Abstract
We analyse the origin, pathways, and age of the central water masses in the Benguela upwelling system (BUS) and the contribution of the Agulhas leakage to upwelling water masses in a highresolution ocean simulation. The Agulhas Current flows along the east coast of southern Africa transporting warm and saline water southwestward. At the southern tip of the African continent, a small fraction (Agulhas leakage) leaves the Agulhas System and continues westward into the Atlantic Ocean (Gordon, 1986).
