The Geosciences program supports basic research in the earth sciences to strengthen understanding of the integrated Earth system....
- The National Science Foundation Division of Earth Sciences awarded the Smithsonian Institution $354,472 on August 1, 2026, to conduct collaborative research on magma sources and formation through high-pressure and high-temperature laboratory experiments and mathematical modeling. The recipient will use electron microprobe and X-ray absorption near-edge structure (XANES) analyses to measure the oxidation state of iron in peridotite samples and examine how oxygen fugacity varies between...
The National Science Foundation Division of Earth Sciences awarded Woods Hole Oceanographic Institution $485,780 on September 1, 2026, under the Geosciences program to support postdoctoral research on hydrogen cycling through Earth's interior, with particular focus on oceanic volcanic hotspots. The postdoctoral fellow will analyze hydrogen and helium isotopic compositions alongside major, trace, and volatile element concentrations in submarine volcanic glasses and olivine-hosted melt inclusions collected from localities that tap geochemically distinct mantle domains associated with subduction. These melt inclusions represent deeply entrapped melts that retain less degassing than submarine glasses, allowing the fellow to constrain deep cycling of hydrogen through Earth's interior and link elevated helium isotope ratios (³He/⁴He) to specific recycling processes—subduction, core-mantle exchange, diffusion, and degassing. The research will track how subducted hydrogen returns to Earth's surface through volcanic hotspots, providing insights into mantle evolution and long-lived geochemical heterogeneity in the lower mantle. The work will serve the national interest by informing natural resource management through improved understanding of mantle processes and by enhancing the science and technology workforce through high school research opportunities. Performance occurs at Woods Hole, Massachusetts, with a period of performance from September 1, 2026, through August 31, 2028.
