A number of idealised simulation experiments of ice rises in Antarctica using the finite element model Elmer/Ice are performed. The model solves the Stokes equations and ice rises are formed by a protrusion of the bed into the ice shelf. The surrounding ice is floating and hydrostatic pressure is applied. There is a constant influx of ice on one side of the domain and the ice is allowed to flow out of the domain on the opposite side, subject to hydrostatic pressure. The three simulations in this data repository correspond with three varying basal friction coefficients. To understand the response of ice rises to changes in sea level, we perform transient simulations increasing and decreasing sea level at a constant rate. The data includes vtu and pvtu files, which allow for visualisation of the simulation using Paraview. Each vtu file contains the data for one partition of the domain and the pvtu file allows the entire domain to be visualised. The result files can be used to restart simulations in Elmer/Ice. The mesh generation and simulation initialisation for all experiments (LowFriction, IntermediateFriction and HighFriction) are generated using the code in the Remesh and Init directories in the the LowFriction directory. The code used to run the simulations and the post-processing code are also provided.

The documentation for Elmer/Ice can be found at https://elmerice.elmerfem.org/wiki/doku.php and the documentation for Elmer (Elmer/Ice is an add-on package to Elmer) can be found at http://www.elmerfem.org/blog/documentation/ . The resolution used in the simulations is 350 m in the area encompassing the ice rise and 2000m in the surrounding area. In the vertical, the model is prescribed to have 10 layers. In these simulations, the model solves the Stokes equations and a Weertman-type friction law is applied in areas where the ice is grounded. Accumulation and basal melt are prescribed and are described in the corresponding paper. A constant total influx of ice is prescribed on one side of the domain and the ice is allowed to float out of the domain on the opposite side. A free-slip boundary condition is prescribed on the lateral boundaries. Hydrostatic pressure is applied where the ice is floating.
