The EPICA Dronning Maud Land deep drilling operation
We report on the EPICA Dronning Maud Land (East Antarctica) deep drilling operation. Starting with the scientific questions that led to the outline of the EPICA project, we introduce the setting of sister drillings at NorthGRIP and EPICA Dome C within the European ice-coring community. The progress...

We report on the EPICA Dronning Maud Land (East Antarctica) deep drilling operation.
