Marine Ice Sheet Model Intercomparison Project
The last few years have seen a great deal of effort invested by various research groups in developing numerical marine ice sheet models that are intended to represent accurately the motion of an ice sheet grounding line, and this effort has seen a variety of models emerge. It is at present unclear to what extent these models agree with one another, or indeed, how well they are able to model real marine ice sheets.
The purpose of the proposed experiments is to address the former question: how well do our models agree with one another? In addition, the purpose of the experiments is also to assess how well the numerical schemes used solve the partial differential equations on which they are based. Not all the models used in marine ice sheet simulations deal with the same equations, but many of them share basic characteristics. For instance, most include a representation of the longitudinal stresses required to couple ice shelves to the ice sheet. We therefore do not restrict this intercomparison to a single type of model, but invite a variety of models described below to participate.
