Group: Summary

   This data set characterizes the microstructure in ice cores, in particular the 
   microstructural locations of impurities, grain orientations, and strain 
   gradients. The fabric of polycrystalline ice is typically described using only 
   the c-axis orientation, but this is insufficient for a full description of 
   grain orientations in this hexagonal material. Thus, both the a-axis and 
   c-axis are used in this data set showing pole figures for five depths of the 
   Siple Dome (SDMA) core between 640 m and 790 m and misorientation angle 
   distribution for the same grains.
