infrastructure. Some sampling sites will be “fixed” and sampled repeatedly during the day, and 4-6 roving sites/day will be sampled only once; selection of these sites (TBD) will be coordinated with CPS staff and the Summit Science coordination office. If a low-emissions snowmachine is available, the team also will make one or two 20-40km transects for spatial snow heterogeneity studies and for ground-truthing satellite information. At the end of the campaign, the team will remove all instruments and equipment and fly via ANG back to Kangerlussuaq, returning to their home institute from there via commercial air.

CPS will provide Kangerlussuaq and Summit user days, Air National Guard (ANG) transport coordination for personnel and gear from Kangerlussuaq to Summit and return, and fuel. (Summit user days include access to infrastructure and services as needed, including potential use of a low-emissions snow machine should one be available). These costs will be recouped for the Arctic Research Program via a direct bill agreement between CPS and the Finnish Meteorological Institute. The PIs will arrange all other logistics and pay for them 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 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:
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 award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). The Greenland Ice Sheet (GIS) plays a major role in Arctic climate and is a major consideration in projections of sea level rise. Diagnosing the surface mass balance of the GIS is a critical objective that continues to involve large uncertainties from errors in modeled precipitation and errors related to sub-grid-scale process representation. To date, there has been limited work in integrating remote sensing techniques and ground-based data with modeling. In this project, a data assimilation approach will provide a rigorous framework for merging these disparate sources of information in a consistent way (based on their associated uncertainty) to obtain an optimal surface mass balance posterior estimate comprising maps in space and time. This project will focus on implementing a synergistic modeling/observation framework with the final outcome being improved estimates of the mean and uncertainty of the surface states and fluxes associated with the surface mass balance. Broader impacts include a significant contribution to understanding of GIS influence on sea level rise.

Logistics Summary:
This project will advance the ability to map, quantify, and assess the surface mass balance (SMB) of the Greenland Ice Sheet (GIS). Field work in 2010 involves visits to Summit Station and to Ilulissat. First, in late June, a team of three will travel via Air National Guard to Kangerlussuaq and on to Summit Station. They will spend about six days there digging and testing a series of snow pits, including a large (~4 m depth) pit, for which Summit equipment operations staff will use heavy equipment to complete the initial digging effort. When this work is finished, the team will return via ANG to Kangerlussuaq; one will depart Greenland and two will travel on via commercial air to Ilulissat for the second part of the work. In Ilulissat, the two will rendezvous with an additional colleague for a ~10-day research effort. They will fly via helicopter to the area of interest, melt lakes near Swiss Camp. They will establish a tent camp at one of the lakes and conduct measurements, including specific surface area observations with near infra-red photography. The duration of this effort will be about a week. When they have finished the work, the team will pull out of the field and return to Ilulissat. From there, they will depart the island via commercial air. CPS staff in Ilulissat will forward shipments from camp including frozen samples and team cargo to Kanger and then the US. Field work in 2011 involves a return visit to the ice cap via Ilulissat. In early June, a team of four will travel via Air National Guard to Kangerlussuaq and on to Ilulissat via commercial air. The team will spend a day preparing and will then be put-in via Bell 212 at a camp about 70 mi. from Ilulissat for a ~10-day research effort. After establishing their tent camp the team will traverse on foot to several sites of interest in the area, conducting measurements and installing GPS units. When they have finished the work, the team will pull out of the field and return to Ilulissat. From there, they will fly commercial air to Kangerlussuaq and then depart Greenland via the Air National Guard.

With funding from an interagency transfer from NASA to NSF, CPS will provide ANG transport to/from Scotia and Kanger for people and cargo, en route user days in Kangerlussuaq, en route travel/freight to/from Ilulissat and lodging and truck rental in Ilulissat, air travel to/from the field camp and camping/safety gear. The PI will arrange all other support and pay for it through the grant.

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.
