This National Science Foundation (NSF) Geosciences Program (CFDA 47.050) Project Grant award for $1,195,922 will support the University of Washington's research project, "Exploration of Anisotropy and Inhomogeneity of Ocean Boundary Layer Turbulence." The project aims to provide the first direct observational study of the anisotropy and inhomogeneity of ocean surface boundary layer turbulence using custom-built acoustic instruments that drift with the water flow. The observations...
This National Science Foundation (NSF) Geosciences program Project Grant award, with a total funding of $438,734, supports a collaborative research effort to study the turbulence in the stratified layer at the air-water interface caused by waves and wind. The research will be conducted through a combination of controlled laboratory experiments and state-of-the-art numerical simulations, with the goal of improving the representation of the ocean surface boundary layer in Earth-system models....
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 Engineering program (CFDA 47.041) aims to improve the understanding of biogenic turbulence, which refers to the mixing of heat and CO2 in the ocean driven by the motion of small organisms like zooplankton. The $259,994 award, effective from July 1, 2024 to June 30, 2027, will fund a collaborative research project between the University of Pittsburgh and other institutions to investigate the minimum swimmer size required to...
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 $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 federal Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) will support research examining the interactions between internal waves and submesoscale currents in the ocean's bottom boundary layer. The $567,136 award, effective June 1, 2024 through May 31, 2027, will be provided to The Leland Stanford Junior University to conduct theoretical analyses, observational data studies, and computer simulations to assess the impact of these interactions on...
This $340,000 Project Grant award from the National Science Foundation (NSF) Engineering program (CFDA 47.041) supports a collaborative research project at the University of California, Santa Barbara (UCSB) to investigate the minimum size of zooplankton swimmers required to generate sustained biogenic turbulence in the ocean. The research aims to improve understanding of how the motion of small organisms contributes to vertical mixing of heat and CO2 in the ocean, which is crucial for predicting...
This $669,091 Project Grant from the National Science Foundation's Geosciences program (CFDA 47.050) supports collaborative research to estimate global eddy-driven transport using in situ Lagrangian observations. The Planetary Science Institute will use existing particle-based methods and compare them with coherent structure methods to quantitatively assess the impact of long-lived ocean structures on fluid transport. Theiss Research will assist in this effort through intercomparisons of...
This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) provides $1,354,056 to the University of California San Diego Scripps Institution of Oceanography to jointly implement a new measurement technique called distributed acoustic sensing. This technique will generate high-resolution (10 m in space, minutes in time) images of ocean temperature and current velocity fields above a 34-km cable laid on the seafloor off the Azores islands. The goal is to...
