Antarctic passengers on dry land

An expedition of 52 scientists and tourists arrived in Australia today, setting foot on dry land for the first time since they were rescued from a ship trapped in Antarctic sea ice three weeks ago.
Expedition leader Chris Turney told reporters who greeted them in the port city of Hobart where they ended the final leg of their rescue journey aboard an Australian icebreaker that it was still not clear who would pay for their rescue.
"I understand four nations helping is quite unusual. That's not our call .... that's beyond our control," he said.
Prof T urney's expedition began on November 28. They had been retracing an expedition a century ago by Australian explorer Douglas Mawson and comparing scientific measurement made then and now when their Russian icebreaker Akademik Shokalskiy became trapped in ice-clogged Commonwealth Bay on Christmas Eve.
Australian, French and Chinese icebreakers were directed by Australia's rescue co-ordination centre to come to their rescue.
Under international conventions observed by most countries, ships' crews are obliged to take part in such rescues and the owners carry the costs.
A helicopter from the Chinese icebreaker was able to ferry the passengers from the Russian ship to the Australian icebreaker Aurora Australis on January 2. The following day, the Chinese ship reported it too was stuck in ice.
US Coast Guard heavy icebreaker, Polar Star, was sent from Sydney to rescue the Russian and Chinese ships, but both icebreakers were able to free themselves before the American cutter arrived.
The Australian ship continued its resupplying mission to Australia's Antarctic base, Casey Station, before returning to its home port, Hobart.
Australian Antarctic Division director Tony Fleming estimated the cost of the rescue to the Australian government was between 1.8 million Australian dollars (£1 million) and 2.4 million Australian dollars (£1.3 million).
This did not include the costs to research projects scheduled to be conducted during the narrow window of the Antarctic summer.
Some would have to be postponed because of the delay in scientific equipment and supplies arriving at Casey aboard the Australian ship.
Australia was discussing costs with both the insurers of the Russian ship and of the University of New South Wales which chartered it, Mr Fleming said.
