Group: Summary

   This data set contains radar internal layer and ice sheet topography data for 
   two sites in Antarctica, along with associated model results from two studies. 
   This project used geophysical inverse theory and a 2.5 D flowband ice-flow 
   forward model to extract robust transient accumulation patterns from multiple 
   deeper layers. Histories of divide migration, or the movement of the ice sheet 
   and ice-surface evolution are also provided. The data used to solve the 
   inverse problem, and the model solutions are provided. Internal layers, modern 
   ice-surface velocities, and modern ice-sheet geometry at Taylor Mouth are 
   available, as well as the pattern of accumulation inferred by Waddington et 
   al. (2007).

   Data are available via FTP in Matlab (.mat) format. Supporting information is 
   available as text files (.rtf and .txt).
