The National Science Foundation (NSF) Division of Earth Sciences awarded a $307,797 Project Grant to Yale University to conduct experimental research on the mechanical properties of the mineral olivine under deep upper mantle conditions. The goal is to improve understanding of transient creep, plastic anisotropy, and the role of grain-boundary sliding in olivine, which are critical factors governing Earth's mantle dynamics and processes like post-glacial rebound. The 3-year project will...
This two-year, $389,704 National Science Foundation project grant will support the development of a reference model describing the shear-wave velocity structure of oceanic crust and upper mantle for crustal ages of 0 to 9 million years. Funded through NSF's Geosciences program (CFDA 47.050), Woods Hole Oceanographic Institution will leverage 2012 ocean bottom seismometer data collected across the Juan de Fuca tectonic plate to constrain shear-wave velocities through advanced seismic modeling and...
This National Science Foundation project grant award of $249,068 provides funding from February 1, 2022 through January 31, 2025 to support collaborative research understanding the influence of tectonic setting on the depth of magmatic processes in the mid-ocean ridge system. Funded under the Geosciences program (CFDA 47.050), which supports basic research in atmospheric, earth, and ocean sciences to expand fundamental knowledge and understanding of the integrated Earth system, this award will...
This Project Grant award of $236,732 from the National Science Foundation's Geosciences program (CFDA 47.050) supports a collaborative research project to investigate mantle dynamics during the early stages of seafloor spreading in the Atlantic Ocean. The primary goal is to characterize the evolution of oceanic crust and mantle over the first ~50 million years of Atlantic Ocean formation adjacent to the eastern North American margin. The project will conduct a 2D/3D seismic survey to collect...
This $140,967 two-year Project Grant from the National Science Foundation's Geosciences program (CFDA 47.050) will fund research to reevaluate the experimental foundation for rheology models of crust-forming minerals. Principal Investigator Jianbao Korenaga of Yale University will apply statistical methods to obtain new flow laws from existing deformation data for a range of minerals. Undergraduate students will conduct this reanalysis, gaining valuable research experience. The new flow laws...
This five-year, $283,849 National Science Foundation Project Grant under the Geosciences program (CFDA 47.050) will fund research at Brown University to develop a new framework for interpreting mantle deformation through an integrated approach combining theory, experiments, and observations across seismic to convective timescales. Key products include observational work characterizing frequency-dependent upper-mantle dissipation in three locations using seismic and geodetic data; experimental...
The National Science Foundation Division of Ocean Sciences awarded a $405,037 Project Grant to the South Dakota School of Mines and Technology under the Geosciences program (CFDA 47.050) for research from February 1, 2022 to January 31, 2025. The award will support collaborative research to better understand how the depth of magmatic processes in the mid-ocean ridge system varies based on tectonic setting. Researchers will analyze melt inclusions and crystals in ocean floor basalts from a...
This National Science Foundation project grant of $117,832 awarded on July 1, 2022 will support research into the geological processes that have shaped the continental lithosphere beneath New England through time. Funded under the Geosciences program (CFDA 47.050), the investigators from Williams College and research institutions will conduct seismic imaging of the crust and upper mantle using data from deployments of seismometers in New York, Massachusetts, Vermont, New Hampshire and Maine....
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...
The National Science Foundation (NSF) awarded a $385,643 project grant under the Geosciences program (CFDA 47.050) to the University of Vermont & State Agricultural College to investigate magma diversification and mobilization processes in the lower continental crust. The 3-year research project will link field mapping, microstructural analysis, geochemistry, and geochronology to test competing models for how magmas form and are extracted from the deep roots of continental arcs. The...
