Inferring forms of glacier slip laws from estimates of ice-bed separation during glacier slip

Inferring forms of glacier slip laws from estimates of ice-bed separation during glacier slip

Sea-level projections depend sensitively on the parameterization used for basal slip in glacier flow models. During slip over rock-beds, ice-bed separation increases with slip velocity and basal water pressure. We present a method for using these variables and measured bed topography to estimate the...
