Mount Siple

	Mount Siple Mount Siple is a Potentially active volcano, potentially active Antarctica, Antarctic shield volcano, rising to and dominating the northwest part of Siple Island, which is separated from the Bakutis Coast, Marie Byrd Land, by the Getz Ice Shelf. Its youthful appearance strongly suggests that it last erupted in the Holocene. It is capped by a summit caldera, and tuff cones lie on the lower flanks. Recely Bluff is on the northeast slope of the mountain, about 7 nautical miles (13 km) from the peak. Its volume of is comparable to that of Mount Erebus. Mount Siple is named after Paul A. Siple (1908–68), a US Antarctic explorer and geographer who took part in six Antarctic expeditions, including the two Byrd expeditions of 1928-30 and 1933-35 (Siple Coast, Siple Island). He was in command of the Little America (exploration base), West Base of the US Antarctic Service (USAS), 1939–41, and was navigator on all major exploratory flights from the base, including the flight on ...

	Siple Island Siple Island is a long snow-covered island lying east of Wrigley Gulf along the Getz Ice Shelf off Bakutis Coast of Marie Byrd Land, Antarctica. Its centre is located at . Its area is and it is dominated by the dormant shield volcano Mount Siple, rising to — making this the List of islands by highest point, 15th ranking island in the world by maximum elevation. The feature was first indicated as an island on U.S. Geological Survey (USGS) maps compiled from ground surveys and U.S. Navy air photos, 1959–65. Island and mountain were named by the United States Advisory Committee on Antarctic Names (US-ACAN) in 1967 in honour of the American Antarctic explorer Paul A. Siple (1909–1968), member of Richard E. Byrd, Admiral Byrd's expeditions.

picture info	Calderas Of Antarctica A caldera ( ) is a large cauldron-like hollow that forms shortly after the emptying of a magma chamber in a volcano eruption. When large volumes of magma are erupted over a short time, structural support for the rock above the magma chamber is gone. The ground surface then collapses into the emptied or partially emptied magma chamber, leaving a large depression at the surface (from one to dozens of kilometers in diameter). Although sometimes described as a crater, the feature is actually a type of sinkhole, as it is formed through subsidence and collapse rather than an explosion or impact. Compared to the thousands of volcanic eruptions that occur each century, the formation of a caldera is a rare event, occurring only a few times per century. Only seven caldera-forming collapses are known to have occurred between 1911 and 2016. More recently, a caldera collapse occurred at Kīlauea, Hawaii in 2018. Etymology The term ''caldera'' comes from Spanish ', and Latin ', meaning "co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]

picture info	American Geophysical Union The American Geophysical Union (AGU) is a 501(c)(3) nonprofit organization of Earth, atmospheric, ocean, hydrologic, space, and planetary scientists and enthusiasts that according to their website includes 130,000 people (not members). AGU's activities are focused on the organization and dissemination of scientific information in the interdisciplinary and international fields within the Earth and space sciences. The geophysical sciences involve four fundamental areas: atmospheric and ocean sciences; solid-Earth sciences; hydrologic sciences; and space sciences. The organization's headquarters is located on Florida Avenue in Washington, D.C. History The AGU was established in December 1919 by the National Research Council (NRC) to represent the United States in the International Union of Geodesy and Geophysics (IUGG), and its first chairman was William Bowie of the United States Coast and Geodetic Survey (USCGS).

picture info	Adélie Penguin The Adélie penguin (''Pygoscelis adeliae'') is a species of penguin common along the entire coast of the Antarctic continent, which is the only place where it is found. It is the most widespread penguin species, and, along with the emperor penguin, is the most southerly distributed of all penguins. It is named after Adélie Land, in turn named for Adèle Dumont d'Urville, who was married to French explorer Jules Dumont d'Urville, who first discovered this penguin in 1840. Adélie penguins obtain their food by both predation and foraging, with a diet of mainly krill and fish. Taxonomy and systematics The first Adélie penguin specimens were collected by crew members of French explorer Jules Dumont d'Urville on his expedition to Antarctica in the late 1830s and early 1840s. Jacques Bernard Hombron and Honoré Jacquinot, two French surgeons who doubled as naturalists on the journey, described the bird for science in 1841, giving it the scientific name ''Catarrhactes adeli� ...

It is the first English-language news channel to be headquartered in the Middle East. Instead of being run centrally, news management rotates between broadcasting centres in Doha and London. History The channel was launched on 15 November 2006, at 12:00 PM GMT. It had aimed to begin broadcasting in June 2006 but had to postpone its launch because its HDTV technology was not yet ready. The channel was due to be called ''Al Jazeera International'', but the name was changed nine months before the launch because one of the channel's backers argued that the original Arabic-language channel already had an international scope. The channel was anticipated to reach around 40 million households, but it far ex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]

picture info	Penguin Move Penguins (order (biology), order List of Sphenisciformes by population, Sphenisciformes , family (biology), family Spheniscidae ) are a group of Water bird, aquatic flightless birds. They live almost exclusively in the Southern Hemisphere: only one species, the Galápagos penguin, is found north of the Equator. Highly adapted for life in the water, penguins have Countershading, countershaded dark and white plumage and flippers for swimming. Most penguins feed on krill, fish, squid and other forms of sea life which they catch with their bills and swallow it whole while swimming. A penguin has a spiny tongue and powerful jaws to grip slippery prey. They spend roughly half of their lives on land and the other half in the sea. The largest living species is the emperor penguin (''Aptenodytes forsteri''): on average, adults are about tall and weigh . The smallest penguin species is the Little penguin, little blue penguin (''Eudyptula minor''), also known as the fairy penguin, whic ...
