Project Grant 2234120
- This $193,418 National Science Foundation project grant through the Polar Programs federal grant program (CFDA 47.078) will fund research at the University of Alaska Fairbanks to map the capillary hydrologic system across Arctic tundra regions and assess its role in freshwater and carbon flows to major rivers. The three-year research project will use graph analysis techniques and deep learning algorithms applied to high-resolution satellite imagery to map ice wedges and the expanding capillary...
- This three-year, $302,382 project grant from the National Science Foundation Division of Polar Programs will support the Woodwell Climate Research Center Inc. in mapping the capillary hydrological system across Arctic tundra regions. As permafrost thaws due to climate change, dense networks of small surface drainage channels are forming and expanding. These "capillaries" represent the origin of water flowing into large Arctic rivers and influence habitat, infrastructure hazards, and...
- The National Science Foundation Division of Polar Programs awarded $358,030 under the Polar Programs (CFDA 47.078) federal grant program to the University of Connecticut from July 1, 2023 to June 30, 2026. The award will support mapping of the capillary hydrological system across Arctic tundra to assess its role in generating water flow and lateral carbon flux to large rivers. Researchers will apply graph analysis techniques and deep learning algorithms to pan-Arctic ice-wedge polygon maps and...
- This National Science Foundation (NSF) Polar Programs (CFDA 47.078) Project Grant award of $139,073 supports collaborative research to map the extent of the Arctic capillary hydrological system and advance understanding of how it has changed over time. The project aims to produce a pan-Arctic map of the capillary drainage network, which serves as an indicator of ice-rich permafrost thaw, and make the geospatial data publicly accessible. Field observations have shown increased Arctic river runoff...
- This $1.125 million project grant from the National Science Foundation Office of Integrative Activities, under the Geosciences program (CFDA 47.050), will fund research and development of water and sanitation resilience strategies for rural Alaskan communities facing environmental change. Over a three-year period from January 2023 through December 2026, the University of Massachusetts will work with community partners in Kongiganak and Mekoryuk to evaluate near-term and long-term water provision...
- This Project Grant award, funded by the National Science Foundation's (NSF) Polar Programs (CFDA 47.078), is mapping the distribution of freshwater and dissolved organic matter in the Arctic Ocean over a 20-year period. The $648,455 award, effective September 1, 2025 through August 31, 2028, will combine data on organic matter composition, salinity, temperature, and water isotope composition to identify sources and variability of freshwater in the Arctic. This research aims to advance...
- This $700,962 Project Grant award from the National Science Foundation's Polar Programs (CFDA 47.078) will fund a collaborative research study on how meltwater from surface channels affects the subglacial drainage system beneath Greenland's glaciers. The investigators will conduct a field study using seismic sensors, radar, and ice movement measurements to track the evolution of underground drainage cavities and how their connectivity impacts seasonal changes in ice velocity. The research builds...
- The National Science Foundation (NSF) awarded a $1,170,034 Project Grant under the Polar Programs (CFDA 47.078) to the University of Maine System to quantify the biogeochemical cycles and forecast future scenarios for sub-Arctic agroecosystems from Alaska to Greenland. The 3-year project, beginning January 1, 2026, will investigate the impacts of expanding agricultural practices on Arctic and sub-Arctic freshwater systems and ecosystems. The researchers will partner with 6 farms in South...
- This Project Grant award from the National Science Foundation Division of Earth Sciences provides $295,705 to Appalachian State University from January 1, 2022 through December 31, 2024. The funding supports collaborative research titled "Zero-Order to First-Order: Hydrologic Drivers of Surface-Subsurface Storage Dynamics in Thawing Permafrost Landscapes." The research aims to improve understanding of hydrologic processes in areas with thawing permafrost. Specifically, the university...
- This $191,868 National Science Foundation project grant supports research to understand surface-to-bed meltwater pathways across the Greenland Ice Sheet. Funded through the Polar Programs grant program (CFDA 47.078), the award will utilize machine learning and physics-based models to map cracks and draining lakes on the ice sheet from satellite imagery. Researchers at the University of Kansas Center for Research will develop open-source artificial intelligence codes to automatically detect ice...
This three-year, $294,517 National Science Foundation Division of Polar Programs project grant will support the development of geospatial products mapping the capillary hydrological system across Arctic tundra regions. The University of Massachusetts Amherst will produce a pan-Arctic map of the expanding network of small surface drainage channels that originate freshwater flows to larger Arctic rivers. Researchers will apply graph analysis techniques and deep learning algorithms to very high-resolution satellite imagery to map ice wedge polygons and detect the capillary system across the tundra. Complementary field work in northern and northwestern Alaska will include geochemical water sampling, permafrost coring to assess ice wedge status, and ground-truthing to support remote sensing analyses. This new mapping data will inform numerical hydrology modeling to quantify the capillary system's contribution of freshwater and lateral carbon fluxes to the Arctic Ocean. The geospatial products will be publicly accessible through the Permafrost Discovery Gateway to enable scientific discovery and knowledge generation regarding Arctic hydrological changes and infrastructure hazards from thawing permafrost.
