Ambrose Channel Pilot Cable
The Ambrose Channel pilot cable, also called the Ambrose Channel leader cable, was a cable laid in Ambrose Channel at the entrance to the Port of New York and New Jersey that provided an audio tone for guiding ships in and out of port at times of low visibility. The cable was laid during 1919 and 1920; it had been removed from the channel and replaced by wireless technology by the end of the 1920s. Background Ambrose Channel is the only shipping channel into and out of the Port of New York and New Jersey, an important commercial port. Delays posed a major problem for shipping en route to New York City, and bad weather could close the channel for days. Ships were forced to wait at the harbor's entrance for conditions to clear. These delays cost shipping companies substantial amounts of money, with each ship costing between $500 and $4000 per hour it was stopped (roughly $5,700 to $46,000 in 2013 dollars). Description and operation The Ambrose leader cable was an armored cable w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diagram Of Holland Channel Cable
A diagram is a symbolic representation of information using visualization techniques. Diagrams have been used since prehistoric times on walls of caves, but became more prevalent during the Enlightenment. Sometimes, the technique uses a three-dimensional visualization which is then projected onto a two-dimensional surface. The word ''graph'' is sometimes used as a synonym for diagram. Overview The term "diagram" in its commonly used sense can have a general or specific meaning: * ''visual information device'' : Like the term "illustration", "diagram" is used as a collective term standing for the whole class of technical genres, including graphs, technical drawings and tables. * ''specific kind of visual display'' : This is the genre that shows qualitative data with shapes that are connected by lines, arrows, or other visual links. In science the term is used in both ways. For example, Anderson (1997) stated more generally: "diagrams are pictorial, yet abstract, representat ...

Naval Submarine Base New London
Naval Submarine Base New London is the primary United States Navy East Coast submarine base, also known as the "Home of the Submarine Force." It is located in Groton, Connecticut directly across the Thames River from its namesake city of New London. History In 1868, the State of Connecticut gave the Navy of land along the Thames River in Groton to build a Naval Station. Due to a lack of federal funding, it was not until 1872 that two brick buildings and a T-shaped pier were constructed and officially declared a Navy Yard. In 1898, Congress approved a coaling station to be built at the Yard for refueling small naval ships traveling through the waters of New England. The Navy Yard was first used for laying up inactive ships. The Congressional appropriations were small and the Navy had little need for the yard, which was closed from 1898 to 1900 and its personnel reassigned. By 1912, oil replaced coal in warships and again the Yard was scheduled for closure and the land relinqui ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Maritime Pilot
A maritime pilot, marine pilot, harbor pilot, port pilot, ship pilot, or simply pilot, is a mariner who maneuvers ships through dangerous or congested waters, such as harbors or river mouths. Maritime pilots are regarded as skilled professionals in navigation as they are required to know immense details of waterways such as depth, currents, and hazards, as well as displaying expertise in handling ships of all types and size. Obtaining the title 'maritime pilot' requires being an expert ship handler licensed or authorised by a recognised pilotage authority. History The word ''pilot'' is believed to have come from the Middle French, ''pilot'', ''pillot'', from Italian, ''pilota'', from Late Latin, ''pillottus''; ultimately from Ancient Greek πηδόν (pēdón, "blade of an oar, oar"). The work functions of the pilot can be traced back to Ancient Greece and Rome, when locally experienced harbour captains, mainly local fishermen, were employed by incoming ships' captains to b ...

Western Union
The Western Union Company is an American multinational financial services company, headquartered in Denver, Colorado. Founded in 1851 as the New York and Mississippi Valley Printing Telegraph Company in Rochester, New York, the company changed its name to the Western Union Telegraph Company in 1856 after merging with several other telegraph companies. The company dominated the American telegraphy industry from the 1860s to the 1980s, pioneering technology such as telex and developing a range of telegraph-related services (including wire money transfer) in addition to its core business of transmitting and delivering telegram messages.

Minelayer
A minelayer is any warship, submarine or military aircraft deploying explosive mines. Since World War I the term "minelayer" refers specifically to a naval ship used for deploying naval mines. "Mine planting" was the term for installing controlled mines at predetermined positions in connection with coastal fortifications or harbor approaches that would be detonated by shore control when a ship was fixed as being within the mine's effective range. Before World War I, mine ships were termed mine planters generally. For example, in an address to the United States Navy ships of Mine Squadron One at Portland, England, Admiral Sims used the term “mine layer” while the introduction speaks of the men assembled from the “mine planters”. During and after that war the term "mine planter" became particularly associated with defensive coastal fortifications. The term "minelayer" was applied to vessels deploying both defensive- and offensive mine barrages and large scale sea mining. " ...
