Anglo-Irish explorer Ernest Shackleton set out on an epic journey in 1914 to attempt the first land crossing of Antarctica. But his ship Endurance got stuck in the ice and sank in the Weddell sea, forcing the crew to abandon the mission. An expedition this week found the wreck and has released remarkable footage of it 3000m below the surface of the Weddell Sea.
"We are overwhelmed by our good fortune in having located and captured images of Endurance," said Mensun Bound, the expedition's director of exploration, on Wednesday.
