Victoria University Antarctic Research Expedition Science and Logistics Reports 1982-83: VUWAE 27

[introduction]

A new portable winch capable of depths to 1000m was built for the sediment sampling programme by the Wellington firm, Accrescent Engineering. The VUW Engineering Workshop made the winch wire laying system and a load cell for measuring the tension on the wire.

The major part of the underwater camera housing was built in stainless steel by Centralloy Industries in Christchurch. The camera system which is being developed at VUW is designed to be deployed both from sea ice and shipboard platforms.

New equipment purchased this year consisted of a dual frequency echosounder used primarily for bathymetry surveys from the sea ice and a "Halda Twinmaster odometer" which was fitted to a toboggan for distance measurement. An accuracy of 5m per kilometre is expected over most sea ice "terrains".

Four new cargo boxes for scientific equipment were built in the Geology Department and orange peel grab and tide gauge recording mechanism borrowed from other departments within the University.

Two new sets of "Polar" sleeping bags and four sets of field clothing were purchased to replace worn stock.
