Individual ice crystals possess a strong plastic anisotropy. In ice sheets and shelves this results in the development of flow-induced patterns of preferred crystallographic c-axis orientations and polycrystalline anisotropy. The deformation rates of anisotropic polycrystalline ice can be enhanced b...
