Antarctica

Harwood’s research interests involve the studies of Cenozoic and Cretaceous paleoenvironments and paleoclimates of the southern high latitudes and the Antarctic continent. He says marine diatoms and other siliceous microfossils provide a record of paleoenvironmental climate change and marine productive, reflecting large-scale changes in the Antarctic ice sheet, sea ice and paleooceanographic conditions in the Southern Ocean. He serves as research director for the Andrill Science Management Office, which is the center of international and U.S. science efforts to better understand the history of past ice sheet behavior as a guide to future ice sheet response to elevated global temperatures.
