| Summary: | The Benguela Current System belongs to the greatest upwelling regions of the world. Due to its high sedimentation rates it represents an excellent climate archive and offers the possibility of paleooceanographic reconstructions.As part of ODP Leg 175, three sites (Sites 1085, 1086, 1087) were drilled in the southern part of the Cape Basin. At two of them downhole logging was carried out. With a maximum depth of 610mbsf the sites span the time period between Holocene and late Miocene (0-15 Ma).The location of the sites were chosen in order to document the history of the Benguela Current and contain information on both, the influence of warm water from the Indian Ocean, brought by the Agulhas Current, as well as incursions of cold Antarctic waters. Beside climate informations (e.g. glacial-interglacial stages) the sites contain records of slumping events.Aim is to extrapolate the informations of the sites spatially by associating the results to seismic data collected in 1996 during the METEOR Cruise M34/1.In this contribution we present a first correlation between the properties of the sites and the seismic profiles. Base for this link are synthetic seismograms, derived from density and P-wave velocity data of the cores and loggins. |
