Antarctic Convergence
The Antarctic Convergence or Antarctic Polar Front is a marine belt encircling Antarctica, varying in latitude seasonally, where cold, northward-flowing Antarctic waters meet the relatively warmer waters of the sub-Antarctic. Antarctic waters predominantly sink beneath the warmer subantarctic waters, while associated zones of mixing and upwelling create a zone very high in marine productivity, especially for Antarctic krill. This line, like the arctic tree line, is a natural boundary rather than an artificial one, such as the borders of nations and time zones. It not only separates two hydrological regions, but also separates areas of distinctive marine life and climates. The Arctic has no similar boundary because of the large bodies of land contiguous with the northern polar region. History The Antarctic Convergence was first crossed by Anthony de la Roché in 1675, and described by Edmond Halley in 1700. Location The Antarctic Convergence is a zone approximately wide, ...

Isla De Los Estados
Isla de los Estados (English: Staten Island, from the Dutch ''Stateneiland'') is an Argentine island that lies off the eastern extremity of Tierra del Fuego, from which it is separated by the Le Maire Strait. It was named after the Netherlands States-General, the Dutch parliament. The island is part of the Argentinian province of Tierra del Fuego, and of the department and city of Ushuaia. It has been declared an "Ecological, Historic, and Tourist Provincial Reserve" ("''Reserva provincial ecológica, histórica y turística''"), with access limited to tours from Ushuaia. The only settlement is the Puerto Parry Naval Station, located in a deep and narrow fjord on the northern coast of the island. The naval station, established in 1978, is manned by a team of four marines on a 45-day rotation. They monitor environmental conservation and ship movements, and provide emergency assistance. History Prior to European arrival, the island was visited by the Yamana people, who inhabite ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Crown
The Crown is the state in all its aspects within the jurisprudence of the Commonwealth realms and their subdivisions (such as the Crown Dependencies, overseas territories, provinces, or states). Legally ill-defined, the term has different meanings depending on context. It is used to designate the monarch in either a personal capacity, as Head of the Commonwealth, or as the king or queen of their realms (whereas the monarchy of the United Kingdom and the monarchy of Canada, for example, are distinct although they are in personal union). It can also refer to the rule of law; however, in common parlance 'The Crown' refers to the functions of government and the civil service. Thus, in the United Kingdom (one of the Commonwealth realms), the government of the United Kingdom can be distinguished from the Crown and the state, in precise usage, although the distinction is not always relevant in broad or casual usage. A corporation sole, the Crown is the legal embodiment of ex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chile
Chile, officially the Republic of Chile, is a country in the western part of South America.

Chile covers an area of , with a population of 17.5 million as of 2017. It shares land borders with Peru to the north, Bolivia to the north-east, Argentina to the east, and the Drake Passage in the far south.

Diego Ramírez Islands
The Diego Ramírez Islands ( es, Islas Diego Ramírez) are a small group of subantarctic islands located in the southernmost extreme of Chile. History The islands were first sighted on 12 February 1619 by the Spanish Garcia de Nodal expedition, and named after the cosmographer of the expedition, Diego Ramírez de Arellano. They were cited as the southernmost land mass plotted as of that time, and retained the distinction for 156 years, until the discovery of the South Sandwich Islands in 1775. In 1892, the Chilean government rented the islands to Pedro Pablo Benavides for fishing and on condition that a lighthouse, a port, and a school would be built. Later the rent was transferred to Koenigswerther and Pasinowich. The Chilean Navy established a meteorological station above Caleta Condell, a small cove on the northeastern side of Isla Gonzalo (Gonzalo Island), in 1957, and resupplies it several times each year.Dingwall (1995), p. 109. This is the southernmost inhabited outpos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crozet Islands
The Crozet Islands (french: Îles Crozet; or, officially, ''Archipel Crozet'') are a sub-Antarctic archipelago of small islands in the southern Indian Ocean. They form one of the five administrative districts of the French Southern and Antarctic Lands. History Discovery and early history The Crozet Islands were discovered on 24 January 1772, by the expedition of French explorer Marc-Joseph Marion du Fresne, aboard ''Le Mascarin''. His second-in-command Jules (Julien-Marie) Crozet landed on Île de la Possession, claiming the archipelago for France. The expedition continued east and landed in New Zealand, where Captain Marion and much of his crew were killed and cannibalized by Maori. Crozet survived the disaster, and successfully led the survivors back to their base in Mauritius. In 1776, Crozet met James Cook at Cape Town, at the start of Cook's third voyage. Crozet shared the charts of his ill-fated expedition, and as Cook sailed eastward, he stopped at the islands, namin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Île Amsterdam
Île Amsterdam (), also known as Amsterdam Island and New Amsterdam (''Nouvelle-Amsterdam''), is an island of the French Southern and Antarctic Lands in the southern Indian Ocean that together with neighbouring Île Saint-Paul to the south forms one of the five districts of the territory. The island is roughly equidistant to the land masses of Madagascar, Australia, and Antarctica – as well as the British Indian Ocean Territory and the Cocos (Keeling) Islands (about from each). The research station at Martin-de-Viviès, first called ''Camp Heurtin'' and then ''La Roche Godon'', is the only settlement on the island and is the seasonal home to about thirty researchers and staff studying biology, meteorology, and geomagnetics. History The first person known to have sighted the island was the Spanish explorer Juan Sebastián de Elcano, on 18 March 1522, during his circumnavigation of the world. Elcano did not give the island a name. On 17 June 1633, Dutch mariner Anthon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
