Chekanovsky Ridge
The Chekanovsky Ridge (russian: Кряж Чекановского; sah, Чекановскай томтороот) is a range of mountains in the Bulunsky District, Yakutia, Russian Federation. The area of the range is uninhabited. The range was named after explorer of Siberia Alexander Chekanovsky (1833–1876). History Rising in a remote and unexplored area, the range was formerly unknown. In 1875, during his third Siberian expedition, Alexander Chekanovsky intended to "go along the banks of the Lena to the mouth and, if possible, then go to the mouth of the Olenyok (river), Olenyok from the Laptev Sea." He hoped to have time to conduct geological exploration of the banks of the Lena River before the onset of winter, but a short summer frustrated his plans. From a barge Chekanovsky navigated the Lena River for a distance of about from Yakutsk to the mouth to the Eyekit river, its last major left tributary. He explored inland from the deep and wide lower course of the Eyekit, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Envisat
Envisat ("Environmental Satellite") is a large inactive Earth-observing satellite which is still in orbit and now considered space debris. Operated by the European Space Agency (ESA), it was the world's largest civilian Earth observation satellite. It was launched on 1 March 2002 aboard an Ariane 5 from the Guyana Space Centre in Kourou, French Guiana, into a Sun synchronous polar orbit at an altitude of 790 ± 10 km. It orbits the Earth in about 101 minutes, with a repeat cycle of 35 days. After losing contact with the satellite on 8 April 2012, ESA formally announced the end of Envisat's mission on 9 May 2012. Envisat cost 2.3 billion Euro (including 300 million Euro for 5 years of operations) to develop and launch. The mission has been replaced by the Sentinel series of satellites. The first of these, Sentinel 1, has taken over the radar duties of Envisat since its launch in 2014. Mission Envisat was launched as an Earth observation satellite. Its objective ...

It is a tributary of the Olenyok (river), Olenyok with a length of and a drainage basin area of . The river flows north of the Arctic Circle across a desolate area of Bulunsky District devoid of settlements. The nearest inhabited places are Taymylyr, located downstream from its confluence with the Olenyok, and Sklad (Tyumyati), located a little upstream. History In 1875, during his third Siberian expedition, Alexander Chekanovsky intended to "go along the banks of the Lena to the mouth and, if possible, then go to the mouth of the Olenyok (river), Olenyok from the Laptev Sea." From a barge Chekanovsky navigated the Lena River for a distance of about from Yakutsk to the mouth to the Eyekit river, its last major left tributary. He explored inland from the deep and wide lower course of the Eyekit, and then along the rocky and mountainous watershed area ly ...

Great Soviet Encyclopedia
The ''Great Soviet Encyclopedia'' (GSE; ) 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 ''Bolshaya rossiyskaya entsiklopediya'' (or '' 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 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. Also involved was Anatoly Lunacharsky, People's Commissar of Education ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tundra
In physical geography, tundra () is a type of biome where tree growth is hindered by frigid temperatures and short growing seasons. The term ''tundra'' comes through Russian (') from the Kildin Sámi word (') meaning "uplands", "treeless mountain tract". There are three regions and associated types of tundra: Arctic tundra, alpine tundra, and Antarctic tundra. Tundra vegetation is composed of dwarf shrubs, sedges, grasses, mosses, and lichens. Scattered trees grow in some tundra regions. The ecotone (or ecological boundary region) between the tundra and the forest is known as the tree line or timberline. The tundra soil is rich in nitrogen and phosphorus. The soil also contains large amounts of biomass and decomposed biomass that has been stored as methane and carbon dioxide in the permafrost, making the tundra soil a carbon sink. As global warming heats the ecosystem and causes soil thawing, the permafrost carbon cycle accelerates and releases much of these soil-contained g ...

Laptev Sea
The Laptev Sea ( rus, мо́ре Ла́птевых, r=more Laptevykh; sah, Лаптевтар байҕаллара, translit=Laptevtar baỹğallara) is a marginal sea of the Arctic Ocean. It is located between the northern coast of Siberia, the Taimyr Peninsula, Severnaya Zemlya and the New Siberian Islands. Its northern boundary passes from the Arctic Cape to a point with co-ordinates of 79°N and 139°E, and ends at the Anisiy Cape. The Kara Sea lies to the west, the East Siberian Sea to the east. The sea is named after the Russian explorers Dmitry Laptev and Khariton Laptev; formerly, it had been known under various names, the last being Nordenskiöld Sea (russian: link=no, мо́ре Норденшёльда), after explorer Adolf Erik Nordenskiöld. The sea has a severe climate with temperatures below 0 °C (32 °F) over more than nine months per year, low water salinity, scarcity of flora, fauna and human population, and low depths (mostly less than 50 meters) ...

Lena (river)
The Lena (russian: Ле́на, ; evn, Елюенэ, ''Eljune''; sah, Өлүөнэ, ''Ölüöne''; bua, Зүлхэ, ''Zülkhe''; mn, Зүлгэ, ''Zülge'') is the easternmost of the three great Siberian rivers that flow into the Arctic Ocean (the other two being the Ob and the Yenisey). Permafrost underlies most of the catchment, 77% of which is continuous. It is long, and has a drainage basin of . The Lena is the eleventh-longest river in the world, and the longest river entirely within Russia. Course Originating at an elevation of at its source in the Baikal Mountains south of the Central Siberian Plateau, west of Lake Baikal, the Lena flows northeast across the Lena-Angara Plateau, being joined by the Kirenga, Vitim and Olyokma. From Yakutsk it enters the Central Yakutian Lowland and flows north until joined by its right-hand tributary the Aldan and its most important left-hand tributary, the Vilyuy. After that, it bends westward and northward, flowing between the K ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arctic Circle
The Arctic Circle is one of the two polar circles, and the most northerly of the five major circles of latitude as shown on maps of Earth. Its southern equivalent is the Antarctic Circle. The Arctic Circle marks the southernmost latitude at which, on the December solstice, the shortest day of the year in the northern hemisphere, the sun will not rise all day, and on the June solstice, the longest day of the year in the northern hemisphere, the sun will not set. These phenomena are referred to as polar night and midnight sun respectively, and the further north one progresses, the more pronounced these effects become. For example, in the Russian port city of Murmansk, three degrees above the Arctic Circle, the sun does not rise for 40 successive days in midwinter. The position of the Arctic Circle is not fixed and currently runs north of the Equator. Its latitude depends on the Earth's axial tilt, which fluctuates within a margin of more than 2° over a 41,000-year period, o ...
