Tolka (Taz)
The Tolka (russian: Толька; Selkup: Толь-кы) is a river in the Yamalo-Nenets Autonomous Okrug, Russia. It has a length of and a drainage basin area of . The river flows north of the Arctic Circle, across territories of the Krasnoselkupsky District marked by permafrost and swamps. Course The Tolka is one of the main tributaries of the Taz. It is formed in the Siberian Uvaly hills, at the confluence of rivers Ai-Emtoryogan and Pyantymyogan. In its upper course the river heads roughly westwards across the tundra. After a long stretch it bends and meanders in a northeastern direction. Finally, south of the shore of lake Lake Chyortovo (Lozil-To), it bends eastwards, meandering until it meets the left bank of the Taz from its mouth in the Taz Estuary of the Kara Sea. Google Earth Tributaries The main tributaries of the Tolka are the long Varky-Chyuelky (Варкы-Чюэлькы) and the long Kypa-Kelilky (Кыпа-Кэлилькы) on the left. There are nume ...

Operational Navigation Chart
An aeronautical chart is a map designed to assist in the navigation of aircraft, much as nautical charts do for watercraft, or a roadmap does for drivers. Using these charts and other tools, pilots are able to determine their position, safe altitude, best route to a destination, navigation aids along the way, alternative landing areas in case of an in-flight emergency, and other useful information such as radio frequencies and airspace boundaries. There are charts for all land masses on Earth, and long-distance charts for trans-oceanic travel. Specific charts are used for each phase of a flight and may vary from a map of a particular airport facility to an overview of the instrument routes covering an entire continent (e.g., global navigation charts), and many types in between. Visual flight charts are categorized according to their scale, which is proportional to the size of the area covered by one map. The amount of detail is necessarily reduced when larger areas are represe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meander
A meander is one of a series of regular sinuous curves in the channel of a river or other watercourse. It is produced as a watercourse erodes the sediments of an outer, concave bank ( cut bank) and deposits sediments on an inner, convex bank which is typically a point bar. The result of this coupled erosion and sedimentation is the formation of a sinuous course as the channel migrates back and forth across the axis of a floodplain. The zone within which a meandering stream periodically shifts its channel is known as a meander belt. It typically ranges from 15 to 18 times the width of the channel. Over time, meanders migrate downstream, sometimes in such a short time as to create civil engineering challenges for local municipalities attempting to maintain stable roads and bridges.Neuendorf, K.K.E., J.P.

Google Earth
Google Earth is a computer program that renders a 3D representation of Earth based primarily on satellite imagery. The program maps the Earth by superimposing satellite images, aerial photography, and GIS data onto a 3D globe, allowing users to see cities and landscapes from various angles. Users can explore the globe by entering addresses and coordinates, or by using a keyboard or mouse. The program can also be downloaded on a smartphone or tablet, using a touch screen or stylus to navigate. Users may use the program to add their own data using Keyhole Markup Language and upload them through various sources, such as forums or blogs. Google Earth is able to show various kinds of images overlaid on the surface of the earth and is also a Web Map Service client. In 2019, Google has revealed that Google Earth now covers more than 97 percent of the world, and has captured 10 million miles of Street View imagery. In addition to Earth navigation, Google Earth provides a series ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taz Estuary
The Taz Estuary (russian: Тазовская губа) is a long gulf formed by the Taz River. It consists of a roughly long estuary that begins in the area of the settlement of Tazovsky and ends in the Gulf of Ob, which is connected with the Kara Sea. Its average width is about and it is one of the biggest estuaries in the world. It begins in the mouths of the Taz and the Pur Rivers in a roughly north–south direction at a latitude of 67° 30' N, and it bends westwards at a latitude of 69° N, widening further before joining the Gulf of Ob. The Russian Gazprom company is investing in the expansion of gas production in the Taz Estuary area, where there are said to be huge reserves. The area of the estuary was explored early.

Tundra
In physical geography, tundra () is a type of biome where tree growth is hindered by frigid temperatures and short growing seasons. The term ''tundra'' comes through Russian (') from the Kildin Sámi word (') meaning "uplands", "treeless mountain tract". There are three regions and associated types of tundra: Arctic tundra, alpine tundra, and Antarctic tundra. Tundra vegetation is composed of dwarf shrubs, sedges, grasses, mosses, and lichens. Scattered trees grow in some tundra regions. The ecotone (or ecological boundary region) between the tundra and the forest is known as the tree line or timberline. The tundra soil is rich in nitrogen and phosphorus. The soil also contains large amounts of biomass and decomposed biomass that has been stored as methane and carbon dioxide in the permafrost, making the tundra soil a carbon sink. As global warming heats the ecosystem and causes soil thawing, the permafrost carbon cycle accelerates and releases much of these soil-conta ...

Siberian Uvaly
Siberian Uvaly (russian: Сибирские Увалы) is a hilly region in the central part of the West Siberian Plain, Russia. A sector of the hills is a protected area under the name Upper Taz Nature Reserve, which was established in December 1986. The area is sparsely populated. Only a few settlements, such as Beloyarsky town, are located in the Siberian Uvaly. Geography The hilly area falls within the Khanty-Mansi and Yamalo-Nenets Autonomous Okrugs of Tyumen Oblast. It extends roughly from west to east between the Ob and the basin of the Yeloguy river, a tributary of the Yenisei. The Central Ob Lowland (Средне-Обская низменность) stretches to the south and the Nadym and Taz lowlands to the north. The Uvaly form a drainage divide between the right tributaries of the Ob and the upper course of the Kazym, Nadym, Pur and Taz river basins. The word "Uval" (russian: Увал) refers to an elongated hill with a flat, slightly convex or wavy top and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Permafrost
Permafrost is ground that continuously remains below 0 °C (32 °F) for two or more years, located on land or under the ocean. Most common in the Northern Hemisphere, around 15% of the Northern Hemisphere or 11% of the global surface is underlain by permafrost, with the total area of around 18 million km2. This includes substantial areas of Alaska, Greenland, Canada and Siberia. It can also be located on mountaintops in the Southern Hemisphere and beneath ice-free areas in the Antarctic. Permafrost does not have to be the first layer that is on the ground. It can be from an inch to several miles deep under the Earth's surface. It frequently occurs in ground ice, but it can also be present in non-porous bedrock. Permafrost is formed from ice holding various types of soil, sand, and rock in combination. Permafrost contains large amounts of biomass and decomposed biomass that has been stored as methane and carbon dioxide, making tundra soil a carbon sink. As global ...
