PC34C:
The Role of the Southern Ocean in the Global Carbon Cycle I Posters


Session ID#: 27989

Session Description:
The Southern Ocean is estimated to account for approximately half of the global oceanic sink of anthropogenic carbon, thus playing a key role in the climate system. Changes in the carbon cycle in this region are also thought to exert a strong influence on glacial-interglacial cycles. Recent work has highlighted large interannual variability in the Southern Ocean sink, and new observational estimates of the carbon cycle are emerging from biogeochemical floats and atmospheric measurements. The Southern Ocean remains, however, the basin least constrained by observations, with the largest disagreement among climate models and between models and observations. Changes to our understanding of the Southern Ocean carbon cycle have significant implications for the carbon budgets of the atmosphere and land components of the climate system. We invite abstracts that investigate these topics in both the modern and paleo-climate eras, in particular the magnitude and spatial distribution of the different parts of the Southern Ocean carbon cycle; the variability of the carbon cycle on seasonal to decadal timescales and centennial to glacial-interglacial timescales; and the impact on and interactions with the atmosphere, land, and world ocean.
