Project Grant N000142612101

This $304,752 National Science Foundation Division of Polar Programs award will fund research to improve climate model simulations of sea ice physics and feedbacks through analysis of observations from the Multidisciplinary Drifting Observatory for the Study of Arctic Climate field campaign. The University of Washington will integrate spatially and temporally coordinated field observations with single column and global climate modeling to develop parameterizations that more accurately...

This three-year, $411,911 National Science Foundation Division of Polar Programs project grant will fund research to advance sea ice floe-size distribution and wave-ice interaction modeling capabilities within fully-coupled Earth system models. The University of Washington will receive funding to incorporate prognostic floe-size distribution components into widely-used sea ice and wave models, and parameterize wave attenuation in sea ice through data assimilation methods. Model code improvements...

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 $325,213 Project Grant awarded by the National Science Foundation's (NSF) Division of Polar Programs (CFDA 47.078) to The Trustees of Columbia University in the City of New York will investigate the role of meltwater in governing the geophysical properties of deforming icy systems. The project aims to create new flow laws that explicitly incorporate the effects of meltwater on ice flow, which is a key factor in modeling glacial mass loss and sea level rise. The research will employ...

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 $870,804 federal Project Grant award from the National Science Foundation's (NSF) Polar Programs (CFDA 47.078) will support a 5-year research project at the University of Washington focused on improving the representation of small-scale sea ice processes in climate models. The key objectives are to refine the modeling of sea ice deformation and fractures at the floe scale, and establish connections between these small-scale dynamics and larger-scale sea ice behavior. This will involve a...

This three-year, $175,836 National Science Foundation Division of Polar Programs project grant will support collaborative research characterizing eddies beneath Antarctic sea ice. The University of Washington will analyze hydrographic observations from ARGO floats and instrumented seals to statistically characterize sub-sea ice eddy properties. High-resolution global ocean and sea ice models will be used to track simulated eddies back to formation sites to identify mechanisms. Theoretical...

The National Science Foundation's (NSF) Polar Programs (CFDA 47.078) awarded a $288,448 project grant to Oregon State University (OSU) on June 15, 2025. The grant will fund collaborative research to develop and validate multiscale numerical models that link the micromechanics of sea ice to its macroscopic behavior. The research aims to uncover how sea ice microstructural features, such as grain size, porosity, and void distribution, influence its ability to withstand environmental and mechanical...

The National Science Foundation awarded a $600,397 Project Grant under the Geosciences program (CFDA 47.050) to the University of Montana to develop innovative, physics-informed models of two critical processes in ice dynamics: basal sliding and ice front calving. The project aims to improve predictions of how quickly the Greenland and Antarctic ice sheets will respond to climate change, which is crucial for planning infrastructure, protecting coastal populations, and informing policy decisions....

The National Science Foundation Division of Polar Programs awarded a $660,800 project grant to the Georgia Tech Research Corporation to develop new models of glacier-ocean boundary layer interactions through laboratory experiments and numerical modeling. The award falls under the Polar Programs federal grant program (CFDA #47.078), which supports basic research in the polar regions. Specifically, the grantee will conduct comprehensive laboratory experiments using laser-based techniques to gather...
