Jack Sound
Jack Sound is a treacherous body of water between the island of Skomer and the Pembrokeshire coast in west Wales. It is popular with divers. Description The wide Sound (geography), sound is used by boats to avoid a three-mile detour around the island, but it contains numerous reefs and a tidal race of up to 6 knot (unit)s which consequently has resulted in numerous wrecks. The sound is part of the Skomer Marine Conservation Zone. Recorded wrecks The most popular wreck for scuba diving, divers is the MV ''Lucy'', which sank in good condition in February 1967 after being abandoned by its crew owing to its cargo of calcium carbide. The Netherlands-registered coaster, , was en route from Uddevalla, Sweden to Barry, Vale of Glamorgan, Barry. Coflein, the RCAHMW, Royal Commission's website records 32 wrecks associated with Jack Sound. One of these was the passenger ship ''Albion'' which struck rocks on passage through Jack Sound and was forced to beach further along the coast, wh ...

Skomer
Skomer () or Skomer Island is an island off the coast of Pembrokeshire, in the community of Marloes and St Brides in west Wales. It is well known for its wildlife: around half the world's population of Manx shearwaters nest on the island, the Atlantic puffin colony is the largest in southern Britain, and the Skomer vole (a subspecies of the bank vole) is unique to the island.

Sound (geography)
In geography, a sound is a smaller body of water usually connected to a sea or an ocean. A ''sound'' may be an inlet that is deeper than a bight and wider than a fjord; or a narrow sea channel or an ocean channel between two land masses, such as a strait; or also a lagoon 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. These sounds are more appropriately called rias. 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 the landward end than the seaward end, due to g ...

Tidal Race
Tidal race or tidal rapid is a natural occurrence whereby a fast-moving tide passes through a constriction, resulting in the formation of waves, eddies and hazardous currents. The constriction can be a passage where the sides narrow, for example the Gulf of Corryvreckan and the Saltstraumen maelstrom, or an underwater obstruction (a reef or rising seabed), such as is found at the Portland Race in the United Kingdom. In extreme cases, such as Skookumchuck Narrows in British Columbia, through which tides can travel at more than 17 knots (31.484 km/h), very large whirlpools develop, which can be extremely hazardous to navigation.

Knot (unit)
The knot () is a unit of speed equal to one nautical mile per hour, exactly (approximately or ). The ISO standard symbol for the knot is kn. The same symbol is preferred by the Institute of Electrical and Electronics Engineers ( IEEE), while kt is also common, especially in aviation, where it is the form recommended by the International Civil Aviation Organization ( ICAO). The knot is a non- SI unit. The knot is used in meteorology, and in maritime and air navigation. A vessel travelling at 1 knot along a meridian travels approximately one minute of geographic latitude in one hour. Definitions ;1 international knot = :1 nautical mile per hour (by definition), : (exactly), : (approximately), : (approximately), : (approximately) : (approximately). The length of the internationally agreed nautical mile is . The US adopted the international definition in 1954, having previously used the US nautical mile ().

Skomer Marine Conservation Zone
Skomer Marine Conservation Zone is an underwater marine nature reserve located off the coast of Pembrokeshire in Wales. The nature reserve completely surrounds the islands of Skomer and Middleholm, and encompasses the mainland coastline around the end of the Marloes peninsula, including the small bay of Martin's Haven. The sea bed and rocky shelves of the island are teeming with life. Common eelgrass, ''Zostera marina'', one of the very few plants that flower underwater, grows on beds of sand and gravel in sheltered waters and its long, grass-like leaves form underwater lawns that provide food and shelter for other plants and animals. Species of lobsters, crabs and other crustaceans abound, and grey seals give birth on the coast in October and November. History Although the island of Skomer had long been a protected area, the Marine Nature Reserve was not established until 1990. It was one of only three Marine Nature Reserves in United Kingdom. Since the introduction of Marin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scuba Diving
Scuba diving is a Diving mode, mode of underwater diving whereby divers use Scuba set, breathing equipment that is completely independent of a surface breathing gas supply, and therefore has a limited but variable endurance. The word ''scuba'' is an Acronym#Normal case and acronyms, acronym for "Self-Contained Underwater Breathing Apparatus" and was coined by Christian J. Lambertsen in a patent submitted in 1952. Scuba divers carry their own source of breathing gas, affording them greater independence and movement than surface-supplied divers, and more time underwater than freedivers. Although the use of compressed air is common, other gas blends are also used. Open-circuit scuba systems discharge the breathing gas into the environment as it is exhaled and consist of one or more diving cylinders containing breathing gas at high pressure which is supplied to the diver at ambient pressure through a diving regulator. They may include additional cylinders for range extension, de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Calcium Carbide
Calcium carbide, also known as calcium acetylide, is a chemical compound with the chemical formula of . Its main use industrially is in the production of acetylene and calcium cyanamide. The pure material is colorless, while pieces of technical-grade calcium carbide are grey or brown and consist of about 80–85% of (the rest is CaO ( calcium oxide), ( calcium phosphide), CaS ( calcium sulfide), ( calcium nitride), SiC (silicon carbide), C (carbon), etc.). In the presence of trace moisture, technical-grade calcium carbide emits an unpleasant odor reminiscent of garlic. Applications of calcium carbide include manufacture of acetylene gas, generation of acetylene in carbide lamps, manufacture of chemicals for fertilizer, and steelmaking. Production Calcium carbide is produced industrially in an electric arc furnace from a mixture of lime and coke at approximately . This is an endothermic reaction requiring per mole and high temperatures to drive off the carbon monoxide. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uddevalla
Uddevalla is a Stad (Sweden), town in Västra Götaland County, Sweden. It’s the seat of Uddevalla Municipality. In 2015, it had a population of 34,781, making it the largest town fully in Bohuslän. Uddevalla is located where the river Bäveån opens up into Byfjorden, a fjord in the south-eastern part of Skagerrak. The beaches of Uddevalla are filled with seashells and Uddevalla has one of the largest shell-Bank (geography), banks in the world. Uddevalla also has a port that once was a large shipyard, the ''Uddevallavarvet'' ("Uddevalla wharf"), which was the largest employer in Bohuslän during the 1960s. History Uddevalla originally belonged to Norway and received its town privileges in 1498. It’s probable that the town was founded some time before that, but we have no proof about that. The Norwegians originally named the city “Oddevald”, which later became “Oddevold”. Due to the town’s former proximity to Denmark and Sweden, as well as its strategic positio ...
