Information - CL31 Cenozoic Antarctic glacial history
Antarctica has supported major ice sheets since its separation from other Gondwanan continents early in the Cenozoic. Variations in the size and extent of these ice sheets resulted in major variations in global climate and ocean circulation. Yet, the paucity of Cenozoic Antarctic outcrops has limited our understanding of the timing and scale of dynamic and stable behaviour of the ice sheets. During the last two decades, studies of sedimentary sequences in outcrop and drillcores 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 and climate from Antarctic and Subantarctic records, from outcrop studies, deep sea drilling, continental margin drilling and seismic investigations. Results from recently developed modeling techniques to investigate the influence of atmosphere, ocean and biosphere on past Antarctic climate are also welcomed.
