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 ...
John Biscoe (28 April 1794 – 1843) was an English mariner and explorer who commanded the first expedition known to have sighted the areas named Enderby Land and Graham Land along the coast of Antarctica. The expedition also found a number of islands in the vicinity of Graham Land, including the Biscoe Islands that were named after him.
The history of Antarctica emerges from early Western theories of a vast continent, known as Terra Australis, believed to exist in the far south of the globe. The term Antarctic , referring to the opposite of the Arctic Circle , was coined by Marinus of Tyre in the 2nd century AD.
The colder, stabler East Antarctica had been experiencing cooling until the 2000s. [22] [23] Around Antarctica, the Southern Ocean has absorbed more oceanic heat than any other ocean, [24] and has seen strong warming at depths below 2,000 m (6,600 ft). [25]: 1230 Around the West Antarctic, the ocean has warmed by 1 °C (1.8 °F) since 1955. [21]
[3] [1] Smith interpreted this as referring to the ice floes and icebergs in the Southern Ocean, due to the ice floes being similar to arrowroot powder (referring to Tacca leontopetaloides, Polynesian arrowroot). [1] This has led others to conclude that Ui-te-Rangiora was the first person to discover Antarctica. [1] [4]
Scientists from the British Antarctic Survey found that warm ocean water is seeping beneath the ice sheet at its “grounding line” — the point at which the ice rises from the seabed and ...
The Antarctic plate is a tectonic plate containing the continent of Antarctica, the Kerguelen Plateau, and some remote islands in the Southern Ocean and other surrounding oceans. After breakup from Gondwana (the southern part of the supercontinent Pangea ), the Antarctic plate began moving the continent of Antarctica south to its present ...
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).
