SYDNEY (Reuters) - Fog and heavy snow mean passengers on a Russian ship stranded in Antarctica for over a week are likely to ring in the New Year trapped in the ice, as a rescue helicopter on a nearby Chinese ship waits for the weather to clear.
The helicopter on board the Snow Dragon will be used after an Australian icebreaker on Monday failed to reach the trapped Akademik Shokalskiy, the Australian Maritime Safety Authority (AMSA) said on Tuesday.
But continuing blizzard conditions mean the rescue attempt will have wait.
"Weather conditions are unlikely to start improving until tomorrow and decisions related to carrying out the rescue may be made at short notice," it said.
The Russian ship left New Zealand on November 28 on a private expedition to commemorate the 100th anniversary of an Antarctic journey led by famed Australian explorer Douglas Mawson.
It became trapped on December 24 100 nautical miles east of French Antarctic station Dumont D'Urville and about 1,500 nautical miles south of Australia's southern island state of Tasmania.
The Akademik Shokalskiy's 74 passengers include scientists and tourists, many of them Australian, and 22 Russian crew.
Expedition leader Chris Turney said the last week had been "sobering" but morale was good.
"We are all keeping busy, with twice daily briefings outlining all the information we have to hand, alongside classes through the day (knot tying, languages, yoga, photography and many others) while the science program has continued as best we can," he said on a blog for the expedition (http://www.spiritofmawson.com/)
Rescuers plan to move all of the 52 passengers from the ship to the Snow Dragon, with most crew members expected to stay on the Russian ship, AMSA said.
The Chinese ship got within sight of the Akademik Shokalskiy on Saturday, but turned back after failing to break the ice, which was more than 3 meters (10 feet) deep in places.
