Processes in northern polar sea and southern ocean

Polar regions import heat from the mid-latitudes via ocean currents, which have a negative influence on the sea ice cover. Around Antarctica and Greenland, ocean currents interact with the continental ice sheets.

The polar oceans play a vital role for the global large-scale flow field by ventilating the deep oceans.

We explore the importance of physical processes in the Arctic and Antarctic Oceans for a changing climate and the polar ecosystems.
