Cryogenic EBSD and X-ray Laue diffraction: Data on subgrain boundaries in Antarctic ice samples

Mechanical properties and deformation behaviour of ice in the huge polar ice masses control the internal flow of ice sheets and material supply towards the oceans. As intracrystalline dislocation glide is presumed to be the main deformation process in the creep deformation of natural ice, knowledge on dislocation activity and dislocation types is of high importance for the complete understanding of ice deformation.
