The glaciers studied were Petermann Glacier, Helheim Glacier, North-East Greenland Ice Stream and Jakobshavn Glacier.
The EGRIP international project hopes to gain new and fundamental information on ice stream dynamics, thereby improving the understanding of how ice streams will contribute to future sea-level change.
By analysing data from the Greenland GPS Network and satellite data on ice thickness, an international research team found that the Zachariae ice stream has receded by about 20 kilometres in the past decade.
Called the Whillans Ice Stream Subglacial Access Research Drilling (WISSARD) project, it will continue for six years and will study life under the glaciers as well how the glaciers and ice sheet move, how the subglacial water flows, and any implications for climate change.
The existence of the proposed peripheral ice caps--independent from, but abutting against the Lauren-tide Ice Sheet--requires drawdown via an ice stream through the Gulf of St.
The pattern of the glacier crevasses was either regular (controlled by previous ice stream direction) or irregular (uncontrolled by glacial dynamics).
Most of the growth has occurred on Ice Stream C, which became stagnant 150 years ago.
Scientists have had their first inside look at ice layers, frozen debris, and, a surprising channel of water deep beneath an Antarctic ice stream, thanks to an ice probe designed by NASA's Jet Propulsion Laboratory (JPL), Pasadena, Calif.
These images also revealed that a network of ice streams, one ice stream of which is 800-kilometres long and reaches speeds up to one kilometer per year, was transporting close to 80 cubic kilometers of ice into the sea every year.
In contrast, the active lake system of the lower part of Whillans Ice Stream suggests a widespread anomalous mantle heat flux, linked to a rift source," the researchers wrote in the (http://onlinelibrary.
Scientists from the University of Aberdeen and the British Antarctic Survey (BAS) used ice-penetrating radar to build up a picture of the underlying bedrock in the vicinity of one of the ice sheet's many glaciers, the Ferrigno Ice Stream.
