140th Meridian West
The meridian 140° west of Greenwich is a line of longitude that extends from the North Pole across the Arctic Ocean, North America, the Pacific Ocean, the Southern Ocean, and Antarctica to the South Pole. The line is the divider in the area of warning responsibility between the National Hurricane Center and the Central Pacific Hurricane Center in the north Pacific Ocean. The 140th meridian west forms a great circle with the 40th meridian east. From Pole to Pole Starting at the North Pole and heading south to the 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.

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] |
40th Meridian East
The meridian 40° east of Greenwich is a line of longitude that extends from the North Pole across the Arctic Ocean, Europe, Asia, Africa, the Indian Ocean, the Southern Ocean, and Antarctica to the South Pole. The meridian is used in some contexts to delineate Europe or what is associated with the continent of Europe as an easternmost limit, e.g. to qualify for membership of the European Broadcasting Union.

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 ...

Ua Pou
Ua Pou (, North Marquesan: ''’uapou'') is the third-largest of the Marquesas Islands, in French Polynesia, an overseas territory of France in the Pacific Ocean. History Pre-European history Ua Pou is the only major island that was unified under a single monarch prior to the arrival of European explorers. Prior to the island's unification, reportedly about 1585, there is evidence that the tribes of Ua Pou were sometimes united in war with the tribes of Te I'i on Nuku Hiva against those of Tai Pi Vai. Despite the fact that tribes from both the eastern and western halves of Ua Pou were often united in war against each other, however, it appears that such differences among them were not considered when members of tribes from either side of the island sought refuge among the tribes of Te I'i on Nuku Hiva. The early Polynesian settlers of Ua Pou lived under rock overhangs, as excavations from 1982 onwards at the Anapua rock shelter, not far from the village of Hakatao in th ...

Nuku Hiva
Nuku Hiva (sometimes spelled Nukahiva or Nukuhiva) is the largest of the Marquesas Islands in French Polynesia, an overseas country of France in the Pacific Ocean. It was formerly also known as ''Île Marchand'' and ''Madison Island''. Herman Melville wrote his book '' Typee'' based on his experiences in the Taipivai valley in the eastern part of Nuku Hiva. Robert Louis Stevenson's first landfall on his voyage on the ''Casco'' was at Hatihe'u, on the north side of the island, in 1888. Geography Coast Western Nuku Hiva is characterized by a steep but fairly regular coastline, indented occasionally by small bays, leading to deep valleys, which in turn lead into the interior. There are no villages on the western side. The coastline of the eastern part of the island has few places to land by sea and takes the brunt of the ocean swells. The northern side, in contrast, is indented by deep bays, the largest of which are Anahō and Hatihe'u. A third bay, 'A'akapa, is smaller and ...

Yakutat Bay
Yakutat Bay ( Lingít: ''Yaakwdáat G̱eeyí'') is a bay in the U.S. state of Alaska, extending southwest from Disenchantment Bay to the Gulf of Alaska. "Yakutat" is a Tlingit name reported as "Jacootat" and "Yacootat" by Yuri Lisyansky in 1805. Yakutat Bay was the epicenter of two major earthquakes on September 10, 1899, a magnitude 7.4 foreshock and a magnitude 8.0 main shock, 37 minutes apart. The Shelikhov-Golikov company (precursor of the Russian-American Company), under the management of Alexander Andreyevich Baranov, founded a settlement in Yakutat Bay in 1795. It was known as New Russia, Yakutat Colony, or Slavorossiya. Other names Yakutat Bay has had various names. *James Cook called it "Bering Bay".Khlebnikov, K.T., 1973, Baranov, Chief Manager of the Russian Colonies in America, Kingston: The Limestone Press, * Jean-François de La Pérouse, who visited it in 1786, named it "Baie de Monti" for one of his officers. *The same year, Captain Nathaniel Por ...

Alaska
Alaska ( ) is a non-contiguous U.S. state on the northwest extremity of North America. Part of the Western United States region, it is one of the two non-contiguous U.S. states, alongside Hawaii. Alaska is also considered to be the northernmost, westernmost, and easternmost (the Aleutian Islands cross the 180th meridian into the eastern hemisphere) state in the United States. It borders the Canadian territory of Yukon and the province of British Columbia to the east. It shares a western maritime border, in the Bering Strait, with Russia's Chukotka Autonomous Okrug. The Chukchi and Beaufort Seas of the Arctic Ocean lie to the north, and the Pacific Ocean lies to the south. Technically, it is a semi-exclave of the U.S., and is the largest exclave in the world. Alaska is the largest U.S. state by area, comprising more total area than the following three largest states of Texas, California, and Montana combined, and is the seventh-largest subnational division i ...

Yukon
Yukon () is a Provinces and territories of Canada, territory of Canada, bordering British Columbia to the south, the Northwest Territories to the east, the Beaufort Sea to the north, and the U.S. state of Alaska to the west. It is Canada’s westernmost territory and the smallest territory by land area. As of the 2021 Canadian census, 2021 census, Yukon is the middle territory in terms of population, but the most densely populated. Yukon has an estimated population of 47,126 as of 2025. Whitehorse, the territorial capital, is the largest settlement. Yukon was History of the Northwest Territories, split from the Northwest Territories by a federal statute in 1898 as the Yukon Territory. The current governing legislation is a new statute passed by the federal Parliament in 2002, the ''Yukon Act''. That act established Yukon as the territory's official name, although Yukon Territory remains in popular usage. Canada Post uses the territory's internationally approved postal abbrevia ...

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 ...

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] |
