In 1914 Ernest Shackleton led the Imperial Trans-Antarctic Expedition aboard Endurance, intending to cross Antarctica. Pack ice trapped the ship in the Weddell Sea in January 1915, ending the intended crossing before it could begin.
The ice eventually crushed Endurance, which sank in November 1915. The expedition became a prolonged survival effort: the men moved over and camped on ice, then escaped by small boats to Elephant Island.
Shackleton and five companions sailed the small boat James Caird across the Southern Ocean to South Georgia in 1916. Shackleton then crossed the island with two companions to reach help. All 22 men left on Elephant Island were rescued that August.
The wreck of Endurance was located in the Weddell Sea in March 2022. The story connects expedition planning, polar navigation, hull design, sea ice, lifeboats, rescue, and the technology used to survey the seafloor.
A TransitSatellite map should distinguish the ship’s journey, the drift and abandonment, the open-boat escape, the James Caird voyage, and later rescue routes. Joining those landmarks with one straight line would misrepresent the history.
