The funding supports a collaborative U.S./U.K. research project investigating the direct influence of meltwater on the dynamics of the Antarctic ice sheet. The key activities include a field campaign on Flade Glacier and a continent-wide remote sensing survey to test hypotheses related to how surface meltwater reaching...
- The University of Wisconsin-Madison received a three-year, $361,527 project grant from the National Science Foundation to conduct collaborative research on interactions between Arctic cyclones, atmospheric rivers, and sea ice in a warming climate. The research will be conducted under the NSF's Polar Programs, which provides funding to strengthen understanding of the polar regions through basic research best or only conducted in the Arctic and Antarctic. The University of Wisconsin System,...
- This Project Grant from the National Science Foundation Division of Polar Programs, under the Polar Programs federal grant program (CFDA 47.078), provides $269,022 to support research aimed at improving ice shelf instability and breakup modeling. Specifically, the University of California, Los Angeles will develop a new component for the continental-scale Ice Sheet and Sea Level System Model to simulate surface meltwater-induced flexure, fracture, and large-scale ice shelf breakup. To achieve...
- This $400,757 Project Grant awarded by the National Science Foundation's Division of Polar Programs (CFDA 47.078 - Polar Programs) to the University of Wisconsin-Madison will fund a research project to determine the fundamental processes that control the geometry of subglacial cavities formed as glaciers slide over bedrock. The research will use a novel experimental device to systematically assess how factors like effective stress, sliding speed, and bedrock bump geometry affect cavity...
- 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,...
The National Science Foundation Division of Polar Programs awarded the University of Wisconsin - Madison $198,950 on September 1, 2026, under the Polar Programs assistance listing (CFDA 47.078) to produce three-dimensional maps of the Nansen Ice Shelf front in Antarctica, combining multibeam sonar imaging of underwater sections with photogrammetry of above-water sections. This direct observation effort aims to constrain ocean-ice interactions and ice rheology by distinguishing between competing mechanisms that drive ice shelf front bending and iceberg calving. The project period runs through August 31, 2027, with performance at the University of Wisconsin - Madison in Madison, Wisconsin. The research addresses a fundamental gap in understanding Antarctic ice shelf dynamics. Satellite lidar data show upward bending of some ice shelf fronts by more than 10 meters, contrary to classical theory predicting only downward bending. The leading explanations are either that wave erosion creates submerged ice benches that buoyantly push the front upward, or that vertical viscosity variations in the ice drive bending through internal stresses. Direct three-dimensional mapping of both underwater and above-water cliff geometry for the first time will test these competing hypotheses and improve constraints on ice sheet and sea level projections. The insights may also extend to understanding ice properties on icy planets beyond Earth.
