Deep Sea Drilling Project cores collected at site 362/362A suggest the time of initiation of the Benguela upwelling system off northern Namibia. Studies of sediment accumulation rates, diatom abundances, microfossil temperature preferences (for planktic foraminifers, calcareous nannoplankton, and silicoflagellates), productivity (expressed as the organic carbon content), and phosphorus incorporation in calcareous skeletons all suggest that major, sustained upwelling began in the early late…

Miocene to Pliocene development of surface and subsurface temperatures in the Benguela Current system
[1] The initiation of the Benguela upwelling has been dated to the late Miocene, but estimates of its sea surface temperature evolution are not available. This study presents data from Ocean Drilling
The Angola-Benguela upwelling system : Paleoceanographic synthesis of shipboard results from Leg 175
Thirteen sites were occupied during Ocean Drilling Program Leg 175 along southwestern Africa, starting with the Congo Fan in the north and ending off the Cape of Good Hope. North of the Walvis Ridge,
