This three-year, $482,834 project grant from the National Science Foundation's Geosciences program (CFDA 47.050) will support analysis of Lagrangian observations from vertically profiling floats to investigate levels of internal waves and their role in transforming water properties through vertical mixing along the Pacific-to-Indian Ocean throughflow pathway. Specifically, the award recipient, the University of Washington Office of Sponsored Programs, will utilize existing and new float...

This National Science Foundation Project Grant award of $489,375 supports the development and validation of an in-situ particle tracking velocimetry system for ocean turbulence measurement by Stanford University from August 2022 through July 2025. The award advances the Geosciences program's goal of expanding fundamental knowledge of the integrated Earth system through basic research in atmospheric, earth, and ocean sciences. Specifically, the grantee will bridge current gaps in understanding...

The National Science Foundation Division of Ocean Sciences awarded a $199,831 Project Grant to the University of Hawaii at Manoa under the Geosciences program (CFDA 47.050) to support the final development and at-sea testing of a Hadal Water Column Profiler. The profiler, capable of reaching depths of 11 km, will allow for repeated vertical profiling of temperature, conductivity, dissolved oxygen, turbulent mixing, current velocity, acoustic backscatter, and video. It also features an...

This three-year, $473,907 Project Grant from the National Science Foundation Division of Ocean Sciences will support research into quantifying the exchange processes between the ocean surface boundary layer and interior at submesoscales. Submesoscale interactions between currents, waves, and turbulence can significantly impact biogeochemistry and climate through entrainment and subduction of tracers between layers. The awardee, Brown University, will conduct numerical simulations and develop new...

This two-year, $339,657 National Science Foundation project grant will support the analysis of thirty years of surface current mapping data from high-frequency radar along the U.S. West Coast. The University of California Santa Cruz will acquire historical radar datasets from multiple sources, conduct quality control procedures, and pair the current data with high-resolution wind field analyses from the Coupled Ocean/Atmosphere Mesoscale Prediction System atmospheric circulation model. The...

This $296,858 National Science Foundation project grant supports research into the dynamics of near-surface ocean velocity structures through the Geosciences program (CFDA 47.050). The University of Maine will collaborate with other institutions to elucidate upper-ocean hydrodynamics using observational data, numerical modeling, and fieldwork. Specifically, the grantee will pair existing high-frequency radar measurements with upward-looking current profilers to investigate the influence of...

This federal Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) provides $299,987 to the University of Washington to develop "Bobberone", a low-cost, portable float that will use acoustic sensing to detect regionally important zooplankton, fish, and marine mammals in near real-time. The float will integrate active and passive acoustic sensing with edge processing and cloud connectivity to support cross-trophic biological observation in...

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 National Science Foundation project grant of $568,415 supports research into submesoscale ocean processes through May 2025. Funded under the Geosciences program (CFDA 47.050), the award will advance understanding of exchange between the well-mixed surface layer and stratified interior of the ocean at horizontal length scales of hundreds to thousands of meters. Major activities include Reynolds-averaged numerical simulations to quantify the impact of incorporating entrainment fluxes into a...

This three-year, $654,518 project grant from the National Science Foundation's Division of Ocean Sciences, under the Geosciences program (CFDA 47.050), will support the University of Maine in developing an open, platform-agnostic sediment trap controller and imaging sensor to measure sinking organic carbon fluxes in the ocean's mesopelagic zone (500-1,000 meters). Specifically, the University will create a controller to simplify the construction and deployment of neutrally buoyant sediment traps...
