Logistics of the GEISHA Expedition

Summary: The geological expedition to the Shackleton Range (GEISHA 1987/ 88) was not only rhe southernmost German Antarctic cxpedition, but also a logistically cornplex operation. Addilionally, thc initiallogistic concept had to he modified during the planning and preparation phases. Instead of transport to the Shackleton Range hy land two ski-equipped aircraft werc necessary. Additionally, the RV Polarstern had to be used to rcach the Brunt Ice Shelf near the British Halley Station, from whcre the geological expedition to the Shackleton Range was to start. To make optimum use of the short time availablc, the field work was supported by two helicopters in addition to motor toboggans (skidoos) and sledges. which were available at each camp, making it possible to continue the scientific programs even on white-out days. This worked out very weil and more field work could be done than originally planned.
