Earth’s Leaky Core: Identifying Signatures of Core Materials in the Lithosphere

Executive Summary

We aim to identify and quantify mass transport between Earth's core and lithosphere, which will allow us to study a fundamental scientific question: How has core-mantle interaction affected, and how may it continue to affect, our atmosphere, biosphere, and lithosphere? The technical competencies developed during this research have significant application to national security missions.
