Rekonstruktion der spaetquartaeren Tiefenwasserzirkulation und Produktivitaet im oestlichen Suedatlantik anhand von benthischen Foraminiferenvergesellschaftungen

Sixty high-quality surface sediment samples and two late Quaternary sediment cores from the eastern South Atlantic Ocean including the Walvis Ridge, the Angola and Cape basins and the Southwest African continental margin were analysed for their benthic foraminiferal content to reconstruct late Quaternary deep water circulation and productivity changes. Live (stained with Rose Bengal) and dead faunas of the surface sediment samples were counted separately. Live and dead faunas, as well as late Quaternary fossil faunas from the sediment cores were grouped into a clear number of principal faunal end-members by Q-mode and R-mode principal component analysis.
