This National Science Foundation Project Grant of $208,680 will support research into the role of a basal magma ocean in influencing early Earth's magnetic field processes. Awarded on August 15, 2022 to the University of California San Diego's Scripps Institution of Oceanography, with performance through July 31, 2025, the grant is part of NSF's Geosciences program (CFDA 47.050).

The research team will conduct dynamic and static compression experiments to measure physical properties of iron-bearing silicate melts at high pressures and temperatures. They will collect data on iron spin state, melt density, iron partitioning between melt and mantle minerals, and the effect of iron on melting temperatures. Additionally, the team will perform geodynamic modeling incorporating these experimental constraints. The goal is to advance understanding of basal magma ocean dynamics and evolution, and evaluate the hypothesis that such an ocean powered Earth's early magnetic field. Results will provide insight into initial magma ocean depth and duration, and factors controlling magnetic field strength generation within the ocean.
