Oceans play a fundamental role in Earth’s climate through their capacity to absorb and store atmospheric carbon. However, temperature-sensitive physical and biological feedbacks generate uncertainty in both the magnitude and persistence of this response, complicating predictions of the long-term fate of anthropogenic carbon dioxide.

Using the Pliocene as an analog for a warm climate state comparable to today, my work investigates two key controls on ocean carbon storage: overturning circulation and temperature-dependent remineralization. Integrating simulations from the Community Earth System Model (CESM) with geochemical reconstructions of water-column δ¹³C and δ¹¹B-derived pH from planktic foraminifera, my research aims to disentangle the roles of these mechanisms in regulating carbon export and storage.
