Group: Summary

   The Siple Dome Glaciology and Ice Stream History project was part of Western 
   Divide West Antarctic Ice Cores (WAISCORES), an NSF-funded project to 
   understand the influence of the West Antarctic ice sheet on climate and sea 
   level change. WAISCORES researchers acquired and analyzed ice cores from the 
   Siple Dome, in the Siple Coast region, West Antarctica.

   This project supported glaciological studies of Siple Dome and its 
   surroundings between Ice Streams C and D, via two major goals. First, it 
   sought to characterize the dynamic environment and ice stratigraphy of Siple 
   Dome and its surroundings, with the specific mission of assessing Siple Dome 
   as a potential deep core site; and second, to determine whether the 
   configuration of ice stream flow in the region has changed over time. Both 
   goals are relevant to understanding the dynamics of the West Antarctic Ice 
   Sheet (WAIS), its history, and potential future behavior.

   This project was a collaboration between Saint Olaf College, the University of 
   Washington, and the National Snow and Ice Data Center at the University of 
   Colorado. It included studies of satellite imagery and acquisition and 
   analysis of field data from GPS, firn cores and snow pits, and ground-based 
   ice-penetrating radar.

   Data in this collection were obtained during two Antarctic field seasons in 
   1994–95 and 1996–97. The data set is available via FTP as Microsoft Excel 
   Spreadsheet (.xls) and ASCII tab delimited (.txt) files. Related notes are 
   available as a Microsoft Word (.doc) or text (.txt) file. Related images and 
   charts are available as Graphics Interchange Format (.gif) and Joint 
   Photographic Experts Group (.jpg) files.
