Antarctic Lecture: Dr. Andrew Fountain
April 27, 2021 @ 7:00 pm - 8:00 pm
“Dynamic Antarctica, More Than Just a Slab of Ice”
Dr. Andrew Fountain, Professor of Geography and Geology, Portland State University
Antarctica is a dynamic and, in places, a rapidly changing ice sheet with global implications for sea level rise. Subglacial lakes dot the underside of the ice sheet, some with microbial life, and others filling and draining. Rapid rivers of moving ice drain the ice sheet into the ocean, impeded by ice shelves that, in places, are destabilizing and collapsing. Dr. Fountain’s presentation will discuss the history of our evolving understanding of the ice sheet from an immobile slab of ice to the dynamic and rapidly changing ice sheet that we understand today.
