Sea Of Okhotsk
The Sea of Okhotsk ( rus, Охо́тское мо́ре, Ohótskoye móre ; ja, オホーツク海, Ohōtsuku-kai) is a marginal sea of the western Pacific Ocean. It is located between Russia's Kamchatka Peninsula on the east, the Kuril Islands on the southeast, Japan's island of Hokkaido on the south, the island of Sakhalin along the west, and a stretch of eastern Siberian coast along the west and north. The northeast corner is the Shelikhov Gulf. The sea is named after the Okhota river, which in turn named after the Even word () meaning "river". Geography The Sea of Okhotsk covers an area of , with a mean depth of and a maximum depth of . It is connected to the Sea of Japan on either side of Sakhalin: on the west through the Sakhalin Gulf and the Gulf of Tartary; on the south through the La Pérouse Strait. In winter, navigation on the Sea of Okhotsk is impeded by ice floes. Ice floes form due to the large amount of freshwater from the Amur River, lowering the salinity o ...

Magadan
Magadan ( rus, Магадан, p=məɡɐˈdan) is a port town and the administrative center of Magadan Oblast, Russia, located on the Sea of Okhotsk in Nagayev Bay (within Taui Bay) and serving as a gateway to the Kolyma region. History Magadan was founded in 1930 in the Ola (river) valley,Vazhenin, p. 4 near the settlement of Nagayevo. During the Stalin era, Magadan was a major transit center for political prisoners sent to forced labour camps. From 1932 to 1953, it was the administrative centre of the Dalstroy organisation—a vast forced-labour gold-mining operation and forced-labour camp system. The first director of Dalstroy was Eduard Berzin, who between 1932 and 1937 established the infrastructure of the forced labour camps in Magadan. Berzin was executed in 1938 by Stalin, towards the end of the Great Purge. The town later served as a port for exporting gold and other metals mined in the Kolyma region. Its size and population grew quickly as facilities were ra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North Asia
North Asia or Northern Asia, also referred to as Siberia, is the northern region of Asia, which is defined in geographical terms and is coextensive with the Asian part of Russia, and consists of three Russian regions east of the Ural Mountains: Ural, Siberia, and the Russian Far East. North Asia is bordered by the Arctic Ocean to its north; by Eastern Europe to its west; by Central and East Asia to its south; and by the Pacific Ocean and North 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, but is also the least populated, with a population of around 33 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, Amurian, and Okhotsk Plates. It is divided by three major plains: the West Siberian Plain, Central Siberian Plateau, and Verhoyansk-Chukotka collision zone. The Uralia ...

Kuril Islands Dispute
The Kuril Islands dispute, known as the Northern Territories dispute in Japan, is a territorial dispute between Japan and Russia over the ownership of the four southernmost Kuril Islands. The Kuril Islands are a chain of islands that stretch between the Japanese island of Hokkaido at their southern end and the Russian Kamchatka Peninsula at their northern end. The islands separate the Sea of Okhotsk from the Pacific Ocean. The four disputed islands, like other islands in the Kuril chain that are not in dispute, were unilaterally annexed by the Soviet Union following the Kuril Islands landing operation at the end of World War II. The disputed islands are under Russian administration as the South Kuril District and part of Kuril District of the Sakhalin Oblast (Сахалинская область, ''Sakhalinskaya oblast''). They are claimed by Japan, which refers to them as its Northern Territories or Southern Chishima, and considers them part of the Nemuro Subprefecture of ...

Chum Salmon
The chum salmon (''Oncorhynchus keta''), also known as dog salmon or keta salmon, is a species of anadromous salmonid fish from the genus '' Oncorhynchus'' (Pacific salmon) native to the coastal rivers of the North Pacific and the Beringian Arctic, and is often marketed under the trade name silverbrite salmon in North America. The English name "chum salmon" comes from the Chinook Jargon term ''tzum'', meaning "spotted" or "marked"; while ''keta'' in the scientific name comes from Russian, which in turn comes from the Evenki language of Eastern Siberia. In Japan, chum salmon is also known as the , or simply , while historically it was known in ''kun'yomi'' as up until the Meiji period. In Greater China, it is known academically as the " hook-snout salmon" ( zh, 钩吻鲑), but is more often called the ''damaha'' fish (), which is borrowed from ''dawa ịmaχa'', the Nanai name of the fish used by the Hezhe minority in northern Northeast China.

Salmon
Salmon () is the common name for several list of commercially important fish species, commercially important species of euryhaline ray-finned fish from the family (biology), family Salmonidae, which are native to tributary, tributaries of the North Atlantic (genus ''Salmo'') and North Pacific (genus ''Oncorhynchus'') basin. Other closely related fish in the same family include trout, Salvelinus, char, Thymallus, grayling, Freshwater whitefish, whitefish, lenok and Hucho, taimen. Salmon are typically fish migration, anadromous: they hatch in the gravel stream bed, beds of shallow fresh water streams, migrate to the ocean as adults and live like sea fish, then return to fresh water to reproduce. However, populations of several species are restricted to fresh water throughout their lives. Folklore has it that the fish return to the exact spot where they hatched to spawn (biology), spawn, and tracking studies have shown this to be mostly true. A portion of a returning salmon run ma ...

Freezing Point
The melting point (or, rarely, liquefaction point) of a substance is the temperature at which it changes state from solid to liquid. At the melting point the solid and liquid phase exist in equilibrium. The melting point of a substance depends on pressure and is usually specified at a standard pressure such as 1 atmosphere or 100 kPa. When considered as the temperature of the reverse change from liquid to solid, it is referred to as the freezing point or crystallization point. Because of the ability of substances to supercool, the freezing point can easily appear to be below its actual value. When the "characteristic freezing point" of a substance is determined, in fact, the actual methodology is almost always "the principle of observing the disappearance rather than the formation of ice, that is, the melting point." Examples For most substances, melting and freezing points are approximately equal. For example, the melting point ''and'' freezing point of mercury is . Ho ...

Salinity
Salinity () is the saltiness or amount of salt dissolved in a body of water, called saline water (see also soil salinity). It is usually measured in g/L or g/kg (grams of salt per liter/kilogram of water; the latter is dimensionless and equal to ‰). Salinity is an important factor in determining many aspects of the chemistry of natural waters and of biological processes within it, and is a thermodynamic state variable that, along with temperature and pressure, governs physical characteristics like the density and heat capacity of the water. A contour line of constant salinity is called an ''isohaline'', or sometimes ''isohale''. Definitions Salinity in rivers, lakes, and the ocean is conceptually simple, but technically challenging to define and measure precisely. Conceptually the salinity is the quantity of dissolved salt content of the water. Salts are compounds like sodium chloride, magnesium sulfate, potassium nitrate, and sodium bicarbonate which dissolve into ions ...

Amur River
The Amur (russian: река́ Аму́р, ), or Heilong Jiang (, "Black Dragon River", ), is the world's List of longest rivers, tenth longest river, forming the border between the Russian Far East and Northeast China, Northeastern China (Inner Manchuria). The Amur proper is long, and has a drainage basin of . ''mizu'' ("water") in Japanese. The name "Amur" may have evolved from a root word for water, coupled with a size modifier for "Big Water". Its ancient Chinese names were ''Yushui'', ''Wanshui'' and ''Heishui'', formed from variants to ''shui'', meaning "water".The fishes of the Amur River:updated check-list and zoogeography'' The modern Chinese name for the river, ''Heilong Jiang'' means "Cardinal_directions#Cultural_variations, Black Dragon River", while the Manchurian language, Manchurian name ''Sahaliyan Ula'', the Mongolian names " Amar mörön " (Cyrillic: Амар мөрөн) originates from the name " Amar " meaning to rest and ''Khar mörön'' (Cyrillic: Хар ...
