Atlantic Ocean
The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about . It covers approximately 20% of Earth's surface and about 29% of its water surface area. It is known to separate the " Old World" of Africa, Europe and Asia from the "New World" of the Americas in the European perception of the World. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and North and South America to the west. As one component of the interconnected World Ocean, it is connected in the north to the Arctic Ocean, to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south (other definitions describe the Atlantic as extending southward to Antarctica). The Atlantic Ocean is divided in two parts, by the Equatorial Counter Current, with the North(ern) Atlantic Ocean and the South(ern) Atlantic Ocean split at about 8°N.

Virgin Islands
The Virgin Islands ( es, Islas Vírgenes) are an archipelago in the Caribbean Sea. They are geologically and biogeographically the easternmost part of the Greater Antilles, the northern islands belonging to the Puerto Rico Trench and St. Croix being a displaced part of the same geologic structure. Politically, the British Virgin Islands have been governed as the western island group of the Leeward Islands, which are the northern part of the Lesser Antilles, and form the border between the Caribbean Sea and the Atlantic Ocean. The archipelago is separated from the true Lesser Antilles by the Anegada Passage and from the main island of Puerto Rico by the Virgin Passage. The islands fall into three different political jurisdictions: * Virgin Islands, informally referred to as British Virgin Islands, a British overseas territory, * Virgin Islands of the United States, an unincorporated territory of the United States, * Spanish Virgin Islands, the easternmost islands of the Comm ...

British Overseas Territory
The British Overseas Territories (BOTs), also known as the United Kingdom Overseas Territories (UKOTs), are fourteen dependent territory, territories with a constitutional and historical link with the United Kingdom. They are the last remnants of the former British Empire and do not form part of the United Kingdom itself. The permanently inhabited territories are internally Self-governance, self-governing, with the United Kingdom retaining responsibility for Defence (military), defence and foreign relations. Three of the territories are inhabited only by a transitory population of military or scientific personnel. All but one of the rest are listed by the Special Committee on Decolonization, UN Special Committee on Decolonization as United Nations list of non-self-governing territories, non-self-governing territories. All fourteen have the Monarchy of the United Kingdom, British monarch as head of state. three territories (the Falkland Islands, Gibraltar and the Akrotiri an ...

Atlantic Time Zone
The Atlantic Time Zone is a geographical region that keeps standard time—called Atlantic Standard Time (AST)—by subtracting four hours from Coordinated Universal Time ( UTC), resulting in UTC−04:00. AST is observed in parts of North America and some Caribbean islands. During part of the year, some portions of the zone observe daylight saving time, referred to as Atlantic Daylight Time (ADT), by moving their clocks forward one hour to result in UTC−03:00. The clock time in this zone is based on the mean solar time of the 60th meridian west of the Greenwich Observatory. In Canada, the provinces of New Brunswick, Nova Scotia, and Prince Edward Island are in this zone, though legally they calculate time specifically as an offset of four hours from Greenwich Mean Time (GMT–4) rather than from UTC. Small portions of Quebec (eastern Côte-Nord and the Magdalen Islands) also observe Atlantic Time. Officially, the entirety of Newfoundland and Labrador observes Newfoundland Stand ...

Island
An island (or isle) is an isolated piece of habitat that is surrounded by a dramatically different habitat, such as water. Very small islands such as emergent land features on atolls can be called islets, skerries, cays or keys. An island in a river or a lake island may be called an eyot or ait, and a small island off the coast may be called a holm. Sedimentary islands in the Ganges delta are called chars. A grouping of geographically or geologically related islands, such as the Philippines, is referred to as an archipelago. There are two main types of islands in the sea: continental and oceanic. There are also artificial islands, which are man-made. Etymology The word ''island'' derives from Middle English ''iland'', from Old English ''igland'' (from ''ig'' or ''ieg'', similarly meaning 'island' when used independently, and -land carrying its contemporary meaning; cf. Dutch ''eiland'' ("island"), German ''Eiland'' ("small island")). However, the spelling of the word ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caribbean
The Caribbean (, ) ( es, El Caribe; french: la Caraïbe; ht, Karayib; nl, De Caraïben) is a region of the Americas that consists of the Caribbean Sea, its islands (some surrounded by the Caribbean Sea and some bordering both the Caribbean Sea and the North Atlantic Ocean) and the surrounding coasts. The region is southeast of the Gulf of Mexico and the North American mainland, east of Central America, and north of South America. Situated largely on the Caribbean Plate, the region has more than 700 islands, islets, reefs and cays (see the list of Caribbean islands). Island arcs delineate the eastern and northern edges of the Caribbean Sea: The Greater Antilles and the Lucayan Archipelago on the north and the Lesser Antilles and the on the south and east (which includes the Leeward Antilles). They form the West Indies with the nearby Lucayan Archipelago (the Bahamas and Turks and Caicos Islands), which are considered to be part of the Caribbean despite not bordering the Caribbe ...

Virgin Gorda
Virgin Gorda () is the third-largest island (after Tortola and Anegada) and second-most populous of the British Virgin Islands (BVI). Geography Located at about 18 degrees, 48 minutes North, and 64 degrees, 30 minutes West, it covers an area of about . The main commercial and residential area is Spanish Town on the southwestern part of the island. An unusual geologic formation known as "the Baths" located on the southern end of the island makes Virgin Gorda one of the BVI's major tourist destinations. At the Baths, in spite of evidence of the island's largely volcanic origins, huge granite boulders lie in piles on the beach, forming scenic grottoes that are open to the sea. Granite is an intrusive igneous rock, thus not volcanic. It did form from magma, however, at great depth. Granite becomes exposed at the Earth's surface only after geologic ages of erosion removes the overburden. At the surface, weathering has broken the granite into large boulders and rounded their su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dog Islands
Dog Islands are a small group of islets among the British Virgin Islands in the Caribbean. The islands originally received their names from sailors who heard barking when they moored there, and assumed that they must be dogs. However, the barking noises were made by Caribbean monk seals. The sailors also regarded the Caribbean monk seal as a good source of fresh seal meat, and as a result, they are now extinct. Geography The Dog Islands are situated about north east off the main island of Tortola and about off the north west of Virgin Gorda in the strait Sir Francis Drake Channel. The coordinates of the main islet are 18°28′96″N and 64°27′70″W. The uninhabited islets are of volcanic origin and have a total area of about The group consist of 5 islets: * Great Dog Island, main islet, about * George Dog Island, about * West Dog Island, about :and the subgroup Seal Dogs about north east off Great Dog Island with * East Seal Dog Island, about and ...

Roseate Tern
The roseate tern (''Sterna dougallii'') is a species of tern in the family Laridae. The genus name ''Sterna'' is derived from Old English "stearn", "tern", and the specific ''dougallii'' refers to Scottish physician and collector Dr Peter McDougall (1777–1814). "Roseate" refers to the bird's pink breast in breeding plumage. Taxonomy English naturalist George Montagu described the roseate tern in 1813. Genetically, it is most closely related to the white-fronted tern (''S. striata''), with their common ancestor a sister lineage to the black-naped tern (''S. sumatrana''). This species has a number of geographical races, differing mainly in bill colour and minor plumage details. ''S. d. dougallii '' breeds on the Atlantic coasts of Europe and North America, and winters south to the Caribbean and west Africa. Both the European and North American populations have been in long term decline, though active conservation measures have reversed the decline in the last few years at som ...

Reef Flat
A fringing reef is one of the three main types of coral reef. It is distinguished from the other main types, barrier reefs and atolls, in that it has either an entirely shallow backreef zone (lagoon) or none at all. If a fringing reef grows directly from the shoreline, then the reef flat extends to the beach and there is no backreef. In other cases (e.g., most of the Bahamas), fringing reefs may grow hundreds of yards from shore and contain extensive backreef areas within which it contains food and water, examples are Philippines, Indonesia, Timor-Leste, the western coast of Australia, the Caribbean, East Africa, and Red Sea. Charles Darwin believed that fringing reefs are the first kind of reefs to form around a landmass in a long-term reef growth process.Kennedy, D.M. and Woodroffe, C.D. 2002.Fringing reef growth and morphology: a review. ''Earth-Science Reviews''. 57:255-277. The largest fringing coral reef in the world is the Ningaloo Reef, stretching to around along the coas ...

Montastrea Cavernosa
''Montastraea'' is a genus of colonial stony coral found in the Caribbean seas. It is the only genus in the monotypic family Montastraeidae and contains a single species, ''Montastraea cavernosa'', known as great star coral. It forms into massive boulders and sometimes develops into plates. Its polyps are the size of a human thumb and fully extend at night. Description Great star coral colonies form massive boulders and domes over 5 feet (1.5 m) in diameter in waters of shallow and moderate depths. In deeper waters, this coral has been observed growing as a plate formation. It is found throughout most reef environments, and is the predominant coral at depths of 40–100 feet (12.2-30.5 m). This coral occasionally has a fluorescent red or orange color during daytime; it has recently been suggested that this hue is due to phycoerythrin, a cyanobacterial protein. It appears that, in addition to symbiotic zooxanthella, this coral harbors endocellular symbiotic cyanobacteria, possi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
