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 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 Project Grant from the National Science Foundation Division of Ocean Sciences, under the Geosciences federal grant program (CFDA 47.050), provides $197,506 to support collaborative research on rapid pilot observations of enhanced near-bottom equatorial turbulence in the deep Pacific Ocean. The University of California San Diego Scripps Institution of Oceanography, as awardee, will leverage an existing mooring array at 140°W to add instrumentation to moorings planned for 0.5°N and 3°N...
- This National Science Foundation Project Grant of $1,078,024 will fund research to reconstruct climate linkages across the tropical oceans over the last millennium through May 2025. Under the Geosciences program (CFDA 47.050), which supports basic research in atmospheric, earth, and ocean sciences, the University of Michigan will produce new paleoclimate records of sea surface temperature using the geochemistry of long-lived corals from the tropical North Atlantic and western Indian Ocean....
- The Woods Hole Oceanographic Institution was awarded an $832,021 Project Grant from the National Science Foundation Division of Ocean Sciences under the Geosciences federal grant program (CFDA 47.050) to disentangle drivers of heat and freshwater transport through the Indonesian seas across timescales. The Institution will combine data from sediment cores with model simulations to investigate 1,100 years of changes in the Indonesian Throughflow. As part of this work, K-12 educational materials...
- This $498,929 federal Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) will support collaborative research to investigate the decay mechanisms of internal tides and their impact on the heat budget in the equatorial Pacific Ocean. The research team at the University of Southern Mississippi will use high-resolution numerical ocean simulations to examine how internal tide energy is reduced in the equatorial zone, and determine if this is due to the...
- This $334,378 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) will fund collaborative research to investigate the decay mechanisms of internal tides across the equatorial Pacific and quantify their impact on the regional heat budget. The project will utilize high-resolution numerical ocean simulations to examine internal tide dynamics and their interactions with ocean processes specific to the equatorial zone. The research aims to determine the...
This three-year, $736,628 National Science Foundation project grant will support analysis of oceanographic data from the Indonesian Through Flow region collected during the TRIUMPH field program. The University of Maryland, College Park will examine tidal variability, mixing, and propagation of Kelvin waves on tidal, intraseasonal, and seasonal timescales using seven moorings deployed since fall 2019. This work aims to advance understanding of the role of this shallow choke point in regulating Pacific-Indian Ocean exchange, air-sea interactions, and water-mass transformation. The findings will fill a significant data gap regarding full-depth transport variability, heat and freshwater fluxes, tidal mixing dynamics, and upwelling impacts along the eastern tropical Indian Ocean. The project aligns with the NSF Geosciences program's objective to expand fundamental knowledge of the integrated Earth system through basic research in atmospheric, earth, and ocean sciences.
