| In: | Materialy Gli︠a︡t︠s︡iologicheskikh Issledovaniĭ. (2004.), Vol. 97 (2004) |
| Abstract: | Examines changing rheological properties of ice as it deforms in polar ice sheets. Discusses deformation modes of polycrystalline ice in low stress conditions. Uses evidence from Antarctic and Greenland ice cores and observations of glacier flow, to show intracrystalline dislocation glide compatible with in situ deformation measurements and fabric development. Considers how impurities and crystal size influence strain rate. Discusses origin of strain inhomogeneities within grains, and grain boundary migration and dynamic recrystallisation as efficient recovery processes. Attributes low stress exponent to recrystallization's role in accommodating basal slip. Attributes enhancement factor in LGM ice to effects of fabric and crystal size. Solid impurities impede grain growth, but do not directly affect ice viscosity. |
