The overarching goal of the work package WP1.1 'Coupling of ice sheet models with AOGCMs' is development of coupled model systems (atmosphere-ocean-ice sheets-solid Earth) that will be used for the transient simulations. This involves the general setup, the test of various effects/parametrisations and the incorporation of important processes (e.g. interactive land sea mask, dust) into the model systems. The model systems will contain interactively coupled atmosphere-ocean-ice-sheet-solid earth models. All components will be state-of-the-art models.

The task of section 1.3 there in is to implement the solid-earth component VILMA which determines the deformation response of the solid earth to surface mass redistributions on time scales from 10 to 100,000 years and the resulting sea-level variations in a gravitationally consistent manner. In accordance, this model is aimed to represent the solid earth module in the earth-system models under investigation in PalMod.

Topics that will be discussed are:

• coupling mechanisms due to changes in the land-ocean mask
• surface-load induced topography changes of the continental areas
• influence of relative sea level at the marine-based ice margins of the continental ice sheets.
