Relation between water input, basal water pressure, and sliding of Columbia Glacier, Alaska, U.S.A. (abstract) / Mark F. Meier.
Title: | Relation between water input, basal water pressure, and sliding of Columbia Glacier, Alaska, U.S.A. (abstract) / Mark F. Meier. |
Author(s): | Meier, Mark F. |
Date: | 1989. |
Publisher: | Cambridge: International Glaciological Society |
In: | Annals of Glaciology. (1989.), Vol. 12 (1989) |
Abstract: | Glacier was drilled at two locations (ice thickness 975 and 560 m) 9 km apart in summer 1987. Fluctuations in basal water pressure, water input as rain or ice melt, and surface-ice velocities were measured at short time intervals continuously during July and August. Results suggest that sliding is not function of just driving stress and effective pressure; amount (thickness and/or areal extent) of water, or possibly rate of change of water input will have to be considered. |
