Abstract
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 will
use 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.
