Cabo Prior Lighthouse
Cabo Prior Lighthouse ('' Cape Nerium'' ''as described by Strabo next to the Magnus portus Artabrorum, Artabri and most northwestern point in Iberia as Strabo says just about the same latitude as the Pyrenees'' ), ( es, Faro de Cabo Prior) is an active 19th century Spanish lighthouse located on the cabo or cape of the same name in the parish of San Martiño de Covas in the Ferrol municipality of the Province of A Coruña, Galicia. The lighthouse has been constructed on a high coastal clifftop, some northwest of Ferrol. A set of steps descends from the lighthouse down the steep cliff to a viewpoint overlooking the Atlantic Ocean. History Even though it wasn't till the 19th century that the modern lighthouse was built, the geographers of antiquity already took noticed of this granite-protuberance off the most northwestern point of Iberia which not just then, as described by Strabo and other classical geographers, was used as a reference point to bring to an end the Iber ...

Province Of A Coruña
The province of A Coruña (; es, La Coruña ; historical en, link=no, Corunna) is the northwesternmost province of Spain, and one of the four provinces which constitute the autonomous community of Galicia. This province is surrounded by the Atlantic Ocean to the west and north, Pontevedra Province to the south and Lugo Province to the east. History The history of this province starts at the end of the Middle Ages during the reign of the Catholic Monarchs of Spain. During those years this province was far smaller than today. This is because in the 1833 territorial division of Spain the entire Province of Betanzos together with half of the Mondoñedo were amalgamated into one single province with its capital city in A Coruña. Since 1833, the province has always been the one with the largest population and largest coast. Until the second half of the 20th century, this province was both the religious and cultural centre of the entire region. The University of Santiago de ...

Phoenicia
Phoenicia () was an ancient thalassocratic civilization originating in the Levant region of the eastern Mediterranean, primarily located in modern Lebanon. The territory of the Phoenician city-states extended and shrank throughout their history, and they possessed several enclaves such as Arwad and Tell Sukas (modern Syria). The core region in which the Phoenician culture developed and thrived stretched from Tripoli and Byblos in northern Lebanon to Mount Carmel in modern Israel. At their height, the Phoenician possessions in the Eastern Mediterranean stretched from the Orontes River mouth to Ashkelon. Beyond its homeland, the Phoenician civilization extended to the Mediterranean from Cyprus to the Iberian Peninsula. The Phoenicians were a Semitic-speaking people of somewhat unknown origin who emerged in the Levant around 3000 BC. The term ''Phoenicia'' is an ancient Greek exonym that most likely described one of their most famous exports, a dye also known as Tyrian purpl ...

Port Authority
In Canada and the United States, a port authority (less commonly a port district) is a governmental or quasi-governmental public authority for a special-purpose district usually formed by a legislative body (or bodies) to operate ports and other transportation infrastructure. In Canada, the federal Minister of Transport selects the local chief executive board member and the rest of the board is appointed at the recommendation of port users to the federal Minister; while all Canadian port authorities have a federal or Crown charter called '' Letters Patent''. Numerous Caribbean nations have port authorities, including those of Aruba, British Virgin Islands, Bahamas, Jamaica, Cayman Islands, Trinidad and Tobago, St. Lucia, St. Maarten, St. Vincent and the Grenadines. Central and South America also have port agencies such as ''autoridad'' and ''consorcio'' (authority and consortium). In Mexico, the federal government created sixteen port administrations in 1994–1995 called ''Admin ... [...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 red, ...

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] |

Lighthouse Keeper
A lighthouse keeper or lightkeeper is a person responsible for tending and caring for a lighthouse, particularly the light and lens in the days when oil lamps and clockwork mechanisms were used. Lighthouse keepers were sometimes referred to as "wickies" because of their job trimming the wicks. Duties and functions Historically, lighthouse keepers were needed to trim the wicks, replenish fuel, wind clockworks and perform maintenance tasks such as cleaning lenses and windows. They were also responsible for the fog signal and the weather station, and played a major role in search and rescue at sea. Because most lighthouses are located in remote, isolated or inaccessible areas on islands and coastlines, it was typical for the work of lighthouse keeper to remain within a family, passing from parents to child, all of whom lived in or near the lighthouse itself. "Stag light" was an unofficial term given to some isolated lighthouses in the United States Lighthouse Service. It meant sta ...

Foghorn
A foghorn or fog signal is a device that uses sound to warn vehicles of navigational hazards such as rocky coastlines, or boats of the presence of other vessels, in foggy conditions. The term is most often used in relation to marine transport. When visual navigation aids such as lighthouses are obscured, foghorns provide an audible warning of rock outcrops, shoals, headlands, or other dangers to shipping. Description All foghorns use a vibrating column of air to create an audible tone, but the method of setting up this vibration differs. Some horns, such as the Daboll trumpet, used vibrating plates or metal reeds, a similar principle to a modern electric car horn. Others used air forced through holes in a rotating cylinder or disk, in the same manner as a siren. Semi-automatic operation of foghorns was achieved by using a clockwork mechanism (or "coder") to sequentially open the valves admitting air to the horns; each horn was given its own timing characteristics to help marine ...

Electromagnetic
In physics, electromagnetism is an interaction that occurs between particles with electric charge. It is the second-strongest of the four fundamental interactions, after the strong force, and it is the dominant force in the interactions of atoms and molecules. Electromagnetism can be thought of as a combination of electrostatics, electricity and magnetism, two distinct but closely intertwined phenomena. In essence, electric forces occur between any two charged particles, causing an attraction between particles with opposite charges and repulsion between particles with the same charge, while magnetism is an interaction that occurs exclusively between ''moving'' charged particles. These two effects combine to create electromagnetic fields in the vicinity of charge particles, which can exert influence on other particles via the Lorentz force. At high energy, the weak force and electromagnetic force are unified as a single electroweak interaction, electroweak force. The electroma ...

Watt
The watt (symbol: W) is the unit of power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantify the rate of energy transfer. The watt is named after James Watt (1736–1819), an 18th-century Scottish inventor, mechanical engineer, and chemist who improved the Newcomen engine with his own steam engine in 1776. Watt's invention was fundamental for the Industrial Revolution. Overview When an object's velocity is held constant at one metre per second against a constant opposing force of one newton, the rate at which work is done is one watt. : \mathrm In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere (A) flows across an electrical potential difference of one volt (V), meaning the watt is equivalent to the volt-ampere (the latter unit, however, is used for a different quantity from the real power of an electrical circuit). : ...
