Cook Island, South Sandwich Islands
Cook Island is the central and largest island of the Southern Thule island group, part of the South Sandwich Islands in the far south Atlantic Ocean. Southern Thule was discovered by a British expedition under Captain James Cook in 1775. Cook Island was named for Cook by a Russian expedition under Fabian Gottlieb von Bellingshausen, which explored the South Sandwich Islands in 1819–1820. The island was surveyed in 1930 by Discovery Investigations (DI) personnel on '' Discovery II'', who charted and named many of its features. Other names were later applied by the United Kingdom Antarctic Place-Names Committee (UK-APC). Geography Cook Island measures about wide. It is heavily glaciated and uninhabited. Its highest peak, Mount Harmer, rises to . Mount Holdgate rises at the southeast end of the island. Working clockwise from the northwest, the following points are found on the island's coast. All were named by DI personnel unless otherwise specified. Resolution Point is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

60th Parallel South
The 60th parallel south is a circle of latitude that is 60 degrees south of Earth's equatorial plane. No land lies on the parallel—it crosses nothing but ocean. The closest land is a group of rocks north of Coronation Island (Melson Rocks or Governor Islands) of the South Orkney Islands, which are about 54 km south of the parallel, and Thule Island and Cook Island of the South Sandwich Islands, which both are about 57 km north of the parallel (Thule island slightly closer). The parallel marks the northern limit of the Southern Ocean (though some organisations and countries, notably Australia, have other definitions) and of the Antarctic Treaty System. It also marks the southern boundary of the South Pacific Nuclear-Weapon-Free Zone and the Latin American Nuclear-Weapon-Free Zone. At this latitude the sun is visible for 18 hours, 52 minutes during the December solstice and 5 hours, 52 minutes during the June solstice. On December 21, the sun is at 53.83 degrees up in t ...

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 ...

Islands Of The South Sandwich Islands
An island or isle is a piece of subcontinental land completely surrounded by 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 islands and oceanic islands. There are also artificial islands (man-made islands). There are about 900,000 official islands in the world. This number consists of all the officially-reported islands of each country. The total number of islands in the world is unknown. There may be hundreds of thousands of tiny islands that are unknown and uncounted. The number of sea islands in the world is estimated to be more than 200,000. The ...

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 unincorpora ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maurice Channel
Maurice Channel () is a strait wide between Bellingshausen Island and Cook Island, in the South Sandwich Islands off Antarctica. In 1820, Fabian Gottlieb von Bellingshausen indirectly indicated the existence of the strait by describing Southern Thule as consisting of one high rock and three small islands. The strait was charted in 1930 by Discovery Investigations personnel on the '' Discovery II'' and named for Henry Gascoyne Maurice, a member of the Discovery Committee The Discovery Committee was a popular name for the Interdepartmental Committee for the Dependencies of the Falkland Islands established by the British Government to carry out scientific investigations (which became known as ‘Discovery Investigati ....

Bellingshausen Island
Bellingshausen Island is one of the most southerly of the South Sandwich Islands, close to Thule Island and Cook Island, and forming part of the Southern Thule group. It is named after its discoverer, Baltic German-Russian Antarctic explorer Fabian von Bellingshausen (1778–1852). The island is a basaltic andesite stratovolcano, and the latest crater, about across and deep, formed explosively some time between 1968 and 1984. Highest point is Basilisk Peak at . Its southeast point is called Isaacson Point; first charted by Discovery Investigations personnel on the '' Discovery II'' in 1930 and named for Ms. S.M. Isaacson, an assistant to the staff of the Discovery Committee. See also * Hardy Point * List of Antarctic and sub-Antarctic islands * Salamander Point Salamander Point () is the northern point of Bellingshausen Island, South Sandwich Islands.

Douglas Strait
Douglas Strait is a strait 2 nautical miles (4 km) wide between Thule Island and Cook Island, in the South Sandwich Islands. The existence of this strait was first noted by a Russian expedition under Fabian Gottlieb von Bellingshausen in 1820. It was charted in 1930 by Discovery Investigations personnel on the '' Discovery II'' and named for Vice-Admiral Sir Percy Douglas, a member of the Discovery Committee. The north entry is between Beach Point, the northeast extremity of Morrell Island, and Tilbrook Point, the northwest extremity of Cook Island. The distance between these points is 5400 meters. The south entry is narrower, and between Hewison Point and Reef Point, which are 3000 meters apart, with navigation east of Twitcher Rock Twitcher Rock () is a rock in the southern part of Douglas Strait, 55 meters high and 140 to 150 meters in diameter, lying 0.7 nautical miles (1.3 km) east of Hewison Point, the southeast point of Thule Island in the South Sandwich Isla ...

Thule Island
Thule Island, also called Morrell Island, is one of the southernmost of the South Sandwich Islands, part of the grouping known as Southern Thule. It is named, on account of its remote location, after the mythical land of Thule, said by ancient geographers to lie at the extreme end of the Earth. The alternative name Morrell Island is after Benjamin Morrell, an American explorer and whaling captain. It was espied by James Cook and his '' Resolution'' crew on 31 January 1775 during his attempt to find Terra Australis. Geography Thule Island is approximately triangular in shape and in area with a long, panhandle-like peninsula called Hewison Point, , extending to the southeast. Steep slopes ascend to a summit caldera with the peak of Mount Larsen at above sea level. Mount Larsen is named after the Antarctic explorer and whaler Carl Anton Larsen. On the southwestern end lies Wasp Point. Off Hewison Point lies the small islet of Twitcher Rock, the southernmost land on Earth exce ...
