Glaciers 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 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 کاملGLIMS: Progress in mapping the world's glaciers
The system allows users to download their selected glacier data in a choice of formats. The results of a query based on spatial selection (using a mouse) or text-field constraints can be downloaded in any of these formats: ESRI shapefiles, KML (Google Earth), MapInfo, GML (Geography Markup Language) and GMT (Generic Mapping Tools). This "clip-and-ship" function allows users to download only the...
متن کاملIce Cores , High - Mountain Glaciers , and Climate
The near-global retreat of high-mountain glaciers and the shrinkage of ice fields and ice caps and retreat of their associated outlet glaciers are perhaps the most visible evidence for 20th-century climate change and the recent increase in the globally averaged near-surface temperatures of the Earth’s surface. The loss of high-mountain glaciers—including ice fields, ice caps, and other glaciers...
