5 Nov. Pyne, Woodgate to Scott Base. Varcoe, Bensemann already at Scott Base with other events.
6 Nov. Loading cargo train for Cape Roberts. Winkie drill and K193 equipment. K192 and USGS survey and field equipment K047 fuel & LPG. Woodgate on overnite survival course.
7 Nov. Completed cargo loading with 2 "seal" bladders (JP8) for helo refueling at Cape Roberts.
8 Nov. Poor weather with intermittant clear periods. Left at 1030 hrs from Willies field road transition. Travelled 6 hours until visibility deteriorated, stopped east of Butter Pt. Party personnel: G. Varcoe, A. Pyne, P. Woodgate, R. Bensemann, G. Falloon (K192), and L. Skinner (K192).
9 Nov. Continued to Cape Roberts in clearing weather, arrived approx 2200 hrs. Off loaded fuel & LPG for Vanda at Marble Pt. enroute.page break
10 Nov. Drilled ice foot (5 holes) at the previous tide gauge siet to determine best site and attitude for transducer drillhole. Ice foot was significantly thicker than 2 previous seasons with pressure ice blocks incorporated into the ice foot.
11 Nov. Set up Winkie drill and ran casing to 0.5m.
12 Nov. Drilled 6.5m. Lost circulation at times in jointed rock above ice foot (approx high tide).
13 Nov. Continued drilling and broke through into free water at 12.8m. Attemped to flush hole with sea water during the night but freezing in hole occurred about 24200 hrs.
14 Nov. Overdrilled casing to 2.6m while hole was frozen (0300-0500 hrs). 3m of ABS pipe (1" bore) from Scott Base to add to LDPE liner pipe. Redrilled ice out of hole and installed liner pipe and transducer. Disassembled drill rig and equipment, repacked cargo sledges.
15 Nov. Cargo train (Varcoe, Woodgate, Bensemann) left for New Harbour 1200 hrs. Pyne remained at Cape Roberts. Removed data logger box from Met. mast and rewired for new instruments.
16 Nov. Fitting new transducer to datalogger system. Found faulty resistor in transducer to datalogger interface (AVW1).
17 Nov. Continued testing transducer with modified constant temperature programme. Decided to recheck transducer installation - poured 5 l of isopropal alcohol in liner pipe to unfreeze transducer.
18 Nov. Removed checked and reinstalled transducer. Reprogramming datalogger and renewed wind speed and director instruments.
19 Nov. Testing datalogger programmes and instruments.
20 Nov. Checking equipment. Brent George (K191) flew to Cape Roberts for familiarisation and surveying of the installation. Pyne, George return to Scott Base 2300 hrs by helo.
21 Nov. Packing equipment in early morning. Pyne return to New Zealand.
