This $199,879 project grant from the National Science Foundation's Geosciences program (CFDA 47.050) funds research at the University of Alaska Southeast to evaluate how changing glaciers influence the movement of freshwater, nutrients, and minerals from coastal watersheds in Southeast Alaska to nearshore waters in the Gulf of Alaska. Under the award, set to run from January 1, 2023 to December 31, 2024, project personnel will sample rivers with glaciers throughout the year and intensely...
The National Science Foundation Division of Earth Sciences awarded $627,744 under the Geosciences federal grant program (CFDA 47.050) to The Washington University from July 2022 to June 2025. This Project Grant will support research aimed at developing a physical model to assess the sensitivity of mountain river channels to shifts in climate and associated hazards. Specifically, the grant will fund 1) analysis of high-resolution topography and sediment transport data to establish baseline...
This Project Grant from the National Science Foundation's Geosciences program (CFDA 47.050) provides $136,638 to Oregon State University to support research measuring sediment fluxes in boreal rivers in Alaska. The funding will be used to leverage recently developed do-it-yourself optical backscatter sensors to improve measurements of Arctic fluvial sediment fluxes. These lower-cost sensors will be enhanced with separate data logging and power capabilities as well as satellite-enabled data...
The National Science Foundation Division of Earth Sciences awarded Washington State University a $273,481 Project Grant under the Geosciences federal grant program (CFDA 47.050) to conduct collaborative research from January 1, 2022 to December 31, 2024. The research aims to inform river corridor transport modeling by harnessing community data and physics-aware machine learning. The Geosciences program supports basic research to strengthen understanding of Earth's integrated system through...
This five-year, $460,399 project grant from the National Science Foundation's Geosciences program (CFDA 47.050) will fund research and education initiatives focused on improving flood hazard assessments. The principal investigator at Northeastern University will establish a long-term floodplain sedimentation observatory and develop hydraulic models to better understand landscape controls on alluvial sedimentation patterns. This work will help constrain flood hazard estimates through...
The National Science Foundation awarded a $306,062 Project Grant to Princeton University under the Geosciences program (CFDA 47.050) to conduct collaborative research from April 2022 through March 2025. The research aims to advance understanding of cohesive sediment transport through multiscale experiments and numerical simulations. Specifically, the university will combine nano- to microscale imaging and molecular dynamics simulations, micro- to mesoscale millifluidic experiments and...
This three-year, $234,084 project grant from the National Science Foundation's Geosciences program (CFDA 47.050) supports collaborative research on the geomorphic legacy of megaflood deposits in the Eastern Himalaya. The grantee, the University of Washington, will investigate how catastrophic flood events contributed to the evolution of steep, high-relief mountain landscapes through unique flood deposits in the region. The project team will determine the source, depositional age, and grain...
This $372,598 Project Grant awarded by the National Science Foundation's Geosciences Program (CFDA 47.050) will support research to incorporate stream biogeochemistry into carbon assessment models for enhanced rock weathering, a carbon dioxide removal approach. The project aims to add biological processes like photosynthesis and respiration into a dynamic river network model to better quantify the fate of bicarbonate generated through enhanced rock weathering. This will help identify river...
This $256,252 National Science Foundation award under the Geosciences program (CFDA 47.050) will fund research by the Aspen Global Change Institute to estimate the emergence of anthropogenic warming signals in snow water resource metrics in mountainous regions. The three-year project grant will use an innovative modeling framework including a large ensemble climate model, statistical learning techniques, and process-based hydrological modeling to analyze uncertainty and attribute changes in...
This $735,074 federal Project Grant award was provided by the National Science Foundation's Geosciences Program (CFDA 47.050) to the University of Washington. The primary objectives of this 3-year grant, which runs from September 1, 2026 to August 31, 2029, are to: Develop a comprehensive, AI-ready dataset of topographic, meteorological, and environmental variables for major wildfires across the western U.S. This dataset will serve as the foundation for probabilistic models to predict...
This $148,707 Project Grant awarded by the National Science Foundation's Geosciences Program (CFDA 47.050) supports a research project titled "EMBRACE-EAR-SEED: Meltwater and Suspended Sediment in a Glaciated Volcanic Watershed." The project aims to use the mineral composition of suspended sediment in the Puyallup River watershed in Washington state to determine the fraction of sediment coming from lowland versus upland sources as glaciers retreat and rainfall patterns shift due to climate change. The research will map the iron-bearing mineral fraction of sediment sources and identify links between sediment sources, rainfall, and glacial melt. This information will help reconstruct historical hydrologic patterns in the region over the past century using sediment accumulated in Commencement Bay. The project will also facilitate undergraduate education and inform water quality, conservation, and restoration efforts in the surrounding area. No subwards are planned for this award.
