Meanwhile, videos being posted by some of those on the stranded ship indicate that while life may not be too exciting, they are safe and sound. "Everybody's fine on board," passenger John Black says in one clip. "It's a fantastic adventure we're having."
The Guardian's Laurence Topham is on the Akademic Shokalskiy. A video he's posted is less rosy than those from other passengers. He reports that while "it's fun," he's beginning to feel run down. "I miss my girlfriend, I miss my family and friends. I miss banana and peanut butter milkshakes," he says.
"When it got stuck last week, the Shokalskiy was just over two weeks into its month-long journey, from Bluff in New Zealand to Commonwealth Bay in East Antarctica, following in the footsteps of the great Antarctic explorer and scientist Douglas Mawson. He led the original AAE of 1911, and the modern incarnation intended to repeat his wildlife, ocean and weather observations to build a picture of how this part of the world had changed over the past 100 years.
"The Shokalskiy has around 50 passengers — including scientists and paying members of the public — and 20 crew on board. It became stuck in the ice near Cape de la Motte in East Antarctica, around 1,500 nautical miles from Hobart in Tasmania, after strong blizzards hit the vessel on Christmas Eve."
