Abstract

A series of benchmark experiments are presented designed for testing and comparing numerical ice sheet models. Following the outcome of two EISMINT workshops organized for this purpose, model experiments are described for ice sheets under fixed margin as well as under moving margin conditions. These address both steady-state and time-dependent behaviour under schematic boundary conditions and with prescribed physics. The emphasis is on numerical aspects and on comparing results in situations where analytical solutions do not exist. Most of the large-scale ice-sheet models currently in operation were subjected to these tests, and a comparison was made of basic geophysical variables such as ice thickness, velocity and temperature. Here we present the consensus results which emerged, thereby providing reference solutions against which the accuracy and consistency of ice-sheet modeling codes can be assessed.
