Group: Summary

   This data set is a collection of video data of basal ice taken in a borehole 
   on the Kamb Ice Stream in West Antarctica. Ice streams are an expression of 
   the inherent instability of the West Antarctic Ice Sheet, and their behavior 
   is a key control on the overall ice-sheet mass balance. Understanding the 
   response of the ice sheet in a warming climate requires a thorough 
   understanding of the internal dynamics of ice streams, in addition to the 
   relevant ice-atmosphere and ice-ocean interactions in the region. The basal 
   environment of the ice streams and of many glaciers is a key scientific 
   interest, including conditions, mainly basal sliding, that lead to fast flow 
   of the ice. The purpose of this data set is to present a review of the full 
   range of original video recordings from the basal ice of the Kamb Ice Stream. 
   Direct observations at the ice-stream bed are a crucial complement to modeling 
   efforts predicting future scenarios in a warming climate.
