Project Grant 80NSSC24K1029

This Project Grant award of $317,795 from the National Science Foundation Division of Polar Programs (CFDA 47.078) supports research by the Colorado School of Mines to disentangle the internal and basal processes that influence ice sheet flow and contribute to sea-level rise. The project combines satellite remote sensing data with ice-penetrating radar observations to partition the contributions of internal and basal friction within the ice sheet. Key efforts include developing open-source...

This Project Grant from the National Science Foundation's Polar Programs will support research to enhance understanding of cloud impacts on the surface energy budget of the Antarctic Peninsula. With total funding of $248,364, the award period is from February 1, 2022 through July 31, 2024. The University of California San Diego's Scripps Institution of Oceanography, as awardee, will use surface-based and satellite measurements to characterize clouds and humidity in the region. Researchers will...

This $204,278 Project Grant award from the National Science Foundation's Polar Programs (CFDA 47.078) will support research by the University of Chicago to investigate how Arctic sea ice attenuation affects ocean swell, microseisms, and the potential to use seismology as a method for observing sea ice conditions. The key activities include: Analyzing seismic data from stations along the northern coasts of Alaska, Canada, and Greenland to detect seasonal and annual changes in microseisms as a...

This $392,618 federal Project Grant award from the National Science Foundation's Polar Programs (CFDA 47.078) will support collaborative research to investigate the combined impact of atmospheric rivers and foehn warming on surface warming and melting over West Antarctica. The research will utilize high-resolution numerical weather prediction simulations and existing satellite/ground observations to examine the physical mechanisms behind these extreme weather events and their contribution to ice...

This three-year, $361,678 National Science Foundation project grant supports research investigating the importance of sea-level feedbacks in stabilizing marine-based ice sheets during retreat. Funded under the Geosciences program, which supports basic research expanding understanding of the integrated Earth system, the University of California, Santa Barbara will combine new late Pleistocene/Holocene relative sea-level data from Scotland with ice sheet and glacial isostatic adjustment...

This Project Grant award of $231,050 from the National Science Foundation's Polar Programs (CFDA 47.078) will fund research to investigate the mechanisms that relate ocean circulation in the open ocean to ice sheet melt in Antarctica. The primary objectives are to: 1) Quantify the pathways of Circumpolar Deep Water from its origin in the Antarctic Circumpolar Current to the Antarctic continental slope, and 2) Determine the physical mechanisms that govern the variability of these pathways. The...

This National Science Foundation (NSF) Polar Programs (CFDA 47.078) Project Grant award to the University of Washington is valued at $575,572 and supports research to understand the response of two of East Antarctica's most vulnerable glaciers, Totten and Denman, to ocean warming and the resulting impact on sea level rise. The project will use numerical models constrained by oceanographic and remote sensing observations to determine how these glaciers will respond to increased melting. This...

This Project Grant award of $859,378 from the National Science Foundation's (NSF) Polar Programs (CFDA 47.078) supports a collaborative research project exploring the dynamics of ice shelf boundaries in Antarctica. The research aims to investigate areas where floating ice shelves compressively flow against obstructions, as these "crash-zones" generate resistive forces that impact ice sheet contributions to sea-level rise. The project will feature on-site glaciological and geophysical...

This Project Grant awarded by the National Science Foundation's Polar Programs (CFDA 47.078) provides $380,593 to the University of Georgia Research Foundation to conduct research on the Bellingshausen Sea and its role in Antarctic ice sheet mass loss and ocean carbon uptake. The project, titled "BEACON: The Bellingshausen Sea, A Carbon and Overturning Nexus," aims to collect physical and biogeochemical observations to assess the Bellingshausen Sea's influence on large-scale heat,...

This $362,718 National Science Foundation Division of Polar Programs Project Grant will support research to improve model representations of Antarctic ice-shelf instability and break-up due to surface meltwater processes. The Regents of the University of Colorado will receive funding from January 1, 2023 through December 31, 2025 to develop a new component for the continental-scale Ice-Sheet and Sea-Level System Model (ISSM) capable of simulating surface meltwater-induced flexure, fracture,...
