| Zusammenfassung |
| The formulation of a 3-D ice sheet-shelf model is described. The model is
designed for long-term continental-scale applications, and has been used
mostly in paleoclimatic studies. It uses a hybrid combination of the scaled
shallow ice and shallow shelf approximations for ice flow. Floating ice
shelves and grounding-line migration are included, with parameterized ice
fluxes at grounding lines that allows relatively coarse resolutions to be
used. All significant components and parameterizations of the model are
described in some detail. Basic results for modern Antarctica are compared
with observations, and simulations over the last 5 million years are
compared with previously published results. The sensitivity of ice volumes
during the last deglaciation to basal sliding coefficients is discussed. |
