Record #112494:

Sedimentary processes may cause fluctuations of tidewater glaciers / Richard B. Alley.

Title: Sedimentary processes may cause fluctuations of tidewater glaciers / Richard B. Alley.
Author(s): Alley, Richard B.
Date: 1991.
In: Annals of Glaciology. (1991.), Vol. 15 (1991)
Abstract: Temperate glacier ending in water advances by depositing moraine shoal, which "dams" tidewater calving, and recycling this shoal in conveyer-belt fashion. Simple model suggests that conveyer-belt recycling of shoal must continue until calving stops and all ice flux is removed by surface ablation, or until glacier retreats rapidly from shoal; retreat can occur without external forcing if glacier advances into deepening water and if sediment recycling is rapid compared to supply of new sediment to moraine shoal.
