Handdrawn maps plotting the ships position over time, with notes recording the sea ice and icebergs observed for each plotted point. Also includes sketches of the ice edge and some fast ice positions for the area around where the ship was travelling. The maps are archived at the Australian Antarctic Division.

Ship observations, collected over the period 1980 - 2004, will be used to determine the regional and seasonal variability of the Antarctic sea ice thickness distribution. The thickness of Antarctic sea ice is not well understood, and cannot be determined from remote sensing, yet it plays an integral role in the climate system and is climatically sensitive. This project aims to establish a baseline of sea ice thickness using data compiled from many different countries, which is required by scientists across many disciplines. This is a parent record for the project. For details on individual cruises, see the child records. This work was completed as part of ASAC project 2669 - ASAC_2699.

Observations of the sea ice cover at Wilkes base in Autumn-Winter 1963. Includes water temperature, air temperature, wind speed and direction, cloud cover, relative humidity, and general notes. These documents have been archived at the Australian Antarctic Division.
