Record #84658:

Accelerated ablation at a glacier ice-cliff margin, dry valleys, Antarctica / T.J. Chinn.

Title: Accelerated ablation at a glacier ice-cliff margin, dry valleys, Antarctica / T.J. Chinn.
Author(s): Chinn, T. J.
Date: 1987.
In: Arctic and Alpine Research. (1987.), Vol. 19(1) (1987)
Abstract: Cliffed margins of polar glaciers are important source of meltwater. Because of low sun angles, cliff face receives more solar radiation than does upper glacier surface and so melts faster. Ablation is particularly enhanced and occurs earlier where cliff impinges against steep rock slope. On subdued ice cliffs wich do not calve, differential ablation can form ice terraces, which, in turn, increase ablation by increasing area of ice-cliff faces.
