The individual transects reflect a compromise between geographic coverage, accessibility, and time constraints. We aim to study specific "end-member" environments, which collectively comprise one of the most active areas of ocean productivity. One of the major goals is to reconstruct the evolution of the Benguela Current system and its relationship with the onset of glacial cycles in the northern hemisphere. Most of the proposed sites are expected to have high sedimentation rates, offering an opportunity to develop detailed paleoceanographic records, and all proposed sites will extend and refine the partial record of the paleoceanographic and paleoclimatic changes for the late Neogene that was provided by Deep Sea Drilling Project Sites 362 and 532. Sediments will be largely diatomaceous and carbonate-rich clays with variable, and occasionally very high organic carbon contents.
