Research Brief: Seasonal and Interannual Variability of the Weddell Gyre

The Weddell Gyre, located east of the Antarctic Peninsula, is one of the largest features of the ocean circulation of the Southern Hemisphere. A deeper understanding of the dynamics in this remote region will shed light on the role of the gyre in our present climate and help us understand its potential evolution with climate change.

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...
