This paper presents a dynamic equilibrium simulation of the ice sheet-shelf system on Antarctica with the Potsdam Parallel Ice Sheet Model (PISM-PIK) with a focus on the Ronne-Filchner and Ross ice shelf areas as well as on the whole ice-sheet system. PISM-PIK (and now PISM) allows free movement of grounding lines and calving fronts thanks to a physically-motivated calving law based on horizontal spreading rates and an implementation of a calving-front stress boundary condition. The results support the approach of superposition of SIA and SSA for the representation of fast motion of grounded ice.

In the department of Integrative Earth system science at the newly founded Max Planck Institute of Geoanthropology (MPI-GEA) in Jena, Germany, we are providing a three-year PhD position as part of the DFG priority program “Antarctic Research with Comparative Investigations in Arctic Ice Areas”.

A two-year PostDoc positions in ice sheet and Earth system modelling is available in the Ice Dynamics group, as part of the new Earth Resilience Science Unit (ERSU), at the Potsdam Institute for Climate Impact Research (PIK).

Two PhD fellowship positions in ice sheet modelling are advertised at the Niels Bohr Institute, University of Copenhagen.
