Australia’s ice breaker Aurora Australis remains in heavy sea ice off East Antarctica delaying the ship’s return to Hobart.

The research and resupply vessel was due to arrive back in port on the 5 November, but this has been delayed by at least one day.

The Aurora Australis current position is 1600 nautical miles south-west of Hobart, 80nm from the Antarctic Coast and about 200nm from Australia’s Casey station.

It’s hoped the weather will break up some of the ice around the ship and allow it to reach open water.

The scientists on board are undertaking a major sea ice research voyage, collecting a range of data using underwater vehicles and helicopters.

The delay will mean the next voyage to Davis station will also be pushed back until 9 November at the earliest.
