A team, including members from New Zealand universities, have begun searching for Sir Ernest Shackleton’s lost ship in the Weddell Sea.
Scientists have reached the last known place of Shackleton’s ship Endurance, which was abandoned in 1915 when it became stuck in thick ice and crushed.
Endurance then sunk to the bottom of the Weddell Sea, in the Southern Ocean.
The team said the timbers of Endurance are likely to be well preserved due to the lack of organisms which rot wood in the cold sea, and the researchers are the first people to be there since Shackleton and his men.
Who is Ernest Shackleton?
Shackleton was born in Ireland and became a polar explorer at the age of 25. He wanted to become the first man to reach the South Pole, but was beaten by a Norwegian explorer called Roald Amundsen in 1911.
Shackleton became a hero after leading his 27 men to safety after the Endurance shipwreck, escaping over the frozen sea to Elephant Island.
Shackleton and his men were on the ice for almost two years, but no one died.
