8 – 21 December 2003 Fortaleza / Brazil and Rio de Janeiro / Brazil The cruise was a German contribution to the CLIVAR programme. The intention was to build upon the data gathered during the World Ocean Circulation Experiment. The spreading of Antarctic Bottom Water in the South Atlantic is seen as an integral limb of the global thermohaline circulation. During the last 30 years, there has been a marked rise in bottom water temperature which is thought to be significantly relevant for climate change. It was the purpose of the cruise to deploy two subsurface moorings at the entrance of the Vema Channel. They are designed to monitor physical property fluctuations during the coming 16 months.
