180th Meridian
The 180th meridian or antimeridian is the meridian 180° both east and west of the prime meridian in a geographical coordinate system. The longitude at this line can be given as either east or west. On Earth, these two meridians form a great circle that divides the earth into the Western and Eastern Hemispheres. The antimeridian mostly passes through the open waters of the Pacific Ocean, but also across land in Russia, Fiji, and Antarctica. An important function of this meridian is its use as the basis for the International Date Line, which snakes around national borders to maintain date consistency within the territories of Russia, the United States, Kiribati, Fiji and New Zealand. Starting at the North Pole of the Earth and heading south to the South Pole, the 180th meridian passes through: The meridian also passes between (but not particularly close to): *through the Aleutian Island chain of US territory *the Gilbert Islands and the Phoenix Islands of Kiriba ...

12-hour Clock
The 12-hour clock is a time convention in which the 24 hours of the day are divided into two periods: a.m. (from Latin , translating to "before midday") and p.m. (from Latin , translating to "after midday"). For different opinions on representation of midday and midnight, see #Confusion at noon and midnight Each period consists of 12 hours numbered: 12 (acting as 0), 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 and 11. The daily cycle starts at 12 midnight, runs through 12 noon, and continues until just before midnight at the end of the day. There is no widely accepted convention for how midday and midnight should be represented. The 12-hour clock was developed from the second millennium BC and reached its modern form in the 16th century AD. The 12-hour time convention is common in several English-speaking nations and former British colonies, as well as a few other countries. History and use The natural day-and-night division of a calendar day forms the fundamental basis as to why ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fiji
Fiji ( , ,; fj, Viti, ; Fiji Hindi: फ़िजी, ''Fijī''), officially the Republic of Fiji, is an island country in Melanesia, part of Oceania in the South Pacific Ocean. It lies about north-northeast of New Zealand. Fiji consists of an archipelago of more than 330 islands—of which about 110 are permanently inhabited—and more than 500 islets, amounting to a total land area of about . The most outlying island group is Ono-i-Lau. About 87% of the total population of live on the two major islands, Viti Levu and Vanua Levu. About three-quarters of Fijians live on Viti Levu's coasts: either in the capital city of Suva; or in smaller urban centres such as Nadi—where tourism is the major local industry; or in Lautoka, where the Sugarcane, sugar-cane industry is dominant. The interior of Viti Levu is sparsely inhabited because of its terrain. The majority of Fiji's islands were formed by Volcano, volcanic activity starting around 150 million years ago. Some geo ...

Cikobia-i-Lau
Cikobia-i-Lau, or Cirikalia, is an island in the Lau Islands in the north-east of Fiji. The island has historically been called Thikombia, Thimkombia-i-Lau or Farewell Island. Environment In the Quaternary period, Cikobia-i-Lau was one of the most seismically active islands in Fiji. In 1976 white-tailed tropic birds were using the islands cliffs as nest sites. The island is forested, has one village, as well as some caves, cliffs and gardens. In 2016 Cyclone Winston damaged the island and its infrastructure, and repairs supported by the Fijian and New Zealand governments began in March. Society In 1982 Cikobiai-Lau's islanders rescued a Californian family who had spent 25 days adrift before being stranded on a sand bar close to the island. Notable people In 2016 the head man was Ledua Sele.

Amchitka Pass
Amchitka Pass is a strait in Alaska, United States. It is located in the Aleutian Islands on the 180th meridian, between the Rat Islands group to the west and the Delarof Islands The Delarof Islands ( ale, Naahmiĝun tanangis; russian: Острова Деларова) (ca. ) are a group of small islands at the extreme western end of the Andreanof Islands group in the central Aleutian Islands, Alaska. The Delarofs consist ... to the east. Amchitka Pass has a least width of 50 miles (80.5 km) and depths of 249 feet (76 meters) to over 6,000 feet (1,829 meters). The islands on both sides of the pass should be cleared by at least 5 miles (8 km). Heavy tide rips have been observed off the east end of Amchitka Island. The pass is dangerous in heavy weather, particularly for small and medium craft; currents appear erratic in direction and velocities may be strong. This may account for reports of very large seas and strong tide rips. References Straits of Aleutians West Census Ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 shelves. The Bering Sea is named for Vitus Bering, a 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 Sea.

Chukchi Sea
Chukchi Sea ( rus, Чуко́тское мо́ре, r=Chukotskoye more, p=tɕʊˈkotskəjə ˈmorʲɪ), sometimes referred to as the Chuuk Sea, Chukotsk Sea or the Sea of Chukotsk, is a marginal sea of the Arctic Ocean. It is bounded on the west by the Long Strait, off Wrangel Island, and in the east by Point Barrow, Alaska, beyond which lies the Beaufort Sea. The Bering Strait forms its southernmost limit and connects it to the Bering Sea and the Pacific Ocean. The principal port on the Chukchi Sea is Uelen in Russia. The International Date Line crosses the Chukchi Sea from northwest to southeast. It is displaced eastwards to avoid Wrangel Island as well as the Chukotka Autonomous Okrug on the Russian mainland. Geography The sea has an approximate area of and is only navigable about four months of the year. The main geological feature of the Chukchi Sea bottom is the Hope Basin, which is bound to the northeast by the Herald Arch. Depths less than occupy 56% of the total a ...

Wrangel Island
Wrangel Island ( rus, О́стров Вра́нгеля, r=Ostrov Vrangelya, p=ˈostrəf ˈvrangʲɪlʲə; ckt, Умӄиԓир, translit=Umqiḷir) is an island of the Chukotka Autonomous Okrug, Russia. It is the 91st largest island in the world and roughly the size of Crete. Located in the Arctic Ocean between the Chukchi Sea and East Siberian Sea, the island lies astride the 180th meridian. The International Date Line is therefore displaced eastwards at this latitude to avoid the island as well as the Chukchi Peninsula on the Russian mainland, to keep the island on the same day as the rest of Russia. The closest land to Wrangel Island is the tiny and rocky Herald Island located to the east.Kosko, M.K., M.P. Cecile, J.C. Harrison, V.G. Ganelin, N.V., Khandoshko, and B.G.

Arctic Ocean
The Arctic Ocean is the smallest and shallowest of the world's five major oceans. It spans an area of approximately and is known as the coldest of all the oceans. The International Hydrographic Organization (IHO) recognizes it as an ocean, although some oceanographers call it the Arctic Mediterranean Sea. It has been described approximately as an estuary of the Atlantic Ocean. It is also seen as the northernmost part of the all-encompassing World Ocean. The Arctic Ocean includes the North Pole region in the middle of the Northern Hemisphere and extends south to about 60°N. The Arctic Ocean is surrounded by Eurasia and North America, and the borders follow topographic features: the Bering Strait on the Pacific side and the Greenland Scotland Ridge on the Atlantic side. It is mostly covered by sea ice throughout the year and almost completely in winter. The Arctic Ocean's surface temperature and salinity vary seasonally as the ice cover melts and freezes; its salinity is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
