Ocean eddies in the South Atlantic.

The area south of Africa is particularly interesting to oceanographers. In this area, warm, less saline water from the Indian basin encounters the cooler, saltier water of the Atlantic. Rings and filaments of Indian Ocean water periodically enter the Atlantic via the Agulhas Current which flows to the southwest along the southeastern coast of southern Africa.
The input of Indian Ocean water in to the South Atlantic may be important to ocean circulation and dynamics within the Atlantic basin, and to the circulation of saline water in the oceans as a whole.
Indian Ocean water (warm, high sea level) enters the South Atlantic in filaments and rings south of Africa. These features migrate into the South Atlantic Ocean, where they alter the heat and salt balance of the surrounding water. The exchange of water between the Indian and Atlantic basins at their boundary south of Africa is currently being studied within a project called 'Agulhas-South Atlantic Thermohaline Transport Experiment' (ASTTEX).
