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 the fifth-largest continent, being about 40% larger than Europe, and has an area of . Most of Antarctica is covered by the Antarctic ice sheet, with an average thickness of . 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. Native species of animals include mites, nematodes, penguins, seals and tardigrades. Where vegetation o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biscoe Islands
Biscoe Islands is a series of islands, of which the principal ones are Renaud, Lavoisier (named ''Serrano'' by Chile and ''Mitre'' by Argentina), Watkins, Krogh, Pickwick and Rabot, lying parallel to the west coast of Graham Land and extending between Southwind Passage on the northeast and Matha Strait on the southwest. Another group of islands are the Adolph Islands. The islands are named for John Biscoe, the commander of a British expedition which explored the islands in February 1832.

The group comprises St. Brigid, Irving, St. Isidore, Chakarov, Hervé, Montojo, Alcheh, Leppe and Bedford Islands. The islands were mapped from air photos by the Falkland Islands and Dependencies Aerial Survey Expedition (1956–57), and named by the UK Antarctic Place-Names Committee for Sir Joseph Barcroft Sir Joseph Barcroft (26 July 1872 – 21 March 1947) was a British physiologist best known for his studies of the oxygenation of blood.

Bulgarians In South America
Bulgarians (Spanish and pt, búlgaros) have been settling in South America ( bg, Южна Америка, ''Yuzhna Amerika'') as economic emigrants since the late 19th century. Their presence has been documented in Uruguay since 1905, in Argentina since 1906 and in Brazil since the early 20th century. History and distribution The Bulgarian diaspora in South America is strongest in Argentina, where 40,000 people of Bulgarian descent are thought to live, the diaspora itself assessing its size to be at least 80,000. However, according to official data, only around 3,000 people have declared Bulgarian nationality in Argentina. Bulgarians mainly live in Buenos Aires, Berisso, Mar del Plata, Presidencia Roque Sáenz Peña, Las Breñas and Comodoro Rivadavia. The most significant wave of emigration was in the 1920s, following World War I, when over 20,000 Bulgarians (mostly from northern Bulgaria: around Veliko Tarnovo, Lovech, Pleven, Vratsa and Targovishte) settled in Argentina.

Watkins Island
Watkins Island is a low lying, ice-covered island long, lying southwest of Lavoisier Island in the Biscoe Islands. The island was first mapped by the French Antarctic Expedition under Jean-Baptiste Charcot, 1903–05 and 1908–10, but remained unnamed until resighted by the BGLE under Rymill, 1934–1937. He gave the name Mikkelsen Island after Ejnar Mikkelsen, Danish Arctic explorer. In applying the name, Rymill was unaware of the existence of Mikkelsen Islands southwestward, named in 1908–1910 by Charcot. To avoid confusion of the two, the UK-APC recommended in 1952 that the Rymill naming be amended. The new name, Watkins Island, commemorates Gino Watkins, leader of the British Arctic Air Route Expedition The British Arctic Air Route Expedition (BAARE) was a privately funded expedition to the east coast and interior of the island of Greenland from 1930 to 1931. Led by Gino Watkins, it aimed to improve maps and charts of poorly surveyed sections of ..., 1930–19 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Islands Of The Biscoe 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 ...
