Shackleton's ship found off the Antarctic coast

The first video footage sent up from a Sabertooth confirmed this.

"This is, by far, the finest wooden shipwreck I have ever seen," said Bound. "It is upright, well proud of the seabed, intact, and in a brilliant state of preservation."

The wreck is a protected historic monument under the Antarctic Treaty and will not be touched or disturbed in any way; only filmed and surveyed.

While he never reached the South Pole, Shackleton is regarded as one of the most iconic figures from the so-called heroic age of Antarctic exploration, a period between the late 19th and early 20th centuries when intensive efforts to explore the region captured the public imagination.

Shackleton established several new records on his various missions in the area. The ill-fated Endurance expedition was among his most ambitious, with the aim of traversing the whole Antarctic continent via the South Pole.

In 1922 he embarked on what would be his final voyage, with the objective of mapping around 3,200 kilometers of Antarctic coastline.

Shackleton died of a heart attack close to the journey's beginning, just after sailing into South Georgia, and he was buried there at his wife's request.
