The Southern Ocean plays a critical role in global climate, absorbing a substantial fraction of anthropogenic CO2 from the atmosphere and controlling the global oceanic distribution of nutrients and carbon. The cold upwelling waters in the Southern Ocean are characterized by low carbonate ion concentrations, making this region particularly vulnerable to acidification in a changing climate. Over the past few decades, increased wind stress and CO2 uptake have altered both the physical circulation and carbon chemistry of the region, and the future is likely to be characterized by further changes.
In this talk, output from an ocean physical-biogeochemical-ecological model will be probed to better understand the response of the Southern Ocean to climate variability and change.
