During the austral summer seasons 1999/2000 and 2000/2001 the summer base"Kohnen" was built as a platform for the EPICA deep ice core drilling in DronningMaud Land, Antarctica. The design is based on prefabricated container units. Thebase was erected within two summer seasons. Overland traverses with Pistenbullytractors and cargo sledges moved all needed material and base containers from theGerman base Neumayer at the Antarctic coast to the base Kohnen 750 km inland.All installations are completed at the end of the 2000/2001 season including thedrill and science trench with a cased 100-m borehole. Thus everything is preparedto start the deep drilling operation during the 2001/2002 austral summer season.
