Inner And Outer Dowsing Sand Banks
The Inner and Outer Dowsing sand banks are shallow-water shoals off the Lincolnshire coast of the UK sector of southern North Sea. They have been used for navigation, as a commercial fishery, for aggregate dredging, and more recently as the location for major offshore wind farms. Dowsing banks and shoals The Inner Dowsing Bank is 7.5 km long north to south by 3.0 km wide. The centre of the bank is about 13 km north-east off Ingoldmells Point, Lincolnshire. The water depth ranges from 1 m to 30 m below sea-level. The Inner Dowsing Bank together with the adjacent Race Bank and North Ridge Bank have been designated a Special Area of Conservation (SAC) and a Marine Protected Area (MPA). The Inner Dowsing sandbank comprises coarse sand with areas of gravel, its elongated shape is maintained by the tidal currents. The Outer Dowsing Shoal is a shallow-water sand bank, aligned north-west to south-east. The shoal is about 19.5 km long and is rarely more than 1 k ...

Shoal
In oceanography, geomorphology, and geoscience, a shoal is a natural submerged ridge, bank, or bar that consists of, or is covered by, sand or other unconsolidated material and rises from the bed of a body of water to near the surface. It often refers to those submerged ridges, banks, or bars that rise near enough to the surface of a body of water as to constitute a danger to navigation. Shoals are also known as sandbanks, sandbars, or gravelbars. Two or more shoals that are either separated by shared troughs or interconnected by past or present sedimentary and hydrographic processes are referred to as a shoal complex.Neuendorf, K.K.E., J.P. Mehl Jr., and J.A. Jackson, eds. (2005) ''Glossary of Geology'' (5th ed.). Alexandria, Virginia, American Geological Institute. 779 pp. The term ''shoal'' is also used in a number of ways that can be either similar or quite different from how it is used in geologic, geomorphic, and oceanographic literature. Sometimes, this term refer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radar Beacon
Radar beacon (short: racon) is – according to ''article 1.103'' of the International Telecommunication Union's (ITU) ITU Radio Regulations (RR) – defined as "A transmitter-receiver associated with a fixed navigational mark which, when triggered by a radar, automatically returns a distinctive signal which can appear on the display of the triggering radar, providing range, bearing and identification information." Each ''station'' (transmitter-receiver, transceiver or transponder) shall be classified by the ''service'' in which it operates permanently or temporarily. Principle of operation When a racon receives a radar pulse, it responds with a signal on the same frequency which puts an image on the radar display. This takes the form of a short line of dots and dashes forming a Morse character radiating away from the location of the beacon on the normal plan position indicator radar display. The length of the line usually corresponds to the equivalent of a few nautica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fishing Areas Of The North Sea
Fishing is the activity of trying to catch fish. Fish are often caught as wildlife from the natural environment, but may also be caught from stocked bodies of water such as ponds, canals, park wetlands and reservoirs. Fishing techniques include hand-gathering, spearing, netting, angling, shooting and trapping, as well as more destructive and often illegal techniques such as electrocution, blasting and poisoning. The term fishing broadly includes catching aquatic animals other than fish, such as crustaceans (shrimp/lobsters/ crabs), shellfish, cephalopods (octopus/squid) and echinoderms ( starfish/sea urchins). The term is not normally applied to harvesting fish raised in controlled cultivations (fish farming). Nor is it normally applied to hunting aquatic mammals, where terms like whaling and sealing are used instead. Fishing has been an important part of human culture since hunter-gatherer times, and is one of the few food production activities that have persisted fr ...

Lightvessel Stations Of Great Britain
The history of the many lightvessel stations of Great Britain goes back over 250 years to the placement of the world's first lightship at the Nore in the early 18th century. A lightvessel station is a named position at which a lightvessel was placed, rather than a particular ship; individual vessels were often transferred between different stations during their existence. Stations themselves were occasionally changed, especially during wartime, when lights were only displayed in response to specific shipping needs. History The world's first lightvessel was the result of a business partnership between Robert Hamblin, a former barber and ship manager from King's Lynn, and David Avery, an investor.Naish, J. M. ''Seamarks: Their History and Development'', Stanford Maritime, 1985, , p. 107 In 1730 the pair secured a government licence to moor a ship, with a prominent light affixed to it, to serve as a navigation aid at the Nore in the Thames mouth. Hamblin and Avery intended to prof ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fisher Bank
The Fisher Bank is a sand bank in the North Sea, off the west coast of Denmark. It consists of ''Great Fisher Bank'', and ''Little Fisher Bank'' (the latter closer to Danish coast). Some older charts refer to them as the "Great Fishing Bank" and the "Little Fishing Bank". As ''Fisher'' it gives its name to one of the sea areas in the British Shipping Forecast. Location Sea area Fisher is defined by the co-ordinates: * 56°00'N 08°10'E * 56°00'N 04°00'E * 57°45'N 04°00'E * 57°45'N 07°30'E * 57°05'N 08°35'E and the Danish coast. Character As its name suggests, these large sandbanks provide rich fishing grounds, but overfishing has left them less productive than they were, and many Danish fishing vessels have moved elsewhere, into the North Sea or the Baltic.

Dogger Bank
Dogger Bank (Dutch: ''Doggersbank'', German: ''Doggerbank'', Danish: ''Doggerbanke'') is a large sandbank in a shallow area of the North Sea about off the east coast of England. During the last ice age the bank was part of a large landmass connecting mainland Europe and the British Isles, now known as Doggerland. It has long been known by fishermen to be a productive fishing bank; it was named after the '' doggers'', medieval Dutch fishing boats especially used for catching cod. At the beginning of the 21st century the area was identified as a potential site for a UK round 3 wind farm, being developed as Dogger Bank Wind Farm. Name The name Dogger Bank was first recorded in the mid-17th century. It is probably derived from the word " dogger" used for a two-masted boat of the type that trawled for fish in the area in medieval times. The area has similar names in Dutch, German, and Danish. It gives its name to the Dogger sea area used in the BBC Radio 4 Shipping Forecast. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nore
The Nore is a long bank of sand and silt running along the south-centre of the final narrowing of the Thames Estuary, England. Its south-west is the very narrow Nore Sand. Just short of the Nore's easternmost point where it fades into the channels it has a notable point once marked by a lightship on the line where the estuary of the Thames nominally becomes the North Sea. A lit buoy today stands on this often map-marked divisor: between Havengore Creek in east Essex and Warden Point on the Isle of Sheppey in Kent. Until 1964 it marked the seaward limit of the Port of London Authority. As the sandbank was a major hazard for shipping coming in and out of London, in 1732 it received the world's first lightship. This became a major landmark, and was used as an assembly point for shipping. Today it is marked by Sea Reach No. 1 Buoy. The Nore is an anchorage, or open roadstead, used by the Royal Navy's North Sea Fleet, and to its local Command. It was the site of a notorious mu ...

HMS Cobra (1899)
HMS ''Cobra'' was a Steam turbine, turbine-powered destroyer of the Royal Navy. She was built speculatively by Armstrong Whitworth and then offered for sale to the British Admiralty. She was launched on 28 June 1899, and purchased by the Navy on 8 May 1900 for £70,000. Her short career came to an end when she broke her back and sank near South Dowsing Shoal, off Ingoldmells, on 18 September 1901. The break occurred from her bows, between the two aft boilers. Twelve men — including the chief engineer — were saved; 44 Navy officers and men, as well as 23 staff from the contractors, mostly employees of the turbine manufacturers, Parsons Marine, were drowned. A court-martial enquiry held in October absolved the surviving officers of all blame, finding that "''Cobra'' did not touch the ground or come into any contact with any obstruction, nor was her loss due to any error in navigation, but was due to structural weakness of the ship." This was contested by the manufacturers and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Light Characteristic
A light characteristic is all of the properties that make a particular navigational light identifiable. Graphical and textual descriptions of navigational light sequences and colours are displayed on nautical charts and in Light Lists with the chart symbol for a lighthouse, lightvessel, buoy or sea mark with a light on it. Different lights use different colours, frequencies and light patterns, so mariners can identify which light they are seeing. Abbreviations While light characteristics can be described in prose, e.g. "Flashing white every three seconds", lists of lights and navigation chart annotations use abbreviations. The abbreviation notation is slightly different from one light list to another, with dots added or removed, but it usually follows a pattern similar to the following (see the chart to the right for examples). * An abbreviation of the type of light, e.g. "Fl." for flashing, "F." for fixed. * The color of the light, e.g. "W" for white, "G" for green, "R" for re ...
