This $590,883 Project Grant from the National Science Foundation Division of Polar Programs will fund research into sea ice-ocean exchange of microplastics in the Arctic. The grant was awarded on March 1, 2022 to the Regents of the University of Colorado under the NSF's Polar Programs CFDA number 47.078. Through a combination of laboratory studies and numerical modeling, researchers will develop new techniques to understand the uptake and release of microplastics between sea ice and ocean water,...
This Project Grant from the National Science Foundation Division of Polar Programs supports collaborative research on sea ice-ocean exchange of microplastics in the Arctic. The $111k award runs from March 2022 through February 2026. The researchers are developing new laboratory techniques and numerical models to understand the uptake and release of microplastics between Arctic sea ice and the ocean, including the effect of marine gels. Laboratory studies are measuring the optical properties of...
The National Science Foundation awarded a $449,936 Project Grant to the University of Washington under the Engineering federal grant program (CFDA 47.041) to study particle dynamics at the ocean surface from February 1, 2023 through January 31, 2028. The award will support research to observe microplastic particles in laboratory-generated ocean flows and develop a modeling framework describing the vertical mixing and transport of plastics near the ocean surface. The investigator will partner...
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 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...
The National Science Foundation awarded $213,300 under the Polar Programs federal grant program (CFDA 47.078) to the University of Washington for the period September 1, 2022 through August 31, 2024. Through model-observation synthesis, this Project Grant will characterize the hydrographic conditions and dynamics of the Marginal Ocean Zone in the Arctic Ocean. The researchers will synthesize available data to define the Marginal Ocean Zone based on ocean properties like temperature, salinity,...
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 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...
The University of Washington was awarded a $983,607 Project Grant from the National Science Foundation Division of Polar Programs to conduct research titled "COLLABORATIVE RESEARCH: GRATE ? INTEGRATING DATA AND MODELING TO QUANTIFY RATES OF GREENLAND ICE SHEET CHANGE, HOLOCENE TO FUTURE." The period of performance for this research is from September 1, 2021 through August 31, 2025. The grant was awarded under the NSF's Polar Programs (CFDA 47.078) to strengthen understanding of polar...
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...
