ObjectivesPrevious work off South West Africa had shown that extremely organic-rich sediments, with relatively high concentrations of certain trace elements, are accumulating on the middle part of the shelf. The objective of the cruise was to sample the sediments, both on the shelf and on the upper slope, for a detailed examination of the organic geochemistry and the association of trace metals and organic matter in these unusual sediments.
