Chuckchi Sea
The Chukchi Sea (, ), sometimes referred to as the Chuuk Sea, Chukotsk Sea or the Sea of Chukotsk, is a marginal sea of the Arctic Ocean. It is bounded on the west by the Long Strait, off Wrangel Island, and in the east by Point Barrow, Alaska, beyond which lies the Beaufort Sea. The Bering Strait forms its southernmost limit and connects it to the Bering Sea and the Pacific Ocean. The principal port on the Chukchi Sea is Uelen in Russia. The International Date Line crosses the Chukchi Sea from northwest to southeast. It is displaced eastwards to avoid Wrangel Island as well as the Chukotka Autonomous Okrug on the Russian mainland. Etymology In 1928, during hydrographic observations, the Norwegian polar explorer Harald Sverdrup (oceanographer), Harald Sverdrup discovered that the sea lying between Point Barrow and Wrangel Island was very different from the sea between the New Siberian Islands and Wrangel Island and therefore should be separated from the East Siberian Sea. It was d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North Asia
North Asia or Northern Asia () is the northern region of Asia, which is defined in geography, geographical terms and consists of three federal districts of Russia: Ural Federal District, Ural, Siberian Federal District, Siberian, and the Far Eastern Federal District, Far Eastern. North Asia is bordered by the Arctic Ocean to its north; by Eastern Europe to its west; by Central Asia and East Asia to its south; and by the Pacific Ocean and Northern America to its east. It covers an area of , or 8.8% of Earth's total land area; and is the largest subregion of Asia by area, occupying approx. 29.4% of Asia's land area, but is also the least populated, with a population of around 37 million, accounting for merely 0.74% of Asia's population. Topographically, the region is dominated by the Eurasian Plate, except for its eastern part, which lies on the North American Plate, North American, Amurian Plate, Amurian, and Okhotsk Plates. It is divided by three major plains: the West Siberian ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Date Line
The International Date Line (IDL) is the line extending between the South and North Poles that is the boundary between one calendar day and the next. It passes through the Pacific Ocean, roughly following the 180.0° line of longitude and deviating to pass around some territories and island groups. Crossing the date line eastbound decreases the date by one day, while crossing the date line westbound increases the date. The line is a cartographic convention and is not defined by international law. This has made it difficult for cartographers to agree on its precise course and has allowed countries through whose waters it passes to move it at times for their convenience. Geography Circumnavigating the globe People traveling westward around the world must set their clocks: *Back by one hour for every 15° of longitude crossed, and *Forward by 24 hours upon crossing the International Date Line. People traveling eastward must set their clocks: *Forward by one hour for e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Walrus
The walrus (''Odobenus rosmarus'') is a large pinniped marine mammal with discontinuous distribution about the North Pole in the Arctic Ocean and subarctic seas of the Northern Hemisphere. It is the only extant species in the family Odobenidae and genus ''Odobenus''. This species is subdivided into two subspecies: the Atlantic walrus (''O. r. rosmarus''), which lives in the Atlantic Ocean, and the Pacific walrus (''O. r. divergens''), which lives in the Pacific Ocean. Adult walrus are characterised by prominent tusks and whiskers, and considerable bulk: adult males in the Pacific can weigh more than and, among pinnipeds, are exceeded in size only by the two species of elephant seals. Walrus live mostly in shallow waters above the continental shelves, spending significant amounts of their lives on the sea ice looking for benthic bivalve molluscs. Walruses are relatively long-lived, social animals, and are considered to be a " keystone species" in the Arctic marine regio ...

Chukchi People
The Chukchi, or Chukchee (, ''ḷygʺoravètḷʹèt, o'ravètḷʹèt''), are a Siberian ethnic group native to the Chukchi Peninsula, the shores of the Chukchi Sea and the Bering Sea region of the Arctic Ocean all within modern Russia. They speak the Chukchi language. The Chukchi originated from the people living around the Okhotsk Sea. According to several studies on genomic research conducted from 2014 to 2018, the Chukchi are the closest Asian relatives of the indigenous peoples of the Americas as well as of the Ainu people, being the descendants of settlers who neither crossed the Bering Strait nor settled the Japanese archipelago. Cultural history The majority of Chukchi reside within Chukotka Autonomous Okrug, but some also reside in the neighboring Sakha Republic to the west, Magadan Oblast to the southwest, and Kamchatka Krai to the south. Some Chukchi also reside in other parts of Russia, as well as in Europe and North America. The total number of Chukchi in t ...

Siberia
Siberia ( ; , ) is an extensive geographical region comprising all of North Asia, from the Ural Mountains in the west to the Pacific Ocean in the east. It has formed a part of the sovereign territory of Russia and its predecessor states since the lengthy conquest of Siberia, which began with the fall of the Khanate of Sibir in 1582 and concluded with the annexation of Chukotka in 1778. Siberia is vast and sparsely populated, covering an area of over , but home to roughly a quarter of Russia's population. Novosibirsk, Krasnoyarsk, and Omsk are the largest cities in the area. Because Siberia is a geographic and historic concept and not a political entity, there is no single precise definition of its territorial borders. Traditionally, Siberia spans the entire expanse of land from the Ural Mountains to the Pacific Ocean, with the Ural River usually forming the southernmost portion of its western boundary, and includes most of the drainage basin of the Arctic Ocean.

Herald Island (Arctic)
Herald Island (, ''Ostrov Gerald'') is a small, isolated Russian island in the Chukchi Sea, east of Waring Point, Wrangel Island. It rises in sheer cliffs, making it quite inaccessible, either by ship or by plane. The only bit of accessible shoreline is at its northwestern point, where the cliffs have crumbled into piles of loose rocks and gravel. Its area is and the maximum height above sea level is . The island is unglaciated and uninhabited. It is the northeasternmost point of land in the world. Herald Island belongs administratively to the Chukotka Autonomous Okrug of the Russian Federation. Along with Wrangel Island, Herald Island has been part of the Wrangel Island Wildlife Preserve, a Russian National Park, since 1976. Cape Dmitrieva on Herald Island, marks the easternmost limits of the nature reserve. Herald Island is named after survey vessel HMS Herald (1824), HMS ''Herald'', from which the island was discovered in 1849. Geology Herald Island is composed of sedimen ...

Hope Basin
The Hope Basin is a geological feature of the Chukchi Sea Shelf. It lies off the Chukchi Sea coast of Alaska. Its area extends from the outer continental shelf of the Seward Peninsula for about westwards off the coast of Chukotka towards Wrangel Island. The Hope Basin is limited on its northeastern side by the Herald Arch (Herald Thrust), a basement uplift cored by Cretaceous thrust faults. The Herald Arch is named after Herald Island.

East Siberian Sea
The East Siberian Sea (; ) is a marginal sea in the Arctic Ocean. It is located between the Arctic Cape to the north, the coast of Siberia to the south, the New Siberian Islands to the west and Cape Billings, close to Chukchi Peninsula, Chukotka, and Wrangel Island to the east. This sea borders on the Laptev Sea to the west and the Chukchi Sea to the east. This sea is one of the least studied in the Arctic area. It is characterized by severe climate, low water salinity, and a scarcity of flora, fauna and human population, as well as shallow depths (mostly less than 50 m), slow sea currents, low tides (below 25 cm), frequent fogs, especially in summer, and an abundance of ice fields which fully melt only in August–September. The sea shores were inhabited for thousands of years by indigenous tribes of Yukaghirs, Chukchi people, Chukchi and then Evens and Evenks, which were engaged in fishing, hunting and reindeer husbandry. They were then absorbed by Yakuts and later by Russi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New Siberian Islands
The New Siberian Islands (; ) are an archipelago in the Extreme North of Russia, to the north of the East Siberian coast between the Laptev Sea and the East Siberian Sea north of the Sakha (Yakutia) Republic, of whose Bulunsky District they are administratively a part. History The first news about the existence of the New Siberian Islands was brought by a Cossack, Yakov Permyakov, in the beginning of the 18th century. In 1712, a Cossack unit led by M. Vagin reached the Great Lyakhovsky Island. In 1809–10 Yakov Sannikov and Matvei Gedenschtrom went to the New Siberian Islands on a cartographic expedition. Sannikov reported the sighting of a "new land" north of Kotelny in 1811. This became the myth of ''Zemlya Sannikova'' or '' Sannikov Land''.Markham, Albert Hastings ''Arctic Exploration'', 1895 In 1886, Russian polar explorer and scientist Eduard Toll, during his first visit to the New Siberian Islands, thought that he had seen an unknown land north of Kotelny Island.
