The Northern Hemisphere Glaciation modified the global current system leading also to changes in the local current situation in the Cape Basin. This interaction of climate and oceanic currents left a significant imprint in the sedimentary structures along the continental margin of southwestern Africa. Additionally, tectonic movements shaped the sedimentary sequences. To gain an understandig about the influence of the different factors on the build up and composition of the sedimentary layers in the Cape Basin the (a) spatial distribution of seismostratigraphics units (event horizons), (b) physical and chemical properties of sediments at event horizons, and (c) climate information of the hinterland need to be extracted from seismic profiles and sedimentological parameters. The combination of reflection seismic records with drill site information assited by palynological data will provide a comprehensive information of the sedimentary regime in the Cape Basin and elucidates the affect to Initiation of Northern Hemisphere Glaciation to depositional environment even located far away in the South.
