Yukon–Kuskokwim Delta
The Yukon–Kuskokwim Delta is a river delta located where the Yukon and Kuskokwim rivers empty into the Bering Sea on the west coast of the U.S. state of Alaska. At approximately in size, it is one of the largest deltas in the world. It is larger than the Mississippi River Delta (which varies between 32,400 and 122,000 square kilometers or 12,500 and 47,100 sq mi); it is comparable in size to the entire U.S. state of Louisiana (135,700 square kilometers or 52,400 sq mi). The delta, which consists mainly of tundra, is protected as part of the Yukon Delta National Wildlife Refuge. The delta has approximately 25,000 residents. 85% of these are Alaska Natives: Yupik and Athabaskan people. The main population center and service hub is the city of Bethel, with an estimated population of around 6,219 (as of 2011). Bethel is surrounded by 49 smaller villages, with the largest villages consisting of over 1000 people. Most residents live a traditional subsistence lifestyle of hunting ...

Bethel, Alaska
Bethel () is a city in the U.S. state of Alaska, located on the Kuskokwim River approximately from where the river flows into Kuskokwim Bay. It is the largest community in western Alaska and in the Unorganized Borough and the List of cities in Alaska, eighth-largest in the state. Bethel has a population of 6,325 as of the 2020 United States census, 2020 census, up from 6,080 in 2010. Annual events in Bethel include the Kuskokwim 300 dogsled race; Camai, a Yup'ik dance festival held each spring; and the Bethel Fair held in August. History Southwestern Alaska has been the homelands of Yup'ik peoples and their ancestors for thousands of years. The residents of what became Bethel were called the Mamterillermiut, meaning "Smokehouse People", after their nearby fish smokehouse. In the late 19th century, the Alaska Commercial Company established a trading post in the town, called Mumtrekhlogamute, which had a population of 41 people by the 1880 United States census, 1880 census.

Regions Of Alaska
Alaska ( ) is a non-contiguous U.S. state on the northwest extremity of North America. Part of the Western United States region, it is one of the two non-contiguous U.S. states, alongside Hawaii. Alaska is also considered to be the northernmost, westernmost, and easternmost (the Aleutian Islands cross the 180th meridian into the eastern hemisphere) state in the United States. It borders the Canadian territory of Yukon and the province of British Columbia to the east. It shares a western maritime border, in the Bering Strait, with Russia's Chukotka Autonomous Okrug. The Chukchi and Beaufort Seas of the Arctic Ocean lie to the north, and the Pacific Ocean lies to the south. Technically, it is a semi-exclave of the U.S., and is the largest exclave in the world. Alaska is the largest U.S. state by area, comprising more total area than the following three largest states of Texas, California, and Montana combined, and is the seventh-largest subnational division in the world. ...

Landforms Of Kusilvak Census Area, Alaska
A landform is a land feature on the solid surface of the Earth or other planetary body. They may be natural or may be anthropogenic (caused or influenced by human activity). Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great oceanic basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, structure stratification, rock exposure, and soil type. Gross physical features or landforms include intuitive elements such as berms, cliffs, hills, mounds, peninsulas, ridges, rivers, valleys, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodi ...

MODIS
The Moderate Resolution Imaging Spectroradiometer (MODIS) is a satellite-based sensor used for earth and climate measurements. There are two MODIS sensors in Earth orbit: one on board the Terra (EOS AM) satellite, launched by NASA in 1999; and one on board the Aqua (EOS PM) satellite, launched in 2002. Since 2011, MODIS operations have been supplemented by VIIRS sensors, such as the one aboard Suomi NPP. The systems often conduct similar operations due to their similar designs and orbits (with VIIRS data systems deisgned to be compatible with MODIS), though they have subtle differences contributing to similar but not identical uses. The MODIS instruments were built by Santa Barbara Remote Sensing. They capture data in 36 spectral bands ranging in wavelength from 0.4 μm to 14.4 μm and at varying spatial resolutions (2 bands at 250 m, 5 bands at 500 m and 29 bands at 1 km). Together the instruments image the entire Earth every 1 to 2 days. They are designed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Snowmobile
A snowmobile, also known as a snowmachine (chiefly Alaskan), motor sled (chiefly Canadian), motor sledge, skimobile, snow scooter, or simply a sled is a motorized vehicle designed for winter travel and recreation on snow. Their engines normally drive a continuous track at the rear, while skis at the front provide directional control. The earliest snowmobiles were powered by readily available industrial four-stroke, air-cooled engines. These would quickly be replaced by lighter and more powerful two-stroke gasoline internal combustion engines and since the mid-2000s four-stroke engines had re-entered the market. The challenges of cross-country transportation in the winter led to the invention of an all-terrain vehicle specifically designed for travel across deep snow where other vehicles foundered. , the snowmobile market has been shared between the four large North American makers (Bombardier Recreational Products (BRP), Arctic Cat, Yamaha, and Polaris) and some specialized m ...

Bush Flying
Bush flying refers to aircraft operations carried out in the bush. Bush flying involves operations in rough terrain where there are often no prepared landing strips or runways, frequently necessitating that bush planes be equipped with abnormally large tires, skis, skids or any other equipment necessary for unpaved runway operation. It is the only viable way of delivering people and supplies into more difficult to reach, remote locations. Etymology This term ''bush'' has been used since the 19th century to describe remote wilderness area beyond clearings and settlements hence ''bush flying'' denotes flight operations carried out in such remote regions. In Australia, in particular, bush refers to areas that might be called forest or wilderness in other countries. Purpose Bush flying is the primary and sometimes the only method of access across Northern Canada, Western Canada, Alaska, the Australian Outback and many other parts of the world. History In Canada, the first real ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Poverty Threshold
The poverty threshold, poverty limit, poverty line, or breadline is the minimum level of income deemed adequate in a particular country. The poverty line is usually calculated by estimating the total cost of one year's worth of necessities for the average adult.Poverty Lines – Martin Ravallion, in The New Palgrave Dictionary of Economics, 2nd Edition, London: Palgrave Macmillan The cost of housing, such as the rent for an apartment, usually makes up the largest proportion of this estimate, so economists track the real estate market and other housing cost indicators as a major influence on the poverty line. Individual factors are often used to account for various circumstances, such as whether one is a parent, elderly, a child, married, etc. The poverty threshold may be adjusted annually. In practice, like the definition of poverty, the official or common understanding of the poverty line is significantly higher in developed countries than in developing countries. In Septembe ...

Intensive Gathering
Intensive gathering describes the tending-to of edible wild plants to assure their continuous availability at known, convenient locales. Intensive gathering methods include weeding, discouraging predators, pot-irrigation, and limited harvesting to ensure reproduction. The same system of methods is involved in cultivation, a process which additionally requires systematic soil preparation and planting to tending and harvesting. This human manipulation ultimately results in the domestication of involved plant life. Intensive gathering results in a higher total yield but at a lower efficiency compared to a highly mobile hunter-gatherer lifestyle. Thus, intensive gathering is a product of sedentism and increased population density. Intensive gathering of plant foods at the expense of hunting large game, which was becoming scarcer as population density increased, was common worldwide in the two millennia preceding agriculture. Archeological evidence of intensive gathering includes mark ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fishing
Fishing is the activity of trying to catch fish. Fish are often caught as wildlife from the natural environment (Freshwater ecosystem, freshwater or Marine ecosystem, marine), but may also be caught from Fish stocking, stocked Body of water, bodies of water such as Fish pond, ponds, canals, park wetlands and reservoirs. Fishing techniques include trawling, Longline fishing, longlining, jigging, Fishing techniques#Hand-gathering, hand-gathering, Spearfishing, spearing, Fishing net, netting, angling, Bowfishing, shooting and Fish trap, trapping, as well as Destructive fishing practices, more destructive and often Illegal, unreported and unregulated fishing, illegal techniques such as Electrofishing, electrocution, Blast fishing, blasting and Cyanide fishing, poisoning. The term fishing broadly includes catching aquatic animals other than fish, such as crustaceans (shrimp/lobsters/crabs), shellfish, cephalopods (octopus/squid) and echinoderms (starfish/sea urchins).
