The National Science Foundation awarded a $368,201 Project Grant to the Regents of the University of Minnesota under the Geosciences program (CFDA 47.050) to conduct collaborative research towards developing a new framework for interpreting mantle deformation. Over the five-year period from September 2022 to August 2027, key products and services will include integrating observational, experimental, and modeling efforts to characterize the full-spectrum rheological response of Earth's mantle and...
The Regents of the University of Minnesota received a two-year, $228,130 project grant from the National Science Foundation Division of Earth Sciences to support research entitled "Untangling the Roles of Viscous, Elastic, and Plastic Deformation in Slab Bending." This grant was awarded under the NSF's Geosciences program (CFDA 47.050), which aims to expand fundamental knowledge and understanding of Earth's integrated system through basic research in atmospheric, earth, and ocean...
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...
This three-year project grant from the National Science Foundation Division of Ocean Sciences, under the Geosciences federal grant program (CFDA 47.050), provides $290,762 to Northern Arizona University to develop a new methodology for improving the analysis of shear-wave splitting using ocean bottom seismometers. The methodology aims to address key challenges with traditional approaches to studying shear-wave splitting in complex oceanic environments, including depth-varying anisotropy and...
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 Project Grant award of $320,192 from the National Science Foundation's Geosciences Program (CFDA 47.050) supports fundamental research at the University of Washington to investigate the relationship between metamorphic dehydration reactions in subducting oceanic crust and the occurrence of deep slow slip earthquakes in subduction zones. The research aims to provide geologic evidence for the hypothesized role of fluid production from these reactions in generating the high pore fluid...
This five-year, $252,329 National Science Foundation project grant funds research towards developing a new framework for interpreting mantle deformation. The grantee, the University of California Santa Barbara under the NSF's Geosciences program (CFDA 47.050), will integrate theory, experiments, and observations spanning seismic to convective timescales. Researchers will characterize frequency-dependent upper-mantle dissipation in three locations using seismic and geodetic observations....
