Record #96620:

Water-pressure dependence of the velocity of Ice Stream B, Antarctica (abstract) / Richard B. Alley, Donald D. Blankenship, S.T. Rooney, Charles R. Bentley.

Title: Water-pressure dependence of the velocity of Ice Stream B, Antarctica (abstract) / Richard B. Alley, Donald D. Blankenship, S.T. Rooney, Charles R. Bentley.
Author(s): Alley, Richard B.
Blankenship, Donald D.
Rooney, S. T.
Bentley, Charles R.
Date: 1989.
Publisher: Cambridge: International Glaciological Society
In: Annals of Glaciology. (1989.), Vol. 12 (1989)
Abstract: Describes water-pressure theory and uses this, together with Weertmann sliding theory, Boulton and Hindmarsh bed-deformation relation, and field data to model ice stream. Results are that water pressure decreases and till softens down-stream, and that sliding between ice and till contributes <10% of total basal velocity. Three papers descibing this work have been submitted to Journal of Glaciology.
