Yama (river)
The Yama () is a river in Magadan Oblast, Russian Far East. It is long, with a drainage basin of . The R504 Kolyma Highway passes just west of the sources of the Yama. The name of the river is probably of Koryak origin. Course The Yama has its source in the southwestern slopes of the Maymandzhin Range, at the confluence of rivers Maimandzha and Maimachan, near Atka and not far from the sources of north-heading Maltan. It flows in a roughly southeastern direction along its entire course. The last stretch of the Yama is in a marshy coastal area where it divides into multiple sleeves and where there are many small thermokarst lakes on the right bank. Finally it flows by Yamsk village into the Perevolochny estuary, separated by a landspit from Yam Bay, at the southwest end of the Shelikhov Gulf, Sea of Okhotsk.Google EarthЯма |

Landspit
A spit (cognate with the word for a rotisserie bar) or sandspit is a deposition bar or beach landform off coasts or lake shores. It develops in places where re-entrance occurs, such as at a cove's headlands, by the process of longshore drift by longshore currents. The drift occurs due to waves meeting the beach at an oblique angle, moving sediment down the beach in a zigzag pattern. This is complemented by longshore currents, which further transport sediment through the water alongside the beach. These currents are caused by the same waves that cause the drift. Hydrology and geology Where the direction of the shore inland ''re-enters'', or changes direction, for example at a headland, the longshore current spreads out or dissipates. No longer able to carry the full load, much of the sediment is dropped. This is called deposition. This submerged bar of sediment allows longshore drift or littoral drift to continue to transport sediment in the direction the waves are breaking, ...

Dolly Varden Trout
The Dolly Varden trout (''Salvelinus malma'') is a species of salmonid ray-finned fish native to cold-water tributaries of the Pacific Ocean in Asia and North America. Despite the name "trout" (which typically refers to freshwater species from the genera ''Salmo'' and ''Oncorhynchus''), it belongs to the genus ''Salvelinus'' (chars), which includes 51 recognized species, the most prominent being the brook, lake and bull trout as well as the Arctic char. Although many populations are semi-anadromous, riverine and lacustrine populations occur throughout its range. It is considered by taxonomists as part of the ''Salvelinus alpinus'' (Arctic char) complex, as many populations of bull trout, Dolly Varden trout and Arctic char overlap. Taxonomy The scientific name of the Dolly Varden is ''Salvelinus malma''. The species was originally named by German naturalist and taxonomist Johann Julius Walbaum in 1792 based on type specimens from the Kamchatka Peninsula in Siberia. The name '' ...

Salvelinus Leucomaenis
''Salvelinus leucomaenis'', the whitespotted char, is an East Asian trout in the genus ''Salvelinus'', called ''iwana'' in Japanese and ''kundzha'' (кунджа) in Russian. Both landlocked and ocean-run forms occur. The landlocked form typically grows up to , and prefers low-temperature streams. The seagoing fish typically grows to long. The largest reported specimen was long and the oldest was nine years old. ''Iwana'' is widely fished in Japan. Apart from Hokkaido in Japan, the species is found in northeast Korea and in Russia in Sakhalin, Kuril Islands and Kamchatka. The kirikuchi char (''Salvelinus leucomaenis japonicus'' or ''Salvelinus japonicus'') is usually considered a subspecies In Taxonomy (biology), biological classification, subspecies (: subspecies) is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (Morphology (biology), morpholog ... of ''S. leucomaenis''.

Arctic Char
The Arctic char or Arctic charr (''Salvelinus alpinus'') is a cold-water fish in the family Salmonidae, native to alpine lakes, as well as Arctic and subarctic coastal waters in the Holarctic realm, Holarctic. Distribution and habitat It Spawn (biology), spawns in freshwater and its populations can be lacustrine, riverine, or anadromous, where they return from the ocean to their fresh water birth rivers to spawn. No other freshwater fish is found as far north; it is, for instance, the only fish species in Lake Hazen, which extends up to on Ellesmere Island in the Northern Canada, Canadian Arctic. It is one of the rarest fish species in Great Britain and Ireland, found mainly in deep, cold, glacial lakes, and is at risk there from acidification. In other parts of its range, such as the Nordic countries, it is much more common, and is fishery, fished extensively. In Siberia, it is known as ''golets'' () and it has been introduced in lakes where it sometimes threatens less hardy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coho Salmon
The coho salmon (''Oncorhynchus kisutch;'' Karuk: achvuun) is a species of anadromous fish in the salmon family (biology), family and one of the five Pacific salmon species. Coho salmon are also known as silver salmon (or "silvers") and is often sold as medium red salmon. The scientific species name is based on the Russian language, Russian common name ''kizhuch'' (кижуч). Description During their ocean phase, coho salmon have silver sides and dark-blue backs with spots on their back and upper tail lobe. During their spawning phase, their jaws and teeth become hooked. After entering fresh water, they develop bright-red sides, bluish-green heads and backs, dark bellies and dark spots on their backs. Sexually maturing fish develop a light-pink or rose shading along the belly, and the males may show a slight arching of the back. Mature adults have a pronounced red skin color with darker backs and spots, with females having darker shades than males. Coho salmon average 20 to ...

Pink Salmon
Pink salmon or humpback salmon (''Oncorhynchus gorbuscha'') is a species of euryhaline ray-finned fish in the family Salmonidae. It is the type species of the genus ''Oncorhynchus'' (Pacific salmon), and is the smallest and most abundant of the seven officially recognized species of salmon. The species' scientific name is based on the Russian common name for this species ''gorbúša'' (горбуша), which literally means ''humpie''. Description In the ocean, pink salmon are bright silver fish. After returning to their spawning streams, their coloring changes to pale grey on the back with yellowish-white belly (although some turn an overall dull green color). As with all salmon, in addition to the dorsal fin, they also have an adipose fin. The fish is characterized by a white mouth with black gums, no teeth on the tongue, large oval-shaped black spots on the back, a v-shaped tail, and an anal fin with 13–17 soft rays. During their spawning migration, males develop a pronou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ''tsəm'', meaning "spotted" or "marked"; while ''keta'' in the scientific name comes from Russian language, Russian, which in turn comes from the Evenki language of Eastern Siberia. The term 'Dog Salmon' is most commonly used in Alaska and refers to the Salmon whose flesh Alaskans use to feed their dogs. 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 "kype, hook-snout salmon" ( zh, 钩吻鲑), but is more often called the ''damaha'' fish (), which is loanw ...

Floodplain
A floodplain or flood plain or bottomlands is an area of land adjacent to a river. Floodplains stretch from the banks of a river channel to the base of the enclosing valley, and experience flooding during periods of high Discharge (hydrology), discharge.Goudie, A. S., 2004, ''Encyclopedia of Geomorphology'', vol. 1. Routledge, New York. The soils usually consist of clays, silts, sands, and gravels deposited during floods. Because of regular flooding, floodplains frequently have high soil fertility since nutrients are deposited with the flood waters. This can encourage farming; some important agricultural regions, such as the Nile and Mississippi Basin, Mississippi Drainage basin, river basins, heavily exploit floodplains. Agricultural and urban regions have developed near or on floodplains to take advantage of the rich soil and freshwater. However, the Flood risk, risk of inundation has led to increasing efforts to Flood control, control flooding. Formation Most floodplai ...

Great Soviet Encyclopedia
The ''Great Soviet Encyclopedia'' (GSE; , ''BSE'') is one of the largest Russian-language encyclopedias, published in the Soviet Union from 1926 to 1990. After 2002, the encyclopedia's data was partially included into the later ''Great Russian Encyclopedia'' in an updated and revised form. The GSE claimed to be "the first Marxist–Leninist general-purpose encyclopedia". Origins The idea of the ''Great Soviet Encyclopedia'' emerged in 1923 on the initiative of Otto Schmidt, a member of the Russian Academy of Sciences. In early 1924 Schmidt worked with a group which included Mikhail Pokrovsky, (rector of the Institute of Red Professors), Nikolai Meshcheryakov (Former head of the General Directorate for the Protection of State Secrets in the Press, Glavit, the State Administration of Publishing Affairs), Valery Bryusov (poet), Veniamin Kagan (mathematician) and Konstantin Kuzminsky to draw up a proposal which was agreed to in April 1924.
