Oceanography
The Weddell Sea is one of the few areas where deep and bottom water masses are formed to contribute to the global thermohaline circulation.
This circulation has been proven difficult to quantify because the Geopotential surface heights above the 100dB level show only very weak surface currents. Assisted by the CTDs that can sample to depths in excess of 10,000 metres, our oceanographers hope to quantify the volume transported and determine the deep convective circulation in all areas of the Weddell Sea.
