Equation () is valid for b-z sl < 0; otherwise p w =0.By definition, p w =ρ i gh at the grounding line and underneath floating ice shelves, so the effective pressure becomes zero (or close to zero … 웹2024년 5월 10일 · We develop Bayesian statistical models that are designed for the inference of ice softness and basal sliding parameters, important glaciological quantities. These models are applied to Langjökull, the second largest temperate ice cap in Iceland at about 900 squared kilometers in area. The models make use of a relationship between physical …
웹2024년 1월 16일 · 67.4.1.1.4 Role of basal meltwater. The presence of water-filled cavities at the ice-bedr ock interface enhances sliding speed through separating ice from its bed, increasing the shear stress on the locations remaining in contact, and exerting a net down-glacier force on the overlying ice. Although these processes have not been incorporated ...
