Whirlpools
A whirlpool is a body of rotating water produced by opposing currents or a current running into an obstacle. Small whirlpools form when a bath or a sink is draining. More powerful ones formed in seas or oceans may be called maelstroms ( ). ''Vortex'' is the proper term for a whirlpool that has a downdraft. In narrow ocean straits with fast flowing water, whirlpools are often caused by tides. Many stories tell of ships being sucked into a maelstrom, although only smaller craft are actually in danger. Smaller whirlpools appear at river rapids and can be observed downstream of artificial structures such as weirs and dams. Large cataracts, such as Niagara Falls, produce strong whirlpools. Notable whirlpools Saltstraumen Saltstraumen is a narrow strait located close to the Arctic Circle, south-east of the city of Bodø, Norway. It has one of the strongest tidal currents in the world. Whirlpools up to in diameter and in depth are formed when the current is at its strongest. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vortex
In fluid dynamics, a vortex ( : vortices or vortexes) is a region in a fluid in which the flow revolves around an axis line, which may be straight or curved. Vortices form in stirred fluids, and may be observed in smoke rings, whirlpools in the wake of a boat, and the winds surrounding a tropical cyclone, tornado or dust devil. Vortices are a major component of turbulent flow. The distribution of velocity, vorticity (the curl of the flow velocity), as well as the concept of circulation are used to characterise vortices. In most vortices, the fluid flow velocity is greatest next to its axis and decreases in inverse proportion to the distance from the axis. In the absence of external forces, viscous friction within the fluid tends to organise the flow into a collection of irrotational vortices, possibly superimposed to larger-scale flows, including larger-scale vortices. Once formed, vortices can move, stretch, twist, and interact in complex ways. A moving vortex carries s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charybdis
Charybdis (; grc, Χάρυβδις, Khárybdis, ; la, Charybdis, ) is a sea monster in Greek mythology. She, with the sea monster Scylla, appears as a challenge to epic characters such as Odysseus, Jason, and Aeneas. Scholarship locates her in the Strait of Messina. The idiom "between Scylla and Charybdis" has come to mean being forced to choose between two similarly dangerous situations. Description The sea monster Charybdis was believed to live under a small rock on one side of a narrow channel. Opposite her was Scylla, another sea monster, that lived inside a much larger rock. The sides of the strait were within an arrow-shot of each other, and sailors attempting to avoid one of them would come in reach of the other. To be "between Scylla and Charybdis" therefore means to be presented with two opposite dangers, the task being to find a route that avoids both. Three times a day, Charybdis swallowed a huge amount of water, before belching it back out again, creating large whir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Corryvreckan Whirlpool - Geograph-2404815-by-Walter-Baxter
''The'' () is a grammatical article in English, denoting persons or things already mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with pronouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of pronoun ''thee'') when followed by a v ...

Værøy
Værøy is an island municipality in Nordland county, Norway. It is part of the traditional district of Lofoten. The administrative centre of the municipality is the village of Sørland on the main island of Værøya. The other village in Værøy is Nordland. Most of the residents live in the Sørland area surrounding the main harbor. The old Værøy Lighthouse sits at the end of that harbor. The municipality is the 351st largest by area out of the 356 municipalities in Norway. Værøy is the 347th most populous municipality in Norway with a population of only 678.

Firth Of Lorne
The Firth of Lorn or Lorne ( gd, An Linne Latharnach) is the inlet of the sea between the south-east coast of the Isle of Mull and the mainland of Scotland. It includes a number of islands, and is noted for the variety of wildlife habitats that are found. In 2005, a large part of the Firth became a Special Area of Conservation. Geography and geology The firth extends from the junction of the Sound of Mull and the Lynn of Lorn in the north-east, in a south-westerly direction towards Colonsay. The narrower north-eastern part is the Inner Firth, and the wider south-western part is the Outer Firth. The firth takes its name from the historic province of Lorne on the adjacent mainland. The Firth of Lorn is a continuation of the Great Glen - the Great Glen Fault runs along the north-westerm side of the firth. A conspicuous feature of the coasts of the firth is the presence of rock platforms and raised cliffs. These can be seen on the coast of Mull, on the Island of Kerrera and on ...

Scotland
Scotland (, ) is a country that is part of the United Kingdom. Covering the northern third of the island of Great Britain, mainland Scotland has a border with England to the southeast and is otherwise surrounded by the Atlantic Ocean to the north and west, the North Sea to the northeast and east, and the Irish Sea to the south. It also contains more than 790 islands, principally in the archipelagos of the Hebrides and the Northern Isles. Most of the population, including the capital Edinburgh, is concentrated in the Central Belt—the plain between the Scottish Highlands and the Southern Uplands—in the Scottish Lowlands. Scotland is divided into 32 administrative subdivisions or local authorities, known as council areas. Glasgow City is the largest council area in terms of population, with Highland being the largest in terms of area. Limited self-governing power, covering matters such as education, social services and roads and transportation, is devolved from the Scott ...

Gulf Of Corryvreckan
The Gulf of Corryvreckan (from the Gaelic ''Coire Bhreacain'', meaning 'cauldron of the speckled seas' or 'cauldron of the plaid'), also called the Strait of Corryvreckan, is a narrow strait between the islands of Jura and Scarba, in Argyll and Bute, off the west coast of mainland Scotland. It is possible for tourists to visit the site by way of boat trips from local harbours or sightseeing flights from Oban Airport. Topography Strong Atlantic currents and unusual underwater topography together produce a particularly intense tidal race in the Corryvreckan channel. As the flood tide enters the narrow area between the two islands it speeds up to and meets a variety of seabed features, including a deep hole and a rising pinnacle. These features combine to create whirlpools, standing waves and a variety of other surface effects. The Corryvreckan is the third largest whirlpool in the world, and is on the northern side of the gulf, surrounding a pyramid-shaped basalt pinnacle tha ...

Argyll And Bute
Argyll and Bute ( sco, Argyll an Buit; gd, Earra-Ghàidheal agus Bòd, ) is one of 32 unitary authority council areas in Scotland and a lieutenancy area. The current lord-lieutenant for Argyll and Bute is Jane Margaret MacLeod (14 July 2020). The administrative centre for the council area is in Lochgilphead at Kilmory Castle, a 19th-century Gothic Revival building and estate. The current council leader is Robin Currie, a councillor for Kintyre and the Islands. Description Argyll and Bute covers the second-largest administrative area of any Scottish council. The council area adjoins those of Highland, Perth and Kinross, Stirling and West Dunbartonshire. Its border runs through Loch Lomond. The present council area was created in 1996, when it was carved out of the Strathclyde region, which was a two-tier local government region of 19 districts, created in 1975. Argyll and Bute merged the existing Argyll and Bute district and one ward of the Dumbarton district. The Dumbart ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scarba
Scarba ( gd, Sgarba) is an island, in Argyll and Bute, Scotland, just north of the much larger island of Jura. The island was owned by Richard Hill, 7th Baron Sandys, and has not been permanently inhabited since the 1960s. It is now covered in heather and used for grazing animals. Kilmory Lodge is used seasonally as a shooting lodge, the island having a flourishing herd of red deer. The island's name is from the Norse and may mean "sharp, stony, hilly terrain" or "cormorant island".Mac an Tàilleir (2003) p. 104 Description Scarba is not served by any public ferries, but access from Craobh Haven or Crinan Harbour is possible by arrangement with local boatmen. The rough summit ridge can be accessed from the harbour at the north end, from where a vehicle track leads up past Kilmory Lodge to a height of about 200 metres. After that, there are no paths or well defined routes, and the terrain becomes rough and boggy. The island rises steeply to a peak (Cruach Scarba) of . A c ...

Jura, Scotland
Jura ( ; gd, Diùra; sco, Jura) is an island in the Inner Hebrides of Scotland, adjacent to and northeast of Islay. With an area of , and 196 inhabitants recorded in the 2011 census, Jura is more sparsely populated than Islay, and is one of the least densely populated islands of Scotland: in a list of the islands of Scotland ranked by size, Jura comes eighth, whereas by population it comes 31st. The island is mountainous, bare and largely infertile, covered by extensive areas of blanket bog. The main settlement is the east coast village of Craighouse. The Jura distillery, producing Isle of Jura single malt whisky, is in the village, as is the island's rum distillery which opened in 2021. Craighouse also houses the island's shop, church, primary school, the Jura hotel and bar, a gallery, craft shop, tearoom and the community run petrol pumps. North of Craighouse are a number of other small settlements on or near the east coast: Keils, Knockrome, Ardfernal, Lagg, Tarbert, ...

Strait
A strait is an oceanic landform connecting two seas or two other large areas of water. The surface water generally flows at the same elevation on both sides and through the strait in either direction. Most commonly, it is a narrow ocean channel that lies between two land masses. Some straits are not navigable, for example because they are either too narrow or too shallow, or because of an unnavigable reef or archipelago. Straits are also known to be loci for sediment accumulation. Usually, sand-size deposits occur on both the two opposite strait exits, forming subaqueous fans or deltas. Terminology The terms ''channel'', ''pass'', or ''passage'' can be synonymous and used interchangeably with ''strait'', although each is sometimes differentiated with varying senses. In Scotland, ''firth'' or ''Kyle'' are also sometimes used as synonyms for strait. Many straits are economically important. Straits can be important shipping routes and wars have been fought for control of them. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
