Antarctic Expeditions
The Antarctic ( or , American English also or ; commonly ) is a polar region around Earth's South Pole, opposite the Arctic region around the North Pole. The Antarctic comprises the continent of Antarctica, the Kerguelen Plateau and other island territories located on the Antarctic Plate or south of the Antarctic Convergence. The Antarctic region includes the ice shelves, waters, and all the island territories in the Southern Ocean situated south of the Antarctic Convergence, a zone approximately wide varying in latitude seasonally. The region covers some 20 percent of the Southern Hemisphere, of which 5.5 percent (14 million km2) is the surface area of the Antarctica continent itself. All of the land and ice shelves south of 60°S latitude are administered under the Antarctic Treaty System. Biogeographically, the Antarctic realm is one of eight biogeographic realms of Earth's land surface. Geography As defined by the Antarctic Treaty System, the Antarctic regi ...

60th Parallel South
The 60th parallel south is a circle of latitude that is 60 degrees south of Earth's equatorial plane. No land lies on the parallel—it crosses nothing but ocean. The closest land is a group of rocks north of Coronation Island (Melson Rocks or Governor Islands) of the South Orkney Islands, which are about 54 km south of the parallel, and Thule Island and Cook Island of the South Sandwich Islands, which both are about 57 km north of the parallel (Thule island slightly closer). The parallel marks the northern limit of the Southern Ocean (though some organisations and countries, notably Australia, have other definitions) and of the Antarctic Treaty System. It also marks the southern boundary of the South Pacific Nuclear-Weapon-Free Zone and the Latin American Nuclear-Weapon-Free Zone. At this latitude the sun is visible for 18 hours, 52 minutes during the December solstice and 5 hours, 52 minutes during the June solstice. On December 21, the sun is at 53.83 degrees up in the sky ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Shetland Islands
The South Shetland Islands are a group of Antarctic islands with a total area of . They lie about north of the Antarctic Peninsula, and between southwest of the nearest point of the South Orkney Islands. By the Antarctic Treaty of 1959, the islands' sovereignty is neither recognized nor disputed by the signatories and they are free for use by any signatory for non-military purposes. The islands have been claimed by the United Kingdom since 1908 and as part of the British Antarctic Territory since 1962. They are also claimed by the governments of Chile (since 1940, as part of the Antártica Chilena province) and Argentina (since 1943, as part of Argentine Antarctica, Tierra del Fuego Province). Several countries maintain research stations on the islands. Most of them are situated on King George Island, benefitting from the airfield of the Chilean base Eduardo Frei. There are sixteen research stations in different parts of the islands, with Chilean stations being ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Scott Island
Scott Island is a small uninhabited island of volcanic origin in the Ross Sea, Southern Ocean, northeast of Cape Adare, the northeastern extremity of Victoria Land, Antarctica. It is long north–south, and between and wide, reaching a height of and covering an area of . Haggits Pillar, a stack reaching in height and measuring in diameter, yielding an area of less than , is located west of the island. The island has two small coves with beaches, the rest of the island being surrounded by high cliffs. One of the coves is on the northeastern coast and the other opposite Haggitts Pillar on the western coast of the island. The island was discovered and landed upon on 25 December 1902 by captain William Colbeck, commander of the SY ''Morning'', the relief ship for Robert Scott's expedition. Colbeck originally planned to name the island Markham Island, after Sir Clements Markham, but later decided to name it after Scott. Haggits Pillar is named after Colbeck's mother's ...

Peter I Island
Peter I Island ( no, Peter I Øy) is an uninhabited volcanic island in the Bellingshausen Sea, from continental Antarctica. It is claimed as a dependency of Norway and, along with Bouvet Island and Queen Maud Land, composes one of the three Norwegian dependent territories in the Antarctic and Subantarctic. The island measures approximately , with an area of ; its highest point is the ultra-prominent, Lars Christensen Peak. Nearly all the island is covered by a glacier, and it is surrounded most of the year by pack ice, making it inaccessible during these times. There is little vertebrate animal life on the island, apart from some seabirds and seals. The island was first sighted by Fabian Gottlieb von Bellingshausen on 21 January 1821 and was named for Peter I of Russia. Not until 2 February 1929 did anyone set foot on the island, when Nils Larsen and Ola Olstad's Second ''Norvegia'' Expedition, financed by Lars Christensen, was successful. They claimed it for Norway, which an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Balleny Islands
The Balleny Islands () are a series of uninhabited islands in the Southern Ocean extending from 66°15' to 67°35'S and 162°30' to 165°00'E. The group extends for about in a northwest-southeast direction. The islands are heavily glaciated and of volcanic origin. Glaciers project from their slopes into the sea. The islands were formed by the so-called Balleny hotspot. The group includes three main islands: Young, Buckle and Sturge, which lie in a line from northwest to southeast, and several smaller islets and rocks: *northeast of Young Island: Seal Rocks, Pillar *southeast of Young Island: Row Island, Borradaile Island (with Swan Base shelter hut) *south of Buckle Island: Scott Cone, Chinstrap Islet, Sabrina Islet (with Sabrina Refuge shelter hut), and the Monolith The islands are claimed by New Zealand as part of the Ross Dependency (see Territorial claims in Antarctica). Islands and rocks from north to south The islands' area totals and the highest point has been ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
