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.
