Session Description:
The Southern Ocean, south of 30°S, occupies just under one-third of the surface ocean area, yet it accounts for a disproportionate share of the vertical exchange of heat, carbon and nutrients between the deep ocean, the surface ocean and the atmosphere. Understanding the physical and biogeochemical processes that determine the Southern Ocean’s mean state, variability, and response to external forcing is critical to our understanding of the climate system as a whole, and for reducing uncertainties in climate projections. Recent advances in data collection, state estimation and modeling capabilities have finally established the necessary infrastructure to permit a deeper understanding of the Southern Ocean’s processes that are relevant to climate. Working toward this goal, this session will present new results based on modeling and/or observational efforts that investigate biogeochemical processes, large-scale and mesoscale circulation, mixing, as well as ocean-atmosphere and ocean-ice interactions.
