ACE is an international research initiative that has grown out of the ANTOSTRAT (ANTarctic Offshore STRATigraphy) project. ANTOSTRAT orginated in 1990 as an offshoot project of the Scientific Committee on Antarctic Research (SCAR) Group of Specialists on the Evolution of Cenozoic Paleoenvironments of the Southern High Latitudes. The ANTOSTRAT program officially came to an end in July 2002. The goal of ACE is to continue the study of Antarctic climate and glacial history through paleoclimate and ice sheet modeling studies, purposefully integrated with geological investigations of the proxy record of ancient Antarctic climates and ice sheets. ACE is now an official SCAR program. A more complete introduction to ACE can be found here.
