Abstract. The full Stokes equations are solved by a finite element method for simulation of large ice sheets and glaciers. The simulation is particularly sensitive to the discretization of the grounding line which separates the ice resting on the bedrock and the ice floating on water and is moving in time. The boundary conditions at the ice base are enforced by Nitsche's method and a subgrid treatment of the elements in the discretization close to the grounding line. Simulations with the method in two dimensions for an advancing and a retreating grounding line illustrate the performance of the method. It is implemented in the two dimensional version of the open source code Elmer/ICE.

Short summary
A full Stokes subgrid model for the grounding line migration problem is presented in the open source finite element framework Elmer/ICE. This method can achieve comparable results to previous research using much larger mesh size, which can improve the efficiency in marine ice simulations.
