Özet

This work presents the results of the research project WISE (West Antarctic Ice Sheet Evolution) the main aim of which is to provide new insights about WAIS (West Antarctic Ice Sheet) evolution in the Eastern Ross Sea (Antarctica) since the late Miocene times, from morphological and geophysical analysis of glacial sediments. A square grid of 1230 km high-resolution multi-channel seismic reflection data, multi-beam bathymetry data and nine Sound Velocity Profiles (SVP) were collected in January 2006 from the northwestern sector of the Glomar Challenger Basin (Eastern Ross Sea), and tied to Deep Sea Drilling Program site 271.
