Project Title: Epishelf Lakes: A key to understanding ice shelf collapse?

Project Descripton:

In a changing Arctic, once plentiful ice shelves are reducing in both volume and spatial extent. In high melt environments, these ice shelves create a hydraulic control of freshwater overlying seawater which are referred to as epishelf lakes. These lake systems are rare in both the Arctic and the Antarctic and play a key role in ice shelf collapse. We propose to study the epishelf lake in Milne Fiord, the last of its kind in the Canadian Arctic, to discover how these rare stratified water bodies and the ice shelves that retain them disintegrate and relate to wider ice-ocean interactions.
