Jack Sound
Jack Sound is a treacherous body of water about wide between the island of Skomer and the Pembrokeshire mainland that contains numerous reefs and a tidal race of up to 6 knots. It is used by boats to avoid a three-mile detour around the island, and has its share of sunken shipwrecks. The most popular wreck for 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. The sound is part of the Skomer Marine Conservation Zone Skomer Marine Conservation Zone is an underwater marine nature reserve located off the coast of Pembrokeshire in Wales.

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. Skomer is a national nature reserve (United Kingdom), national nature reserve, a Site of Special Scientific Interest and a Special Protection Area. It is surrounded by a marine nature reserve and is managed by the Wildlife Trust of South and West Wales. Skomer is known for its archaeological interest: stone circles, standing stone and remains of prehistoric houses. Much of the island has been designated an ancient monument. Description The island has an area of . Its highest point is above sea level at Gorse Hill, while the majority of the island sits at around above sea level. Skomer is intersected by ...

Pembrokeshire
Pembrokeshire ( ; cy, Sir Benfro ) is a Local government in Wales#Principal areas, county in the South West Wales, south-west of Wales. It is bordered by Carmarthenshire to the east, Ceredigion to the northeast, and the rest by sea. The county is home to Pembrokeshire Coast National Park. The Park occupies more than a third of the area of the county and includes the Preseli Hills in the north as well as the Pembrokeshire Coast Path. Historically, mining and fishing were important activities, while industry nowadays is focused on agriculture (86 per cent of land use), oil and gas, and tourism; Pembrokeshire's beaches have won many awards. The county has a diverse geography with a wide range of geological features, habitats and wildlife. Its prehistory and modern history have been extensively studied, from tribal occupation, through Roman times, to Welsh, Irish, Norman, English, Scandinavian and Flemish influences. Pembrokeshire County Council's headquarters are in the county ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, very large whirlpools develop, which can be extremely hazardous to navigation.

Scuba Diving
Scuba diving is a mode of underwater diving whereby divers use breathing equipment that is completely independent of a surface air supply. The name "scuba", an acronym for "Self-Contained Underwater Breathing Apparatus", was coined by Christian J. Lambertsen in a patent submitted in 1952. Scuba divers carry their own source of breathing gas, usually compressed air, affording them greater independence and movement than surface-supplied divers, and more time underwater than free divers. Although the use of compressed air is common, a gas blend with a higher oxygen content, known as enriched air or nitrox, has become popular due to the reduced nitrogen intake during long and/or repetitive dives. Also, breathing gas diluted with helium may be used to reduce the likelihood and effects of nitrogen narcosis during deeper dives. Open circuit scuba systems discharge the breathing gas into the environment as it is exhaled, and consist of one or more diving cylinders containing breat ...

Calcium Carbide
Calcium carbide, also known as calcium acetylide, is a chemical compound with the chemical formula of Ca C2. 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 CaC2 (the rest is CaO (calcium oxide), Ca3P2 (calcium phosphide), CaS (calcium sulfide), Ca3N2 (calcium nitride), SiC (silicon carbide), 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 (old no, Oddevold) is a town and the seat of Uddevalla Municipality in Västra Götaland County, Sweden. In 2015, it had a population of 34 781. It is located at a bay of the south-eastern part of Skagerrak. The beaches of Uddevalla are filled with seashells and Uddevalla has one of the largest shell-banks in the world. Uddevalla has a port and it once had a large shipyard, the ''Uddevallavarvet'' ("Uddevalla wharf"), which was the largest employer in Bohuslän during the 1960s. The 1970s recession, that affected the Swedish shipyard industry severely, led to the closing of the wharf in 1985. History Uddevalla received its town privileges in 1498, but thought to have been a place of trade long before that. Formerly, Uddevalla belonged to Norway, and its name today comes from the original Norwegian ''Oddevald'', which later turned into ''Oddevold''. Due to its close location to Sweden and Denmark, it was often besieged. In 1612, it was burnt down by Swedish troops led ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barry, Vale Of Glamorgan
Barry ( cy, Y Barri; ) is a town in the Vale of Glamorgan, Wales, on the north coast of the Bristol Channel approximately south-southwest of Cardiff. Barry is a seaside resort, with attractions including several beaches and the resurrected Barry Island Pleasure Park. According to Office for National Statistics 2016 estimate data, the population of Barry was 54,673. Once a small village, Barry has absorbed its larger neighbouring villages of Cadoxton and Barry Island, and now, Sully. It grew significantly from the 1880s with the development of Barry Docks, which in 1913 was the largest coal port in the world. Etymology The origin of the town's name is disputed. It may derive from the sixth-century Saint Baruc who was buried on Barry Island where a ruined chapel was dedicated to him. Alternatively, the name may derive from Welsh ', meaning "hill, summit". The name in Welsh includes the definite article. History Early history The area now occupied by Barry has seen human ac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Marine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
