The name comes from the Yakut language word Kheymchen, which is an area of open water surrounded by sea ice.W.J. Stringer and J.E. Groves. 1991''Extent of Polynyas in the Bering and Chukchi Seas''/ref> Course The river rises in the Upper Kolyma Highlands, eastern limits of the Chersky Range, at the confluence of Left Seymchan and Right Seymchan. It flows first in a northeast direction, bending along its course until it flows in a southeastern direction. Finally it meets the Kolyma near Seymchan, from its mouth, downstream from the mouth of the Buyunda on the opposite bank. Together with the Buyunda that flows roughly northwards on the other side of the Kolyma basin, the Seymchan forms the Seymchan-Buyunda Depression, which limits the Upper Kolyma Highlands from the east. Its main tributaries are the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Yakut Language
Yakut , also known as Yakutian, Sakha, Saqa or Saxa ( sah, саха тыла), is a Turkic language spoken by around 450,000 native speakers, primarily the ethnic Yakuts and one of the official languages of Sakha (Yakutia), a federal republic in the Russian Federation. The Yakut language differs from all other Turkic languages in the presence of a layer of vocabulary of unclear origin (possibly Paleo-Siberian). There is also a large number of words of Mongolian origin related to ancient borrowings, as well as numerous recent borrowings from Russian. Like other Turkic languages and their ancestor Proto-Turkic, Yakut is an agglutinative language and features vowel harmony. Classification Yakut is a member of the Northeastern Common Turkic family of languages, which also includes Shor, Tuvan and Dolgan. Like most Turkic languages, Yakut has vowel harmony, is agglutinative and has no grammatical gender. Word order is usually subject–object–verb. Yakut has been influenced b ...

Buyunda
The Buyunda (russian: Буюнда) is a river in Magadan Oblast, Russian Far East. It is a right tributary of the Kolyma, with a length of and a drainage basin of .Google Earth Together with the Seymchan that flows roughly southwards on the facing bank of the Kolyma basin, the Buyunda forms the Seymchan-Buyunda Depression, which limits the Upper Kolyma Highlands from the east. The name of the Buyunda originated in the Evenki language, meaning "where there are wild deer". Course The Buyunda is the seventh longest tributary of the Kolyma. It has its sources in the Kilgan Massif and heads roughly northwards across the mountainous area of the Maymandzhin Range. After entering the depression it meanders strongly across a wide and marshy floodplain, its main channel dividing into branches. Finally the river joins the right bank of the Kolyma from its mouth. Its confluence with the Kolyma is 100 km below the Ust-Srednekan Hydroelectric Station. Seymchan settlement and the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chersky Range
The Chersky Range (, ) is a chain of mountains in northeastern Siberia between the Yana River and the Indigirka River. Administratively the area of the range belongs to the Sakha Republic, although a small section in the east is within Magadan Oblast. The highest peak in the range is tall Peak Pobeda (Chersky Range), Peak Pobeda, part of the Ulakhan-Chistay Range. The range also includes important places of traditional Yakut culture, such as Ynnakh Mountain ''(Mat'-Gora)'' and kigilyakh rock formations. The Moma Natural Park is a protected area located in the southern zone of the range. History At some time between 1633 and 1642 Poznik Ivanov ascended a tributary of the lower Lena, crossed the Verkhoyansk Range to the upper Yana and then crossed the Chersky Range to the Indigirka. The range was sighted in 1926 by Sergei Obruchev (Vladimir Obruchev's son) and named by the Russian Geographical Society after the Polish explorer and geographer Ivan Chersky (or Jan Czerski).

Sea Ice
Sea ice arises as seawater freezes. Because ice is less dense than water, it floats on the ocean's surface (as does fresh water ice, which has an even lower density). Sea ice covers about 7% of the Earth's surface and about 12% of the world's oceans. Much of the world's sea ice is enclosed within the polar ice packs in the Earth's polar regions: the Arctic ice pack of the Arctic Ocean and the Antarctic ice pack of the Southern Ocean. Polar packs undergo a significant yearly cycling in surface extent, a natural process upon which depends the Arctic ecology, including the ocean's ecosystems. Due to the action of winds, currents and temperature fluctuations, sea ice is very dynamic, leading to a wide variety of ice types and features. Sea ice may be contrasted with icebergs, which are chunks of ice shelves or glaciers that calve into the ocean. Depending on location, sea ice expanses may also incorporate icebergs. General features and dynamics Sea ice does not simply grow and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drainage Basin
A drainage basin is an area of land where all flowing surface water converges to a single point, such as a river mouth, or flows into another body of water, such as a lake or ocean. A basin is separated from adjacent basins by a perimeter, the '' drainage divide'', made up of a succession of elevated features, such as ridges and hills. A basin may consist of smaller basins that merge at river confluences, forming a hierarchical pattern. Other terms for a drainage basin are catchment area, catchment basin, drainage area, river basin, water basin, and impluvium. In North America, they are commonly called a watershed, though in other English-speaking places, "watershed" is used only in its original sense, that of a drainage divide. In a closed drainage basin, or endorheic basin, the water converges to a single point inside the basin, known as a sink, which may be a permanent lake, a dry lake, or a point where surface water is lost underground. Drainage basins are similar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Upper Kolyma Highlands
The Upper Kolyma Highlands ( rus, Верхнеколымское нагорье) is a highland area in Magadan Oblast, Far Eastern Federal District, Russia. The biggest town in the highlands is Susuman. There are large deposits of gold, tin and rare metals in the Upper Kolyma Highlands. The area is relatively less desolate than other mountainous zones of Northeastern Siberia, such as the Yukaghir Highlands or the Nera Plateau. However, some of the mining operations were deemed unprofitable following the collapse of the USSR and certain settlements of the Susumansky District lost population. Only a residual population remains in Shiroky, Kholodny and Bolshevik. Other places such as Belichan and Kadykchan have become ghost towns. The R504 Kolyma Highway crosses the southern part of the highlands. Geography The Upper Kolyma Highlands are located in the upper course of the Kolyma. They are bound in the west by the Tas-Kystabyt and Suntar-Khayata ranges and to the east by the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tributary
A tributary, or affluent, is a stream or river that flows into a larger stream or main stem (or parent) river or a lake. A tributary does not flow directly into a sea or ocean. Tributaries and the main stem river drain the surrounding drainage basin of its surface water and groundwater, leading the water out into an ocean. The Irtysh is a chief tributary of the Ob river and is also the longest tributary river in the world with a length of . The Madeira River is the largest tributary river by volume in the world with an average discharge of . A confluence, where two or more bodies of water meet, usually refers to the joining of tributaries. The opposite to a tributary is a distributary, a river or stream that branches off from and flows away from the main stream. PhysicalGeography.net, Michael Pidwirny & S ...
