1 . In 1914, Ernest Shackleton and his team left England in a wooden sailing ship called the Endurance, hoping to become the first to cross Antarctica.

But in 1915, the Endurance became trapped over the Weddell Sea. The ice destroyed the Endurance and later sank it. Shackleton and all of his men abandoned the ship and managed to stay alive. Although they failed to complete the expedition, the tale of their long and difficult return is one of the most famous survival stories of all time.

Much was known about the location of the Endurance. The ship’s captain kept accurate records of the ship’s position. The ship’s photographer even took pictures of it as it went down. But the ship, deep in the icy waters near Antarctica, had never been found.

Now, a search team called “Endurance22” located the ship, which was found 1.87 miles below the ocean’s surface, about four miles south of its last known position. The team reports that the ship is in excellent shape. Even though the ship is made of wood and is over 100 years old, it has survived with little damage. Scientists say that the small worms that normally break down wooden objects underwater don’t live in the cold waters around Antarctica.

The Endurance 22 is led by the Falklands Maritime Heritage Trust. The team ran the project from an ice­breaking ship. To locate the Endurance, the team used two underwater robots called Sabertooths which can travel by themselves deep under the sea. What makes them unique is that they can travel under the ice and go where the ship can not. Once the ship was located, the Sabertooths used high­quality cameras and scanners to record the Endurance in detail.

The Endurance 22 plans to create a digital 3D model of the wreck site, using the careful scans they made. This will allow scientists to study the ship in detail without disturbing it.
