David Harwood University of Nebraska-Lincoln "The history of Antarctica is not yet known," says David Harwood, Professor of Geosciences at the University of Nebraska-Lincoln. "What lies beneath has not been identified." But Harwood and a team of 80 to 100 scientists from around the world have begun to discover much more about its past with the Antarctic DRILLing program (ANDRILL). With two seasons of successful drilling now completed, ANDRILL has reached down more than 1,285 meters, and more than 17 million years back in time. "The chief objective of this multinational collaboration is to recover a history of paleoenvironmental changes that will guide our understanding of how fast, how large, and how frequent were glacial and interglacial changes in the Antarctica region. Future scenarios of global warming require guidance and constraint from past history that will reveal potential timing frequency and site of future changes."
