Koolen (surname)
Koolen ( esx, Koglu, label= Eskimo–Aleut) is a lake of Chukotsky District, Chukotka Autonomous Okrug, Russia. Its name originated in the Chukchi word ''Koolёn'', a fault or deep chasm. Geography Koolen is a long and narrow lake located in the Inan Range area of the Chukotka Mountains, at the eastern end of the Chukotka Peninsula, 13 km from the coast of the Chukchi Sea. The highest point near the lake is Mount Yttyvyt, a mountain. Koolen has a tectonic origin. Its water has a very weak content in minerals and is very transparent. The lake has a deep-blue tint and in the areas of greater depths the blue is so dark that it looks almost black. The area around the lake is uninhabited, the nearest town is Lavrentiya, located 44 km to the southwest. Fauna Arctic char, least cisco and grayling are common in the waters of the lake.

Sentinel-2
Sentinel-2 is an Earth observation mission from the Copernicus Programme that systematically acquires optical imagery at high spatial resolution (10 m to 60 m) over land and coastal waters. The mission is currently a constellation with two satellites, Sentinel-2A and Sentinel-2B; a third satellite, Sentinel-2C, is currently undergoing testing in preparation for launch in 2024. The mission supports a broad range of services and applications such as agricultural monitoring, emergencies management, land cover classification or water quality. Sentinel-2 has been developed and is being operated by the European Space Agency, and the satellites were manufactured by a consortium led by Airbus Defence and Space in Friedrichshafen. Overview The Sentinel-2 mission has the following key characteristics: * Multi-spectral data with 13 bands in the visible, near infrared, and short wave infrared part of the spectrum * Systematic global coverage of land surfaces from 56° S to 84°&nb ...

Tectonic
Tectonics (; ) are the processes that control the structure and properties of the Earth's crust and its evolution through time. These include the processes of mountain building, the growth and behavior of the strong, old cores of continents known as cratons, and the ways in which the relatively rigid plates that constitute the Earth's outer shell interact with each other. Tectonics also provide a framework for understanding the earthquake and volcanic belts that directly affect much of the global population. Tectonic studies are important as guides for economic geologists searching for fossil fuels and ore deposits of metallic and nonmetallic resources. An understanding of tectonic principles is essential to geomorphologists to explain erosion patterns and other Earth surface features. Main types of tectonic regime Extensional tectonics Extensional tectonics is associated with the stretching and thinning of the crust or the lithosphere. This type of tectonics is found ...

Thymallus
''Thymallus'' is a genus of freshwater fish in the salmon family Salmonidae; it is the only genus of subfamily Thymallinae. The type species is ''Thymallus thymallus,'' the grayling. The species in the genus are generically called graylings, but without qualification this also refers specifically to ''T. thymallus.'' Distribution The fishes of this genus are native to the northern parts of the Palearctic and Nearctic realms, ranging from the United Kingdom and northern Europe across Eurasia to Siberia, as well as northern North America. ''T. thymallus'', the grayling, is widespread in Europe, and ''T. arcticus,'' the Arctic grayling, is widespread throughout Eurasia east of the Ural Mountains and in the Nearctic. The other species have more localized ranges in northern Asia. Appearance ''Thymallus'' species are distinguished from other members of the salmon family by their larger scales, their small mouths with teeth on the maxillary bone, and most striking of all, their showy, ...

Least Cisco
''Coregonus sardinella'', known as the least cisco or the sardine cisco, is a fresh- and brackishwater salmonid fish that inhabits rivers, estuaries and coastal waters of the marginal seas of the Arctic Basin, as well as some large lakes of those areas. In North America it is found from the Murchison River (Nunavut) west through the Bering Strait to the Bristol Bay (Bering Sea) in Alaska, and in the Russian Arctic from the northern part of the Bering Sea across the Siberian Arctic coast to the Kara Sea and Kara River and further to the Pechora River drainage on the European side. Sendek DS (2021Phylogenetic relationships in vendace and least cisco, and their distribution areas in western Eurasia.''Annales Zoologici Fennici'' 58: 289–306. It has been introduced in some lakes and rivers in Uzbekistan and Kazakhstan. ''Coregonus sardinella'' is closely related to the European cisco or vendace ''Coregonus albula'', and also is close to the Siberian peled whitefish ''C. peled'' ...

Arctic Char
The Arctic char or Arctic charr (''Salvelinus alpinus'') is a cold-water fish in the family Salmonidae, native to alpine lakes and arctic and subarctic coastal waters. Its distribution is Circumpolar North. It spawns in freshwater and populations can be lacustrine, riverine, or anadromous, where they return from the ocean to their fresh water birth rivers to spawn. No other freshwater fish is found as far north; it is, for instance, the only fish species in Lake Hazen which extend up to on Ellesmere Island in the Canadian Arctic. It is one of the rarest fish species in Great Britain and Ireland, found mainly in deep, cold, glacial lakes, and is at risk there from acidification. In other parts of its range, such as the Nordic countries, it is much more common, and is fished extensively. In Siberia, it is known as ''golets'' () and it has been introduced in lakes where it sometimes threatens less hardy endemic species, such as the small-mouth char and the long-finned char ...
