This Project Grant award from the National Science Foundation Division of Ocean Sciences will fund research investigating ocean stratification changes with global warming by long-range internal tides. The $615,534 award to the University of Washington will support the development of techniques to accurately observe low-mode internal tides using satellite altimetry. The research aims to improve understanding of internal tide activities and develop a new method for monitoring ocean...
This National Science Foundation (NSF) Geosciences Program (CFDA 47.050) Project Grant award in the amount of $353,715 will fund a collaborative research project to study the turbulence in the stratified layer at the air-water interface, as driven by waves and wind. The project will utilize a combination of controlled laboratory experiments and advanced numerical simulations (large-eddy simulations) to test the hypothesis that coupling between waves and wind-driven currents is necessary to...
This National Science Foundation (NSF) Project Grant award under the Geosciences program (CFDA 47.050) is funding research to examine the effects of surface wave direction and wave breaking on wave-induced transport and air-sea interaction. The $129,932 award to the University of Rhode Island supports theoretical, numerical, laboratory, and observational studies to advance the understanding of ocean surface wave geometry, kinematics, dynamics, and statistics, and their role in the physical...
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 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) will fund research to investigate the interactions between internal waves and submesoscale currents in the ocean's bottom boundary layer. The total award is $418,382 over a period of 3 years, from June 1, 2024 to May 31, 2027. The research will combine theoretical concepts, analyses of existing measurements, and computer modeling to assess how these wave-current interactions affect mixing and...
This National Science Foundation (NSF) Division of Ocean Sciences Project Grant, funded under the Geosciences program (CFDA 47.050), supports collaborative research to map the spatial and temporal patterns of internal gravity wave (IW) dissipation and mixing using global observations, numerical simulations, and theory. The $884,427 award, effective September 1, 2023 through August 31, 2026, will employ global and regional IW models, as well as observational data from sources like Argo floats and...
This $313,825 two-year Project Grant from the National Science Foundation's Geosciences program (CFDA 47.050) supports research into submesoscale instabilities and energy cascades in seamount wakes. The University of Maryland, College Park will use large eddy simulations and Reynolds-averaged modeling to investigate how submesoscale processes impact dissipation, mixing, and the representation of seamount energetics in climate models. Specifically, the awardee will examine the forward energy...
This National Science Foundation (NSF) Project Grant award under the Geosciences Program (CFDA 47.050) provides $702,603 from September 1, 2024 to August 31, 2027 to Texas A&M University-Corpus Christi (TAMU-CC) to conduct a comprehensive study on large-scale deep cycle turbulence (DCT) variation in the equatorial oceans. The primary objectives are to investigate the spatial and temporal variation of DCT and quantify its influence on sea surface temperature (SST) and upper ocean heat...
