Abstract
A simplified model of plane isothermal steady ice flow in the land-based part, the shelf and the ice-sheet-ice-shelf transition zone of a glacier which interacts with the sea is constructed using Glen's flow law and perturbation methods. Boundary conditions on the joining line are obtained for the land-based part of the glacier. The dynamics of the ice-divide domain of the glacier is analysed for the case of axially symmetric, steady, isothermal ice flow.
