Journal ArticleDOI
Satellite Radar Interferometry for Monitoring Ice Sheet Motion: Application to an Antarctic Ice Stream
TL;DR: The combined use of SRI and other satellite methods is expected to provide data that will enhance the understanding of ice stream mechanics and help make possible the prediction of ice sheet behavior.
Journal ArticleDOI
Glacier surge mechanism based on linked cavity configuration of the basal water conduit system
TL;DR: In this article, a model of the surge mechanism is developed in terms of a transition from the normal tunnel configuration of the basal water conduit system to a linked cavity configuration that tends to restrict the flow of water, resulting in increased basal water pressures that cause rapid basal sliding.
Journal ArticleDOI
Glacier surge mechanism: 1982-1983 surge of variegated glacier, alaska.

TL;DR: The behavior of the glacier in surge has many remarkable features, which can provide clues to a detailed theory of the surging process and is akin to a proposed mechanism of overthrust faulting.
Journal ArticleDOI
Physical Conditions at the Base of a Fast Moving Antarctic Ice Stream
TL;DR: Boreholes drilled to the bottom of ice stream B in the West Antarctic Ice Sheet reveal that the base of the ice stream is at the melting point and the basal water pressure is within about 1.6 bars of theIce overburden pressure, allowing the rapid ice streaming motion to occur by basal sliding or by shear deformation of unconsolidated sediments.
Journal ArticleDOI
Rheological nonlinearity and flow instability in the deforming bed mechanism of ice stream motion
TL;DR: In this article, the deforming bed mechanism for the rapid motion of Antarctic ice streams is shown to be highly nonlinear, according to information from soil mechanics and preliminary experiments on till from the base of Ice Stream B. The analysis is approximate and some of the system parameters are poorly known.
