This three-year, $641,214 National Science Foundation Project Grant will fund research at Woods Hole Oceanographic Institution to better understand the strength of the oceanic lower crust through experimental and microstructural analysis. Specifically, the awardee will perform high-temperature, high-pressure deformation experiments on plagioclase and clinopyroxene mineral aggregates using a triaxial apparatus. The deformed samples will then be analyzed via electron backscatter diffraction to...
This Project Grant from the National Science Foundation Division of Ocean Sciences, under the Geosciences federal grant program (CFDA 47.050), provides $479,989 to Woods Hole Oceanographic Institution to analyze marine seismic data along the Cascadia subduction zone offshore Vancouver Island to southern Oregon. The award aims to constrain variability in subducting sediment thickness, water content of the downgoing plate, and topography of the sediment-basement interface from January 1, 2023...
The Woods Hole Oceanographic Institution was awarded a $364,098 Project Grant from the National Science Foundation Division of Ocean Sciences on September 15, 2021 to complete the project by August 31, 2024. The grant was awarded under the NSF's Geosciences program (CFDA 47.050), which supports basic research to strengthen understanding of the integrated Earth system.
Specifically, the grant will fund collaborative research to elucidate brine-dominated, segment-scale hydrothermal discharge...
This National Science Foundation (NSF) Project Grant award under the Geosciences Program (CFDA 47.050) provides $236,732 to Louisiana State University to conduct a seismic experiment investigating the early stages of seafloor spreading in the Atlantic Ocean. The project aims to collect new 2D/3D marine seismic data along the eastern North American margin to study the evolution of oceanic crust and mantle during the first ~50 million years of Atlantic Ocean formation. The seismic data will...
This two-year Project Grant from the National Science Foundation's Division of Earth Sciences, under the Geosciences program (CFDA 47.050), provides $167,774 to the University of Houston to investigate mantle dynamics in the Pacific Northwest through 3D anisotropic seismic velocity modeling. The University will use surface wave tomography to construct a high-resolution model of seismic anisotropy in the region, revealing detailed mantle processes and testing mechanisms for geophysical...
The National Science Foundation awarded a $6.5 million Project Grant to the Woods Hole Oceanographic Institution under the Geosciences program (CFDA 47.050) to design and construct a new generation of ocean-bottom seismographs for the U.S. academic community from October 1, 2021 to September 30, 2024. The Geosciences program aims to expand fundamental knowledge of the integrated Earth system through basic research support. Under this award, Woods Hole will deliver new ocean-bottom...
This $249,414 federal Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) will support a collaborative research project to conduct seismic reflection imaging of volcanic cycles at the East Pacific Rise. The primary awardee, Woods Hole Oceanographic Institution, will repeat a 3D multichannel seismic survey conducted in 2008 to investigate how the magmatic and hydrothermal systems beneath the seafloor have changed over the past decade. The time-lapse...
This $228,331 National Science Foundation project grant supports collaborative research to understand the evolution of continental lithosphere beneath New England through geologic time. Funded under the Geosciences program (CFDA 47.050), the research team will employ seismic imaging techniques and analyze geologic structures exposed at the surface to illuminate plate tectonic processes that have shaped the region. Specifically, the investigators from the University of Vermont and partner...
This three-year, $177,799 National Science Foundation Project Grant through the Geosciences program (CFDA 47.050) will fund research to advance understanding of glacial-age western North Atlantic hydrography. The Woods Hole Oceanographic Institution will synthesize existing sediment property data from 30% more deep-sea sediment cores collected between 1994 and 2021. Isotopic and radiocarbon analyses of microfossils from cores spanning the upper 2 km of the region will provide new insights...
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...
