PORT STANLEY, the Falkland Islands – Researchers have discovered the remarkably well-preserved wreck of polar explorer Ernest Shackleton’s ship, Endurance, in 10,000 feet of icy water, a century after it was swallowed up by Antarctic ice during what proved to be one of the most heroic expeditions in history. A team of marine archaeologists, engineers and other scientists used an icebreaker ship and underwater drones to locate the wreck at the bottom of the Weddell Sea, near the Antarctica Peninsula. The Falklands Maritime Heritage Trust’s search expedition Endurance22 announced the discovery on March 9.
