ON THE OCCURRENCE OF OXYGEN-DEPLETED WATER SOUTH OF AFRICA AND ITS IMPLICATIONS FOR AGULHAS-ATLANTIC MIXING uri icon

abstract

  • Data obtained during the Agulhas Retroflection cruise of the Knorr in November/December 1983 suggested the presence of an oxygen-depleted water layer at the boundary of the Agulhas Current/Return Current system. An analysis of historical data shows that such a layer is present off the edge of the Agulhas Bank during much of the year and may be found off the West Coast as far north as 32S during summer. The origins, temporal and spatial variations and hydrography of this low-oxygen water mass are described, and its influence on the biology of the Western Cape upwelling region is discussed. It is considered that the presence of this low-oxygen water mass can be used to show penetration of Agulhas water into the South-East Atlantic. 1988 Taylor & Francis Group, LLC.
