A sub-forum for Elmer/ice related problems has been started within the Elmer forum (direct link). This was on request made by a few people at the Elmer/Ice splinter meeting at EGU General Assembly 2013 in Vienna to have an documented channel for problems and their solutions revolving around ice simulations.
Don't miss the first Elmer/Ice users meeting to be held during the EGU 2013, Tuesday 9th April 12:15-15:00, Room Y3. More information regarding this meeting can be found here.
Here is a list of the known Elmer/Ice talks and posters that will be presented at the forthcoming EGU in Vienna, 8-12 April 2013. Please, if your talk/poster is not listed, contact me (OG) and I will add your presentation.

In the recently published paper by Drouet et al. (2013), the first comparison of flow-line marine ice sheet models during transient is proposed. Indeed, the transient grounding line (i.e., the junction between the grounded ice sheet and the floating ice shelf) behaviour of four different flowline ice-sheet models has been compared. The models differ in the physics implemented (full Stokes and shallow shelf approximation), the numerical approach, as well as the grounding line treatment. Their overall response to the loss of buttressing is found to be broadly consistent in terms of grounding line position, rate of surface elevation change and surface velocity. However, still small differences appear for these latter variables, and they can lead to large discrepancies (> 100%) observed in terms of ice sheet contribution to sea level when cumulated over time. Despite the recent important improvements of marine ice-sheet models in their ability to compute steady state configurations, our results question the capacity of these models to compute short-term reliable sea-level rise projections.
