This $705,367 federal Project Grant award from the National Science Foundation's Polar Programs (CFDA 47.078) will support a collaborative research project investigating the physical feedbacks in the coastal Alaskan Arctic during the landfast ice freeze-up period. The research will utilize a variety of instruments, including moorings, autonomous systems, and seafloor cables, to capture the spatial and temporal variability in the freeze-up processes along the Alaskan Beaufort shelf. The project...
The National Science Foundation (NSF) awarded a $379,007 Project Grant under its Polar Programs (CFDA 47.078) to Oregon State University (OSU). The 3-year grant, which runs from May 1, 2024 to April 30, 2027, will fund collaborative research to study physical feedbacks in the coastal Alaskan Arctic during the landfast ice freeze-up period. The research aims to better understand how waves, storms, and sediment interact during the fall freeze-up in the region, which has experienced rapid...
This Project Grant award from the National Science Foundation's Polar Programs (CFDA 47.078) provides $335,701 to the University of Alaska Fairbanks to study how the ocean affects landfast sea ice, especially during the spring and autumn seasonal transitions, in Alaska's Arctic coastal communities. The research aims to improve forecasting and understanding of landfast ice breakup and freeze-up events, which are critical for safe hunting and travel activities. The project will collect ocean...
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 Project Grant from the National Science Foundation Division of Polar Programs, under the Polar Programs federal grant program (CFDA 47.078), provides $214,041 to the University of Washington from April 15, 2022 to March 31, 2024. The funding will support persistent measurements of surface waves in landfast ice using fiber optic telecommunication cables. Researchers will measure waves along a seafloor cable and with surface buoys over week-long periods in spring, summer, and fall of 2022....
The National Science Foundation's Polar Research (CFDA 47.078) program awarded the University of Washington a $327,580 project grant to elucidate the ocean dynamics governing melt at glaciers using Lagrangian floats. The 3-year grant, awarded on October 1, 2023, will develop instruments that drift in three dimensions to study the physical processes causing melting at an Alaskan glacier ending in a fjord. The project aims to determine whether recirculating cells and waves below the sea surface...
This $239,286 Project Grant award from the National Science Foundation's Polar Programs (CFDA 47.078) will fund the "Sikumiut: An Utqiagvik Sea Ice Field School" at the University of Washington. The project aims to bring together indigenous knowledge holders, numerical modelers, remote sensing experts, and field observers to collaboratively learn about and share knowledge on Arctic sea ice changes. Key activities include a virtual seminar series, a 1-week field school in Utqiagvik,...
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 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 federal Project Grant award, provided by the National Science Foundation's Polar Programs (CFDA 47.078), is focused on developing and validating multiscale numerical models that connect the micromechanics of sea ice to its macroscopic behavior under various environmental conditions. The primary objectives are to: (i) analyze the internal structure of sea ice using high-resolution X-ray computed tomography imaging; (ii) simulate microscale interactions and failure mechanisms using discrete...
