In Capabilities and performance of Elmer/Ice, a new-generation ice sheet model, published in Geoscience Model Development, we summarise the almost 10 yr of development performed by different groups. We only focus on the past developments that are relevant for simulations of three-dimensional ice sheets. This paper presents the governing equations implemented in Elmer/Ice, the associated boundary conditions, other useful equations (such as the equation to evaluate the age of the ice), the inverse methods implemented in Elmer/Ice, some technical aspects related to the resolution of these equations in the framework of the FE method, some standard convergence and scalability tests to verify the efficiency of Elmer/Ice and finally, we provide some insights into the future planned developments.

In the paper "Enhanced basal lubrication and the contribution of the Greenland ice sheet to future sea-level rise", by Shannon et al., recently published in the Proceedings of the National Academy of Sciences of the United States of America (PNAS), it is found that basal lubrication induced by an increase of surface melt-water is likely to have a minor role in sea-level rise compared to other effects like iceberg production and surface melt.
Elmer/Ice was one of the four ice sheet models which participated to this study in the framework of the ice2sea project.

2-day beginner Elmer/Ice course, 3-4 Oct. 2013
LGGE and CSC will organize a 2-day Elmer/Ice course the 3rd and 4th of October 2013. The course is intended for persons who want to start using Elmer/Ice in their research projects.
The course will take place at LGGE (Grenoble, France). Participants should bring their own laptop with a working (serial or parallel) version of Elmer, gmsh and paraview. More information about the organization of the course will be addressed to participants later this summer.
The course is free and will be open to approximately 12 participants, on a first come first serve basis. To register, email Olivier Gagliardini.
Elmer/Ice advanced workshop, 4-6 Nov. 2013
From Monday, Nov. 4th until Wednesday, Nov. 6th, we organize an advanced Elmer/Ice workshop in the wake of the Nordic branch IGS meeting. The workshop will take place at the premises of CSC, Espoo, Finland. The course is organized on behalf of NCoE SVALI, but (if amount of seats permits) also open to any other Elmer/Ice inclined person. Course fee (165 EUR + VAT) covers lunches, coffee and material.
