History

In 1823, British sailor James Weddell discovered the Weddell Sea. Otto Nordenskiöld, leader of the 1901–1904 Swedish Antarctic Expedition, spent a winter at Snow Hill with a team of four men when the relief ship became beset in ice and was crushed. The crew managed to reach Paulet Island where they wintered in a primitive hut. Nordenskiöld and the others were eventually picked up by the Argentine Navy at Hope Bay. All but one survived the ordeal.

The Antarctic Sound is named after the expedition ship of Otto Nordenskiöld. The sound that separates the tip of the Antarctic Peninsula from Dundee Island is also referred to as "Iceberg Alley", because of the huge icebergs that are often seen here. Snowhill Island, located east of the Antarctic Peninsula is almost completely snow-capped, hence its name. The Swedish Antarctic Expedition under Otto Nordenskiöld built a cabin on the island in 1902, where Nordenskiöld and three members of the expedition had to spend two winters.

In 1915, Ernest Shackleton 's ship, Endurance, got trapped and was crushed by ice in this sea. After 15 months on the pack-ice Shackleton and his men managed to reach Elephant Island and safely returned home. In March 2022, it was announced that the well-preserved wreck of the Endurance had been discovered four miles (6.4 km) from its anticipated location, at a depth of 3,008 metres (9,869 ft).
