Under this Project Grant, researchers will conduct an observational study during an expedition to the Labrador Sea in fall 2023 to measure bubble-mediated air-sea...
This Project Grant from the National Science Foundation's Division of Ocean Sciences provides $757,404 under the Geosciences program (CFDA 47.050) to the University of California San Diego's Scripps Institution of Oceanography from October 1, 2022 to September 30, 2025. The award will support collaborative experimental and numerical studies of the effects of wind, wave scale, and salinity on bubble entrainment by breaking waves. Researchers will leverage the Scripps Ocean-Atmosphere Research...
The University of Minnesota will receive $446,973 from the National Science Foundation under the Geosciences program (CFDA 47.050) to conduct experimental and numerical studies of bubble entrainment by breaking waves from October 1, 2022 to September 30, 2025. The research aims to advance understanding of the physical processes controlling bubble generation and dispersal in ocean waves and their dependence on factors like wave scale, slope, wind forcing, and salinity. Researchers will leverage...
The National Science Foundation (NSF) awarded a $186,006 Project Grant under the Integrative Activities (CFDA 47.083) program to the University of Louisiana at Lafayette to study methane seepage along the U.S. Atlantic margin. The 3-year project, starting September 1, 2024, will integrate geochemical, microbiological, geophysical, and geological data to investigate the origin, subsurface migration, and methane oxidation processes of these recently discovered seeps. The multidisciplinary research...
This National Science Foundation Project Grant award of $512,542 provides funding from September 1, 2022 through August 31, 2025 to develop an integrated imaging system to concurrently measure characteristics of submarine hydrocarbon seep bubbles and drops and the surrounding ocean water structure under the Geosciences program (CFDA 47.050). The University of Missouri System will receive funding to support research delivering an innovative imaging system that can near-simultaneously measure...
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 $552,775 Project Grant awarded by the National Science Foundation's Geosciences Program (CFDA 47.050) will fund research to investigate benthic iron fluxes in the Labrador Sea, an important region of deep-water formation. The project aims to identify and quantify iron sources from ocean sediments to the overlying surface waters, which can influence the biological carbon pump in this high-latitude region. The research team from Florida State University will collect sediment and pore water...
This $1,038,171 project grant from the National Science Foundation's Geosciences program (CFDA 47.050) supports research into methane efflux from river-influenced coastal marine sediments in the Gulf of Mexico. The Louisiana Universities Marine Consortium will measure methane fluxes from coastal sediments into Gulf waters using an in situ lander to collect benthic flux measurements of oxygen and methane. Sediment microprofiles of oxygen and sulfide will also be analyzed. Naturally occurring...
This $325,003 Project Grant award from the National Science Foundation's Engineering program (CFDA 47.041) supports fundamental research to understand the flow patterns and turbulent structures of bubble plumes. The project aims to develop a comprehensive model of the entrainment process in bubble plumes under different conditions, which could help improve computer simulations of bubble plumes in natural and engineered systems. The research will include laboratory experiments to measure bubble...
