Mount William (Antarctica)
Mount William is a prominent snowy mountain in Antarctica, standing tall, and located north-northeast of Cape Lancaster which is the south extremity of Anvers Island, in the Palmer Archipelago. This is the tallest mountain visible from Biscoe Bay, near the south end of the island's Osterrieth Range which also includes Mount Français (the tallest mountain on the island). This mountain was discovered on February 21, 1832, by John Biscoe who incorrectly believed it to be part of the mainland of Antarctic Peninsula, instead of on an island. He named it for William IV, then King of the United Kingdom.

RV Belgica (1884)
''Belgica'' was a barque-rigged steamship that was built in 1884 by Christian Brinch Jørgensen at Svelvik, Norway as the whaler ''Patria''. In 1896, she was purchased by Adrien de Gerlache for conversion to a research ship, taking part in the Belgian Antarctic Expedition of 1897–1901, becoming the first ship to overwinter in the Antarctic. In 1902, she was sold to Philippe, Duke of Orléans and used on expeditions to the Arctic in 1905 and from 1907 to 1909. In 1916, she was sold and converted to a passenger and cargo ship, serving Spitsbergen from the Norwegian mainland under the name ''Isfjord''. In 1918, she was sold and renamed ''Belgica'', being converted to a factory ship. Requisitioned by the British in April 1940, she was used as a depôt ship, being scuttled when the Franco-British Expeditionary Force evacuated Harstad in northern Norway. In 2007, plans to build a modern replica of ''Belgica'' were announced. Description The ship was long, with a beam of and a d ...

Anvers Island
Anvers Island or Antwerp Island or Antwerpen Island or Isla Amberes is a high, mountainous island long, the largest in the Palmer Archipelago of Antarctica. It was discovered by John Biscoe in 1832 and named in 1898 by the Belgian Antarctic Expedition under Adrien de Gerlache after the province of Antwerp in Belgium. It lies south-west of Brabant Island at the south-western end of the group. The south-western coastline of the island forms part of the Southwest Anvers Island and Palmer Basin Antarctic Specially Managed Area (ASMA 7). Cormorant Island, an Important Bird Area, lies 1 km off the south coast. Palmer Station The Palmer Station on Anvers Island is located at () and is Antarctica's only U.S. station north of the Antarctic Circle. Construction finished in 1968. Around 50 people can inhabit Palmer Station at one time. The station is named for Nathaniel B. Palmer, likely to have been one of the first three persons to see Antarctica.

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, 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.

Snow
Snow comprises individual ice crystals that grow while suspended in the atmosphere—usually within clouds—and then fall, accumulating on the ground where they undergo further changes. It consists of frozen crystalline water throughout its life cycle, starting when, under suitable conditions, the ice crystals form in the atmosphere, increase to millimeter size, precipitate and accumulate on surfaces, then metamorphose in place, and ultimately melt, slide or sublimate away. Snowstorms organize and develop by feeding on sources of atmospheric moisture and cold air. Snowflakes nucleate around particles in the atmosphere by attracting supercooled water droplets, which freeze in hexagonal-shaped crystals. Snowflakes take on a variety of shapes, basic among these are platelets, needles, columns and rime. As snow accumulates into a snowpack, it may blow into drifts. Over time, accumulated snow metamorphoses, by sintering, sublimation and freeze-thaw. Where the climate is co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountain
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited Summit (topography), summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are Monadnock, isolated summits, but most occur in mountain ranges. Mountain formation, Mountains are formed through Tectonic plate, tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through Slump (geology), slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce Alpine climate, colder climates than at sea level at similar latitude. These colder climates strongly affect the Montane ecosystems, ecosys ...

Cape Lancaster
Cape Lancaster () is a cape forming the southern extremity of Anvers Island, in the Palmer Archipelago, Antarctica. It was discovered by a German expedition under Eduard Dallmann, 1873–74. The cape was later sighted by the Belgian Antarctic Expedition, 1897–99, under Gerlache, who named it for Albert Lancaster, Scientific Director of the Meteorological Service of the Royal Observatory of Belgium and a supporter of the expedition.

It extends from Tower Island in the north to Anvers Island in the south. It is separated by the Gerlache and Bismarck straits from the Antarctic Peninsula and Wilhelm Archipelago, respectively. Palmer Archipelago is located at . History Adrien de Gerlache, leader of the Belgian Antarctic Expedition (1897–1899), discovered the archipelago in 1898.

Mount Français
Mount Français is a mountain which forms the summit of Anvers Island, Antarctica, in the Antarctic claims of the United Kingdom, Argentina and Chile. It stands southeast of the center of the island and 6 miles north of Borgen Bay. Mount Français has an elevation of and is part of the Trojan mountain range. History Mount Français was first seen by the members of the Belgian Antarctic Expedition, who explored the southeast coast of the island in 1898. It was later sighted by the French Antarctic Expedition team members, 1903–05, under Charcot, who named it for the expedition ship Français. Mount Français was first summited on 7 December 1955 by Jim Rennie, Arthur Shewry, and Bill Hindson, members of the Falkland Islands Dependencies Survey who had spent the 1955 winter at Base E, newly constructed north of Arthur Harbor on Anvers Island.

John Biscoe
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. Early life Biscoe was born in Enfield, Middlesex, England. In March 1812, aged seventeen, he joined the Royal Navy and served during the 1812–1815 war against the United States. By the time of his discharge in 1815, he had become a justice Master. Thereafter he sailed on board merchant shipping as a mate or master, mostly to the East or West Indies. Southern Ocean expedition, 1830–1833 In 1830, the whaling company Samuel Enderby & Sons appointed Biscoe master of the brig ''Tula'' and leader of an expedition to find new sealing grounds in the Southern Ocean.

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 ...
