Ship involved in Antarctic rescue faces trouble

An Australian icebreaker carrying 52 passengers who were retrieved from an icebound ship in the Antarctic was told to halt its journey home today after concerns that a Chinese vessel involved in the dramatic rescue may also become stuck in the heavy sea ice.
The icebreaker Aurora Australis had been slowly cracking through thick ice toward open water after a Chinese helicopter yesterday plucked the passengers from their stranded Russian research ship and carried them to the Aurora.
But this afternoon, the crew of a Chinese icebreaker that had provided the helicopter said they were worried about their own ship's ability to move through the ice.

The Aurora which was carrying the passengers to the Australian island state of Tasmania was told to stay in the area in case the Chinese icebreaker Snow Dragon needs help, according to the Australian Maritime Safety Authority's Rescue Coordination Centre, which oversaw the rescue.
The Snow Dragon, which is at the edge of the ice pack surrounding the Russian vessel, will attempt to push through the ice to open water early Saturday, when tidal conditions are most favourable.
The Aurora is waiting around 11 kilometres north of the Snow Dragon, said Lisa Martin, spokeswoman for the marine authority.

Authorities have not said what the next step would be if the Snow Dragon became stuck, but it is possible that the Aurora will utilise its icebreaking capabilities to assist the Chinese vessel.

The maritime authority said the decision to place the Aurora on standby was a precaution and noted there was no danger to anyone on board the Snow Dragon.
But it was yet another wrinkle in the highly complex rescue operation of those on board the Russian ship MV Akademik Shokalskiy, which got stuck in the ice on Christmas Eve.
A spot of clear weather yesterday finally allowed the multinational rescue operation after blinding snow, strong winds and thick sea ice forced rescuers to turn back time and again.
The twin-rotor helicopter, which is based on the Snow Dragon, took seven hours to carry the scientists and tourists in groups of 12 from the Russian ship to the Aurora.

Earlier, the passengers had linked arms and stomped out a landing site in the snow next to the Russian ship for the helicopter.
