Saint Lawrence Island
St. Lawrence Island ( ess, Sivuqaq, russian: Остров Святого Лаврентия, Ostrov Svyatogo Lavrentiya) is located west of mainland Alaska in the Bering Sea, just south of the Bering Strait. The village of Gambell, Alaska, Gambell, located on the northwest cape of the island, is from the Chukchi Peninsula in the Russian Far East. The island is part of Alaska, but closer to Russia than to the Alaskan mainland. St. Lawrence Island is thought to be one of the last exposed portions of the Bering land bridge, land bridge that once joined Asia with North America during the Pleistocene period. It is the List of islands of the United States by area, sixth largest island in the United States and the List of islands by area, 113th largest island in the world. It is considered part of the Bering Sea Volcanic Province. The Saint Lawrence Island shrew (''Sorex jacksoni'') is a species of shrew endemic to St. Lawrence Island.

Bering Sea
The Bering Sea (, ; rus, Бе́рингово мо́ре, r=Béringovo móre) is a marginal sea of the Northern Pacific Ocean. It forms, along with the Bering Strait, the divide between the two largest landmasses on Earth: Eurasia and The Americas. It comprises a deep water basin, which then rises through a narrow slope into the shallower water above the continental shelf, continental shelves. The Bering Sea is named for Vitus Bering, a Denmark, Danish navigator in Russian service, who, in 1728, was the first European to systematically explore it, sailing from the Pacific Ocean northward to the Arctic Ocean. The Bering Sea is separated from the Gulf of Alaska by the Alaska Peninsula. It covers over and is bordered on the east and northeast by Alaska, on the west by the Russian Far East and the Kamchatka Peninsula, on the south by the Alaska Peninsula and the Aleutian Islands and on the far north by the Bering Strait, which connects the Bering Sea to the Arctic Ocean's Chukchi ...

Operational Navigation Chart D-10, 4th Edition
An operational definition specifies concrete, replicable procedures designed to represent a construct. In the words of American psychologist S.S. Stevens (1935), "An operation is the performance which we execute in order to make known a concept." For example, an operational definition of "fear" (the construct) often includes measurable physiologic responses that occur in response to a perceived threat. Thus, "fear" might be operationally defined as specified changes in heart rate, galvanic skin response, pupil dilation, and blood pressure. Overview An operational definition is designed to model or represent a concept or theoretical definition, also known as a construct. Scientists should describe the operations (procedures, actions, or processes) that define the concept with enough specificity such that other investigators can replicate their research. Operational definitions are also used to define system states in terms of a specific, publicly accessible process of preparation ...

Harpoon
A harpoon is a long spear-like instrument and tool used in fishing, whaling, seal hunting, sealing, and other marine hunting to catch and injure large fish or marine mammals such as seals and whales. It accomplishes this task by impaling the target animal and securing it with barb or toggling claws, allowing the fishermen to use a rope or chain attached to the projectile to catch the animal. A harpoon can also be used as a weapon. Certain harpoons are made with different builds to perform better with the type of target being aimed at. For example, the Inuit have short, fixed foreshaft harpoons for hunting seals at their breathing holes while loose shafted ones are made for attaching to the game thrown at. History In the 1990s, harpoon points, known as the Semliki harpoons or the Katanda harpoons, were found in the Katanda_Territory, Katanda region in Zaire (called the Democratic Republic of the Congo today). As the earliest known harpoons, these weapons were made and used 90, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ivory
Ivory is a hard, white material from the tusks (traditionally from elephants) and teeth of animals, that consists mainly of dentine, one of the physical structures of teeth and tusks. The chemical structure of the teeth and tusks of mammals is the same, regardless of the species of origin, but ivory contains structures of mineralised collagen. The trade in certain teeth and tusks other than elephant is well established and widespread; therefore, "ivory" can correctly be used to describe any mammalian teeth or tusks of commercial interest which are large enough to be carved or scrimshawed. Besides natural ivory, ivory can also be produced synthetically, hence (unlike natural ivory) not requiring the retrieval of the material from animals. Tagua nuts can also be carved like ivory. The trade of finished goods of ivory products has its origins in the Indus Valley. Ivory is a main product that is seen in abundance and was used for trading in Harappan civilization. Finished ivory pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Arctic Yo-yo
An Eskimo yo-yo or Alaska yo-yo ( esu, yuuyuuk; ik, igruuraak) is a traditional two-balled skill toy played and performed by the Eskimo-speaking Alaska Natives, such as Inupiat, Siberian Yupik, and Yup'ik. It resembles fur-covered bolas and yo-yo. It is regarded as one of the most simple, yet most complex, cultural artifacts/toys in the world.Kiana, Chris (2004/2016). ''Original 100 Alaska Eskimo Yo-Yo Stratagems: Instructional Book''. Publication Consultants. ASIN: B007SNYM38. /. andKeynote Speaker: Christopher (Chris) J. Kiana, M.B.A., MA-RD, Ph.D., candidate, ''WCSpeakers.com'' (accessed: December 01 2016). The Eskimo yo-yo involves simultaneously swinging two sealskin balls suspended on caribou sinew strings in opposite directions with one hand. It is popular with Alaskans and tourists alike.Klistoff, Alysa J. (2007), Weapon, Toy, or Art? The Eskimo yo-yo as a commodified Arctic bola and marker of cultural Identity'.

Alaska Native Claims Settlement Act
The Alaska Native Claims Settlement Act (ANCSA) was signed into law by President Richard Nixon on December 18, 1971, constituting at the time the largest land claims settlement in United States history. ANCSA was intended to resolve long-standing issues surrounding aboriginal land claims in Alaska, as well as to stimulate economic development throughout Alaska."Recognition of aboriginal land rights in Alaska was a sharp departure from American Indian policy in other parts of the US. Observers believe this was more a result of slow economic development within Alaska than rejection of Indian policy," citing Cooley, R.A. 1983. "Evolution of Alaska land policy." in Morehouse, T. A. (editor). ''Alaskan Resources Development: Issues of the 1980s''. Boulder: Westview Press, pp. 13-49. The settlement established Alaska Native claims to the land by transferring titles to twelve Alaska Native regional corporations and over 200 local village corporations. A thirteenth regional corporation was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polynya
A polynya () is an area of open water surrounded by sea ice. It is now used as a geographical term for an area of unfrozen seawater within otherwise contiguous pack ice or fast ice. It is a loanword from the Russian полынья (), which refers to a natural ice hole and was adopted in the 19th century by polar explorers to describe navigable portions of the sea. There are two main types of polynyas: coastal polynyas, which can be found year-round near the Antarctic and Arctic coasts and are mainly created by strong winds pushing the ice away from the coast, and mid-sea or open-ocean polynyas, which may be found more sporadically in the middle of ice pack in certain locations, especially around Antarctica. These locations are generally preconditioned by certain oceanic dynamics. One of the most famous mid-sea polynyas is the Weddell Polynya, also known as the Maud Rise Polynya, which occurs in the Lazarev Sea over the Maud Rise seamount. It was first spotted in September 197 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Seabird
Seabirds (also known as marine birds) are birds that are adapted to life within the marine environment. While seabirds vary greatly in lifestyle, behaviour and physiology, they often exhibit striking convergent evolution, as the same environmental problems and feeding niches have resulted in similar adaptations. The first seabirds evolved in the Cretaceous period, and modern seabird families emerged in the Paleogene. In general, seabirds live longer, breed later and have fewer young than other birds do, but they invest a great deal of time in their young. Most species nest in colonies, which can vary in size from a few dozen birds to millions. Many species are famous for undertaking long annual migrations, crossing the equator or circumnavigating the Earth in some cases. They feed both at the ocean's surface and below it, and even feed on each other. Seabirds can be highly pelagic, coastal, or in some cases spend a part of the year away from the sea entirely. Seabirds and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arctic Willow
''Salix arctica'', the Arctic willow, is a tiny creeping willow (family Salicaceae). It is adapted to survive in Arctic conditions, specifically tundras. Description ''S. arctica'' is typically a low shrub growing to only in height, rarely to , although it may reach in height in the Pacific Northwest. It has round, shiny green leaves long and broad; they are pubescent, with long, silky, silvery hairs. Like the rest of the willows, Arctic willow is dioecious, with male and female catkins on separate plants. As a result, the plant's appearance varies; the female catkins are red-coloured, while the male catkins are yellow-coloured.Jepson Flora''Salix arctica''/ref> Despite its small size, it is a long-lived plant, growing extremely slowly in the severe arctic climate; one in eastern Greenland was found to be 236 years old. Hybrids with '' Salix arcticola'' and ''Salix glauca'' are known. Distribution and habitat The Arctic willow grows in tundra and rocky moorland, and is th ...

United States Census, 2000
The United States census of 2000, conducted by the Census Bureau, determined the resident population of the United States on April 1, 2000, to be 281,421,906, an increase of 13.2 percent over the 248,709,873 people enumerated during the 1990 census. This was the twenty-second federal census and was at the time the largest civilly administered peacetime effort in the United States. Approximately 16 percent of households received a "long form" of the 2000 census, which contained over 100 questions. Full documentation on the 2000 census, including census forms and a procedural history, is available from the Integrated Public Use Microdata Series. This was the first census in which a state – California – recorded a population of over 30 million, as well as the first in which two states – California and Texas – recorded populations of more than 20 million.
