Abstract
The three-dimensional polythermal ice-sheet model SICOPOLIS is applied to the
entire Antarctic ice sheet in support of the European Project for Ice Coring in
Antartica (EPICA). in this study, we focus on the deep ice core to be drilled in
Dronning Maud Land (Atlantic sector of East Antarctica) as part of EPICA. It has
not yel been decided where the exact drill-site will be situated. Our objective is
to support EPICA during its planning phase as well as during the actual drilling
process.
We discuss a transient simulation with a climate forcing derived from the
Vostok ice core and the SPECMAP sea-level record. This simulation shows the range
of accumulation, basal temperature, age and shear deformation to be expected in
the region of Dronning Maud Land. Based on these results, a possible coring
position is proposed, and the distribution of temperature, age, horizontal
velocity and shear deformation is shown for this column.
