- 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...
- The University of Washington was awarded a $132,500 Project Grant from the National Science Foundation Division of Ocean Sciences under the Geosciences federal grant program (CFDA #47.050). The grant funded a one-year project to test distributed acoustic sensing on the Ocean Observatories Initiative regional cabled array. The goal was to strengthen understanding of integrated Earth systems through basic research supporting atmospheric, earth, and ocean sciences as outlined in the Geosciences...
- 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...
- The National Science Foundation awarded a two-year, $174,000 Project Grant to researchers at Riverside, California under the Geosciences program (CFDA 47.050). The grant will support work using distributed acoustic sensing to detect tremors and characterize earthquake hazard sites in the Cascadia region. Through June 2022 to May 2024, the grantees will evaluate earthquake risks by deploying fiber optic cables to monitor seismic activity. Insights gained from this work will further the...
- This National Science Foundation (NSF) Project Grant award under CFDA 47.050 Geosciences Program provides $227,183 to the University of Kansas Center for Research Inc. to extend the deployment of seafloor optical fiber strainmeters off the coast of Oregon. This two-year project aims to capture additional offshore slow slip events in the Cascadia subduction zone to better understand the timing and mechanics of slip in the shallow and deep portions of the plate interface. The results could improve...
- 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 National Science Foundation (NSF) Project Grant award under the Geosciences program (CFDA 47.050) provides $555,000 to the University of California San Diego (UCSD) Scripps Institution of Oceanography to extend the deployment of seafloor optical fiber strainmeters off the coast of Oregon. The goal is to capture additional offshore slow slip events in the Cascadia subduction zone and better understand the timing and mechanical linkage between shallow and deep slow slip zones. This two-year...
- This $249,924 Project Grant from the National Science Foundation's Geosciences program (CFDA 47.050) supports the development of a long-lived, continuously operating seafloor geodesy reference station capable of operating in deep water. The grantee, Princeton University, will investigate using acoustic signals that only need to travel from the sea surface to the seafloor, removing the prior 3,000 meter depth limitation of existing seafloor geodesy techniques. This new approach involves...
- This National Science Foundation (NSF) Geosciences (CFDA 47.050) Project Grant of $195,406 awarded to the University of Washington aims to develop CALANOID, a modular, low-cost, air-deployable ocean profiling float system. The project seeks to advance the state of the art in ocean sensing technology by designing and validating a scalable profiling platform to capture high-resolution submesoscale ocean dynamics data. Key innovations include a compact buoyancy engine and a miniaturized,...
The National Science Foundation (NSF) awarded a $880,490 Project Grant under the Geosciences program (CFDA 47.050) to the University of Washington (UW) to test a new type of distributed acoustic sensing technology. The project aims to extend the range of this technology, which can detect signals such as earthquakes, ocean waves, whale songs, and ship movements, by enabling it to operate across the optical repeaters of submarine telecommunications cables. Over 3 months, the project will collect data on the NSF's Ocean Observatories Initiative (OOI) Cabled Observatory off the coast of Oregon and compare the results to traditional distributed acoustic sensing and conventional sensors. This technology has the potential to contribute to earthquake early warning, tsunami detection, and marine ecosystem monitoring. The project will also support a graduate student and postdoctoral researcher.
