Montagu Island
Montagu Island ( es, Isla Jorge) is the largest of the South Sandwich Islands, located in the Scotia Sea off the coast of Antarctica. It is a part of the British Overseas Territory, South Georgia and the South Sandwich Islands. It is located northeast from Bristol Island and south from Saunders Island. The island was first sighted by James Cook in 1775, and named after John Montagu, 4th Earl of Sandwich and the First Lord of the British Admiralty at the time of its discovery. The first recorded landing was made by the Norwegian whaler and explorer Carl Anton Larsen in 1908. Geography The desolate, uninhabited island measures approximately , with over 90% of its surface permanently covered in ice. The volcano Mount Belinda is its most notable geographic feature, rising to above sea level. It was believed to be inactive prior to the sighting of low-level ash emission and suspected lava effusion in 2002 by the British Antarctic Survey. Mount Belinda In November 2005, satellit ...

Mount Belinda
Mount Belinda is a stratovolcano on Montagu Island, in the South Sandwich Islands of the Scotia Sea. A part of the British Overseas Territory, South Georgia and the South Sandwich Islands, Mount Belinda is also the highest peak in the South Sandwich Islands, at 1,370 m (4,490 ft). Belinda was inactive until late 2001, when it volcanic eruption, erupted. The eruption produced large quantities of basaltic lava, melting the thick cover of ice that had accumulated while the volcano lay dormant, and "producing a marvelous 'natural laboratory'; for studying lava-ice interactions relevant to the biology of extreme environments as well as to processes believed to be important on Mars." The activity throughout 2005 marked the highest levels yet. The increase in activity in the fall of 2005 produced an active -long lava flow, extending from the summit cone of Mount Belinda to the sea. The flow spread northeast from the volcanic vent, and then became diverted due north by an arêt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Horsburgh Point
Horsburgh Point () is a point, northwest of Scarlett Point, on the southwest side of Montagu Island in the South Sandwich Islands.

Volcanoes Of The Atlantic Ocean
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and most are found underwater. For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes can also form where there is stretching and thinning of the crust's plates, such as in the East African Rift and the Wells Gray-Clearwater volcanic field and Rio Grande rift in North America. Volcanism away from plate boundaries has been postulated to arise from upwelling diapirs from the core–mantle boundary, deep in the Earth. This results in hotspot volcanism, of which the Hawaiian hotspot is an example. Volcanoes are usually not created where two tectonic plates slide pa ...

Islands Of The South Sandwich Islands
An island (or isle) is an isolated piece of habitat that is surrounded by a dramatically different habitat, such as water. Very small islands such as emergent land features on atolls can be called islets, skerries, cays or keys. An island in a river or a lake island may be called an eyot or ait, and a small island off the coast may be called a holm. Sedimentary islands in the Ganges delta are called chars. A grouping of geographically or geologically related islands, such as the Philippines, is referred to as an archipelago. There are two main types of islands in the sea: continental and oceanic. There are also artificial islands, which are man-made. Etymology The word ''island'' derives from Middle English ''iland'', from Old English ''igland'' (from ''ig'' or ''ieg'', similarly meaning 'island' when used independently, and -land carrying its contemporary meaning; cf. Dutch ''eiland'' ("island"), German ''Eiland'' ("small island")). However, the spelling of the word ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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). For more than 50 years, it operated as an unincorporated affili ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

British Antarctic Survey
The British Antarctic Survey (BAS) is the United Kingdom's national polar research institute. It has a dual purpose, to conduct polar science, enabling better understanding of global issues, and to provide an active presence in the Antarctic on behalf of the UK. It is part of the Natural Environment Research Council (NERC). With over 400 staff, BAS takes an active role in Antarctic affairs, operating five research stations, one ship and five aircraft in both polar regions, as well as addressing key global and regional issues. This involves joint research projects with over 40 UK universities and more than 120 national and international collaborations. Having taken shape from activities during World War II, it was known as the Falkland Islands Dependencies Survey until 1962. History Operation Tabarin was a small British expedition in 1943 to establish permanently occupied bases in the Antarctic. It was a joint undertaking by the Admiralty and the Colonial Office.
