This $355,607 Project Grant award from the National Science Foundation (NSF) Division of Earth Sciences under the Geosciences program (CFDA 47.050) supports collaborative research to investigate an ancient example of flat-slab subduction in southern California and western Arizona. The goal is to collect data from rocks that were once located above the descending oceanic plate in order to improve simulations and understanding of similar modern tectonic settings, many of which pose significant...
This three-year, $432,521 National Science Foundation project grant supports research investigating the formation of stagnant slabs and implications for subduction dynamics. Funded under the Geosciences program, which supports basic research expanding understanding of the integrated Earth system, the award supports collaborative modeling and seismic tomography work by researchers at Princeton University. Specifically, the researchers will explore how subducted tectonic plates become trapped in...
This $393,670 National Science Foundation award under the Geosciences program (CFDA 47.050) funds research at the University of California, Davis from March 2022 through February 2025 to test the role of metastable olivine in subduction dynamics and deep earthquakes. The researchers will use state-of-the-art numerical simulations integrating experimental and observational parameters to model various subduction scenarios with and without the presence of metastable olivine. They will compare model...
This National Science Foundation project grant of $249,976 supports research at Arizona State University from August 2022 through July 2025 under the Geosciences program (CFDA 47.050). The award will fund collaborative research between experimental mineral physics and computational geodynamics to advance understanding of deep Earth processes through three key pieces. First, dynamic compression experiments will measure the spin state and structure of dense iron-bearing silicate melts. Second,...
The National Science Foundation awarded a $447,680 Project Grant to the University of California, Berkeley under the Geosciences program (CFDA 47.050) to support a multi-disciplinary investigation of slab deformation and resulting seismic anisotropy from the transition zone to the base of the mantle. The three-year project beginning July 1, 2021 will utilize Berkeley's expertise in geophysics, seismology and geodynamics to advance fundamental understanding of integrated Earth system processes...
This $228,014 Project Grant award from the National Science Foundation's Geosciences program (CFDA 47.050) will support research to improve understanding of the Earth's mantle anelasticity. The project aims to analyze seismic wave amplitudes to better constrain the radial attenuation structure of the mantle, which is crucial for understanding the material properties, thermal structure, and dynamics of the Earth's interior. The research activities will create a new global dataset and 1-D...
This $174,000 two-year project grant from the National Science Foundation Division of Earth Sciences aims to advance understanding of episodic tremor and slip in subduction zones. Funded under the Geosciences program (CFDA 47.050), which supports basic research to strengthen knowledge of the integrated Earth system, this award will fund research into the role of metasomatic alteration in subduction zone seismic phenomena from September 2021 through August 2023. The grantee, located in Seattle,...
The National Science Foundation awarded a $174,000 two-year Project Grant to researchers at the University of Colorado Boulder under the Geosciences program (CFDA 47.050). The grant will fund a research project to Quantify Scale of Lower Crust and Mantle Heterogeneities Beneath the Continental United States through Bridging Seismology, Mineral Physics, Petrology, and Magnetotellurics. The Geosciences program supports basic research to strengthen understanding of Earth's integrated system. This...
This National Science Foundation (NSF) Geosciences Program (CFDA 47.050) Project Grant award totaling $567,283 provides funding to the University of Arizona (Arizona Board of Regents) from August 1, 2024 to July 31, 2027 to study the fate of subducted carbonate platforms in the Earth's sub-arc mantle. The key objectives are to: Obtain geochemical and isotopic data on subducted marbles to identify potential signatures in arc volcanic rocks, indicating the source of the subducted carbon. Conduct...
The National Science Foundation Division of Earth Sciences awarded Saint Louis University a $243,553 project grant under the Geosciences program (CFDA 47.050) to characterize the oceanic lithosphere-asthenosphere boundary in the Colombian subduction zone through receiver function analysis. The two-year award beginning August 1, 2021 will support the University's efforts to strengthen fundamental knowledge and understanding of the integrated Earth system through basic research of the atmospheric,...
