Aleksandr Kuznetsov (explorer)
Aleksandr Kuznetsov was the expedition leader of the first undisputed team to set foot on the North Pole. Other claimants, notably Frederick Cook (1908) and Robert Peary Robert Edwin Peary Sr. (; May 6, 1856 – February 20, 1920) was an American explorer and officer in the United States Navy who made several expeditions to the Arctic in the late 19th and early 20th centuries. He is best known for, in Apri ... (1909) have been criticized for a lack of supporting logs, having no one to confirm sextant readings or other reasons. Kuznetsov led the Sever-2 team of Soviet scientists who flew and landed three Lisunov Li-2s at the North Pole on April 23, 1948. Soundings made by the team were the first to indicate an underwater mountain ridge beneath the ice and water at the North Pole.

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 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 some perhaps semi-per ...

Frederick Cook
Frederick Albert Cook (June 10, 1865 – August 5, 1940) was an American explorer, physician, and ethnographer who claimed to have reached the North Pole on April 21, 1908. That was nearly a year before Robert Peary, who similarly claimed to have reached the North Pole on April 6, 1909. Both men's accounts have been disputed ever since. His expedition was the first, and the only one with a United States national, to find a previously unknown, to people of European descent, North American Arctic island, Meighen Island. In December 1909, after reviewing Cook's limited records, a commission of the University of Copenhagen ruled his claim unproven. In 1911, Cook published a memoir of his expedition that continued his claim. His account of reaching the summit of Denali (Mount McKinley) in Alaska has also been discredited. Biography Cook was born in Hortonville, New York, in Sullivan County. (His birthplace is sometimes listed as Callicoon or Delaware, both also in Sul ...

Robert Peary
Robert Edwin Peary Sr. (; May 6, 1856 – February 20, 1920) was an American explorer and officer in the United States Navy who made several expeditions to the Arctic in the late 19th and early 20th centuries. He is best known for, in April 1909, leading an expedition that claimed to be the first to have reached the geographic North Pole. Explorer Matthew Henson, part of the expedition, is thought to have reached what they believed to be the North Pole narrowly before Peary. Peary was born in Cresson, Pennsylvania, but, following his father's death at a young age, was raised in Portland, Maine. He attended Bowdoin College, then joined the United States Coast and Geodetic Survey as a draftsman. He enlisted in the navy in 1881 as a civil engineer. In 1885, he was made chief of surveying for the Nicaragua Canal, which was never built. He visited the Arctic for the first time in 1886, making an unsuccessful attempt to cross Greenland by dogsled. In the Peary expedition to G ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soviet Union
The Soviet Union,. officially the Union of Soviet Socialist Republics. (USSR),. was a List of former transcontinental countries#Since 1700, transcontinental country that spanned much of Eurasia from 1922 to 1991.

Lisunov Li-2
The Lisunov Li-2 (NATO reporting name: Cab), originally designated PS-84, was a license-built Soviet-version of the Douglas DC-3. It was produced by Factory #84 in Moscow-Khimki and, after evacuation in 1941, at TAPO in Tashkent. The project was directed by aeronautical engineer Boris Pavlovich Lisunov. Design and development The Soviet Union received its first DC-2 in 1935. A total of 18 DC-3s had been ordered on 11 April 1936, and the government of the USSR purchased 21 DC-3s for operation by Aeroflot before World War II. A production license was awarded to the government of the USSR on 15 July 1936. Lisunov spent two years at the Douglas Aircraft Company, between November 1936 and April 1939 translating the design. One of the engineers who accompanied him to Douglas was Vladimir Mikhailovich Myasishchev. Design work and production were undertaken at State Aviation Factory 84 in Khimki (now a suburb of Moscow).

Depth Sounding
Depth sounding, often simply called sounding, is measuring the depth of a body of water. Data taken from soundings are used in bathymetry to make maps of the floor of a body of water, such as the seabed topography. Soundings were traditionally shown on nautical charts in fathoms and feet. The National Oceanic and Atmospheric Administration (NOAA), the agency responsible for bathymetric data in the United States, still uses fathoms and feet on nautical charts. In other countries, the International System of Units (metres) has become the standard for measuring depth. Terminology "Sounding" derives from the Old English ''sund'', meaning "swimming, water, sea"; it is not related to the word ''sound'' in the sense of noise or tones, but to ''sound'', a geographical term. Traditional terms for soundings are a source for common expressions in the English language, notably "deep six" (a sounding of 6 fathoms). On the Mississippi River in the 1850s, the leadsmen also used old-fash ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Russian Explorers
The history of exploration by citizens or subjects of the Russian Federation, the Soviet Union, the Russian Empire, the Tsardom of Russia and other Russian predecessor states forms a significant part of the history of Russia as well as the history of the world. At , Russia is the largest country in the world, covering more than a ninth of Earth's landmass. In the times of the Soviet Union and the Russian Empire, the country's share in the world's landmass reached 1/6. Most of these territories were first discovered by Russian explorers (if indigenous peoples of inhabited territories are not counted). Contiguous exploration in Eurasia and the building of overseas colonies in Russian America were some of the primary factors in Russian territorial expansion. Apart from their discoveries in Alaska, Central Asia, Siberia, and the northern areas surrounding the North Pole, Russian explorers have made significant contributions to the exploration of the Antarctic, Arctic, ...
