ICE RISE Antarctic Ice Rise Response to Sea Level Hysteresis Experiment

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.
