Abstract: In the last few decades, a great deal of work has been carried out on the nature of the oceanic circulation around southern Africa. Attempts have been made to determine regional ocean-atmosphere interactions and the effect of changing sea-surface temperature fields on weather and climate. At the same time, the marine biology and ecosystems of coastal waters have been extensively studied. Few studies have been concerned with the possible effects of global change on the physical and biological components of the systems and their linkages in the regional earth system of the subcontinent. In this paper, a first attempt is made to integrate past work and synthesize it using a systems approach framework. Attention is focused on the nature of the regional ocean circulations affecting southern Africa. The features of the Agulhas and Benguela systems most likely to be affected by global change are discussed and contrasted. At the same time the links to the marine biological and coastal ecosystems of the east and west coasts are explored and the inter-dependencies between physical, biogeochemical and ecological components of regional ocean systems and their anthropogenic modulation are considered.
