Explorer Sir Ernest Shackleton's 1914 Antarctic expedition ended with the remarkable rescue of all 27 crew members after the ship Endurance was crushed by sea ice. In 2022, a successful search for the shipwreck was conducted. Learn about sea ice facts, average concentrations, and ongoing research on ice changes in Antarctica.

5 Then and Now Shackleton 100 Endurance 100 Geography History 1
The Story So Far In brief The story so far in brief In 1914 the explorer Sir Ernest Shackleton set out on an ambitious expedition to cross the continent of Antarctica from one side to the other. He failed. However he achieved one of the greatest feats of turn of the century polar exploration; he returned with all his 27 men alive, despite the loss of his ship. Shackleton s ship, the Endurance, was crushed and sank in ice in the Weddell Sea, before his team could even begin that ill-fated attempt to cross the hostile continent of Antarctica.

Agulhas II, as part of the Endurance22 expedition, in a successful attempt to locate the missing wreck of Shackleton s ship. Find out more here Expedition Team - Endurance22 2
Sea Ice Facts: true or false? 1. 2. The worldwide sea ice cover affects the global climate. The worldwide sea ice cover acts as a large mirror for the sun, reflecting some energy back and preventing additional heating of the ocean. Much sea ice is made up of ice piled up in ridges that can be 3 metres high. Shackleton s Endurance was crushed by sea ice. Multi-year sea ice means that ice survives from one year to the next rather than melting each year. The Weddell Sea ice is the only region where you have a large area of multi-year ice in Antarctica. 3. 4. 5. 6. All statements are true and informed by the Endurance 22 website.
