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.

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 ...

Crab
Crabs are decapod crustaceans of the infraorder Brachyura, which typically have a very short projecting "tail" (abdomen) ( el, βραχύς , translit=brachys = short, / = tail), usually hidden entirely under the thorax. They live in all the world's oceans, in freshwater, and on land, are generally covered with a thick exoskeleton, and have a single pair of pincers. They first appeared during the Jurassic Period. Description Crabs are generally covered with a thick exoskeleton, composed primarily of highly mineralized chitin, and armed with a pair of chelae (claws). Crabs vary in size from the pea crab, a few millimeters wide, to the Japanese spider crab, with a leg span up to . Several other groups of crustaceans with similar appearances – such as king crabs and porcelain crabs – are not true crabs, but have evolved features similar to true crabs through a process known as carcinisation. Environment Crabs are found in all of the world's oceans, as well as in fresh w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hovgaard Island
Hovgaard Island is an island long, lying off the northwest coast of Kyiv Peninsula, southwest of Booth Island in the Wilhelm Archipelago, Antarctica. It was discovered and named "Krogmann-Insel" (Krogmann Island) by the German 1873–74 expedition under Eduard Dallmann, but the name Hovgaard, after Polar explorer and officer of the Danish Navy Andreas Hovgaard,Hovgaard Ø. In: Anthony K. Higgins: ''Exploration history and place names of northern East Greenland.'' Geological Survey of Denmark and Greenland Bulletin Bd. 21, 2010. Copenhagen 2010, applied by the Belgian Antarctic Expedition, 1897–99, under Gerlache, has overtaken the original name in usage. The name Krogmann Point has been given to the western extremity of Hovgaard Island. Hovgaard Island is a popular location for camping in Antarctica among expedition groups due to the presence of a relatively flat campsite along Penola Strait. Campers dig "snow graves" to sleep in. The holes offer protection from the wind. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...
