Purpose
Abstract The primary focus of M48 was to investigate the high organic productivity in the upwelling region off Namibia and its impact on numerous pelagic and benthic processes. The third leg studied the integration of the Angola and Benguela current into the circulation system of the South East Atlantic with emphasis on the coupling of the different current branches by the Angola gyre and their response to the wind field. For all benthic surveying activities the mapping with HYDROSWEEP and PARASOUND was an indispensable prerequisite in order to have information for reproducible sampling. Though multibeam data was recorded, it was not the main focus of the cruise and no further information have been provided by the responsible party.
