CANBERRA, Australia — An Australian icebreaker carrying 52 passengers who were retrieved from an icebound ship in the Antarctic resumed its journey home on Saturday after it was halted for a second potential rescue operation.
The Aurora Australis had been slowly cracking through thick ice toward open water after a Chinese ship's helicopter on Thursday plucked the passengers from their stranded Russian research ship and carried them to an ice floe near the Australian ship. But on Friday afternoon, the crew of the Chinese icebreaker that had provided the helicopter said they were worried about their own ship's ability to move through the ice.
The Australian Maritime Safety Authority's Rescue Coordination Centre, which oversaw the rescue, told the Aurora on Friday afternoon to stay in the area in case help was needed.
Under international conventions observed by most countries, ships' crews are obliged to take part in such rescues and the owners carry the costs.
AMSA said the Aurora was allowed on Saturday to continue its journey despite the Chinese ship Snow Dragon, or Xue Long in Chinese, remaining stuck in ice.
"The master of Xue Long has confirmed to AMSA that the ship is safe, it is not in distress and does not require assistance at this time," AMSA said in a statement.
An attempt by the Snow Dragon to manoeuver through the pack ice during optimal tidal conditions early Saturday failed. The Chinese ship remains stuck several kilometers (miles) from the Russian icebreaker Akademik Shokalskiy, from which the passengers were rescued. The Russian ship has been immobile since Christmas Eve.
A reporter for China's official Xinhua News Agency aboard the Snow Dragon, Zhang Jiansong, reported an iceberg appeared overnight and blocked the ship's return route. He said the ship will again try to find a way out, possibly as early as Monday.
