Graeme MacGilchrist. Reframing the carbon cycle of the subpolar Southern Ocean.

Graeme MacGilchrist (University of Princeton). Reframing the carbon cycle of the subpolar Southern Ocean. Global climate is critically sensitive to physical and biogeochemical dynamics in the subpolar Southern Ocean, since this is where the deepest, most carbon-rich layers of the world ocean outcrop and exchange carbon with the atmosphere. Here, we show that the conventional framework for the subpolar Southern Ocean carbon cycle, which attributes a dominant role to the vertical overturning circulation and shelf-sea processes, fundamentally misrepresents regional carbon...
