Antarctica
Antarctica () is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean, it contains the geographic South Pole. Antarctica is the fifth-largest continent, being about 40% larger than Europe, and has an area of . Most of Antarctica is covered by the Antarctic ice sheet, with an average thickness of . Antarctica is, on average, the coldest, driest, and windiest of the continents, and it has the highest average elevation. It is mainly a polar desert, with annual precipitation of over along the coast and far less inland. About 70% of the world's freshwater reserves are frozen in Antarctica, which, if melted, would raise global sea levels by almost . Antarctica holds the record for the lowest measured temperature on Earth, . The coastal regions can reach temperatures over in summer. Native species of animals include mites, nematodes, penguins, seals and tardigrades. Where vegetation o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wilhelm Archipelago
The Wilhelm Archipelago is an island archipelago off the west coast of the Antarctic Peninsula in Antarctica. Wilhelm Archipelago consists of numerous islands, the largest of which are Booth Island and Hovgaard Island. The archipelago extends from Bismarck Strait southwest to Lumus Rock, off the west coast of Graham Land. It was discovered by a German expedition under Eduard Dallmann, 1873–74. He named them for Wilhelm I, then German Emperor and King of Prussia.

Dannebrog Islands
The Dannebrog Islands are a group of islands and rocks lying between the Wauwermans Islands and the Vedel Islands in the Wilhelm Archipelago. The Wilhelm Archipelago was first sighted and named by a German expedition under Eduard Dallmann, 1873–74, and was resighted and the whole archipelago named the Flag of Denmark, Dannebrog Islands by the Belgian Antarctic Expedition, 1897–99, under Gerlache, in appreciation of support given to Gerlache by Denmark. Dallmann's original naming has been retained for the archipelago, and the name Dannebrog restricted to the smaller group here described.

Antarctic Peninsula
The Antarctic Peninsula, known as O'Higgins Land in Chile and Tierra de San Martín in Argentina, and originally as Graham Land in the United Kingdom and the Palmer Peninsula in the United States, is the northernmost part of mainland Antarctica. The Antarctic Peninsula is part of the larger peninsula of West Antarctica, protruding from a line between Cape Adams (Weddell Sea) and a point on the mainland south of the Eklund Islands. Beneath the ice sheet that covers it, the Antarctic Peninsula consists of a string of bedrock islands; these are separated by deep channels whose bottoms lie at depths considerably below current sea level. They are joined by a grounded ice sheet. Tierra del Fuego, the southernmost tip of South America, is about away across the Drake Passage. The Antarctic Peninsula is in area and 80% ice-covered. The marine ecosystem around the western continental shelf of the Antarctic Peninsula (WAP) has been subjected to rapid climate change. Over the past 50 ...

Shark
Sharks are a group of elasmobranch fish characterized by a cartilaginous skeleton, five to seven gill slits on the sides of the head, and pectoral fins that are not fused to the head. Modern sharks are classified within the clade Selachimorpha (or Selachii) and are the sister group to the rays. However, the term "shark" has also been used to refer to all extinct members of Chondrichthyes with a shark-like morphology, such as hybodonts and xenacanths. The oldest modern sharks are known from the Early Jurassic. They range in size from the small dwarf lanternshark (''Etmopterus perryi''), a deep sea species that is only in length, to the whale shark (''Rhincodon typus''), the largest fish in the world, which reaches approximately in length. Sharks are found in all seas and are common to depths up to . They generally do not live in freshwater, although there are a few known exceptions, such as the bull shark and the river shark, which can be found in both seawater and fresh ...

Booth Island
Booth Island (or Wandel Island) is a rugged, Y-shaped island, long and rising to off the northwest coast of Kyiv Peninsula in Graham Land, Antarctica in the northeastern part of the Wilhelm Archipelago. The narrow passage between the island and the mainland is the Lemaire Channel. History The island was discovered and named by a German expedition under Eduard Dallmann 1873–74, probably for Oskar Booth or Stanley Booth, or both, members of the Hamburg Geographical Society at that time. The Belgian Antarctic Expedition of 1897–1899 applied the name "Wandel Island", for Danish polar explorer and hydrographer Carl Frederick Wandel, but the United States Advisory Committee on Antarctic Names rejected the name in favor of the earlier Booth Island. The name Wandel was retained for the island's highest point. Although many of the island's features were probably first seen by Dallmann's expedition, the island was not charted in detail until the Third French Antarctic Expedition ...

Scientific Committee On Antarctic Research
The Scientific Committee on Antarctic Research (SCAR) is an interdisciplinary body of the International Science Council (ISC). SCAR coordinates international scientific research efforts in Antarctica, including the Southern Ocean. SCAR's scientific work is administered through several discipline-themed ''science groups''. The organisation has observer status at, and provides independent advice to Antarctic Treaty Consultative Meetings, and also provides information to other international bodies such as the Intergovernmental Panel on Climate Change (IPCC) and the United Nations Framework Convention on Climate Change (UNFCCC). History At the International Council of Scientific Unions (ICSU)’s Antarctic meeting held in Stockholm from 9–11 September 1957, it was agreed that a committee should be created to oversee scientific research in Antarctica. At the time there were 12 nations actively conducting Antarctic research and they were each invited to nominate one delegate to ...
