Abstract:
Two hydraulic piston cores containing the total Quaternary suite were analyzed quantitatively in their planktonic foraminiferal contents. For the Early Pleistocene, the Caribbean standard zonation (BOLLI & PREMOLI-SILVA) can be adopted and refined by the introduction of an additional subzone at its base (the Globorotalia triangula subzone). Local substages are proposed for the Late Pleistocene because index fossils are missing. The use of the transfer-function technique resulted in paleotemperature and paleosalinity curves with a time resolution of cycles of about 4-68,000 years duration. The Early Pleistocene paleoenvironment is characterized by low oscillations of the surface water temperatures, followed by a distinct cooling trend during the Globorotalia viola subzone, a period of smoothed cycles during the Globorotalia hessi subzone and distinctly developed cycles during the late Pleistocene since the oxygen isotope termination III. Grainsize distribution and several dissolution indices gave evidence for current activities on the top of the Walvis Ridge, where the amount of fine grained components in the sediment is reduced in comparison with that of the flanks.
