Science Summary:
An important issue of our time involves questions of how human activity has been impacted by the atmospheric composition of our planet. A major area as part of the International Polar Year (IPY) involves developing a better understanding of past climates and the impact of anthropogenic activity on the Earth's atmosphere. Because instrumental records of atmospheric chemistry are limited, natural archives of atmospheric composition must be made, such as polar firn. Its porous nature, tens of meters in depth, permits interstitial diffusion of gases over time with the oldest air at the bottom of the firn column which allows the sampling of large quantities of pre-industrial air to explore anthropogenic effects on the atmosphere. This project will investigate the underlying physics controlling firn's ability to store atmospheric samples from the past. The Principal Investigators will make high-resolution measurements of the diffusivity profile, permeability profile, and accompanying microstructure at Summit from the surface to pore close-off, and compare the results to the diffusivity profile inferred from measurements of firn air chemical composition. They will partner with Dr. Atsumu Ohmura, Swiss Federal Institute, and Dr. Christophe Ferrari of LGGE, France. This project has four goals: 1) Quantify the dependence of interstitial transport processes on firn microstructure, and determine the dependence of gas diffusivity on microstructure characteristics from the surface down to the pore close-off depth; 2) Quantify post-depositional changes in the physical properties of snow and firn and use measured properties of firn and meteorological data to evaluate and develop models of the physical transport processes which drive firnification where temperature gradients are large. 3) Conduct firn air chemical measurements as the firn characteristics are determined, and compare the co-registered diffusivity profile inferred from the firn air chemistry measurements to the high-resolution tracer gas measurements made on the firn core itself. 4) Use the measurements of firn air composition and firn structure to better quantify the differences between atmospheric composition (present and past), and the air trapped in both the firn, and in air bubbles within ice. Broader Impacts: This study will establish quantitative relationships that will enable a better understanding of the firn as a repository of past atmospheric composition, but will also enable us to understand mechanisms that may impact firn air composition at other sites. Results of the research will be published in journal articles and made widely available. This project will form one part of the PhD dissertation of a student from Dartmouth. Several undergraduates will be involved. They will interact with students from Switzerland and France to design and construct an IPY museum exhibit, at the Montshire Museum of Science in Norwich, Vermont. The exhibit will be interactive and will illustrate the ability of snow and firn to serve as an archive of important events of the past. It will allow the viewer to act as the "detective" to track down the meaning of different chemical composition profiles in the firn air.

Logistics Summary:
For this collaborative study of firn air and structure -- 0520445 (Albert, CRREL LEAD), 0520564 (Severinghaus, Scripps) and 0520460 (Battle, Bowdoin) -- investigators will conduct field work at Summit Station, Greenland. Beginning in 2006 a field team of up to 6 researchers and Ice Coring and Drilling Services (ICDS) personnel will travel to Summit, Greenland, for a 6-week field season. In year 1 the team will collaborate with the French team led by Cristophe Ferrari, and with the support of ICDS, will drill firn cores for gas sampling. The cores will be shipped to CRREL for later physical measurements. During all three years of the grant, the team will collaborate with the Swiss team lead by Atsumu Ohmura to conduct near-surface studies to measure the changes of the physical characteristics of surface snow and firn over time. The team collected the firn core and gas samples as planned in 2006, but shipment inefficiencies compromised the material. As a result, the researchers will drill another firn core in 2007 and repeat the firn air sampling, which will increase the scope of their plans for that year. PolarTREC teacher Jo Dodds (0632401JD) will join the field team for their work during that season. In 2008, the team will return to Summit for surface measurements. Approximately 5 people will spend 2-3 weeks retrieving and measuring snow metamorphism in the top meters of firn, both in snow pits and using a hand auger, and comparing the measurements to radar & radiometer measurements. ICDS will not drill this year, though they will provide a hand auger, shipped separately to Scotia. The team will conduct the permeability, thermal conductivity, and other measurements in two cold rooms (covered pits) near the stake forest, in the same pit in which they have been measuring properties other years. Approximately 5 ice core boxes of firn samples will be sent back to CRREL for analysis. Tom Neumann (UVM) will join the field team to conduct comparison radar measurements. These measurements are experimental, pulled by a snowmobile, and can be done in any undisturbed snow area. Neumann will pull the radar in a grid pattern ~ 1km x .5 km. The radar targets will be the Steffen AWS and drill areas from the 2007 campaign.

CPS will support the project via ANG arrangements, user days in Greenland, access to Summit infrastructure, establishment of two plywood covered pits or other cold-room measurement sites at Summit, and will arrange transport of the core from Summit to CRREL in Hanover, NH, and of the ice samples to Scripps Institute of Oceanography in La Jolla, California (2007). ICDS will provide drill support in drilling years. All other logistics will be handled by the investigators from the grant.

Science Summary:
This project involves long-term core measurements of the Arctic atmosphere, snow and other Earth system components at the Summit Greenland Environmental Observatory (GEOSummit). GEOSummit was the site of the GISP2 ice core, completed in 1993, and has been a site of atmospheric, snow and other geophysical measurements ever since. It is currently the only high-altitude site for atmospheric and related measurements in the Arctic. As global atmospheric temperatures rise, the Arctic environment is expected to undergo more rapid change in response to human influences than are other parts of the Earth system, in part due to feedbacks related to decreasing snowcover and sea-ice extent. Observed changes in Arctic temperature, atmospheric chemistry and atmospheric circulation are expected to have potentially broad but uncertain effects on Arctic systems. A number of processes that could amplify atmospheric change need consistent measurements and systematic study. For example, recent evidence indicates that important atmospheric chemical constituents undergo temperature-dependent exchange with ice/snow, and that some species are photochemically transformed and/or produced within the sunlit surface snowpack. Because changes in Arctic atmospheric circulation are cyclic over 4-5 year or longer times, long-duration measurements are needed to understand circulation and to place observed changes in a long-term perspective. The project involves continuing and expanding the core suite of baseline measurements at GEOSummit for a five-year period, beginning in spring 2003. It also provides for the continued operation of GEOSummit as long-term site for year-round disciplinary and interdisciplinary measurements and research. Baseline measurements include meteorology, radiation, tropospheric chemistry, snow properties and snow chemistry. Some measurements will be made in cooperation with NOAA-CMDL, e.g. carbon cycle, chlorofluorocarbons, radiation, and ozone. GEOSummit staff will also carry out measurements initiated by individual investigators. The atmospheric gas-phase and aerosol species being studied are all either sensitive indicators of anthropogenic impacts on regional and global atmospheric change, or are important chemically coupled species whose concentrations may be strongly influenced by changes in the Arctic, including changes in snow/ice surface temperatures, ice/snow cover, and atmospheric circulation. Related chemical measurements in the snow provide the needed link to investigate feedbacks between Arctic climate change, air-snow exchange, and atmospheric composition. Understanding this change requires a quantitative understanding of the environmental controls (e.g., temperature, radiation, humidity, ozone concentration) on air-snow feedbacks, and the impact of these processes on the entire Arctic atmosphere. Broader impacts. The measurements at GEOSummit have wide applicability for detecting, understanding and modeling Arctic change, and are responsive to a number of community initiatives, including the World Meteorological Organization's Global Atmospheric Watch, SEARCH (A Study of Environmental Arctic Change) and other proposed initiatives. As such, this project provides the platform and baseline measurements for a wide number of scientists and individual research projects. There are at least three main broader impacts of the project. First and foremost, by definition an environmental observatory enhances infrastructure for research and education. Second GEOSummit serves as a vehicle to broadly disseminate scientific understanding of the Arctic system by making data and information widely available, both real time data and scientific understanding that is developed using those data. Third, education of the global community is an objective of the long-term measurements, using www-available data and educational materials. GEOSummit was chosen as the site for long-term measurements because it is in the remote free troposphere, and the chemical compositional changes observed in the long term reflect wide-scale change, uncomplicated by local biochemical processes, or by local changes in land use or emission patterns. The international science community has chosen Summit for multidisciplinary, multi-investigator studies, infrastructure is in place, and a number of Arctic researchers are collaborating there. The current project builds on the intermittent (but inadequate in terms of development of reliable models) atmospheric and surface-snow measurements that have been conducted over the past decade.

Logistics Summary:
This project. Long Term Observations (LTO), will conduct a suite of year-round core measurements from 2003 through 2008. In addition to core measurements, staff will also carry out measurements initiated by up to 15-20 individual investigators, including a significant sampling campaign by NOAA (see NOAASummit). Investigators from the project will travel to Summit annually to set-up, monitor, and repair experiments as well as to conduct on-site training of the science technicians. In June 2004, two field team members assisted the Summit crew with laying out and marking the boundaries for the undisturbed, no traffic, and clean air sectors with green-flagged bamboo. In summer 2005, two team members from University of California, Merced, travelled to Summit for a single flight period. While on-site, the team conducted experiment maintenance, trained technicians, and worked with UNAVCO representatives to gather data for a topographic map of Summit. Additionally, they travelled to Nuuk to deliver a GEOSummit presentation to the Greenland Technical Society. For 2006 and onward, science technicians will continue experiments to gather baseline measurements at Summit. The PIs will combine any required site visits for this grant with fieldwork planned under other funded campaigns. In 2007, Ryan Banta will take over as the POC for the LTO grant. He and Roger Bales, along with Mark Twickler (Science Coordination Office, SCO, 0455623), will visit Summit for familiarization. In 2008, the team will not visit Summit but technicians and camp staff will continue regular maintenance to the projects. Beginning in summer 2009, measurements for this grant will be continued under 0856845 (McConnell, DRI). CPS is responsible for hiring science technicians to support the sampling and for providing the Summit infrastructure to support the work. This project combines fieldwork in support of the Summit Science Coordination Office (SCO) grant, 0455623.

Science Summary:
The Arctic environment is undergoing rapid changes, possibly due in part to anthropogenic causes. A number of these changes involve interaction with, and possibly feedback from, the atmosphere, so it is particularly important to investigate and monitor processes that could amplify atmospheric change. Complex exchange processes in the ocean-ice-atmosphere system often influence the levels of important atmospheric trace gases, such as the hydroxyl radical and ozone, and trace species are also photochemically transformed or produced within the sunlit snowpack. Because changes in Arctic atmospheric circulation are cyclic over 4-5 year or longer times, long-duration measurements are needed to understand circulation and to place observed changes in a long-term perspective. This proposal will include the development of a new generation of multi-axis differential optical absorption spectroscopy (MAX-DOAS) instruments to continually measure concentrations of the important trace species formaldehyde (HCHO), nitrous acid (HONO), nitric oxide (NO2), and halogen oxides in the Arctic. The instrument will augment ongoing observations at the Summit Greenland Environmental Observatory (GEOSummit), located at an elevation of 3100 m on the Greenland ice sheet. GEOSummit is currently the only high-altitude site for atmospheric and related measurements in the Arctic. The proposal has a strong broader impacts, especially in the area of education.

Logistics Summary:
This project will develop, install, and operate a new generation of multi-axis differential optical absorption spectroscopy (MAX-DOAS) instruments that will measure atmospheric trace gas absorption as a supplement to ongoing observations at Summit Station. The investigators plan to install MAX-DOAS at Summit in 2006. After installation and testing, the instrument will operate autonomously year-round with station science technician support. The researchers will return annually throughout the life of the grant for service and maintenance. In 2007 and 2008, PI Stutz will do any work needed on the instrument while visiting Summit Station on the Jack Dibb-led collaborative (0612075) with which he also has a grant. In 2009, a team will visit Summit Station in May to remove MAX-DOAS instruments prior to the Green House relocation. CPS will support the project via science technician services and access to the Summit Station infrastructure.

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:
Polar TREC--Teachers and Researchers Exploring and Collaborating--is a three-year teacher professional enhancement program that will advance polar science education by bringing K-12 educators and polar researchers together in hands-on field experiences in the Arctic and Antarctic. PolarTREC activities and products will foster the integration of research and education to produce a legacy of long-term teacher-researcher collaborations, improvement of teacher content knowledge and teaching practices, shareable online learning resources based on real-world science, improved student knowledge of and interest in the Arctic and Antarctic, and broad public engagement in polar science. ARCUS will adapt and extend existing Teacher Research Experience (TRE) models and its own experience delivering TREC—a TRE program supported by NSF for the Arctic—to develop PolarTREC, a comprehensive, sustained field research experience program for K-12 teachers focusing on IPY science themes at both polar regions. Thirty-six teachers will spend two to six weeks in the Arctic or Antarctic studying a topic relevant to one of the IPY emphasis areas, with "Live from IPY" calls, Internet presentations, and podcasts from the field, daily teacher journals, interactive bulletin boards, photo galleries, online multimedia learning resources and activities, and participation in CARE (Connecting Arctic/Antarctic Researchers and Educators) webmeetings to support translation of experiences into the classroom and beyond. PolarTREC is relevant to the education goals of the IPY by 1) providing a hands-on field research experience that can be realistically implemented in the polar regions; 2) broadly disseminating teacher experiences to students and other professionals; 3) developing a sustainable learning community; and 4) providing clear and appropriate measures of project success through a formative and summative evaluation. Additionally, the PolarTREC evaluation will provide a basis for replicating or expanding the program structure and best practices. PolarTREC will benefit from close coordination with logistics providers and international programs to ensure operational feasibility and an international reach. The intellectual merit of PolarTREC lies in its integration of research and education and through application and evaluation of a comprehensive approach to Teacher Research Experiences. The PolarTREC model of Teacher Research Experiences is conceived and organized according to current best practices, such as pre-research training, mentoring, support for classroom transfer, and long-term access to resources and support. PolarTREC builds on ARCUS' close relationship with polar researchers throughout the world, its established network of experienced TRE teachers, and its existing cutting-edge technical and Internet infrastructure designed for online collaboration and to bring research to classrooms and the public. The broader impacts of PolarTREC are numerous. As a formal science education project, PolarTREC advances discovery and understanding through direct impact on science teachers and students. Networks and partnerships within the polar science education and research communities will be expanded and sustained through a variety of activities, including a robust technical infrastructure designed for online collaboration and learning. The legacy of educational products developed through PolarTREC, broadly disseminated to teachers, students, and the public, will continue to influence scientific understanding of the polar regions' critical role in global processes well beyond the 72 teachers and researchers directly served through this project.

Logistics Summary:
PolarTREC teacher, Craig Beals, will join Dr. Barry Lefer (0612136- Collaborator on main grant under PI Dibb, 0612075) at Summit Station, Greenland for a field season where they are studying photochemical processes and will integrate a set of field measurements focused on the impact of halogen chemistry on the production and fate of free radicals in the Summit surface layer.

Science Summary:
Researchers on this collaborative project will investigate the importance of halogen chemistry in OH and HO2 radical production and loss above sunlit snow, and identify significant halogen sources and transport mechanisms to this unique and remote environment. Methods: They will integrate a set of field measurements focused on the impact of halogen chemistry on the production and fate of free radicals in the Summit, Greenland surface layer. They plan to make the first measurements of BrO in the boundary layer at Summit. In addition to direct measurements of HOx, the radical precursors and sinks thought to play an important role in the OH budget in this environment (O3, NO, NO2, H2O, HONO, RONO2, HCHO, HCOOH, CH3COOH, CO, CH4, and reactive NMHCs) will be measured, as well as a number of halogen species (BrO, IO, OIO, and soluble gas phase bromide). Measurements of various mercury species and NMHC oxidation products will provide additional evidence of reactive halogens. Rates of photochemical reactions will be measured above and within the snow. Measurements over a wide range of environmental (e.g., temperature, light, wind speed) conditions as well as a variety of transport regimes will help to discriminate the relative importance of halogens on HOx photochemical cycling. Field measurements will be interpreted with the aid of state-of-the-art back-trajectory tools (FLEXPART) and by employing a photochemical steady-state box-model to determine the HOx cycling within the Summit boundary layer. An advanced 1D multiphase chemical transport model (MISTRA) allows the assessment of the researchers’ understanding of HOx/halogen interactions, the discrimination of the proposed halogen sources, as well as allowing the extrapolation of their observations to other snow covered regions. Broader impacts: With only a handful of HOx measurements in snow covered regions to date, lack of understanding of HOx photochemical cycling is not surprising. If halogens play a role in the HOx cycling at Summit, atmospheric modelers will need to adjust their chemical mechanisms accordingly. This project provides an unusual opportunity for graduate and undergraduate students to participate in ground-breaking science. The researchers place a high priority on conveying their excitement and the significance of the program to students and the public through web pages tracking field campaigns and via outreach presentations in local schools. Direct teacher participation will ensure the development of materials suitable for dissemination and use in schools nationwide. The team will work with news media - including radio, newspapers, and television - to provide broad public exposure.

Science Summary:
Researchers on this collaborative project will investigate the importance of halogen chemistry in OH and HO2 radical production and loss above sunlit snow, and identify significant halogen sources and transport mechanisms to this unique and remote environment. Methods: They will integrate a set of field measurements focused on the impact of halogen chemistry on the production and fate of free radicals in the Summit, Greenland surface layer. They plan to make the first measurements of BrO in the boundary layer at Summit. In addition to direct measurements of HOx, the radical precursors and sinks thought to play an important role in the OH budget in this environment (O3, NO, NO2, H2O, HONO, RONO2, HCHO, HCOOH, CH3COOH, CO, CH4, and reactive NMHCs) will be measured, as well as a number of halogen species (BrO, IO, OIO, and soluble gas phase bromide). Measurements of various mercury species and NMHC oxidation products will provide additional evidence of reactive halogens. Rates of photochemical reactions will be measured above and within the snow.

Science Summary:
Researchers at NOAA’s Earth System Research Lab (ESRL) Global Monitoring Division (GMD) conduct continuous measurements of atmospheric composition at Summit Station to better understand changes occurring in the Arctic and Earth system. Continuous measurements include: 1. Halocarbon and other Atmospheric Trace Gases (HATS) Flasks: weekly to biweekly air sampling collection to measure trace gases that are important components of global halocarbon chemistry. These measurements have been ongoing since 2004. 2. Carbon Cycle Greenhouse Gas (CCGG) Flasks: weekly air sampling experiment to analyze levels of trace gases that are part of the global carbon cycle. These measurements were taken during winter of 1997-1998, 2000-2001, 2001-2002, and have been on-going since the 2003-2004 winter period. 3. In-situ Aerosol Sampling Suite: continual measurements of aerosol optical properties to determine aerosol radiative effects. These measurements were initiated in 2003 with an updated suite of instruments in 2009. 4. Surface ozone measurements: continual tropospheric air sampling efforts for ozone levels. These measurements were taken from 2000 to 2002, and from 2003 on. 5. Balloon-borne ozonesondes: measurements of year-round ozone atmospheric profiles. These measurements were first conducted during the late-winter of 2005. 6. In-situ Monitoring with the Chromatograph for Atmospheric Trace Species (CATS): a three-channel gas chromatograph performs hourly measurements of ozone depleting gases identified in the Montreal Protocol and amendments including nitrous oxide, sulfur hexafluoride, CFC-12, CFC-11, CFC-113, chloroform, methyl chloroform, and carbon tetrachloride. These measurements began in 2007. 7. Surface Meteorology: continuous measurements of surface meteorological properties to support both science and flight operations. These measurements have been continuous since summer 2005. 8. Surface Solar Radiation: continuous measurements of broadband solar and thermal radiation. These measurements began in 2013 with additional instruments added in 2016.

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

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

At those times, researchers will participate in a 6-8 week effort to install experiments, and then to collect data from and maintain the same. During the 2007-2008 campaigns, the research will be conducted at the Satellite Camp location from early May until mid/late June (2007) and from early June until mid-July (2008), upwind of local pollution sources from the station. The research team may total up to 15, to include one or two teacher participants and to accommodate some turnover between researchers. In 2007, PI Stutz will also conduct any work needed on his MAX-DOAS grant (0421016). PolarTREC teacher Jo Dodds (0632401JD) will join the Dibb field team as well. In 2008, Dr. Lefer will host PolarTREC teacher Craig Beals (0632401CB) who will join him in Greenland. Logistics details for this collaboration will be carried under this record, 0612075, Dibb.

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.

Science Summary:
Chemical and biological processes occuring 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 ongoing 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 led by Principal Investigators Honrath, MTU, Lead (0713992), and Helmig, CU (0713943), will conduct extensive campaign ozone and nitric oxide measurements from 2008-2010. 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). Scientists will gather their information during one extended season each at Summit Station, Greenland, and Toolik Lake Field Station, Alaska. Logistics details are found in this database under 0713992.

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:
The rate at which ice flows into the sea from the large ice sheets directly affects sea level. The forces that drive this flow are controlled by the increasingly well-known geometry of the ice-sheets, but the resistance to flow depends upon the viscous properties of ice. Ice has the peculiar property that the viscosity depends upon the rate at which the ice is deforming. This sensitivity is usually described with the Glen index. Recent theoretical studies have shown that our knowledge of the Glen index is not sufficiently developed to accurately predict very basic outcomes of marine ice-sheet change during glacial cycles; and predict the spatial dimensions of surface response in ice streams to a better accuracy than current satellite measurements. In many field measurements it is difficult to characterize the stresses very well and to know how the provenance of the ice has affected measurements. The researchers will go to divide locations where the stress field can be characterized well and the provenance is very well constrained. Radar layers provide markers within the ice, and their vertical displacement over relatively short time periods can be measured using interferometric phase-sensitive radar techniques. This will provide instantaneous vertical velocity fields and strain-rate fields in the upper third to a half of the ice field. GPS techniques will also be used to measure surface strain-rates, which can be compared with the vertical strain-rates derived from the radar. Measurements will be made at GRIP (Greenland) and at Dome C (Antarctica). At divide locations the velocity field is especially sensitive to the Glen index, and this is particularly the case in the upper part of the ice. The researchers will use full-system modeling to determine the Glen index that best fits the data, and thereby measure the Glen index in the field in a well-controlled location.

Logistics Summary:
With this NERC-funded project, a research team will conduct radar studies during two field seasons at the site of a former deep core-drilling project called GRIP, in Greenland; and at Dome C in Antarctica. This database carries information on the arctic work only. During two consecutive field seasons starting in 2008, a field team will travel to Summit Station, Greenland, via the NSF logistics chain from Kangerlussuaq. They will base at the station for about two weeks each season and travel via snowmachine to the study site, GRIP, which is about 30 km from Summit. There, they will use a stationary radar to survey a transect about 10 km long. They will take data about every 200m. The work should be finished in about five days (additional time is built in to the schedule for weather delays). In 2008, a team of three will travel to Summit from Europe early in May. The PI will work on the ice cap for about one week; his two team members will remain after his departure for the rest of the month to complete the field work. The researchers will both tent camp and make day trips to their field site. The field plan amounts to about 700 km of snowmachine travel. In addition to the radar survey, the team will make a topographic survey of the radar survey area to cover the footprint of a Danish survey over-flight. This will involve traversing parallel tracks into the radar survey area and a small additional survey grid. The four elements of the survey in order of priority are: (1) Do the five lines (five days). The most northerly line (5H north of Divide) will be done first. (2) Repeat the first line (the most northerly line) as late as possible. (3) Do CMP work. (4) Do polarimetric measurements. In 2009, a team of 2 will return to Summit Station for 2-3 weeks of measurements in May.

For each year of the grant, CPS will provide transport to and from Summit for personnel and cargo, Kangerlussuaq and Summit user days, use of on-site Summit facilities and equipment, including snowmachines a sled, fuel, and a generator. CPS will provide this support on a cost-reimbursable basis. All other support will be arranged by the PI and paid from the grant.

Science Summary:
Researchers on this collaborative project will investigate the importance of halogen chemistry in OH and HO2 radical production and loss above sunlit snow, and identify significant halogen sources and transport mechanisms to this unique and remote environment. Methods: They will integrate a set of field measurements focused on the impact of halogen chemistry on the production and fate of free radicals in the Summit, Greenland surface layer. They plan to make the first measurements of BrO in the boundary layer at Summit. In addition to direct measurements of HOx, the radical precursors and sinks thought to play an important role in the OH budget in this environment (O3, NO, NO2, H2O, HONO, RONO2, HCHO, HCOOH, CH3COOH, CO, CH4, and reactive NMHCs) will be measured, as well as a number of halogen species (BrO, IO, OIO, and soluble gas phase bromide). Measurements of various mercury species and NMHC oxidation products will provide additional evidence of reactive halogens. Rates of photochemical reactions will be measured above and within the snow. Measurements over a wide range of environmental (e.g., temperature, light, wind speed) conditions as well as a variety of transport regimes will help to discriminate the relative importance of halogens on HOx photochemical cycling. Field measurements will be interpreted with the aid of state-of-the-art back-trajectory tools (FLEXPART) and by employing a photochemical steady-state box-model to determine the HOx cycling within the Summit boundary layer. An advanced 1D multiphase chemical transport model (MISTRA) allows the assessment of the researchers’ understanding of HOx/halogen interactions, the discrimination of the proposed halogen sources, as well as allowing the extrapolation of their observations to other snow covered regions. Broader impacts: With only a handful of HOx measurements in snow covered regions to date, lack of understanding of HOx photochemical cycling is not surprising. If halogens play a role in the HOx cycling at Summit, atmospheric modelers will need to adjust their chemical mechanisms accordingly. This project provides an unusual opportunity for graduate and undergraduate students to participate in ground-breaking science. The researchers place a high priority on conveying their excitement and the significance of the program to students and the public through web pages tracking field campaigns and via outreach presentations in local schools. Direct teacher participation will ensure the development of materials suitable for dissemination and use in schools nationwide. The team will work with news media - including radio, newspapers, and television - to provide broad public exposure.

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:
Ice Stories proposed by the Exploratorium strives to create public awareness of the International Polar Year (IPY) and the multi-disciplinary range of IPY research, increase public understanding of the process of scientific research and stimulate an enhanced relationship between IPY research and public outreach activities. Primary project deliverables include: 1) Two workshops for 8-12 Arctic (workshop 1) and 8-12 Antarctic scientists (workshop 2) to train them to effectively share their science with the general public. The workshops will cover narrative storytelling, use of video and audio equipment, rough-cut editing, and hands-on camera and audio recorder training. The Exploratorium will serve as an intermediary between the scientists and the public, clarifying content, editing, curating and posting material on the Web. 2) Live Web casts from the Arctic and Antarctic eventually reach 5 a week during each field season. These involve additional scientists, with additional in-situ coverage by the Exploratorium team of Arctic and Antarctic events associated with science and IPY. 3) Creation of a public access Web site and database for educators where all materials will be posted and archived and updates will be undertaken a minimum 2-3 times each week. Materials will leverage existing resources and will include: background on major areas of IPY research, links to national learning standards in STEM (Science, Technology, Engineering, and Math), IPY history, biographies of scientists, repurposed material from past Exploratorium Antarctica projects, collected materials from research/production trips to the Arctic and Antarctic and from scientific collaborators, Pod casts, video, RSS feeds, and blogs. 4) An IPY exhibit at the Exploratorium showcasing the materials and sharing of the materials with other museums. 5) Outreach to specific after-school sites will reach underserved and underrepresented children. Independent external evaluation of the project will be conducted by Knight-Williams Research Communications.

Logistics Summary:
The Ice Stories design includes media production and narrative training, field connectivity, production capacity, media relations, and audience access. In the Arctic 2008 summer season (May to July), the team will produce live Webcasts from the field five times a week and in 2008/09 will produce live Webcasts from McMurdo Station, Antarctica and the South Pole five times a week. The technical facilities set up for these Webcasts will support the production of additional stories from the field. The team will conduct two field-tested, one-week media-training workshops for a minimum of 20 scientists in the spring and fall 2008 before the Arctic and Antarctic field seasons respectively. Field production teams will deploy to the Arctic in 2008 and be based in Barrow Alaska and Jakobshavn Glacier, Greenland. Because this is a database of Arctic fieldwork, this record will not cover the Antarctic portion of the work in detail. For the Alaska work, the Exploratorium will work with a local high school in Barrow with a production crew of 4 traveling in late May and staying through late June. This Arctic village and environs has been directly affected by shoreline erosion. Students will participate in webcasts that highlight compelling stories of environmental change. The team will work with students and teachers to give their stories a wider distribution and scope. For the work in Greenland in July, a two-person media-gathering and content production team headed by PI Mary Miller will fly to Kangerlussuaq and will visit 5 active research sites including a science team conducting glacial ice flow studies (Fahnestock, NASATHIN). One team member will fly to Summit Station for two days to interview scientists there for Ice Stories. [The team ended up collecting and posting more than a dozen video, photo and blog posts from Greenland.] In August 2009, PI will return to Greenland for 3 weeks.

CPS will arrange flights to Kangerlussuaq and Summit and NEEM via the Air National Guard. A flight of opportunity will take the team in to the Fahnestock camp (grant NASATHIN in this database) and the PI will be responsible for the payment of a helo flight out of the camp. BASC will provide support while the team is in Barrow. The PI will pay for all costs associated with this project through her 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:
As part of IPY effort 124, ASTROPOLES, this project’s scientists will explore the stability of the atmosphere above Summit, the so-called “astronomical seeing.” Astronomical seeing describes the condition of the night sky and how suitable it is for astronomical observing—that is, the amount of particulate matter in the atmosphere and how much it may impact the clarity of telescopic observations. The PI will install a small telescope on the Swiss Tower at Summit. Researchers will monitor the North Star for a month in order to measure the stability of the atmosphere above Summit, the astronomical seeing. These first measurements are essential for establishing the potential of Summit as an astronomical observing site. The telescope is a prototype of an autonomous instrument, which will operate for a whole season starting in the summer of 2009.

Logistics Summary:
This project’s PI will evaluate Summit as a site for astronomical imaging. During a four-week campaign in summer 2008, the researcher will install and collect data from a differential image motion monitor installed at 40 m height on the Swiss Tower at Summit. The project will also require bench space at a site within 500m of the tower for an associated computer, the latter of which will require data transfers of less than 1MB per day. Data collected during the campaign will be evaluated to determine whether vibrations from the tower and electronic noise affect the quality of the observations. If this test proves successful, the PI hopes to install the instrument permanently in 2009.

CPS will provide cost reimbursable transport to/from Summit for the project field team members and cargo, in-transit user days at Kangerlussuaq, access to the Summit infrastructure, and science technician support.

Science Summary:
Via this NASA-funded project, engineering students at Dartmouth College have designed and are building a robot, named “Yeti,” to conduct autonomous surveys using ground-penetrating radar (GPR) to detect sub-surface crevasses under polar snowfields. Such GPR surveys are essential to ensure the safety of over-snow traverses in Antarctica and Greenland and are currently conducted with GPR mounted to the lead manned vehicle. Yeti could improve safety, decrease costs, and increase survey coverage compared with current practice. The student team works under the supervision of roboticist Prof. Laura Ray, and the project is funded through an educational grant from NASA’s Jet Propulsion Laboratory. Dr. Steve Arcone, radar expert at the Cold Region Research and Engineering Laboratory (CRREL), initiated the project and posed the design requirements. Dr. Jim Lever, a CRREL engineer with over-snow mobility and robotics expertise, assisted with the design when he was on sabbatical at Dartmouth. The 70-kg four-wheel-drive robot is designed to tow a portable GPR unit more than 10 km over rough snowfields in less than 2 hours on a single battery charge. It will automatically return to the base camp after completing a survey. Yeti will navigate autonomously using GPS waypoint following, and will synchronize the recorded GPR and GPS data for later human analysis to detect crevasses. The robot can also be controlled manually using a radio and laptop interface. GSSI, a commercial developer of GPR, has donated a radar system to the team for field tests and has expressed interest in producing the robot if the prototype performs well. The team will complete assembly and local testing of Yeti by March 2008.

Logistics Summary:
The timely availability of Yeti offers a unique opportunity to validate it during a route survey planned by OPP for May 2008 in Greenland, to identify a traverse re-supply route from Thule AFB to Summit Station. A traverse team of two of the students from the Yeti design group will operate Yeti during the first 2 – 3 weeks of the traverse route survey, when the traverse team is working to develop a route from Thule up onto the ice cap, a distance of about 100 km. By including Yeti, it will be possible to compare the operational benefits and data quality achievable by robotic surveys directly with manned surveys. The students will leave the traverse after this initial operational period and return from Thule with the robot.

CPS will arrange military clearances for two students to fly via the Thule logistics chain and will provide cold weather gear and lodging at Thule. All other logistics will be arranged by the PI and paid for from the grant.

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:
The National Oceanic and Atmospheric Administration (NOAA) Earth System Research Laboratory (ESRL) Global Monitoring Division (GMD) conducts long-term measurements of trace atmospheric constituents that influence climate change. These measurements include carbon dioxide, water vapor, surface and stratospheric ozone, solar and terrestrial radiation, meteorology, ozone depleting compounds, and other trace constituents. These measurements are part of NOAA's effort to determine and assess the long-term buildup of global pollutants in the atmosphere. The measurements will be used for time series analysis of multiyear data records that focus on stratospheric ozone depletion, tran-arctic transport and deposition, interplay of the trace gases and aerosols with solar and terrestrial radiation fluxes on the polar region, the magnitude of seasonal and temporal variations in greenhouse gases and the potential development of polar stratospheric clouds over the Arctic. Other objectives of research are to determine the rate at which concentrations of these atmospheric constituents change and to examine the sources, sinks, distributions, budgets, and trends. Working with climate modelers and diagnosticians, we will use these data to determine how the rate of change of these parameters affect climate, particularly when the data are included in climate model studies in support of these projects.

Logistics Summary:
Weekly and bi-weekly flask samples are collected and shipped back to Boulder for analysis. All other systems are run by the local technicians at each site and the data is returned to Boulder for archival.

Science Summary:
An important issue of our time involves questions of how human activity has been impacted by the atmospheric composition of our planet. A major area as part of the International Polar Year (IPY) involves developing a better understanding of past climates and the impact of anthropogenic activity on the Earth's atmosphere. Because instrumental records of atmospheric chemistry are limited, natural archives of atmospheric composition must be made, such as polar firn. Its porous nature, tens of meters in depth, permits interstitial diffusion of gases over time with the oldest air at the bottom of the firn column which allows the sampling of large quantities of pre-industrial air to explore anthropogenic effects on the atmosphere. This project will investigate the underlying physics controlling firn's ability to store atmospheric samples from the past. The Principal Investigators will make high-resolution measurements of the diffusivity profile, permeability profile, and accompanying microstructure at Summit from the surface to pore close-off, and compare the results to the diffusivity profile inferred from measurements of firn air chemical composition. They will partner with Dr. Atsumu Ohmura, Swiss Federal Institute, and Dr. Christophe Ferrari of LGGE, France. This project has four goals: 1) Quantify the dependence of interstitial transport processes on firn microstructure, and determine the dependence of gas diffusivity on microstructure characteristics from the surface down to the pore close-off depth; 2) Quantify post-depositional changes in the physical properties of snow and firn and use measured properties of firn and meteorological data to evaluate and develop models of the physical transport processes which drive firnification where temperature gradients are large. 3) Conduct firn air chemical measurements as the firn characteristics are determined, and compare the co-registered diffusivity profile inferred from the firn air chemistry measurements to the high-resolution tracer gas measurements made on the firn core itself. 4) Use the measurements of firn air composition and firn structure to better quantify the differences between atmospheric composition (present and past), and the air trapped in both the firn, and in air bubbles within ice. Broader Impacts: This study will establish quantitative relationships that will enable a better understanding of the firn as a repository of past atmospheric composition, but will also enable us to understand mechanisms that may impact firn air composition at other sites. Results of the research will be published in journal articles and made widely available. This project will form one part of the PhD dissertation of a student from Dartmouth. Several undergraduates will be involved. They will interact with students from Switzerland and France to design and construct an IPY museum exhibit, at the Montshire Museum of Science in Norwich, Vermont. The exhibit will be interactive and will illustrate the ability of snow and firn to serve as an archive of important events of the past. It will allow the viewer to act as the "detective" to track down the meaning of different chemical composition profiles in the firn air.

Logistics Summary:
This collaborative study of firn air and structure: 0520445 (Albert, CRREL LEAD), 0520564 (Severinghaus, Scripps) and 0520460 (Battle, Bowdoin), will conduct field work at Summit Station, Greenland. Logistics details can be found under 0520445.

Initiative: http://www.geosummit.org/

Science Summary:
With this project, investigators plan to gain a better understanding of the earth's surface heat balance and the structure of the boundary layer. Investigators will make year-round observations of the surface energy balance and turbulence in the boundary layer using an instrumented, 50-meter meteorological tower, a wind-profiler, a radiometer system, and possibly an instrumented aircraft. Radiation measurements will be taken in accordance with specifications established by the Baseline Surface Radiation Network project.

Logistics Summary:
This work involves ongoing studies of the Earth's boundary layer at Summit, Greenland, and continues work begun under grant "CHAntenna" (Ohmura). See that grant in this database for a historical record of this project. After PI Ohmura retired, Konrad Steffen (University of Colorado) agreed to take over operation of the experiment. This record is for the work continued under Steffen. In 2008, three personnel will visit Summit Station in late July to conduct maintenance on the experiment. In addition, they will install an all-sky camera on the TAWO roof, add additional instruments to the Swiss Tower, and test a radiometer for potential future use. Two personnel will spend about a week on station, while the PI will join them several days later for the remainder of the week. A team of 2 will return in May 2009 to complete an AWS extension and upgrade (new satellite transmitter, new instruments), and to extend the radiation tower and conduct minor work on the instruments. They will also complete a major upgrade of the GC-Net tower and instruments and a minor maintenance of the radiation and 50 m tower instruments. After summer 2009, logistics arrangements will be carried under the Long Term Observation grant (0856845, McConnell).

CPS will coordinate the team's travel to Summit, and provide accommodations at Kangerlussuaq and Summit. CPS will also provide a dedicated weatherport for the team, provide assistance to the researchers as needed while they are on-station, and science technical staff will monitor the experiment year-round.

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

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

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

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

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

CPS will provide ANG travel and cargo support to/from Summit Station, Summit Station user days, a snow auger/corer with required tools, access to infrastructure, and year around science technician support for re-leveling the instrument, maintaining data and power cables above the snow surface, and general maintenance/troubleshooting as-needed). The PI will pay NSF directly for costs associated with this support. All other logistics will be provided by the PI.

Science Summary:
Researchers on this collaborative project will investigate the importance of halogen chemistry in OH and HO2 radical production and loss above sunlit snow, and identify significant halogen sources and transport mechanisms to this unique and remote environment. Methods: They will integrate a set of field measurements focused on the impact of halogen chemistry on the production and fate of free radicals in the Summit, Greenland surface layer. They plan to make the first measurements of BrO in the boundary layer at Summit. In addition to direct measurements of HOx, the radical precursors and sinks thought to play an important role in the OH budget in this environment (O3, NO, NO2, H2O, HONO, RONO2, HCHO, HCOOH, CH3COOH, CO, CH4, and reactive NMHCs) will be measured, as well as a number of halogen species (BrO, IO, OIO, and soluble gas phase bromide). Measurements of various mercury species and NMHC oxidation products will provide additional evidence of reactive halogens. Rates of photochemical reactions will be measured above and within the snow. Measurements over a wide range of environmental (e.g., temperature, light, wind speed) conditions as well as a variety of transport regimes will help to discriminate the relative importance of halogens on HOx photochemical cycling. Field measurements will be interpreted with the aid of state-of-the-art back-trajectory tools (FLEXPART) and by employing a photochemical steady-state box-model to determine the HOx cycling within the Summit boundary layer. An advanced 1D multiphase chemical transport model (MISTRA) allows the assessment of the researchers’ understanding of HOx/halogen interactions, the discrimination of the proposed halogen sources, as well as allowing the extrapolation of their observations to other snow covered regions. Broader impacts: With only a handful of HOx measurements in snow covered regions to date, lack of understanding of HOx photochemical cycling is not surprising. If halogens play a role in the HOx cycling at Summit, atmospheric modelers will need to adjust their chemical mechanisms accordingly. This project provides an unusual opportunity for graduate and undergraduate students to participate in ground-breaking science. The researchers place a high priority on conveying their excitement and the significance of the program to students and the public through web pages tracking field campaigns and via outreach presentations in local schools. Direct teacher participation will ensure the development of materials suitable for dissemination and use in schools nationwide. The team will work with news media - including radio, newspapers, and television - to provide broad public exposure.

Project Title: Collaborative Research: A Unique Opportunity for In-Situ Measurement of Seasonally-Varying Firn Densification at Summit, Greenland (Award# 0352584)

Science Summary:
In this project we will make detailed measurements of the temporal and spatial variations of firn compaction. This will advance knowledge and understanding within the field of ice deformation and across different fields, such as remote sensing, snow morphology, and paleoclimatology. We will make these detailed measurements throughout 2 winter and 3 summer seasons using the concept of Borehole Optical Stratigraphy, which uses a borehole camera to record details of a borehole wall. These details can be tracked over time to determine vertical motion and strain, which in the shallow depth of our study is dominated by firn compaction. Quantitative understanding of firn compaction is important for remote-sensing mass-balance studies, which seek to measure and interpret the changing height of the ice sheet; the surface can rise due to snow accumulation, and fall due to ice flow and increased densification rates. Quantitative knowledge of all 3 processes is essential. Evidence suggests that the rate of densification, which is thermally activated, undergoes a seasonal cycle, related to the seasonal cycle of temperature. When interpreting trapped-gas data from an ice core for paleoclimate, it is important to know at what point the gas was actually trapped in the ice. The pores in the ice do not close off until deep in the firn, leading to a difference between the age of the ice and the age of the trapped gas. If summer high temperatures have more impact on compaction than mean annual temperatures, the gas-age/ice-age offset might be incorrectly calculated. Greater understanding of firn densification physics will help the interpretation of these records.

Logistics Summary:
This collaborative between 0352584 (Waddington, UW) and 0352511 (McConnell, DRI) will study firn densification at several locations in Greenland using optical logging techniques the investigators developed. In 2004, this project will work closely with that of Lamorey/Waddington 0082469/0083132, combining resources and field team members. A team of two will spend 3 weeks at Summit during the setting up the winter-over experiment, collecting preliminary data, and training science technicians. The team will also conduct comparison studies at Raven for one week. At the end of the summer, a field team member will return to Raven for repeat measurements (1 week). Winter-over measurements will be carried out by science technicians already stationed at Summit as part of the winter-over science program. In 2005 and 2006, Robert Hawley will return to Summit for approximately one week in May to maintain and repair the experimental equipment, collect data, and train any new science technicians. In 2005 two British Antarctic Survey (BAS) participants will join Hawley at Summit to run high frequency Ground Penetrating Radar to obtain a detailed look at the spatial variability in firn layering. Hawley will also conduct comparison studies at Raven for one week in May of each year. At the end of the summer, he will return to Raven for a day visit to repeat the measurements. At the end of the summer 2006, he will return to Raven and Summit for a day to repeat the measurements. Accompanying him in August will be 4 staff from the American Museum of Natural History (AMNH) who are working on a documentary on Greenland, climate change, sea level, etc. They plan to feature the borehole optical stratigraphy research in their documentary, which is expected to be a main feature in the Hall of Planet Earth (estimated to be viewed by 10 million visitors per year). In addition to trips to Summit Station and Camp Raven, the field team will also visit Russell Glacier via truck after they return to Kangerlussuaq. In August 2007, Hawley will return to Summit and Raven (under a no-cost extension) to lay the ground work for an additional year of logging. First, he will visit Raven to make borehole measurements there. While at Raven he also will assist Steve Warren (University of Washington, 0612636) in collecting snow samples. At Summit, Hawley will maintain project property, including the weather station, train new wintering staff, and make "logs of opportunity" in recently drilled boreholes near camp. In addition, he will inspect the main GISP 2 borehole casing to establish what (if any) repairs need to be made. In 2008, Hawley will travel to Summit (but not Raven Camp) to retrieve and retrograde project equipment. In addition to closing out his winter-over experiment, he will undertake (as time and resources allow) 3 opportunistic experiments/activities: 1) Extend GRIP casing, if Danish scientist Dorthe Dahl-Jensen determines it is needed, and provides casing to do the job. Time to complete: one day total. 2) Make P-res measurements: this effort is collaborative with the BAS/Hindmarsh (NERCRadar) project, if time permits; the team will collect phase-sensitive radar sounding profiles at the borehole site to attempt to use the radar to measure vertical strain (in comparison to this project’s video measurements). 3) Make density-log of SUFA06: this effort is collaborative with the SPRI/Morris project. This work at the “Sandy/Zoe” site entails 40 hours of logging. Hawley plans an intensive logging effort, and expects to remain overnight at the site and complete the work in 3 to 4 days. CPS will provide infrastructure support in Kangerlussuaq, as well as access to infrastructure and services at Summit, including cold weather clothing, sleep kits and tents, use of snowmachines and communications gear.

Science Summary:
Bright surfaces (snow, glaciers, sea-ice, and clouds) make the Arctic uniquely susceptible to the radiatively-induced effects of surface light absorbing carbon (LAC, sometimes referred to as black carbon) and dust, such as ice-albedo feedback amplification. Such feedbacks may make dirty snow more efficacious than greenhouse gases in driving atmospheric temperature change in the Arctic. Dirty snow feedbacks change throughout the aerosol lifecycle in the complex Arctic environment of snowfall, snowpack aging, snow-melt, drainage, and analogous sea-ice processes. The goal of this project is to assess light absorbing aerosol interactions in the coupled Arctic climate system using models which represent the complex surface lifecycles of Arctic snow, LAC, and dust, and which have been evaluated against satellite, in-situ, and laboratory measurements. Funds are provided to use International Polar Year (IPY) field and laboratory measurements to improve the representation of snowpack microphysical processes; to implement and/or refine these processes in arctic land, atmosphere, and sea-ice components of an Earth System Model (ESM); and to use the ESM to upscale and improve quantification of the efficacy of and response to arctic climate forcing in the 20th and 21st centuries.

Logistics Summary:
This project supports the PI's participation in laboratory snow measurements with his collaborator at the French glaciology lab CNRS/LGGE. This project will also use IPY measurements to improve cryospheric models used to understand and to predict pan-Arctic climate and climate change. These studies of Arctic snow-ice-aerosol processes will improve understanding and representation of ice-albedo feedbacks and polar climate amplification. This project will not develop any Arctic climate model components from scratch. Instead intellectual efforts are used toward uncovering the influence of previously neglected snow-ice-aerosol interactions in the Arctic system. All model development tasks involve improving physics in the researcher's snow-ice-aerosol model (SNICAR) and/or merging these physics into high-quality Arctic system component models developed and maintained at national centers. Data will be obtained from other projects. Researchers will analyze samples taken at Greenland-Summit by our French collaborators. As of late 2007 the PI has no definite plans to perform Arctic fieldwork. However, the PI is working towards that goal with Greenland-Summit being the target location.

All costs associated with this project will be paid by the PI through the grant.
