Antarctica has supported major ice sheets since the Early Cenozoic. Variations in the size and extent of these ice sheets resulted in major variations in global climate, sea-level, and atmospheric/ocean circulation. Yet, there is a paucity of Cenozoic Antarctic outcrops and difficult access to stratigraphic records has limited understanding of the timing and scale of dynamic and stable behaviour of the ice sheets. During the last two decades, studies of long sedimentary sequences drilled in and around Antarctica have led to significant advances in the understanding of the evolution of the Cenozoic climate, oceanography, and biota of the Antarctic continent and the Southern Ocean. This session is designed to investigate the many orders and scales of variation of Antarctica ice sheets, climate and paleobiota from Antarctic and Subantarctic records, deep sea drilling, continental margin drilling and seismic investigations. The session is a contribution to the Antarctic Climate Evolution (ACE) SCAR program, whose goal is to integrate geological data within climate and ice sheet models.
