NZARP REPORT No 2 LOGISTIC REPORT TO DSIR ANTARCTIC
K-048 WEST ANTRACTIC VOLCANO EXPLORATION (WAVE)
Antarctica New Zealand October 1990 - January 1991
The aim and objectives of the WAVE programme are to understand better the volcanology of the late Cenozoic Volcanic Province of West Antarctica, to document in detail the chronology of individual volcanoes and to elucidate the petrogenesis of the magmas and their sources. In addition, xenoliths carried to the surface by volcanic processes would be used to reconstruct sections through the lithosphere.
Logistic planning for phase two of the WAVE programme had been established in June 1989. Further planning was undertaken at the Tekapo orientation meeting and final details decided at a briefing with VXE-6 in Mc Murdo.
Some equipment was transported to Scott Base as a part of the VUWAE shipment. Some equipment from the 1989/90 season had been stored over at Scott Base and in a sealed cage at Mc Murdo (BFC). No excess baggage was carried to or from Scott Base. Some 8001bs of rock samples were returned to New Zealand by Gamble for study at Victoria University.

This party was augmented by personnel from USAP S-081: W.C. McIntosh and K.T.
Panter and P.R. Kyle and N.W. Dunbar (the latter 2 from 2nd January 1991).
PREPARATIONS FOR THE FIELD
The party (including S-081) assembled in Christchurch on 30th October 1990 and after a 24 hour cancellation due to bad weather at McMurdo, departed on 1st November 1990 for the ice. The flight was event free. Field equipment, tents, cooking equipment and provisions were assembled at Scott Base and McMurdo in the period 2nd to 8th November 1990. Recce flights planned on the 4th and 5th November were both cancelled due to poor weather in Marie Byrd Land. Skidoos page break and several of the sledges were tested during a number of short shake down trips along and over Hut Point Peninsula. Put-in to Mount Murphy was on 10th November 1990.
A detailed report on the effectiveness of the Bombadier Alpine 503 skidoos and sledges for transportation was presented in the 1989/90 WAVE report. Similar transport was used this season but fuel was air-dropped during the recce flight We can report that our mechanical equipment again performed well and few running repairs were necessary. Further details are included in the Field Leaders report (Appended as Appendix 2).

A map is enclosed a Appendix 1 to this report. The map includes details of camp sites in the vicinity of Mount Murphy.
Full details of the weather are contained in the Appendix 3. Weather was again rather fickle and we were only able to work on 35% of the time spent at Mount Murphy. During this time we were blessed with a period of continuous fine weather which lasted 13 days but this intervened storms which lasted 8 days and then 13 days.
No serious accidents occurred during the field season although JAG sustained a bump on the head as a result of some inattentive skidoo driving by an unnamed individual.
Comments regarding the performance of the field equipment are contained in the report by the NZARP field leader. (Appendix 2).
Radio communicantions used USAP supplied Southcom transmitter-receivers and good communications were enjoyed with S. Pole, Mac Centre and CAZERTZ. Communications with Scott Base were non existent and we used K-051 to relay messages.
The Tait hand held radios performed perfectly as did the solar charging units. The USAP personnel brought Motorola hand helds and we were able to use the same frequency. Hand helds proved much more successful this season than the previous season.
This season all waste apart from human wastes (which was buried) was returned to McMurdo for disposal. Plastics, paper and metallic wastes were sorted at the putin site and packed in cardboard containers.
