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...
This $654,897 Project Grant from the National Science Foundation Division of Ocean Sciences, under the Geosciences program (CFDA 47.050), will fund collaborative research on swash zone dynamics driven by obliquely incident waves. The University of Delaware will lead laboratory experiments, theoretical analysis, and numerical simulations to expand understanding of three-dimensional flow and sediment transport patterns in the swash zone under a range of wave conditions and angles of incidence....
This Project Grant from the National Science Foundation's Division of Ocean Sciences, under the Geosciences program (CFDA 47.050), provides $109,068 to the University of Washington from February 1, 2022 to January 31, 2023. The funding supports a collaborative research effort to test the feasibility of making undersea observations of seismic and oceanic processes across ocean basins using existing telecommunications cables. Specifically, the grant will partially fund two graduate students...
This National Science Foundation (NSF) Project Grant, awarded under the Geosciences Program (CFDA 47.050), will support collaborative research to transform the understanding of how coastlines respond to shifts in storm climate patterns. The $893,081 award to Duke University, with a project period from August 2024 to July 2027, will develop new approaches to downscale global climate model outputs to forecast the waves and winds affecting specific coastlines, such as the Carolina coastline. This...
This Project Grant award from the National Science Foundation Division of Ocean Sciences totals $137,255 to support the development of a plate-scale distributed strain sensing system as a candidate for earthquake early warning. Funded under the Geosciences program (CFDA 47.050), the University of California San Diego Scripps Institution of Oceanography will use the award period from October 1, 2022 to September 30, 2023 to establish the feasibility of measuring seafloor deformation along...
This Project Grant from the National Science Foundation Division of Ocean Sciences provides $298,389 to the University of Kansas Center for Research Inc. for research titled "Collaborative Research: Deployment of Seafloor Optical Fiber Strainmeters for the Detection of Slow Slip Events" from February 15, 2021 through May 31, 2024. The funding supports the placement of seafloor optical fiber strainmeters to monitor slow slip events along subduction zones. This work aligns with the goals...
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) 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 Project Grant from the National Science Foundation's Geosciences program (CFDA 47.050) provides $218,998 to North Carolina State University from March 2023 through February 2026. The funding supports research to develop and test a new technique for forecasting geohazards such as landslides, submarine slides, ground fissures, and liquefaction. Specifically, the researchers aim to determine if measurements of the density of excited vibrational modes (DOM) in natural sediments can provide a...
The National Science Foundation (NSF) awarded a $198,069 Project Grant to the University of Washington (UW) under the Geosciences program (CFDA 47.050) to conduct a 4-day test of Distributed Acoustic Sensing (DAS) on the Ocean Observatory Initiative's Regional Cabled Array off the coast of Oregon. The project aims to demonstrate the feasibility of using multiplexed DAS technology on existing submarine telecommunications cables to improve seafloor monitoring capabilities, particularly for...
