Understanding ice stream dynamics over decadal to millennial timescales is crucial for improving numerical model projections of ice sheet behaviour and future ice loss. In marine-terminating settings, ice shelves play a critical role in controlling i... Read More about The geomorphological record of an ice stream to ice shelf transition in Northeast Greenland.
