Continental Shelf Of Russia
The continental shelf of Russia (also called the Russian continental shelf or the Arctic shelf in the Arctic region) is a 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 coast. 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 ...

Continental Shelf
A continental shelf is a portion of a continent that is submerged under an area of relatively shallow water, known as a shelf sea. Much of these shelves were exposed by drops in sea level during glacial periods. The shelf surrounding an island is known as an ''insular shelf''. The continental margin, between the continental shelf and the abyssal plain, comprises a steep continental slope, surrounded by the flatter continental rise, in which sediment from the continent above cascades down the slope and accumulates as a pile of sediment at the base of the slope. Extending as far as 500 km (310 mi) from the slope, it consists of thick sediments deposited by turbidity currents from the shelf and slope. The continental rise's gradient is intermediate between the gradients of the slope and the shelf. Under the United Nations Convention on the Law of the Sea, the name continental shelf was given a legal definition as the stretch of the seabed adjacent to the shores of a par ...

Lomonosov Ridge
The Lomonosov Ridge (russian: Хребет Ломоносова, da, Lomonosovryggen) is an unusual underwater ridge of continental crust in the Arctic Ocean. It spans between the New Siberian Islands over the central part of the ocean to Ellesmere Island of the Canadian Arctic Archipelago.CBC NewsBroken ship halts Russian expedition to claim Arctic seabed 25 July 2007. Retrieved 25 July 2007. The ridge divides the Arctic Basin into the Eurasian Basin and the Amerasian Basin. The width of the Lomonosov Ridge varies from . It rises above the deep seabed. The minimum depth of the ocean above the ridge is less than .GEUS 2014, page 12 Slopes of the ridge are relatively steep, broken up by canyons, and covered with layers of silt. It is an aseismic ridge. The Lomonosov Ridge was first discovered by the Soviet high-latitude expeditions in 1948 and is named after Mikhail Lomonosov. The name was approved by the GEBCO Sub-Committee on Undersea Feature Names (SCUFN). Territorial ...

Ilyushin Il-18
The Ilyushin Il-18 (russian: Илью́шин Ил-18; NATO reporting name: Coot) is a large turboprop airliner that first flew in 1957 and became one of the best known and most durable Soviet aircraft of its era. The Il-18 was one of the world's principal airliners for several decades and was widely exported. Due to the aircraft's airframe durability, many examples achieved over 45,000 flight hours and the type remains operational in both military and (to a lesser extent) civilian capacities. The Il-18's successor was the long range Il-62 jet airliner. Design and development Two Soviet aircraft shared the designation Ilyushin Il-18. The first Il-18 was a propeller-driven airliner of 1946 but after a year of test flights that programme was abandoned. In the early 1950s with a need to replace older designs and increase the size of the Soviet civil transport fleet, a Soviet Council of Ministers directive was issued on 30 December 1955 to the chief designers Kuznetsov and Ivchenko ...

Helicopter
A helicopter is a type of rotorcraft in which lift and thrust are supplied by horizontally spinning rotors. This allows the helicopter to take off and land vertically, to 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 STOL (Short TakeOff and Landing) or STOVL (Short TakeOff and Vertical Landing) aircraft cannot perform without a runway. In 1942, the Sikorsky R-4 became the first helicopter to reach full-scale production.Munson 1968.Hirschberg, Michael J. and David K. Dailey"Sikorsky". ''US and Russian Helicopter Development in the 20th Century'', American Helicopter Society, International. 7 July 2000. Although most earlier designs used more than one main rotor, the configuration of a single main rotor accompanied by a vertical anti-torque tail rotor (i.e. unicopter, not to be confused with the single-blade monocopter) has become the most comm ...

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. , 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 since the Soviet times. Nuclear-powered icebreakers are much more powerful than their diesel-powered counterparts. Although nuclear propulsion is expensive to install and maintain, very heavy fuel demands, limitations on range, and difficulty refueling in the Arctic region can make diesel vessels less practical and less economical overall for these ice-breaking duties. During the winter, the ice along the Northern Sea Route varies in thickness from . The ice in central parts of the Arctic Ocean is on average thick. Nuclear-powered icebreakers can force through this ice at speeds up to . In ice-free waters, the maximum speed of the nuclear-powered icebreakers is as much as . Uses ...

Akademik Fedorov
RV ''Akademik Fedorov'' (russian: Академик Фёдоров) 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 manned drifting ice station North Pole-1. 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 scientists and researchers and two deep sea mini-submarines to the North Pole where the scientists were dispatched to a depth of more than where they dropped a titanium capsule containing a Russ ...

Siberia
Siberia ( ; rus, Сибирь, r=Sibir', p=sʲɪˈbʲirʲ, a=Ru-Сибирь.ogg) is an extensive geographical region, constituting all of North Asia, from the Ural Mountains in the west to the Pacific Ocean in the east. It has been a part of Russia since the latter half of the 16th century, after the Russians conquered lands east of the Ural Mountains. Siberia is vast and sparsely populated, covering an area of over , but home to merely one-fifth of Russia's population. Novosibirsk, Krasnoyarsk and Omsk are the largest cities in the region. Because Siberia is a geographic and historic region and not a political entity, there is no single precise definition of its territorial borders. Traditionally, Siberia extends eastwards from the Ural Mountains to the Pacific Ocean, and includes most of the drainage basin of the Arctic Ocean. The river Yenisey divides Siberia into two parts, Western and Eastern. Siberia stretches southwards from the Arctic Ocean to the hills of north-ce ...

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 the ...

Eurasia
Eurasia (, ) is the largest continental area on Earth, comprising all of Europe and Asia. Primarily in the Northern and Eastern Hemispheres, it spans from the British Isles and the Iberian Peninsula in the west to the Japanese archipelago and the Russian Far East to the east. The continental landmass is bordered by the Atlantic Ocean and Africa to the west, the Pacific Ocean to the east, the Arctic Ocean to the north, and by Africa, the Mediterranean Sea, and the Indian Ocean to the south. The division between Europe and Asia as two continents is a historical social construct, as many of their borders are over land; thus, in some parts of the world, Eurasia is recognized as the largest of the six, five, or four continents on Earth. In geology, Eurasia is often considered as a single rigid megablock. However, the rigidity of Eurasia is debated based on paleomagnetic data. Eurasia covers around , or around 36.2% of the Earth's total land area. It is also home to the largest ...

Crust (geology)
In geology, the crust is the outermost solid shell of a rocky 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 distinguished 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. Towa ...

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 locatio ...
