When glacial giants roll over

Title	When glacial giants roll over
Authors	Anders Leverman, Potsdam Institute for Climate Impact Research (PIK)
Venue	Nature
Location	Antarctic ice sheet

In a short News & Views article in Nature, Levermann reviews the potential for tsunami-genic iceberg calving as a phenomenon and a possible hazard. PISM-PIK Antarctic ice sheet simulations gave the frequency distribution of iceberg height and energy in discharge events per decade; see box. Iceberg discharge was computed from the vertical extent of the ice sheet and the marginal velocity distribution in a present-day equilibrium state. The results show a peak in the abundance of icebergs with a height of around 400 metres, and a distribution of energies up to several kilotonnes of TNT.

We are pleased to announce the release of PISM v2.2.1.

The Danish Meteorological Institute (DMI), a leading research institution in climate and ice sheet modelling research, is offering a 3-year, full-time position as a Scientist for Modelling Ice Sheet–Climate Interaction.

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”.
