A fragile balance

The sea encircling Antarctica mixes water from all the ocean basins. This circulating pattern influences the exchange of carbon dioxide (CO2) between the ocean and the atmosphere. A study by an international research team, led by Dr. Torben Struve from the University of Oldenburg, Germany, indicates that the complex equilibrium of water masses reacts sensitively to wind conditions over the Southern Ocean. Future climate change could lead to increased release of CO2, the scientists suggest.
