2/ Proposed Programme

The second field season of the WAVE project aimed to visit several of the major volcanic complexes of the Kohler Range, principally Mount Murphy (Appendix 1) to undertake programmes of mapping and sample collection. Later in the season, it was proposed to move to the north end of the Executive Committee Range (ECR) to page break complete work from the foreshortened 1989/90 season. For the 1990/1991 season we aimed for a LC-130 put-in at Mount Murphy (75° 22′S, 110° 40′W) and from here to travel by sledge party to Toney Mountain (75° 48′S, 115° 50′W). In the latter part of the season the party would transfer (by LC-130) to Mount Hampton (northern ECR) and from here we planned visits to the USAS Escarpment (76°S, 124 - 129°W and Crary Mountains (76° 45′S, 117° 50′W) by a BAS supplied Twin Otter aircraft. Poor weather at Mount Murphy, which resulted in the loss of roughly 2/3 work time, necessitated a change in plans such that the proposed sledging trip to Toney Mountain was scrapped. Also, due to ski damage, the close support promised by the Twin Otter did not materialise and we were only able to transfer and return a party from Mt Waesche and to pay a brief visit to the USAS Escarpment before that aircraft returned to Rothera.
