Clestrain Sound
Clestrain Sound is a strait between Mainland Orkney and the Isle of Graemsay within the Orkney Islands, Scotland. Clestrain Sound lies in the western entrance to Scapa Flow. Like other seaways within the Orkney Islands, Clestrain Sound has been recognized for many years to be warmed by the North Atlantic Drift current.J. Gunn, ''Orkney, the Magnetic North'', Thomas Nelson and Sons, Edinburgh (1932) See also *Mill of Ayreland *Burn of Ayreland The Burn of Ayreland (or Ireland) is a northwesterly flowing coastal stream on Mainland Orkney, Scotland, that discharges to the Clestrain Sound about two miles south of Stenness.

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mainland Orkney
The Mainland, also known as Hrossey and Pomona, is the main island of Orkney, Scotland. Both of Orkney's burghs, Kirkwall and Stromness, lie on the island, which is also the heart of Orkney's ferry and air connections. Seventy-five per cent of Orkney's population live on the island, which is more densely populated than the other islands of the archipelago. The lengthy history of the island's occupation has provided numerous important archaeological sites and the sandstone bedrock provides a platform for fertile farmland. There is an abundance of wildlife, especially seabirds. Etymology The name Mainland is a corruption of the Old Norse . Formerly the island was also known as meaning 'horse island'. The island is sometimes referred to as '' Pomona'' (or ''Pomonia''), a name that stems from a 16th-century mis-translation by George Buchanan.Buchanan, George (1582''Rerum Scoticarum Historia: The First Book''The University of California, Irvine.

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 th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Graemsay
Graemsay () is an island in the western approaches to Scapa Flow, in the Orkney Islands of Scotland. The island has two lighthouses. Graemsay lies within the parish of Stromness. Geography and geology Graemsay lies between Hoy and Stromness on Mainland Orkney, separated from the Mainland by Clestrain Sound. The island is in area and is mainly crofted. The island's geology is Old Red Sandstone of the Devonian period, with two volcanic faults. On the north coast there is granite- schist, a great rarity in Orkney. Graemsay is surrounded by strong tidal races, known locally as ''roosts''. An Orkney Ferries service, usually operated by , links the island with Stromness and Moaness on Hoy. Graemsay is sometimes referred to locally, as 'Orkney's green isle' due to its lush green vegetation cover. Wildlife Birds include oystercatchers, ringed plovers, redshank and curlew. Parts of the island are largely undeveloped and are a haven for wild plants. History As with many o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orkney Islands
Orkney (; sco, Orkney; on, Orkneyjar; nrn, Orknøjar), also known as the Orkney Islands, is an archipelago in the Northern Isles of Scotland, situated off the north coast of the island of Great Britain. Orkney is 10 miles (16 km) north of the coast of Caithness and has about 70 islands, of which 20 are inhabited. The largest island, the Mainland, has an area of , making it the sixth-largest Scottish island and the tenth-largest island in the British Isles. Orkney’s largest settlement, and also its administrative centre, is Kirkwall. Orkney is one of the 32 council areas of Scotland, as well as a constituency of the Scottish Parliament, a lieutenancy area, and an historic county. The local council is Orkney Islands Council, one of only three councils in Scotland with a majority of elected members who are independents. The islands have been inhabited for at least years, originally occupied by Mesolithic and Neolithic tribes and then by the Picts. Orkney wa ...

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 ...

Scapa Flow
Scapa Flow viewed from its eastern end in June 2009 Scapa Flow (; ) is a body of water in the Orkney Islands, Scotland, sheltered by the islands of Mainland, Graemsay, Burray,S. C. George, ''Jutland to Junkyard'', 1973. South Ronaldsay and Hoy. Its sheltered waters have played an important role in travel, trade and conflict throughout the centuries. Vikings anchored their longships in Scapa Flow more than a thousand years ago. It was the United Kingdom's chief naval base during the First and Second World Wars, but the facility was closed in 1956. Scapa Flow has a shallow sandy bottom not deeper than and most of it is about deep; it is one of the great natural harbours and anchorages of the world, with sufficient space to hold a number of navies. The harbour has an area of and contains just under 1 billion cubic metres of water. Since the scuttling of the German fleet after World War I, its wrecks and their marine habitats form an internationally acclaimed di ...

Sound (geography)
In geography, a sound is a smaller body of water typically connected to a larger sea or ocean. There is little consistency in the use of "sound" in English-language place names. It can refer to an inlet, deeper than a bight and wider than a fjord, or a narrow sea or ocean channel between two bodies of land (similar to a strait), or it can refer to the lagoon located between a barrier island and the mainland. Overview A sound is often formed by the seas flooding a river valley. This produces a long inlet where the sloping valley hillsides descend to sea-level and continue beneath the water to form a sloping sea floor. The Marlborough Sounds in New Zealand are good examples of this type of formation. Sometimes a sound is produced by a glacier carving out a valley on a coast then receding, or the sea invading a glacier valley. The glacier produces a sound that often has steep, near vertical sides that extend deep underwater. The sea floor is often flat and deeper at ...

North Atlantic Current
The North Atlantic Current (NAC), also known as North Atlantic Drift and North Atlantic Sea Movement, is a powerful warm western boundary current within the Atlantic Ocean that extends the Gulf Stream northeastward. The NAC originates from where the Gulf Stream turns north at the Southeast Newfoundland Rise, a submarine ridge that stretches southeast from the Grand Banks of Newfoundland. The NAC flows northward east of the Grand Banks, from 40°N to 51°N, before turning sharply east to cross the Atlantic. It transports more warm tropical water to northern latitudes than any other boundary current; more than 40 Sv () in the south and 20 Sv () as it crosses the Mid-Atlantic Ridge. It reaches speeds of near the North American coast. Directed by topography, the NAC meanders heavily, but in contrast to the meanders of the Gulf Stream, the NAC meanders remain stable without breaking off into eddies. The colder parts of the Gulf Stream turn northward near the "tail" of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
