Georgiy Sedov
Georgy Yakovlevich Sedov (russian: Гео́ргий Я́ковлевич Седо́в; – ) was a Russian Arctic explorer. Born in the village of Krivaya Kosa of Taganrog district (now Novoazovskyi Raion, Donetsk Oblast) in a fisherman's family. In 1898, Sedov finished navigation courses in Rostov-on-Don and acquired the rank of long voyage navigator. In 1901, he took an external degree at Naval College, passed all the exams and was promoted to the rank of lieutenant. In 1902–1903, Sedov participated in a hydrographic expedition in the Arctic Ocean. During the Russo-Japanese War he was in charge of a torpedo boat (1905). In 1909, he led the expedition that would later describe the mouth of the Kolyma river. A year later Sedov explored the Krestovaya Bay on Novaya Zemlya. In 1912, he suggested a sleigh expedition for reaching the North Pole. The Tsarist government refused to finance this project, and the expedition was organized with the help from independent sources. ...

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 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 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-permanent gravel banks lie slightly clos ...

Glacier
A glacier (; ) is a persistent body of dense ice that is constantly moving under its own weight. A glacier forms where the accumulation of snow exceeds its Ablation#Glaciology, ablation over many years, often Century, centuries. It acquires distinguishing features, such as Crevasse, crevasses and Serac, seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water. On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on every continent other than the Australian mainland, including Oceania's high-latitude oceanic island countries such as New Zealand.

Mountain
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited Summit (topography), summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are Monadnock, isolated summits, but most occur in mountain ranges. Mountain formation, Mountains are formed through Tectonic plate, tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through Slump (geology), slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce Alpine climate, colder climates than at sea level at similar latitude. These colder climates strongly affect the Montane ecosystems, ecosys ...

Headlands And Bays
A headland, also known as a head, is a coastal landform, a point of land usually high and often with a sheer drop, that extends into a body of water. It is a type of promontory. A headland of considerable size often is called a cape.Whittow, John (1984). ''Dictionary of Physical Geography''. London: Penguin, 1984, pp. 80, 246. . Headlands are characterised by high, breaking waves, rocky shores, intense erosion, and steep sea cliff. Headlands and bays are often found on the same coastline. A bay is flanked by land on three sides, whereas a headland is flanked by water on three sides. Headlands and bays form on discordant coastlines, where bands of rock of alternating resistance run perpendicular to the coast. Bays form when weak (less resistant) rocks (such as sands and clays) are eroded, leaving bands of stronger (more resistant) rocks (such as chalk, limestone, and granite) forming a headland, or peninsula. Through the deposition of sediment within the bay and the erosion of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jan Nagórski
Alfons Jan Nagórski (1888–1976), also known as ''Ivan Iosifovich Nagurski'', was a Polish engineer and pioneer of aviation, the first person to fly an airplane in the Arctic and the first aviator to perform a loop with a flying boat. Biography Early life Jan Nagórski was born on January 27, 1888, in Włocławek, Russian Empire. He completed a local trade school and in 1909 graduated from an infantry junker school in Odessa and the All-Russian Aeroclub in 1912. The following year he accomplished his training at the Naval Engineering School in Gatchina near St. Petersburg where he earned his wings. He was among the first pilots of the Imperial Russian Navy. Career In 1914 Nagórski was tasked with the difficult mission of locating the expedition of Georgy Sedov, Georgy Brusilov, and Vladimir Rusanov in the Russian Arctic. In a Maurice Farman MF11 plane, specially purchased for that purpose in France, Nagórski embarked on a ship in Arkhangelsk and arrived to Novaya Zemly ...

Valerian Albanov
Valerian Ivanovich Albanov (russian: Валериа́н Ива́нович Альбанов; 26 May 1881 – 1919) was a Russian navigator, best known for being one of two survivors of the Brusilov expedition of 1912, which killed 22. Early life Albanov was born in 1881 in Voronezh and was raised by his uncle in the city of Ufa. At the age of seventeen he entered the Naval College at Saint Petersburg, from which he graduated in 1904. Brusilov expedition He served on board a number of ships before signing on as navigator aboard the , under Captain Georgy Brusilov, for an intended expedition to traverse the Northern Sea Route – a feat which only once before had been successfully completed, by explorer Adolf Erik Nordenskiöld. The expedition was ill-planned and ill-executed by Brusilov, and the ''Svyataya Anna'' became locked in the sea ice of the Kara Sea in October 1912. Supplies were abundant, so officers and crew prepared themselves for wintering, hopi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rudolf Island
Prince Rudolf Land, Crown Prince Rudolf Land, Prince Rudolf Island or Rudolf Island (russian: Остров Рудольфа) is the northernmost island of the Franz Josef Archipelago, Russia and is home to the northernmost point in Russia. Owing to the island's location, its sheltered Teplitz Bay has served as a staging area for numerous polar expeditions. History The island was named by the Austro-Hungarian North Pole Expedition in honor of Archduke Rudolf (1858–1889), Crown Prince of Austria, Hungary and Bohemia. It belongs to the Arkhangelsk Oblast administrative region of the Russian Federation. During the second International Polar Year, a weather station established on the island was the northernmost scientific outpost in the world.Althoff, William F. ''Drift Station: Arctic Outposts of Superpower Science''. Potomac Books Inc., Dulles, Virginia. 2007. p. 38 Sheltered Teplitz Bay has been used as a stopping point for northbound ships. During 1899–1900, an expedition led ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scurvy
Scurvy is a disease resulting from a lack of vitamin C (ascorbic acid). Early symptoms of deficiency include weakness, feeling tired and sore arms and legs. Without treatment, decreased red blood cells, gum disease, changes to hair, and bleeding from the skin may occur. As scurvy worsens there can be poor wound healing, personality changes, and finally death from infection or bleeding. It takes at least a month of little to no vitamin C in the diet before symptoms occur. In modern times, scurvy occurs most commonly in people with mental disorders, unusual eating habits, alcoholism, and older people who live alone. Other risk factors include intestinal malabsorption and dialysis. While many animals produce their own vitamin C, humans and a few others do not. Vitamin C is required to make the building blocks for collagen. Diagnosis is typically based on physical signs, X-rays, and improvement after treatment. Treatment is with vitamin C supplements taken by mouth. Improvemen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hooker Island
Hooker Island (russian: остров Гукера; ''Ostrov Gukera'') is one of the central islands of Franz Josef Land. It is located in the central area of the archipelago at . It is administered by the Arkhangelsk Oblast, Russia. History Hooker Island was discovered by the 1880 expedition to Franz Josef Land led by Benjamin Leigh Smith. It was named after British naturalist Sir Joseph Dalton Hooker who went with James Clark Ross' expedition on ships ''Erebus'' and ''Terror'' to Antarctica in 1839. Remains of a plesiosaur ''(Peloneustes philarchus)'' have been found in Hooker Island. Caribou antlers have been found as well, suggesting that herds reached here up to about 1,300 years ago during a period where the earth had a warmer climate. Tikhaya Bay was the site of a major base for polar expeditions, and the location of a meteorological station from 1929 to 1963. There is another bay in the south of the island called Zaliv Makarova and another in the east known as Ledn. El ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
