Yugorsky Peninsula
The Yugorsky Peninsula (russian: Югорский полуостров) is a large peninsula in Nenets Autonomous Okrug, Russia. It is limited by the Khaypudyr Bay in the Pechora Sea to the west and by the Baydaratsk Bay in the Kara Sea to the north and east. Compared to the Barents Sea, which receives relatively warm currents from the Atlantic Ocean, the Kara Sea is much colder, remaining frozen for over nine months a year. Thus often, in the spring and in the fall, the eastern coast of the Yugorsky Peninsula is frozen, while its western coast is clear of ice. The Yugorsky Strait and, beyond it, Vaygach Island lie at the northwestern end of this peninsula. The Pay-Khoy Ridge occupies the peninsula and extends from northwest to southeast. In the southeastern end of the Yugorsky Peninsula lies the Kara meteorite crater, while the Ust-Kara site lies offshore, 15 km east of the small Kara or Karskaya Guba inlet. It was formerly believed that these two sites were two separat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nenets Autonomous Okrug
The Nenets Autonomous Okrug (russian: Не́нецкий автоно́мный о́круг; Nenets languages, Nenets: Ненёцие автономной ӈокрук, ''Nenjocije awtonomnoj ŋokruk'') is a federal subjects of Russia, federal subject of Russia and an autonomous okrugs of Russia, autonomous okrug of Arkhangelsk Oblast. Its administrative center is the types of inhabited localities in Russia, town of Naryan-Mar. It has an area of and a population of 42,090 as of the Russian Census (2010), 2010 Census, making it the List of federal subjects of Russia by population, least populous federal subject. A plan to merge the autonomous okrug with Arkhangelsk Oblast was presented by the governors of both federal subjects on 13 May 2020, with a referendum planned for September, but was met with opposition by locals, leading to the merger process being scrapped completely.

Yugorsky Strait
The Yugorsky Strait or Yugor Strait (russian: Югорский Шар, or Yugorsky Shar) is a narrow sound between the Kara Sea and the Pechora Sea. Its maximum width is 10 km and its minimum width only 3 km. Ostrov Storozhevoy, an island 1.6 km in length, lies in the middle of the strait. This sound separates Vaygach Island from the Yugorsky Peninsula on the Russian mainland. The name is derived from Yugaria, an old name for the region to the south of Yugorsky Strait. History The earliest recorded voyage through the Yugorsky Shar, traditionally known as the Arctic "Iron Gateway", into the Kara Sea was made from Nizhny Novgorod by early Russian explorer Uleb in 1032. Russian "Pomors", the coastal dwellers of the White Sea shores, had been exploring this strait since the 11th century. The Arctic's first shipping line, the Great Mangazea Route, from the White Sea to the Ob River and the Yenisei Gulf began operating in the latter part of the 16th century. This li ...

Suevite
Suevite is a rock consisting partly of melted material, typically forming a breccia containing glass and crystal or lithic fragments, formed during an impact event. It forms part of a group of rock types and structures that are known as impactites. Name The word "suevite" is derived from "Suevia", Latin name of Swabia. It was suggested by Adolf Sauer in 1901. Formation Suevite is thought to form in and around impact craters by the sintering of molten fragments together with unmelted clasts of the country rock. Rocks formed from more completely melted material found in the crater floor are known as '' tagamites''. Suevite is distinct from the pseudotachylite in an impact structure as the latter is thought to have formed by frictional effects within the crater floor and below the crater during the initial compression phase of the impact and the subsequent formation of the central uplift. Occurrence Suevite is one of the diagnostic rock-types for large impact structures. It ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cretaceous
The Cretaceous ( ) is a geological period that lasted from about 145 to 66 million years ago (Mya). It is the third and final period of the Mesozoic Era, as well as the longest. At around 79 million years, it is the longest geological period of the entire Phanerozoic. The name is derived from the Latin ''creta'', "chalk", which is abundant in the latter half of the period. It is usually abbreviated K, for its German translation ''Kreide''. The Cretaceous was a period with a relatively warm climate, resulting in high eustatic sea levels that created numerous shallow inland seas. These oceans and seas were populated with now- extinct marine reptiles, ammonites, and rudists, while dinosaurs continued to dominate on land. The world was ice free, and forests extended to the poles. During this time, new groups of mammals and birds appeared. During the Early Cretaceous, flowering plants appeared and began to rapidly diversify, becoming the dominant group of plants across the Earth b ...

Kara Crater
Kara is a meteorite crater in the Yugorsky Peninsula, Nenetsia, Russia. Heavily eroded, it is presently in diameter, though it is thought to be originally before erosion. Its age is estimated to be 70.3 ± 2.2 million years old (Late Cretaceous). Impactite outcrops located on the Baydarata Gulf (Baydaratskaya) shore north-east of the crater imply that the original size of the crater could have been the 4th largest on Earth. The crater is not exposed at the surface. The Kara crater lies in the southeastern end of the Yugorsky Peninsula, while the Ust-Kara site lies offshore, east of the small Kara or Karskaya Guba inlet. It was formerly believed that these two sites were two separate craters and that they formed a twin impact structure from the Late Cretaceous. However, it seems that the Ust-Kara site does not exist as a separate site. Apparently, the suevite Suevite is a rock consisting partly of melted material, typically forming a breccia containing glass and crysta ...

Pay-Khoy
The Pay-Khoy Range ( rus, хребет Пай-Хой) is a mountain range at the northern end of the Ural Mountains. It lies within the Nenets Autonomous Okrug. Geography The ridge is extended from northwest to southeast. It is located on the Yugorsky Peninsula, in the eastern part of the Nenets Autonomous Okrug. The ridge continues to Vaygach Island, thus separating the Barents Sea and the Kara Sea. The highest point of Pay-Khoy is the mountain of Moreiz (). The range separates the drainage basins of the (west, Barents Sea) and the Kara River (east, Kara Sea). The areas around Pay-Khoy do not have permanent population. The closest permanent settlements are Amderma and Ust-Kara, Nenets Autonomous Okrug The range is located in the tundra, to the north of the tree line. Geology The Pay-Khoy range forms a curved orogen together with the Ural Mountains, Vaygach Island and the Novaya Zemlya Novaya Zemlya (, also , ; rus, Но́вая Земля́, p=ˈnovəjə zʲɪmˈlʲa, ) ...

Atlantic Ocean
The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about . It covers approximately 20% of Earth's surface and about 29% of its water surface area. It is known to separate the " Old World" of Africa, Europe and Asia from the "New World" of the Americas in the European perception of the World. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and North and South America to the west. As one component of the interconnected World Ocean, it is connected in the north to the Arctic Ocean, to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south (other definitions describe the Atlantic as extending southward to Antarctica). The Atlantic Ocean is divided in two parts, by the Equatorial Counter Current, with the North(ern) Atlantic Ocean and the South(ern) Atlantic Ocean split at about 8°N.
