Popis:	Bulk δ15N values in surface sediment samples off the southwestern coast of Africa were measured to investigate the biogeochemical processes occurring in the water column. Nitrate concentrations and the degree of utilization of the nitrate pool are the predominant controls on sedimentary δ15N in the Benguela Current region. Denitrification does not appear to have had an important effect on the δ15N signal of these sediments and, based on δ15N and δ13C, there is little terrestrial input.
