Yukon Flats
The Yukon Flats are a vast area of wetlands, forest, bog, and low-lying ground centered on the confluence of the Yukon River, Porcupine River, and Chandalar River in the central portion of the U.S. state of Alaska. The Yukon Flats are bordered in the north by the Brooks Range, in the south by the White Mountains, and cover an area of approximately . The Yukon Flats are a critical waterfowl breeding ground due to the large area of wetland provided by the estimated 40,000 small lakes and streams in the area. In recognition of this fact, the area is protected under the Yukon Flats National Wildlife Refuge. The Yukon Flats straddle the Arctic Circle and have an extremely variable climate. Temperatures of 95 F (35 °C) are not uncommon in summer, while winter temperatures have been known to drop to -70 F (-57 °C). Several hundred Alaska Natives and others live in the Yukon Flats area. Though most of the region's people are concentrated in the villages of Fort Yukon, Venetie, Beaver ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yukon Flats National Wildlife Refuge
The Yukon Flats National Wildlife Refuge is a protected wetland area in the U.S. state of Alaska. It encompasses most of the Yukon Flats, a vast wetland area centered on the confluence of the Yukon River, Porcupine River, and Chandalar River. The area is a major waterfowl breeding ground, and after a proposal to flood the Yukon Flats via a dam on the Yukon River was turned down, the Yukon Flats were deemed worthy of protection. On 1 December 1978, US President Jimmy Carter designated the Yukon Flats as a National Monument on the basis of the Antiquities Act of 1906. In the course of the Alaska National Interest Lands Conservation Act of December 2, 1980, the area boundaries were changed after political criticism and the status was downgraded to that of a wildlife refuge. It is the third-largest National Wildlife Refuge in the United States, although it is less than one-half the size of either of the two largest, the Arctic National Wildlife Refuge, or the Yukon Delta National ...

Alaska Native
Alaska Natives (also known as Alaskan Natives, Native Alaskans, Indigenous Alaskans, Aboriginal Alaskans or First Alaskans) are the indigenous peoples of Alaska and include Iñupiat, Yupik, Aleut, Eyak, Tlingit, Haida, Tsimshian, and a number of Northern Athabaskan cultures. They are often defined by their language groups. Many Alaska Natives are enrolled in federally recognized Alaska Native tribal entities, who in turn belong to 13 Alaska Native Regional Corporations, who administer land and financial claims. Ancestors of Native Alaskans or Alaska Natives migrated into the area thousands of years ago, in at least two different waves. Some are descendants of the third wave of migration, in which people settled across the northern part of North America. They never migrated to southern areas. For this reason, genetic studies show they are not closely related to native peoples in South America. Alaska Natives came from Asia. Anthropologists have stated that their journey fr ...

Natural Gas
Natural gas (also called fossil gas or simply gas) is a naturally occurring mixture of gaseous hydrocarbons consisting primarily of methane in addition to various smaller amounts of other higher alkanes. Low levels of trace gases like carbon dioxide, nitrogen, hydrogen sulfide, and helium are also usually present. Natural gas is colorless and odorless, so odorizers such as mercaptan (which smells like sulfur or rotten eggs) are commonly added to natural gas supplies for safety so that leaks can be readily detected. Natural gas is a fossil fuel and non-renewable resource that is formed when layers of organic matter (primarily marine microorganisms) decompose under anaerobic conditions and are subjected to intense heat and pressure underground over millions of years. The energy that the decayed organisms originally obtained from the sun via photosynthesis is stored as chemical energy within the molecules of methane and other hydrocarbons. Natural gas can be burned fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crude Oil
Petroleum, also known as crude oil, or simply oil, is a naturally occurring yellowish-black liquid mixture of mainly hydrocarbons, and is found in geological formations. The name ''petroleum'' covers both naturally occurring unprocessed crude oil and petroleum products that consist of refined crude oil. A fossil fuel, petroleum is formed when large quantities of dead organisms, mostly zooplankton and algae, are buried underneath sedimentary rock and subjected to both prolonged heat and pressure. Petroleum is primarily recovered by oil drilling. Drilling is carried out after studies of structural geology, sedimentary basin analysis, and reservoir characterisation. Recent developments in technologies have also led to exploitation of other unconventional reserves such as oil sands and oil shale. Once extracted, oil is refined and separated, most easily by distillation, into innumerable products for direct use or use in manufacturing. Products include fuels such as gasoli ...

Arctic Circle
The Arctic Circle is one of the two polar circles, and the most northerly of the five major circles of latitude as shown on maps of Earth. Its southern equivalent is the Antarctic Circle. The Arctic Circle marks the southernmost latitude at which, on the December solstice, the shortest day of the year in the northern hemisphere, the sun will not rise all day, and on the June solstice, the longest day of the year in the northern hemisphere, the sun will not set. These phenomena are referred to as polar night and midnight sun respectively, and the further north one progresses, the more pronounced these effects become. For example, in the Russian port city of Murmansk, three degrees above the Arctic Circle, the sun does not rise for 40 successive days in midwinter. The position of the Arctic Circle is not fixed and currently runs north of the Equator. Its latitude depends on the Earth's axial tilt, which fluctuates within a margin of more than 2° over a 41,000-year per ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wetland
A wetland is a distinct ecosystem that is flooded or saturated by water, either permanently (for years or decades) or seasonally (for weeks or months). Flooding results in oxygen-free (anoxic) processes prevailing, especially in the soils. The primary factor that distinguishes wetlands from terrestrial land forms or Body of water, water bodies is the characteristic vegetation of aquatic plants, adapted to the unique anoxic hydric soils. Wetlands are considered among the most biologically diverse of all ecosystems, serving as home to a wide range of plant and animal species. Methods for assessing wetland functions, wetland ecological health, and general wetland condition have been developed for many regions of the world. These methods have contributed to wetland conservation partly by raising public awareness of the functions some wetlands provide. Wetlands occur naturally on every continent. The water in wetlands is either freshwater, brackish or saltwater. The main wetland ty ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
