The model is driven by sea-level change over the last 40,000 yr in association with assumed changes in the rate of melting beneath ice shelves. Ice growth and decay are characterized by thresholds which separate periods of steady state from periods

The morphology, sediments and processes associated with the construction of a moraine along the western margin of the ice-shelf in George VI Sound, Antarctica, are discussed. A conceptual model of the moraine is developed and may help to explain
