Prime Meridian
A prime meridian is an arbitrarily chosen meridian (geography), meridian (a line of longitude) in a geographic coordinate system at which longitude is defined to be 0°. On a spheroid, a prime meridian and its anti-meridian (the 180th meridian in a degree (angle), 360°-system) form a great ellipse. This divides the body (e.g. Earth) into hemispheres of Earth, two hemispheres: the Eastern Hemisphere and the Western Hemisphere (for an east-west notational system). For Earth's prime meridian, various conventions have been used or advocated in different regions throughout history. Earth's current international standard prime meridian is the IERS Reference Meridian. It is derived, but differs slightly, from the Prime meridian (Greenwich), Greenwich Meridian, the previous standard. Longitudes for the Earth and Moon are measured from their prime meridian (at 0°) to 180° east and west. For all other Solar System bodies, longitude is measured from 0° (their prime meridian) to 360� ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

List Of Antarctic Territorial Claims
Seven sovereign states – Argentina, Australia, Chile, France, New Zealand, Norway, and the United Kingdom – have made eight territorial claims in Antarctica. These countries have tended to place their Antarctic scientific observation and study facilities within their respective claimed territories; however, a number of such facilities are located outside of the area claimed by their respective countries of operation, and countries without claims such as Spain, China, India, Italy, Japan, Pakistan, Russia, South Africa ( SANAE), Poland, and the United States have constructed research facilities within the areas claimed by other countries. There are overlaps among the territories claimed by Argentina, Chile, and the United Kingdom. History Spanish claims According to Argentina and Chile, the Spanish Crown had claims on Antarctica. The ''capitulación'' (governorship) granted to the conquistador Pedro Sánchez de la Hoz in 1539 by the King of Spain, Charles V, explicitly ...

Queen Maud Land
Queen Maud Land () is a roughly region of Antarctica Territorial claims in Antarctica, claimed by Norway as a dependent territory. It borders the claimed British Antarctic Territory 20th meridian west, 20° west, specifically the Caird Coast, Coats Land on the West, and the Australian Antarctic Territory 45th meridian east, 45° east, specifically Enderby Land on the East. In addition, a small unclaimed area from 1939 was annexed in June 2015. Positioned in East Antarctica, it makes out about one-fifth of the continent, and is named after the Norwegian Maud of Wales, Queen Maud (1869–1938). In 1930, the Norwegian Hjalmar Riiser-Larsen was the first person known to have set foot in the territory. On 14 January 1939, the territory was claimed by Norway. On 23 June 1961, Queen Maud Land became part of the Antarctic Treaty System, making it a demilitarised zone. It is one of dependencies of Norway, two Antarctic claims made by Norway, the other being Peter I Island. They are adm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tristan Da Cunha
Tristan da Cunha (), colloquially Tristan, is a remote group of volcano, volcanic islands in the South Atlantic Ocean. It is one of three constituent parts of the British Overseas Territories, British Overseas Territory of Saint Helena, Ascension and Tristan da Cunha, with its own constitution. The territory consists of the inhabited island Tristan da Cunha, which has a diameter of roughly and an area of ; the wildlife reserves of Gough Island and Inaccessible Island; and the smaller, uninhabited Nightingale Islands. , the main island had 250 permanent inhabitants, who all carry British Overseas Territories citizenship. The other islands are uninhabited, except for the South African personnel of a weather station on Gough Island. As there is no airstrip on the island, the only way of travelling to or from Tristan is by ship. There are six-day journeys from Cape Town, South Africa, and some cruises offered departing from Ushuaia, Argentina. History Discovery The islan ...

Inaccessible Island
Inaccessible Island is a volcanic island located in the South Atlantic Ocean, south-west of Tristan da Cunha. Its highest point, Swale's Fell, reaches , and the island is in area. The volcano was last active approximately one million years ago and is now extinct. Inaccessible Island is a part of the archipelago of Tristan da Cunha, which is a part of the overseas territory of the United Kingdom known as Saint Helena, Ascension and Tristan da Cunha. Tristan da Cunha itself is accessible only by sea via a seven-day voyage from Cape Town, South Africa. The harbour on Inaccessible Island allows access for only a few days of the year. Access to Inaccessible Island must be granted by the local government office. Geography The island is approximately to the southwest of the main island of the Tristan da Cunha archipelago. Mostly desolate and inhospitable, the island has a few small, rocky beaches that host penguins and subantarctic fur seals. Generations of sailors were wary ...

Turtle Islands, Sierra Leone
The Turtle Islands are in the Atlantic Ocean, located west of Sherbro Island in the Southern Province of Sierra Leone. Of the eight islands, seven are inhabited. Sherbro people are the predominant ethnic group. This eight-island archipelagos expands in a zone of over shallow waters and white sand banks. Yele, Bakie, Bumpetuk, Chepo, Hoong, Mut, Nyangei and Sei are the names of the islands. Economic activities Fishing is the main economic activity. Coconut products and tourism may contribute to the income in a lesser extent. Erosion is an issue especially on Nyangai and efforts to stem it by planting mangroves has been stymied by goats eating them and people using the wood for fires. Traditions Turtle Islands is a remote destination. The fishing communities have preserved their faith and traditions in a vivid manner. Sherbros are very social and spend their evenings in groups, drinking and singing traditional songs focused on bravery and romance. One of the eight islands, Hoong, ...

Western Sahara
Western Sahara is a territorial dispute, disputed territory in Maghreb, North-western Africa. It has a surface area of . Approximately 30% of the territory () is controlled by the Sahrawi Arab Democratic Republic (SADR); the remaining 70% is military occupation, occupied and administered by neighboring Morocco. It is the most sparsely populated territory in Africa and the list of countries and dependencies by population density, second most sparsely populated territory in the world, mainly consisting of desert flatlands. The population is estimated at 618,600. Nearly 40% of that population lives in Morocco-controlled Laayoune, the largest city of Western Sahara. Previously occupied by Spain (Spanish Colony) as the Spanish Sahara until 1975, Western Sahara has been on the United Nations list of non-self-governing territories since 1963 after a Moroccan demand. In 1965, the United Nations General Assembly adopted a resolution on Western Sahara, asking Spain to decolonization, de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great Circle
In mathematics, a great circle or orthodrome is the circular intersection of a sphere and a plane passing through the sphere's center point. Discussion Any arc of a great circle is a geodesic of the sphere, so that great circles in spherical geometry are the natural analog of straight lines in Euclidean space. For any pair of distinct non- antipodal points on the sphere, there is a unique great circle passing through both. (Every great circle through any point also passes through its antipodal point, so there are infinitely many great circles through two antipodal points.) The shorter of the two great-circle arcs between two distinct points on the sphere is called the ''minor arc'', and is the shortest surface-path between them. Its arc length is the great-circle distance between the points (the intrinsic distance on a sphere), and is proportional to the measure of the central angle formed by the two points and the center of the sphere. A great circle is the largest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Longitude
Longitude (, ) is a geographic coordinate that specifies the east- west position of a point on the surface of the Earth, or another celestial body. It is an angular measurement, usually expressed in degrees and denoted by the Greek letter lambda (λ). Meridians are imaginary semicircular lines running from pole to pole that connect points with the same longitude. The prime meridian defines 0° longitude; by convention the International Reference Meridian for the Earth passes near the Royal Observatory in Greenwich, south-east London on the island of Great Britain. Positive longitudes are east of the prime meridian, and negative ones are west. Because of the Earth's rotation, there is a close connection between longitude and time measurement. Scientifically precise local time varies with longitude: a difference of 15° longitude corresponds to a one-hour difference in local time, due to the differing position in relation to the Sun. Comparing local time to an absol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Pole
The South Pole, also known as the Geographic South Pole or Terrestrial South Pole, is the point in the Southern Hemisphere where the Earth's rotation, Earth's axis of rotation meets its surface. It is called the True South Pole to distinguish from the south magnetic pole. The South Pole is by definition the southernmost point on the Earth, lying antipode (geography), antipodally to the North Pole. It defines geodetic latitude 90° South, as well as the direction of true south. At the South Pole all directions point North; all lines of longitude converge there, so its longitude can be defined as any degree value. No time zone has been assigned to the South Pole, so any time can be used as the local time. Along tight latitude circles, clockwise is east and counterclockwise is west. The South Pole is at the center of the Southern Hemisphere. Situated on the continent of Antarctica, it is the site of the United States Amundsen–Scott South Pole Station, which was established in 19 ...
