Abstract
Paul Karrow began a series of discussion papers on the identification and meaning of carbonate dispersal train in the southern Laurentide Ice sheet (LIS). This presentation focuses on carbonate dispersal in the NE sector of the LIS, on Melville Peninsula, Baffin Island, and Hudson Strait. The northern Melville dispersal train is distinctive in that there are sharply defined plumes within the main train. Carbonate dispersal trains are related to late-glacial calving sites at the ice front, with ice streaming characterized by intermittent gliding and deformation at the glacier bed. For the Foxe Ice Centre, the streaming events caused an abrupt collapse of the ice mass in Foxe Basin, about 6800 BP, and a shift to land-based flow centres on Baffin Island and Melville Peninsula.
