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] |
Beaufort Sea
The Beaufort Sea ( ; ) is a marginal sea of the Arctic Ocean, located north of the Northwest Territories, Yukon, and Alaska, and west of the Canadian Arctic Archipelago. The sea is named after Sir Francis Beaufort, a Hydrography, hydrographer. The Mackenzie River, the longest in Canada, empties into the Canadian part of the Beaufort Sea west of Tuktoyaktuk, which is one of the few permanent settlements on the sea's shores. The sea, characterized by severe climate, is frozen over most of the year. Historically, only a narrow pass up to opened in August–September near its shores, but recently due to climate change in the Arctic the ice-free area in late summer has greatly enlarged. Until recently, the Beaufort Sea was known as an important reservoir for the replenishment of Arctic sea ice. Sea ice would often rotate for several years in the Beaufort Gyre, the dominant ocean current of the Beaufort Sea, growing into sturdy and thick multi-year ice. Claims that the seacoast was p ...

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 ...

Morane (French Polynesia)
Morane is an uninhabited small isolated atoll of the Tuamotu Archipelago in French Polynesia. It is located 153 km southwest of Maria Est, its closest neighbour. Morane Atoll is the southernmost atoll of the Tuamotus proper. It measures 5.8 km in length, 3.5 km in width and has a land area of 2.85 km2. The lagoon has an area of 11 km2 and has no passes. The islands on its reef are covered with screw pine (''Pandanus'') and coconut trees. History The first recorded westerner to sight Morane Atoll was Captain Samuel Grimwood of the ''Discoverer'', owned by the naturalist Hugh Cuming, on 15 January 1828. Its original name was Grimwood's Island. Cited as such in the "Pacific Island Names" atlas published by Bishop Museum Press, Hawaii, in 1986. Another source gives it the name Cadmus, after the whaler . The source gives the captain's name as Cary, and the year as 1832. Actually, ''Cadmus'', Mayhew, master, was wrecked there on 4 August 1842. Administration ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tenararo
Tenararo is the smallest atoll in the Acteon Group in the southeastern part of the Tuamotu Islands in French Polynesia. It is administratively a part of the Gambier Islands. It is uninhabited. Geography Tenararo is located west of Vahanga, the nearest island, west of the Gambier Islands and southeast of Tahiti. It is a circular atoll with a land area of and a land area of . The atoll has a landing place on its NW side between the small boulders which encumber the reef. There is no entrance to the lagoon. History The first recorded sighting of this atoll was made during the Spanish expedition of the Portuguese navigator Pedro Fernández de Quirós on 5 February 1606 under the name ''Las Cuatro Coronadas'' (the "four crowned" (by coconut palms)), however these observations were not fully documented. As such, the first unambiguous approach to the island was made on 14 March 1828 by the explorer Hugh Cuming in his ship the Discoverer captained by Samuel Grimwood. The next visit ...

Pukarua
Pukarua, sometimes also listed as "Pukaruha" (especially on French maps), is a coral atoll in the eastern Tuamotu Archipelago. The nearest atoll, Reao, is located 48 km east-southeast of Pukarua. Pukarua Atoll is 17 km long and its maximum width is 4.5 km. It has a long island on its northeastern reef, shaped somewhat like a fish hook, as well as a number of small islands. The atoll is surrounded by a coral reef without a proper passage. There is a pier from which small to medium-sized ships can be launched. The only village is Marautagaroa, populated by about 100 inhabitants. The atoll's lagoon is interesting for snorkelers because of the presence of giant clams. History Pukarua Atoll was first visited by Europeans in 1797, when British mariner James Wilson was sailing from Tongatapu to the Marquesas on the ship ''Duff''. He found Pukarua uninhabited, but saw the tokens of former occupancy. Wilson named Pukarua "Searle Island" after a friend he had in the ...

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] |
