Changing Ice Sheets: What is the Evidence? What Next?
Tuesday November 30th
Room 417 Schermerhorn Hall
Summary: The media is full of images of building sized fragments of ice crashing into the ocean and state size pieces of floating ice breaking up in a matter of weeks. Are these monster ice cubes important? Here we will review the evidence for the ice sheet changing beyond the images. The three prominent observations are the edges of the ice sheets are dropping, the flow of ice is speeding up and measurments of the ice sheet mass indicate they are loosing mass. We talk about the work being done at Lamont to understand why the ice sheets are changing. Without understanding why we cannot plan for future change.
Robin Bell is a Lamont Research Professor with the Palisades Geophysical Institute at Lamont-Doherty Earth Observatory. Robin research examines linkages between ice sheet processes and subglacial geology, the interaction of ecosystems and geologic systems from microbes to benthic habitats within the Hudson River, and tectonic uplift and feedback mechanisms.
Robin completed her B.A. in Geology at Middlebury College in Vermont, and her Ph.D. at Columbia University.
Future talks are scheduled for Tuesdays from 12:15-1:00pm in Room 417 Schermerhorn Hall. Attendees are welcome to bring their lunch.
All are welcome to attend!
