Continental Shelf Of Russia
The continental shelf of Russia or the Russian continental shelf is the continental shelf adjacent to the Russian Federation. Geologically, the extent of the shelf is defined as the entirety of the continental shelves adjacent to Russia's coasts. In international law, however, the United Nations Convention on the Law of the Sea more narrowly defines the extent of the shelf as the seabed and subsoil of the submarine areas over which a state exercises sovereign rights. The Siberian Shelf in the Arctic Ocean is the largest (and least explored) of the Russian shelves, a region of strategic importance because of its oil and natural gas reserves. Other parts of the Russian shelf are typically named after the corresponding seas: Barents Shelf ( Barents Sea Shelf), Chukchi Shelf ( Chukchi Sea Shelf), etc. With the exception of internal Russian seas, these geological shelves are shared with other countries which share the corresponding seas. For example, the Chukchi Shelf is shared bet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North Pole
The North Pole, also known as the Geographic North Pole or Terrestrial North Pole, is the point in the Northern Hemisphere where the Earth's rotation, Earth's axis of rotation meets its surface. It is called the True North Pole to distinguish from the North magnetic pole, Magnetic North Pole. The North Pole is by definition the northernmost point on the Earth, lying antipode (geography), antipodally to the South Pole. It defines geodetic latitude 90° North, as well as the direction of true north. At the North Pole all directions point south; all lines of longitude converge there, so its longitude can be defined as any degree value. No time zone has been assigned to the North Pole, so any time can be used as the local time. Along tight latitude circles, counterclockwise is east and clockwise is west. The North Pole is at the center of the Northern Hemisphere. The nearest land is usually said to be Kaffeklubben Island, off the northern coast of Greenland about away, though ...

Helicopter
A helicopter is a type of rotorcraft in which Lift (force), lift and thrust are supplied by horizontally spinning Helicopter rotor, rotors. This allows the helicopter to VTOL, take off and land vertically, to hover (helicopter), hover, and to fly forward, backward and laterally. These attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft and many forms of short take-off and landing (STOL) or short take-off and vertical landing (STOVL) aircraft cannot perform without a runway. The Focke-Wulf Fw 61 was the first successful, practical, and fully controllable helicopter in 1936, while in 1942, the Sikorsky R-4 became the first helicopter to reach full-scale mass production, production. Starting in 1939 and through 1943, Igor Sikorsky worked on the development of the Vought-Sikorsky VS-300, VS-300, which over four iterations, became the basis for modern helicopters with a single main rotor and a single tail rotor.

Nuclear Powered Icebreaker
A nuclear-powered icebreaker is an icebreaker with an onboard nuclear power plant that produces power for the vessel's propulsion system. Although more expensive to operate, nuclear-powered icebreakers provide a number of advantages over their diesel-powered counterparts, especially along the Northern Sea Route where diesel-powered icebreaker operations are challenging due to the heavy power demand associated with icebreaking, limited refueling infrastructure along the Siberian coast, and the endurance required. , Russia is the only country that builds and operates nuclear-powered icebreakers, having built a number of such vessels to aid shipping along the Northern Sea Route and Russian arctic outposts since the Soviet era. History of nuclear-powered icebreakers The first nuclear icebreaker was the Soviet vessel ''Lenin'', which was launched in 1957 as the world’s first nuclear-powered surface vessel and the first civilian-operated nuclear vessel. An experimental nuclear-pow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rossiya (1983 Icebreaker)
''Rossiya'' (; literally: Russia) is a Russian ''Arktika''-class nuclear-powered icebreaker. In 1990, it became the first ship to carry commercial passenger traffic to the geographic North Pole. Its sister ship ''Arktika'' was the first surface ship to reach the pole. During the winter of 2012–2013, ''Rossiya'' was stationed in the Gulf of Finland The Gulf of Finland (; ; ; ) is the easternmost arm of the Baltic Sea. It extends between Finland to the north and Estonia to the south, to Saint Petersburg—the second largest city of Russia—to the east, where the river Neva drains into it. ....

Akademik Fedorov
RV ''Akademik Fedorov'' () is a Russian scientific diesel-electric research vessel, the flagship of the Russian polar research fleet. It was built in Rauma, Finland for the Soviet Union and completed on 8 September 1987. It started operations on 24 October 1987, in the USSR. The ship was named after a Soviet polar explorer, academician of the USSR Academy of Sciences Evgeny Fyodorov, who worked on the first Soviet crewed drifting ice station North Pole-1. Research vessel ''Akademik Fedorov'' participated in MOSAiC Expedition in 2019-2020 supporting and resupplying the main research icebreaker Polarstern, and also held a six-week course for 20 students for MOSAiC School 2019. 2007 Russian North Pole expedition ''Akademik Fedorov'' made news on 1 August 2007, when it sailed in the path of an icebreaker on the way to the North Pole as part of Russia's efforts to lay claim to the sea bed beneath the North Pole. On 2 August 2007, ''Akademik Fedorov'' sailed with 100 scientist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Alpha Ridge
The Alpha Ridge is a major volcanic ridge under the Arctic Ocean between the Canada Basin (off Ellesmere Island) and the Lomonosov Ridge. It was active during the formation of the Amerasian Basin. It was discovered in 1963. The highest elevation is about 2,700 m over the ocean floor. It is 200 to 450 km wide. The Alpha Ridge, Lomonosov Ridge, and Nansen-Gakkel Ridge are the three major ranges that divide the Arctic Ocean floor, running generally parallel to each other. The 1983 Canadian Expedition to Study the Alpha Ridge (CESAR) seemed to establish that the Alpha Ridge is an extension of the continent from Ellesmere Island and hence there is a possibility that Canada may lay claim to the resource rights for the region, in particular for petroleum, according to the United Nations' Law of the Sea. There is no final conclusion to the issue so far, and part of the research planned for the European Drilling Research Icebreaker (''Aurora Borealis'') was drilling of t ...

Eurasia
Eurasia ( , ) is a continental area on Earth, comprising all of Europe and Asia. According to some geographers, Physical geography, physiographically, Eurasia is a single supercontinent. The concept of Europe and Asia as distinct continents dates back to classical antiquity, antiquity, but their borders have historically been subject to change. For example, the ancient Greeks originally included Africa in Asia but classified Europe as separate land. Eurasia is connected to Africa at the Suez Canal, and the two are sometimes combined to describe the largest contiguous landmass on Earth, Afro-Eurasia. History Eurasia has been the host of many ancient civilizations, including those based in Mesopotamia, Egypt, the Indus Valley and China. In the Axial Age (mid-first millennium BCE), a continuous belt of civilizations stretched through the Eurasian Subtropics, subtropical zone from the Atlantic to the Pacific. This belt became the mainstream of world history for two millennia. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crust (geology)
In geology, the crust is the outermost solid shell of a planet, dwarf planet, or natural satellite. It is usually distinguished from the underlying mantle by its chemical makeup; however, in the case of icy satellites, it may be defined based on its phase (solid crust vs. liquid mantle). The crusts of Earth, Mercury, Venus, Mars, Io, the Moon and other planetary bodies formed via igneous processes and were later modified by erosion, impact cratering, volcanism, and sedimentation. Most terrestrial planets have fairly uniform crusts. Earth, however, has two distinct types: continental crust and oceanic crust. These two types have different chemical compositions and physical properties and were formed by different geological processes. Types of crust Planetary geologists divide crust into three categories based on how and when it formed. Primary crust / primordial crust This is a planet's "original" crust. It forms from solidification of a magma ocean. Toward the end o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Polar Year
The International Polar Years (IPY) are collaborative, international efforts with intensive research focus on the polar regions. Karl Weyprecht, an Austro-Hungarian naval officer, motivated the endeavor in 1875, but died before it first occurred in 1882–1883. Fifty years later (1932–1933) a second IPY took place. The International Geophysical Year was inspired by the IPY and was organized 75 years after the first IPY (1957–58). The fourth, and most recent, IPY covered two full annual cycles from March 2007 to March 2009. The First International Polar Year (1882–1883) The First International Polar Year was proposed by an Austro-Hungarian naval officer, Karl Weyprecht, in 1875 and organized by Georg Neumayer, director of the German Maritime Observatory. Rather than settling for traditional individual and national efforts, they pushed for a coordinated scientific approach to researching Arctic phenomena. Observers made coordinated geophysical measurements at multiple loca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
