- The National Science Foundation's (NSF) Geosciences Program (CFDA 47.050) awarded a $347,910 Project Grant to Princeton University to investigate how water influenced the formation of the Earth's core in the early stages of the planet's history. The project will use advanced computer simulations and machine learning techniques to model the interactions between metallic fluids and silicate melts under hydrous conditions, providing new insights into how water affected the distribution of key...
- This Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) provides $417,152 to the Carnegie Institution of Washington (doing business as Carnegie Institution for Science) to conduct collaborative research on the distribution and circulation of volatile compounds within the Earth's upper mantle. The three-year project, running from September 2025 to August 2028, will use a combination of electrical impedance spectroscopy and Raman spectroscopy techniques to...
- This $265,048 federal Project Grant award by the National Science Foundation's Geosciences Program (CFDA 47.050) will support research at the University of Texas at Austin to investigate the role of hydrated silica minerals in the Earth's deep mantle and their impact on plate tectonics processes and the global water cycle. The project will measure the sound velocities, water solubility, and phase transitions of stishovite and post-stishovite silica minerals under high pressure-temperature...
- 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,...
- This Project Grant award of $335,489 from the National Science Foundation's Geosciences program (CFDA 47.050) supports collaborative research on depth-dependent decarbonation processes in the Sierra Nevada mountains of California. The research aims to improve understanding of how the interaction between hot magma and the Earth's crust drives metamorphic changes, mineral transformations, and the release of elements like carbon. The project will provide valuable insights into the geochemical...
- This $315,000 Project Grant award from the National Science Foundation's Geosciences Program (CFDA 47.050) aims to take a multidisciplinary approach to better understand the geodynamical landscape of the deep mantle, the region between the Earth's liquid iron core and rocky mantle approximately 3,000 km beneath the surface. The research team at Brown University will utilize observations of global-scale Earth processes, including seismic vibrations and crustal warping, to constrain the density,...
- The National Science Foundation awarded Delaware State University a $672,584 project grant under the Geosciences program (CFDA 47.050) to conduct research titled "Excellence in Research: Effect of Hydration on the Thermo-Elastic Properties of Mantle Minerals and the Geophysical Implications" from June 15, 2021 to May 31, 2024. The Geosciences program seeks to expand fundamental knowledge and understanding of the integrated Earth system through support of basic research in...
This Project Grant award from the National Science Foundation's Geosciences program (CFDA 47.050) will experimentally determine the effects of water content on the electrical conductivity of the mineral bridgmanite under pressures and temperatures corresponding to Earth's lower mantle. The $299,996 award, made on August 1, 2025, will be performed by the University of Hawaii at Manoa. The research aims to improve understanding of Earth's initial formation, internal water distribution, and deep-water cycling processes by providing critical constraints on lower mantle hydration levels. The findings will broadly benefit computational modeling of Earth's interior and advance interdisciplinary knowledge, while also providing valuable research and mentorship opportunities for early career scientists and students.
