At this very moment, the ice sheets covering and surrounding Antarctica are dynamic, moving and receding in response to temperature and other factors. Some of the changes are abrupt and quite apparent, like calving events where large chunks of ice break off of glaciers and plunge into the ocean. Others are more subtle because the movement of the ice is occurring slowly, like it has done for over thousands of years. Dr. Phil Bart, LSU College of Science Geology & Geophysics professor, invites us to learn about the evolution of Antarctic ice sheets and how he investigates the movement of ice sheets and ice rises over geologic time to aid in predicting their future behavior.
