| 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. |
