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] |
Farasan Islands
The Farasan Islands (; transliterated: ) are a small group of coral islands approximately 40 km off the coast of Jizan in the Red Sea, belonging to Saudi Arabia. The government provides free ferry rides twice a day to Farasan Islands from Jizan Port. The largest island of the archipelago is Farasan Island; others include Sajid Island and Zufaf Island. The islands are a popular tourist destination. In recent years the Saudi government has tried to increase the tourism quality and worth (as part of a larger tourism drive in the country) of the Islands in order to attract even more visitors. History In the 1st century AD, the islands were known as ''Portus Ferresanus''. A Latin inscription dating from 144 AD has been found on the island which attests to the construction of a Roman garrison. It is believed that the islands may have been attached to the Roman province of Arabia Felix, before being transferred to Aegyptus some time before 144 AD. This fact would make the ...

Red Sea
The Red Sea is a sea inlet of the Indian Ocean, lying between Africa and Asia. Its connection to the ocean is in the south, through the Bab-el-Mandeb Strait and the Gulf of Aden. To its north lie the Sinai Peninsula, the Gulf of Aqaba, and the Gulf of Suez—leading to the Suez Canal. It is underlain by the Red Sea Rift, which is part of the Great Rift Valley. The Red Sea has a surface area of roughly , is about long, and wide at its widest point. It has an average depth of , and in the central Suakin Trough, it reaches its maximum depth of . Approximately 40% of the Red Sea is quite shallow at less than deep and about 25% is less than deep. The extensive shallow shelves are noted for their marine life and corals. More than 1,000 invertebrate species and 200 types of soft and hard coral live in the sea. The Red Sea is the world's northernmost tropical sea and has been designated a Global 200 ecoregion.

International Recognition Of Abkhazia And South Ossetia
Abkhazia and South Ossetia are separatist regions of Georgia in the Caucasus. Most countries recognise them as part of Georgia, while Russia, Venezuela, Nicaragua, Nauru, and Syria regard them as independent. Russia's initial recognition of the independence of Abkhazia and South Ossetia occurred in the aftermath of the Russo-Georgian War in 2008. The government of Georgia considers the republics to be Russian-occupied territories. Abkhazia and South Ossetia were once recognised by up to seven UN member states, until Tuvalu withdrew its recognition of both in 2014, and Vanuatu clarified the status of their recognitions. Vanuatu reconfirmed in 2019 it supports Georgian territorial integrity including the two disputed territories. Abkhazia and South Ossetia recognise each other, and also have some recognition from non-UN member states. History South Ossetia declared independence from Georgia during the 1991–1992 South Ossetia War on 29 May 1992, with its Constitution ref ...

White Sea
The White Sea (; Karelian language, Karelian and ; ) is a southern inlet of the Barents Sea located on the northwest coast of Russia. It is surrounded by Karelia to the west, the Kola Peninsula to the north, and the Kanin Peninsula to the northeast. The whole of the White Sea is under Russian sovereignty and considered to be part of the internal waters of Russia.A. D. Dobrovolskyi and B. S. Zalogi"Seas of USSR. White Sea" Moscow University (1982) (in Russian) Administratively, it is divided between the Arkhangelsk Oblast, Arkhangelsk and Murmansk Oblast, Murmansk oblasts and the Republic of Karelia. The Port of Arkhangelsk, major port of Arkhangelsk is located on the White Sea. For much of Russia's history this was Russia's main centre of international maritime trade, conducted by the Pomors ("seaside settlers") from Kholmogory, Arkhangelsk Oblast, Kholmogory. In the modern era it became an important Soviet Union, Soviet naval and submarine base. The White Sea–Baltic Canal co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barents Sea
The Barents Sea ( , also ; , ; ) is a marginal sea of the Arctic Ocean, located off the northern coasts of Norway and Russia and divided between Norwegian and Russian territorial waters.World Wildlife Fund, 2008. It was known earlier among Russians as the Northern Sea, Pomorsky Sea or Murman Sea ("Norse Sea"); the current name of the sea is after the historical Netherlands, Dutch navigator Willem Barentsz. The Barents Sea is a rather shallow Continental shelf, shelf sea with an average depth of , and it is an important site for both fishing and hydrocarbon exploration.O. G. Austvik, 2006. It is bordered by the Kola Peninsula to the south, the shelf edge towards the Norwegian Sea to the west, the archipelagos of Svalbard to the northwest, Franz Josef Land to the northeast and Novaya Zemlya to the east. The islands of Novaya Zemlya, an extension of the northern end of the Ural Mountains, separate the Barents Sea from the Kara Sea. Although part of the Arctic Ocean, the Barents Sea ...

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] |
