Towards an understanding of the biological forcing of CO2 in the Southern Polar Ocean.

• The aim of this project was to quantitatively investigate the mechanisms driving the oceanic carbon dioxide system and the CO2 air-sea flux in areas of different characteristics regarding water column stratification, ice cover/extent and freshwater input in the Pacific sector of the Southern Ocean. The biogeochemical transformation of carbon was evaluated from CO2 system data and information on water mass properties in the water column. Another goal was to investigate the large natural variability of the marine carbonate system in the study area, to provide basic information needed to predict the response to future changes in the CaCO3 saturation in the Southern Ocean due to changes in sea ice extent and temperature.
