St. David's Lighthouse
St. David's Lighthouse is an active 19th century lighthouse sited at the eastern end of St. David's Island on a hill overlooking the headland of St. David's in Bermuda. It is one of only two 'traditional lighthouses' in Bermuda, the other being Gibbs Hill Lighthouse at the south-western end of the main island, both lights are well known tourist attractions. History Construction started in 1876 and it became operational in 1879, it consists of an octagonal tower of local limestone with two galleries and a lantern room. Originally painted white, it now has a distinctive red band daymark half-way up the tower. The original wick-type burner was replaced in the 1920s by a hood vapour kerosene unit. With a focal height of above sea level, the main light can be seen for 15 nautical miles, and has a light characteristic of a flash of white light every two seconds. A second light at a slightly lower level, displays fixed red and green lights to mark offshore shoals. In 1940, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lighthouse
A lighthouse is a tower, building, or other type of physical structure designed to emit light from a system of lamps and lens (optics), lenses and to serve as a beacon for navigational aid, for maritime pilots at sea or on inland waterways. Lighthouses mark dangerous coastlines, hazardous shoals, reefs, rocks, and safe entries to harbors; they also assist in aerial navigation. Once widely used, the number of operational lighthouses has declined due to the expense of maintenance and has become uneconomical since the advent of much cheaper, more sophisticated and effective electronic navigational systems. History Ancient lighthouses Before the development of clearly defined ports, mariners were guided by fires built on hilltops. Since elevating the fire would improve the visibility, placing the fire on a platform became a practice that led to the development of the lighthouse. In antiquity, the lighthouse functioned more as an entrance marker to ports than as a warning signa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gibbs Hill Lighthouse
Built in 1844 by Cottam and Hallen of Cornwall Road, Lambeth; in their works within sight of Waterloo Bridge Erected by the Royal Engineers, the Gibb's Hill Lighthouse is the taller of two lighthouses on Bermuda, and one of the first lighthouses in the world to be made of cast-iron. This is because at that time, steel still was not able to be bent. The optic consists of a Fresnel lens from 1904 revolving on steel bearings. However, for most of its history, the lens revolved on a bed of 1,200 pounds of mercury. While it is certainly not extremely tall in lighthouse standards, the hill that it stands on is one of the highest on the island. The light's focal plane on Gibbs Hill Lighthouse, therefore, is at above sea level. Airplanes can see its flashes from over away. The lighthouse has 185 steps to the top in eight flights. Until 1964, most of the light was run by hand, but in June of that year, the whole system was automated and runs on electricity. Sixty-thousand people ascen ...

Daymark
A daymark is a navigational aid for sailors and pilots, distinctively marked to maximize its visibility in daylight. The word is also used in a more specific, technical sense to refer to a signboard or daytime identifier that is attached to a day beacon or other aid to navigation. In that sense, a daymark conveys to the mariner during daylight hours the same significance as does the aid's light or reflector at night. Standard signboard shapes are square, triangular and rectangular; and the standard colours are red, green, orange, yellow and black. Notable daymarks * Trinity House Obelisk * Kingswear Daymark * Tasku beacon tower * Keskiniemi beacon tower * Hiidenniemi beacon tower * Laitakari beacon tower * Herring Tower, Langness * Le Hocq * La Tour Cârrée * Scharhörnbake Symbols used on US charts Chart symbols used by the US National Oceanic and Atmospheric Administration Department, 2013.

Nautical Miles
A nautical mile is a unit of length used in air, marine, and space navigation, and for the definition of territorial waters. Historically, it was defined as the meridian arc length corresponding to one minute ( of a degree) of latitude. Today the international nautical mile is defined as exactly . The derived unit of speed is the knot, one nautical mile per hour. Unit symbol There is no single internationally agreed symbol, with several symbols in use. * M is used as the abbreviation for the nautical mile by the International Hydrographic Organization. * NM is used by the International Civil Aviation Organization. * nmi is used by the Institute of Electrical and Electronics Engineers and the United States Government Publishing Office. * nm is a non-standard abbreviation used in many maritime applications and texts, including U.S. Government Coast Pilots and Sailing Directions. It conflicts with the SI symbol for nanometre. History The word mile is from the Latin word for ... [...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 ...

Sanders and Berke seek the advice of lighthouse-keeper and treasure-hunter Romer Treece on the origin of the medallion; he identifies the item as Spanish and takes an interest in the young couple. The ampoule is noticed by the man who had rented diving equipment to Sanders and Berke, which in turn attr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Peter Benchley
Peter Bradford Benchley (May 8, 1940 – February 11, 2006) was an American author, screenwriter, and ocean activist. He is known for his bestselling novel '' Jaws'' and co-wrote its film adaptation with Carl Gottlieb. Several more of his works were also adapted for both cinema and television, including '' The Deep'', ''The Island'', ''Beast'', and '' White Shark.'' Later in life, Benchley expressed some regret for his tone in writing about sharks, which he felt indulged already present fear and false belief about sharks, and he became an advocate for marine conservation. Contrary to widespread rumor, Benchley did not believe that his writings contributed to shark depopulation, nor is there evidence that ''Jaws'' or any of his works did so. Early life Benchley was the son of Marjorie (née Bradford) and author Nathaniel Benchley and grandson of Algonquin Round Table founder Robert Benchley. His younger brother, Nat Benchley, is a writer and actor. Peter Benchley was an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
