Left to right: Roald Amundsen, Helmer Hanssen, Sverre Hassel and Oscar Wisting after first reaching the South Pole on 16 December 1911. The Heroic Age of Antarctic Exploration was an era in the exploration of the continent of Antarctica which began at the end of the 19th century, and ended after the First World War; the Shackleton–Rowett Expedition of 1921–1922 is often cited by historians ...
A sea-level rise of 3.3 m (10 ft 10 in) would occur if the ice sheet collapses, leaving ice caps on the mountains, and 4.3 m (14 ft 1 in) if those ice caps also melt. [101] Isostatic rebound may contribute an additional 1 m (3 ft 3 in) to global sea levels over another 1,000 years. [ 100 ]
In the second half of the 19th century, one of the commanders of the research expeditions from around 1840 was considered to be the discoverer of Antarctica. In Europe, Jules Dumont d'Urville was usually considered, while in America, Charles Wilkes. Wilkes's priority was challenged due to his changing the reported date of his first sighting of ...
2019 – SD 1020, an unmanned surface vehicle (USV) designed by British engineer Richard Jenkins of Saildrone, Inc. in Alameda, CA, completed the first autonomous circumnavigation of Antarctica, sailing 22,000 km (12,000 nmi) through the Southern Ocean in 196 days, from 19 January 2019 to 3 August 2019.
The expedition ship RRS Discovery in the Antarctic alongside the Great Ice Barrier, now known as the Ross Ice Shelf. The Discovery Expedition of 1901–1904, known officially as the British National Antarctic Expedition, was the first official British exploration of the Antarctic regions since the voyage of James Clark Ross sixty years earlier (1839–1843).
From the early 15th century to the early 17th century the Age of Discovery had, through Portuguese seafarers, and later, Spanish, Dutch, French and English, opened up southern Africa, the Americas (New World), Asia and Oceania to European eyes: Bartholomew Dias had sailed around the Cape of southern Africa in search of a trade route to India; Christopher Columbus, on four journeys across the ...
The matter was unresolved when Scott returned from sea duty in May 1907. Scott pressed for a line of demarcation at 170° W—everything to the west of that line, including McMurdo Sound, Ross Island, and Victoria Land, would be Scott's preserve. Shackleton, with other concerns pressing on him, felt obliged to concede.
Colonization of Antarctica is the establishing and maintaining of control over Antarctic land for exploitation and possibly settlement. [1]Antarctica was claimed by several states since the 16th century, culminating in a territorial competition in the first half of the 20th century when its interior was explored and the first Antarctic camps and bases were set up.
