| Summary: | The Ocean Drilling Program Leg 188 Site 1165 was drilled on the Wild Drift on the Continental Rise off Prydz Bay, East Antarctica to a total depth of 999.1 meters below seafloor (mbsf). It recovered an extensive suite of terrigenous and hemipelagic sediments of early Miocene to Pleistocene age. Of special interest in this study is the sediment column between 0 and 50 mbsf, which consists of a well-preserved section of Pliocene-Pleistocene-age sediments that was sampled at 10-cm intervals. Multiproxy study of this interval could show possible intervals of expansions of the ice-sheet across the continental shelves and express the climatic evolution in Antarctica, particularly during the 'middle' Pliocene warm period (3.15 to 2.85 Ma) which may provide an indication of how the Earth responds to a rise of its surface temperature.According to the existing age model, the upper 50 mbsf stratigraphic sequence of Site 1165 reaches back to ~4.9 Ma. Throughout this interval, the clay-mineral content is characterized by ... : Supplement to: Junttila, Juho; Ruikka, Marttiina; Strand, Kari O (2005): Clay-mineral assemblages in high-resolution Plio-Pleistocene interval at ODP Site 1165, Prydz Bay, Antarctica.
