Natural variations in the warming and cooling cycles of the Agulhas current core region were revealed from Madagascar corals. The new study was led by The University of Western Australia with contribution from GEOMAR Helmholtz Centre for Ocean Research Kiel.
The Agulhas Current, which flows down the east coast of Africa, is the strongest western boundary current in the Southern Hemisphere. Changes in its strength and the heat it transports are of interest, both on regional and global scales. The current is also the gateway for warm and salty Indian Ocean water that slowly goes up the Atlantic on its way to the far northern Gulf Stream.
