  abstract =     {The principal aim of the Expedition was to continue
                  and complete certain aspects of the detailed
                  glaciological survey of the Roslin glacier carried out
                  by the Cambridge Staunings Expedition of 1970, namely:
                  1. To locate and re-establish the August 1970 stake
                  patterns on the upper Roslin glacier, and to fix their
                  new positions by theodolite triangulation.  2. To map
                  by plane table the lower 2 kilometres of the Roslin
                  glacier.  3. To measure the conductivity of the ice
                  melt water at various points on the Roslin glacier.}
