The interaction of dislocations with grain boundaries in polycrystalline ice have been studied using in situ deformation sychrotron x-ray topography. Specimen preparation was performed in the Ice Research Laboratory at Dartmouth College, and x-ray topography was performed at the National Sychrotron...
