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...
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 $249,863 National Science Foundation project grant through the Polar Programs federal grant program (CFDA 47.078) will fund research and educational outreach at Appalachian State University from January 2024 through December 2028. The university will conduct research to develop a process-based understanding of biophysical controls on groundwater availability in permafrost regions and quantify responses to climate change. Models and statistical analysis will generate a conceptual framework...
The National Science Foundation Division of Polar Programs awarded $209,177 under the Polar Programs federal grant program (CFDA 47.078) to Southern Oregon University to develop geospatial products mapping the capillary hydrologic system across Arctic tundra landscapes from July 1, 2023 to June 30, 2026. Field work and remote sensing analyses will produce the first pan-Arctic map of the expanding network of small surface channels and quantify their role in generating freshwater and carbon...
This $1,039,772 federal Project Grant award from the National Science Foundation's Polar Programs (CFDA 47.078) supports research by the University of Alaska Fairbanks (UAF) to study the impacts of warming saline permafrost in the Arctic. The key research objectives are to: 1) Analyze the spatial distribution and properties of saline permafrost, 2) Assess how ice wedge formation and thaw have influenced near-surface saline permafrost, and 3) Determine the response of warming saline permafrost...
This $121,069 Project Grant award from the National Science Foundation's Engineering program (CFDA 47.041) will fund a collaborative research project to understand and forecast long-term variations in the geophysical and geomechanical characteristics of degrading permafrost in Arctic Alaska due to climate change. The project will embed a 1.5-kilometer fiber-optic distributed acoustic sensing array in Utqiaġvik, Alaska to monitor permafrost conditions over time. The research team will develop...
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...
The University of Alaska Anchorage was awarded a $400,000 Project Grant from the National Science Foundation Division of Earth Sciences under the Geosciences federal grant program (CFDA 47.050). The award will fund research from September 1, 2023 through August 31, 2028 to understand changing river discharge dynamics in the rapidly warming Arctic region of Greenland. The grantee will measure components of the water cycle across watersheds with varying glacial coverage in Greenland. Field data...
This National Science Foundation (NSF) Polar Programs grant, awarded under CFDA 47.078, supports a research project at the University of New Mexico (UNM) to study the physical and chemical drivers of carbon cycling in Arctic landscapes. The $149,288 award will fund one postdoctoral researcher and analysis of field samples collected from the Canning River in Alaska. The project aims to develop a model simulating carbon flow across the Arctic landscape, including the transformation of...
