Mass balance of polar ice sheets.
Recent advances in the determination of the mass balance of polar ice sheets show that the Greenland Ice Sheet is losing mass by near-coastal thinning, and that the West Antarctic Ice Sheet, with thickening in the west and thinning in the north, is probably thinning overall. The mass imbalance of the East Antarctic Ice Sheet is likely to be small, but even its sign cannot yet be determined. Lar...
متن کاملThe Motion of Ice Sheets and Glaciers
The distribution of velocity along a vertical line in Greenland is calculated. Almost all the relative shear motion is concentrated at and very near to the bottom, and this result is thought to apply generally in Greenland and Antarctica. It is due to the relatively high temperature of the lowest layers and the strong dependence of creep rate on temperature. The outward velocity being thus almo...
متن کاملModels for polythermal ice sheets and glaciers
Polythermal ice sheets and glaciers contain both cold ice and temperate ice. We present two new models to describe the temperature and water content of such ice masses, accounting for the possibility of gravityand pressure-driven water drainage according to Darcy’s law. Both models are based on the principle of energy conservation; one additionally invokes the theory of viscous compaction to ca...
متن کاملGlaciers and Ice Sheets Mapping Orbiter Concept
We describe a concept for a spaceborne radar system designed to measure the surface and basal topography of terrestrial ice sheets and to determine the physical properties of the glacier bed. Our primary objective is to develop this new technology for obtaining spaceborne estimates of the thickness of the polar ice sheets with an ultimate goal of providing essential information to modelers esti...
متن کاملConduit Pressure Beneath Glaciers and Ice Sheets
The resistance to sliding beneath soft-bedded glaciers de5 pends on the effective stress N , which is controlled by the subglacial hy6 drological system. While large-scale water transport is primarily through 7 conduits, the effective stress profile beneath most of the glacier base is 8 expected to be controlled by seepage flows through the permeable sed9 iments. Models of the response to force...
