Abstract

The IODP Expedition 382 (March-May 2019) focused on the study of the climatic history of the Antarctic Ice Sheet, the chronologic correlation with dust, the implications for sea level, the changes in water masses and thermal forcing, the pro- venance of iceberg rafted debris, the changes in sea ice and the climatic cyclicity and its causes during the Pliocene-Pleisto- cene (Weber et al., 2019). Two sites were drilled in the Falkland-Malvinas contouritic drift and three sites in Pirie and Dove Basins in the South Scotia Sea. About 2800 m of sediment were recovered, with an age from Miocene to present. This work will investigate the physical properties in combination with grain size and element composition (XRF) analyses and X-Ray images to reconstruct the geodynamic and paleoceanographic history of the Southern Ocean based on the characterization of seismic unconformities identified in multichannel and parametric sounder profiles.
