ANDRILL (ANtarctic geological DRILLing) is a new international, multi-disciplinary drilling program that targets geological records that lie hidden beneath the icy blanket of Antarctica. The primary objective is to investigate Antarctica’s role in global environmental change over the past sixty-fi ve million years, at various scales of age resolution, and thereby enhance our understanding of Antarctica’s potential response to future global changes. Efforts to understand the infl uence of Antarctica on global climate change require a fundamental knowledge of how the Antarctic cryosphere (ice sheets, ice shelves, and sea ice) has evolved, not only in recent times but also during earlier geological periods when global temperature and atmospheric CO2 levels were similar to what might be reached by the end of this century. ANDRILL’s integrated science approach willuse stratigraphic drilling, coring, and multi-proxy core analysis combined with geophysical surveys and numerical modeling to study the Cenozoic history of Antarctic climate and ice sheets, the evolution of polar biota, Antarctic tectonism, and Antarctica’s role in the evolution of Earth’s ocean–climate system.
