Abstract

This document is a compilation of weekly sea ice reports for the East Antarctic. The reports were prepared to support ship operations in the region during the shipping season in 2011/2012. They were primarily used as a guidance for the Australian Antarctic program, but were partly provided to other Antarctic operators as well. The focus of individual reports shifts with the main purpose of specific voyages of the Australian Antarctic research and supply vessel Aurora Australis throughout the season. The Antarctic voyages of the 2011/2012 season were: No. Leave port Main Purpose Return V1 23/10/2011 Davis resupply 26/11/2011 V2 02/12/2011 Casey resupply 03/01/2012 V3 05/01/2012 Commonwealth Bay visit and Marine Science 12/02/2012 V4 15/02/2012 Mawson resupply 15/03/2012 V5 17/03/2012 Recover Davis and Casey summer personnel 14/04/2012 V6 16/04/2012 Macquarie Island resupply 01/05/2012 Whenever required, the Sea Ice Group prepared sub-weekly updates for specific regions. In general, the sea ice conditions for the 2011/2012 season can be regarded as close to average. However, two regions of particular concern were; the Commonwealth Bay region, where a grounded iceberg had a profound influence on the local sea ice conditions and prevented ship access into the bay and to Mawson's Hut, and the second, an unusually persistent land-fast sea ice off Mawson Station that threatened to prevent full resupply of the station.
