Weather summary:
Another wonderfully calm day at Cape Denison. It blew hard through the night but by 9:00 the katabatic ran out of puff and the sky peeled back its clouds for another clear sunny day of melting snow.
Today's activities:
After last nights benchmark survey, there was still one more point to reference, the height difference from Mawson's original benchmark to the new tide gauge. We now have all the data that we can gather, and Jon and I were very satisfied with boasting a 6 millimetre accuracy reading from Sorensen Hut to Boat Harbour. The levelling equipment is now wrapped and strapped with our other fly off cargo. After lunch we finished off the hut tie down, finally the Sorensen extension is ready to face it first winter!
There was plenty of action over at Mawsons Hut with Anne and Michele inspecting the fragments of the tail of the air tractor in the workshop roof. While Tony did some more comparison work to pinpoint the most likely location of the rest of its remains. All the ice and snow excavation for this year is finished. Anne also did some grid mapping of the artefact scatter north of the hut.
Steve was listing inventories today and working on his users guide to the Sorensen solar power system.
On the photography front Peter Morse spent hours in Mawson's Hut getting some final images, while Brett roamed the Cape once more looking for the white penguin, and trying to capitalise on the great photographic weather. This evening Jon and I loaded some last minute items to the cage pallets that await helicopter pick up tomorrow.
Tomorrow we expect to see a helicopter arrive fairy early, we may also have the French dive team here, to complete their part of the French / Australian tide gauge survey.
Warm wishes from the MHF team
