Title: Earth Surface Oxygenation: An Inside Job?
Conveners: Anbar, Bell, McNamara
At its surface, Earth is an oxygenated world. O2 is the 2nd-most abundant atmospheric gas, making metazoan life possible. In contrast, O2 is not found deep beneath Earth's surface, and oxygen is highly depleted in the core. This redox contrast between Earth's surface and depths evolved over time. A major transition occurred 2.4 Ga. This surface evolution was surely shaped, and possibly driven, by changes in Earth's interior, but the connections are not well understood. This session aims to integrate geochemical studies of the lithosphere and mantle with seismic data, geodynamic models, thermodynamic calculations, and mineral physics experiments, to examine the relationship between Earth's surface oxygenation and its internal evolution.
