Description
Summary:International audience The Antarctic ice sheet represents a potential contribution to sea level rise. Understanding processes interacting on the ice sheet is fundamental to precisely determine its response to a rapid changing climate and estimate its present and future contribution to sea level change. Satellite altimetry and gravimetry have been providing with maps of spatial and temporal changes of the ice sheet elevation and mass. They reveal that several places in Antarctica are changing at an accelerating rate in response to current climate change. The future monitoring programs of the ice sheet will significantly improve our knowledge of the ice sheet.
