The marginal shear stress of Ice Stream B , West Antarctica
To ascertain whether the , ·elocity of Ice Stream B, \\'est Antarctica, may be controlled by the stres e in its marginal shear zones \ the .. Snake" and the .. Dragon'· ), we undertook a determination of the marginal hear stress in the Dragon near Camp up B by using ice itself as a stress meter. The ob erved marginal shear strain rate of0.14 a I is used to calculate the marginal shear stress fr...
متن کاملChanges in the Margin of Ice Stream C, Antarctica
We present results from satellite imagery, ice motion surveys, and ice-penetrating radar studies of a portion of the north margin of Ice Stream C, one of the ice streams draining the West Antarctic Ice Sheet to the Ross Embayment. Our studies suggest that the shutdown of Ice Stream C about 150 years ago was not a single event but a sequence involving stagnation of ice and migration of the ice s...
متن کاملTransient slip events from near‐field seismic and geodetic data on a glacier fault, Whillans Ice Plain, West Antarctica
[1] Bidaily, tidally modulated stick‐slip speed‐ups of the Whillans Ice Plain (WIP) provide insight into glacier dynamics and failure at a naturally repeating fault asperity. We installed a network of continuously operating GPS receivers in 2007 and deployed on‐ice broadband seismometers during the austral summer of 2008 on Whillans Ice Stream (WIS), West Antarctica, and recorded 26 glacier spe...
متن کاملNucleation and seismic tremor associated with the glacial earthquakes of Whillans Ice Stream, Antarctica
[1] The ability to monitor transient motion along faults is critical to improving our ability to understand many natural phenomena such as landslides and earthquakes. Here, we usedata from a GPS and seismometer network that were deployed to monitor the regularly repeating glacial earthquakes of Whillans Ice Stream, West Antarctica to show that a unique pattern of precursory slip precedes comple...
متن کاملChanges in west Antarctic ice stream velocities: Observation and analysis
[1] We have produced a map of velocity covering much of the Siple Coast ice streams. The map confirms earlier estimates of deceleration on Whillans Ice Stream. Comparison with bed elevation data indicates that subglacial topography and the location of consolidated sediment play a strong role in determining the location of the tributaries feeding the ice streams. Force balance estimates based on...
