North Bull Island
Bull Island (Irish: ''Oileán an Tairbh''), more properly North Bull Island (Irish: ''Oileán an Tairbh Thuaidh''), is an island located in Dublin Bay in Ireland, about 5 km long and 800 m wide, lying roughly parallel to the shore off Clontarf (including Dollymount), Raheny, Kilbarrack, and facing Sutton. The island, with a sandy beach known as Dollymount Strand running its entire length, is a relatively recent, and inadvertent, result of human intervention in the bay. The island lies within the jurisdiction of, and is mostly owned by, Dublin City Council, and is managed by the Council's Parks and Landscape Division. Bull Island, which is accessed by way of a causeway bridge from Raheny and a wooden bridge from Clontarf, has the most designations of any site in the country, as a National Bird Sanctuary, a biosphere reserve, a National Nature Reserve, a Special Protection Area under the EU Birds Directive, and a Special Area of Conservation under the EU Habitats Directive, ...

Irish Sea
The Irish Sea or , gv, Y Keayn Yernagh, sco, Erse Sie, gd, Muir Èireann , Ulster-Scots: ''Airish Sea'', cy, Môr Iwerddon . is an extensive body of water that separates the islands of Ireland and Great Britain. It is linked to the Celtic Sea in the south by St George's Channel and to the Inner Seas off the West Coast of Scotland in the north by the North Channel. Anglesey, North Wales, is the largest island in the Irish Sea, followed by the Isle of Man. The term ''Manx Sea'' may occasionally be encountered ( cy, Môr Manaw, ga, Muir Meann gv, Mooir Vannin, gd, Muir Mhanainn). On its shoreline are Scotland to the north, England to the east, Wales to the southeast, Northern Ireland and the Republic of Ireland to the west. The Irish Sea is of significant economic importance to regional trade, shipping and transport, as well as fishing and power generation in the form of wind power and nuclear power plants. Annual traffic between Great Britain and Ireland amounts t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Great South Wall
The Great South Wall ( ga, Balla an Bhulla Theas) (also sometimes called the South Bull Wall), at the Port of Dublin, extends from the tip of the Poolbeg peninsula more than four kilometres out into Dublin Bay. It was the world's longest sea wall at the time of its construction and remains one of the longest in Europe. It faces the newer Bull Wall, and has one of four port lighthouses at its end. History Background Dublin Bay had a long-running problem with silting, notably at the mouth of the River Liffey, and held major sand banks, notably the North Bull and South Bull (both ''hard sand dry at low water''), to either side of the Liffey mouth, along with the Kish Bank over 11 km out to sea. Between the North and South Bulls, a sand bar existed, rising over time, limiting access to the city quays. Furthermore, the shape of the Liffey estuary was rather different from the present day, with the river channel not fully enclosed, much of Pearse Street (then ''Lazey Hill'') r ...

Dublin Port And Docks Board
Dublin Port ( ga, Calafort Átha Cliath) is the seaport of Dublin, Ireland, of both historical and contemporary economic importance. Approximatively two-thirds of Ireland's port traffic travels via the port, which is by far the busiest on the island of Ireland. Location The modern Dublin Port is located either side of the River Liffey, out to its mouth. On the north side of the river, the main part () of the port lies at the end of East Wall and North Wall, from Alexandra Quay. The element of the port on the south side of the river is much smaller () and lies at the beginning of the Poolbeg peninsula. Access The port is served by road, with a direct connection from the Dublin Port Tunnel to the northern part (and so a connection with the M50 motorway). There is no passenger rail service to either part of Dublin Port but the northern part is served by freight rail. The northern part is also served by Dublin Bus, with route 53 and by a Luas terminus just outside the port ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Dublin Golf Club
The Royal Dublin Golf Club, founded in 1885, is Ireland's third oldest golf club. It is a private members' club, with an 18-hole links course on Bull Island, Dublin, Republic of Ireland, Ireland. The championship routing that we recognise today was by designed by Harry Colt in the 1920s. Over a three-year period from 2004 the links was extended under the guidance of golf architect Martin Hawtree. History Origins and early locations The Royal Dublin Golf Club was instituted at a meeting held at No. 19 Grafton Street in May 1885, pioneered by a Scottish banker - John Lumsden. Originally called Dublin Golf Club, it received its Royal designation in 1891, when there were 250 members paying an £2 annual subscription (after an entrance fee of 8 guineas). It was originally located near the Magazine Fort in the Phoenix Park, moved to Sutton after a year, and finally in 1889 moved to its present home on North Bull Island (the name may be derived from the locality, Clontarf, which in Ga ...

List Of Lighthouses In Ireland
This is a list of lighthouses in Ireland. The Commissioners of Irish Lights are responsible for the majority of marine navigation aids around the island though a small number are maintained by local harbour authorities. The main list identifies those lighthouses in a clockwise direction starting with Crookhaven, Crookhaven lighthouse, County Cork. Maintained by Commissioners of Irish Lights Maintained by other Irish marine authorities A smaller number of active lighthouses are operated by other authorities, primarily the port and harbour companies located around the Geography of Ireland, Irish coast. Inactive Improvements and changes to the aids to navigation around the Irish coast, has meant that there are a number of lighthouses that have been decommissioned. This list includes those where the tower or structure is still in existence. Some of these have been reused, such as Ferris Point which is now a vessel control tower.

Bull Wall
The Bull Wall ( ga, Balla an Bhulla), or North Bull Wall ( ga, Balla an Bhulla Thuaidh), at the Port of Dublin, extending from the estuary of the River Tolka and the district of Clontarf out nearly 3 km into Dublin Bay, is one of the two defining sea walls of the port, and faces the earlier-constructed Great South Wall. It has one of a trio of port lighthouses at the end of its extension breakwater, and a statue of ''Realt na Mara'' ('Mary, Queen of the Sea') partway along, and was responsible for the formation of North Bull Island with its nearly 5 km of beach. History Background Dublin Bay had a long-running problem with silting, including at the mouth of the River Liffey, and held major sand banks, notably the North Bull and South Bull, to either side of the Liffey mouth, along with the Kish Bank over 11 km out to sea. Between the North and South Bulls, a sand bar existed, rising over time, limiting access to the city quays. After years of primitive dredging, ...

George Halpin
George Halpin (Sr.) (1779? – 8 July 1854), was a prominent civil engineer and lighthouse builder, responsible for the construction of much of the Port of Dublin, several of Dublin's bridges, and a number of lighthouses; he is considered the founding father of the Irish lighthouse service. His son, , was also a well-known lighthouse builder. Biography Very little is known of Halpin's early life, though it is known that his background was in the building trade rather than in engineering. In 1800, he was made the Inspector of Works for the Dublin Ballast Board (the predecessor to the Commissioners of Irish Lights), succeeding Francis Tunstall, and in this capacity was responsible for a number of works.Skempton, p. 293 One of these, the Bull Wall, along with associated projects, led to the creation of Bull Island in Dublin Bay, and enabled deep-draught ships to use the port for the first time.Skempton, p. 294 Halpin was appointed the Inspector of Lighthouses in 1810.

North Bull Lighthouse, Dublin (geograph 5417369)
North is one of the four compass points or cardinal directions. It is the opposite of south and is perpendicular to east and west. ''North'' is a noun, adjective, or adverb indicating direction or geography. Etymology The word ''north'' is related to the Old High German ''nord'', both descending from the Proto-Indo-European unit *''ner-'', meaning "left; below" as north is to left when facing the rising sun. Similarly, the other cardinal directions are also related to the sun's position. The Latin word ''borealis'' comes from the Greek '' boreas'' "north wind, north", which, according to Ovid, was personified as the wind-god Boreas, the father of Calais and Zetes. ''Septentrionalis'' is from ''septentriones'', "the seven plow oxen", a name of ''Ursa Major''. The Greek ἀρκτικός (''arktikós'') is named for the same constellation, and is the source of the English word ''Arctic''. Other languages have other derivations. For example, in Lezgian, ''kefer'' can mean ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bull Wall Bridge, Clontarf - Geograph
A bull is an intact (i.e., not castrated) adult male of the species ''Bos taurus'' (cattle). More muscular and aggressive than the females of the same species (i.e., cows), bulls have long been an important symbol in many religions, including for sacrifices. These animals play a significant role in beef ranching, dairy farming, and a variety of sporting and cultural activities, including bullfighting and bull riding. Due to their temperament, handling requires precautions. Nomenclature The female counterpart to a bull is a cow, while a male of the species that has been castrated is a ''steer'', '' ox'', or ''bullock'', although in North America, this last term refers to a young bull. Use of these terms varies considerably with area and dialect. Colloquially, people unfamiliar with cattle may refer to both castrated and intact animals as "bulls". A wild, young, unmarked bull is known as a ''micky'' in Australia.Sheena Coupe (ed.), ''Frontier Country, Vol. 1'' (Weldon ...

Venturi Effect
The Venturi effect is the reduction in fluid pressure that results when a fluid flows through a constricted section (or choke) of a pipe. The Venturi effect is named after its discoverer, the 18th century Italian physicist, Giovanni Battista Venturi. Background In inviscid fluid dynamics, an incompressible fluid's velocity must ''increase'' as it passes through a constriction in accord with the principle of mass continuity, while its static pressure must ''decrease'' in accord with the principle of conservation of mechanical energy (Bernoulli's principle). Thus, any gain in kinetic energy a fluid may attain by its increased velocity through a constriction is balanced by a drop in pressure. By measuring pressure, the flow rate can be determined, as in various flow measurement devices such as Venturi meters, Venturi nozzles and orifice plates. Referring to the adjacent diagram, using Bernoulli's equation in the special case of steady, incompressible, inviscid flows (such as t ...

Ballast Board (Dublin)
Ballast is material that is used to provide stability to a vehicle or structure. Ballast, other than cargo, may be placed in a vehicle, often a ship or the gondola of a balloon or airship, to provide stability. A compartment within a boat, ship, submarine, or other floating structure that holds water is called a ballast tank. Water should move in and out from the ballast tank to balance the ship. In a vessel that travels on the water, the ballast will remain below the water level, to counteract the effects of weight above the water level. The ballast may be redistributed in the vessel or disposed of altogether to change its effects on the movement of the vessel. History The basic concept behind the ballast tank can be seen in many forms of aquatic life, such as the blowfish or members of the argonaut group of octopus. The concept has been invented and reinvented many times by humans to serve a variety of purposes. In the fifteenth and sixteenth century, the ballast "did not co ...
