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, $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 $369,854 National Science Foundation Division of Polar Programs project grant will support research to further understanding of Arctic sea ice variability in the 20th century. Specifically, the University of Washington will produce a new, physically realistic reconstruction of Arctic sea ice and sea surface temperatures during the 20th century. This reconstruction will be used to study Arctic sea ice during the early 20th century warming period from 1915 to 1940, when the Arctic warmed...
This Project Grant award from the National Science Foundation Division of Polar Programs (CFDA 47.078) provides $161,000.00 to the University of Washington to conduct collaborative research assessing the causal influence of atmospheric opacity (i.e., clouds) and sea ice on Arctic warming over the period 1980 to 2060. The research will leverage a well-established NSF-funded Earth System Model and observations, including data from the recent MOSAIC field campaign, to quantify how these factors...
The National Science Foundation awarded a $535,065 Project Grant to the University of Washington under the Polar Programs federal grant program (CFDA 47.078) to support research titled "COLLABORATIVE RESEARCH: SPATIOTEMPORAL VARIABILITY OF SOLAR RADIATION PARTITIONING IN THE SEA ICE SYSTEM: IMPROVING CLIMATE MODELS USING OBSERVATIONS FROM THE MOSAIC FIELD CAMPAIGN." The grant period runs from January 15, 2022 through December 31, 2024. Under this award, the University of Washington...
This National Science Foundation project grant of $401,241 will fund research at the University of Washington from May 2022 through April 2025 to advance understanding of Arctic sea ice interactions with tropospheric polar vortices and cyclones. The grant was awarded under the Polar Programs federal grant program (CFDA 47.078), which supports basic research in polar regions. Specifically, the researchers will investigate coupling between tropospheric polar vortices, Arctic cyclones, and...
This Project Grant from the National Science Foundation Division of Polar Programs, under the Polar Programs federal grant program (CFDA 47.078), provides $560,052 to Colorado State University to improve seasonal sea ice extent predictability in the Arctic Ocean. The research aims to use ocean heat patterns and the timing of autumn sea ice freeze up from reanalysis data and the CESM2 Large Ensemble to evaluate which environmental variables most significantly contribute to sea ice loss. The grant...
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...
This Project Grant from the National Science Foundation Division of Polar Programs, under the Polar Programs federal grant program (CFDA 47.078), provides $371,742 to the University of Washington from January 1, 2023 through December 31, 2025. The funding will support development of a new modeling component for the continental-scale Ice Sheet and Sea Level System Model (ISSM). This new component aims to simulate surface meltwater-induced flexure, fracture, and large-scale ice shelf break-up in...
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...
