Long Eddy Point Lighthouse
The Long Eddy Point Lighthouse (also known as The Whistle) is a Canadian lighthouse on Grand Manan Island in the Bay of Fundy. The navigation station was first established in 1874 as a fog alarm only and operated as such until 1966, when the present structure was built incorporating a lighthouse. The building has been designated a heritage lighthouse under Canada's Heritage Lighthouse Protection Act. History In 1874 a steam-powered fog whistle was built at Long Eddy Point, a tree-covered cliff at the northern end of Grand Manan. It began operation on 1 July 1874. It was built half-way up the cliff overlooking the Bay of Fundy, above the high water mark. It emitted 3 blasts, four seconds long, every minute. The station's infrastructure included a keeper's house, a coal shed, storage tanks for the water used to generate the steam for the whistle, and a wharf at the bottom of the cliff for delivering supplies to the keeper. Coal was brought from the top of the cliff by a wooden chut ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grand Manan
Grand Manan is a Canadian island in the Bay of Fundy. Grand Manan is also the name of an incorporated village, which includes the main island and all of its adjacent islands, except White Head Island. It is governed as a village and is part of the province of New Brunswick. The point on the mainland closest to the island is near the town of Lubec, Maine, the easternmost point of the continental United States, across the Grand Manan Channel. Grand Manan is 32 kilometres south of Blacks Harbour, New Brunswick. Toponymy "Manan" is a corruption of ''mun-an-ook'' or ''man-an-ook'', meaning "island place" or "the island", from the Maliseet-Passamaquoddy-Penobscot First Nations who, according to oral history, used Grand Manan and its surrounding islands as a safe place for the elderly Passamaquoddy during winter months and as a sacred burial place (''ook'' means "people of"). In 1606 Samuel de Champlain sheltered on nearby White Head Island and produced a map calling the island "Manth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heritage Lighthouse Protection Act
The ''Heritage Lighthouse Protection Act'' (long title:An Act To Protect Heritage Lighthouses (french: Loi sur la protection des phares patrimoniaux)) is an Act of the Parliament of Canada (designated Bill S-215) for the designation and preservation of historically significant Canadian lighthouses. It was passed by the Canadian Parliament in May 2008. The act set up a public nomination process and sets heritage building conservation standards for lighthouses which are officially designated. First introduced in 2000 as Bill S-21 in the Senate of Canada the bill enjoyed consistent multi-party support despite the unpredictable legislative agendas of minority Parliaments and was repeatedly re-introduced. The final vote of approval was made by the Canadian Senate in 2008 and the bill received Royal Assent on May 29, 2008. The ''Heritage Lighthouse Protection Act'' (S.C. 2008, c. 16) came into effect on May 29, 2010 and established a deadline of May 29, 2012 to nominate lighthouses for ...

Bay Of Fundy
The Bay of Fundy (french: Baie de Fundy) is a bay between the Canadian provinces of New Brunswick and Nova Scotia, with a small portion touching the U.S. state of Maine. It is an arm of the Gulf of Maine. Its extremely high tidal range is the highest in the world. The name is likely a corruption of the French word , meaning 'split'. Hydrology Tides The tidal range in the Bay of Fundy is about ; the average tidal range worldwide is only . Some tides are higher than others, depending on the position of the moon, the sun, and atmospheric conditions. Tides are semidiurnal, meaning they have two highs and two lows each day, with about six hours and 13 minutes between each high and low tide. Because of tidal resonance in the funnel-shaped bay, the tides that flow through the channel are very powerful. In one 12-hour tidal cycle, about 100 billion tons (110 billion short tons) of water flows in and out of the bay, which is twice as much as the combined total flow of all the rive ...

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 ...

High Water Mark
A high water mark is a point that represents the maximum rise of a body of water over land. Such a mark is often the result of a flood, but high water marks may reflect an all-time high, an annual high (highest level to which water rose that year) or the high point for some other division of time. Knowledge of the high water mark for an area is useful in managing the development of that area, particularly in making preparations for flood surges. High water marks from floods have been measured for planning purposes since at least as far back as the civilizations of ancient Egypt. It is a common practice to create a physical marker indicating one or more of the highest water marks for an area, usually with a line at the level to which the water rose, and a notation of the date on which this high water mark was set. This may be a free-standing flood level sign or other marker, or it may be affixed to a building or other structure that was standing at the time of the flood that se ...

Abutments
An abutment is the substructure at the ends of a bridge span or dam supporting its superstructure. Single-span bridges have abutments at each end which provide vertical and lateral support for the span, as well as acting as retaining walls to resist lateral movement of the earthen fill of the bridge approach. Multi-span bridges require piers to support ends of spans unsupported by abutments. Dam abutments are generally the sides of a valley or gorge, but may be artificial in order to support arch dams such as Kurobe Dam in Japan. The civil engineering term may also refer to the structure supporting one side of an arch, or masonry used to resist the lateral forces of a vault.Pevsner, N. (1970) ''Cornwall''; 2nd ed. Harmondsworth: Penguin; p. 245 The impost or abacus of a column in classical architecture may also serve as an abutment to an arch. The word derives from the verb "abut", meaning to "touch by means of a mutual border". Use in engineering An abutment may be us ...

Diaphone
The diaphone is a noisemaking device best known for its use as a foghorn: It can produce deep, powerful tones, able to carry a long distance. Although they have fallen out of favor, diaphones were also used at some fire stations and in other situations where a loud, audible signal was required. History The diaphone horn was based directly on the organ stop of the same name invented by Robert Hope-Jones, creator of the Wurlitzer organ. Hope-Jones' design was based on a piston that was closed only at its bottom end and had slots, perpendicular to its axis, cut through its sides; the slotted piston moved within a similarly slotted cylinder. Outside of the cylinder was a reservoir of high-pressure air. Initially, high-pressure air would be admitted behind the piston, pushing it forward. When the slots of the piston aligned with those of the cylinder, air passed into the piston, making a sound and pushing the piston back to its starting position, whence the cycle would repeat. A ...

Swallowtail Lighthouse
The Swallowtail Lighthouse is a Canadian lighthouse located on Grand Manan Island in the Bay of Fundy. It was the first lighthouse to be built on the island. It was first lit on 7 July 1860 and was automated and de-staffed in 1986. Origin The wreck of the merchant ship ''Lord Ashburton'' in 1857 on the northern tip of Grand Manan, with the loss of 21 lives, led the New Brunswick Legislative Assembly to call for "a Light House to be erected on the Northern Head of Grand Manan". The site chosen was a headland called the "Swallow's Tail" near the entrance to the harbour at North Head. The lighthouse tower and keeper's dwelling were built in 1859 at a cost of £495 and the lantern was first lit on 7 July 1860. It was the first lighthouse to be built on the island of Grand Manan. Infrastructure The light was originally provided by nine lamps and reflectors, which were later increased to ten. In 1887 a lens replaced the lamps and reflectors. In 1907 a fourth-order Fresnel lens was insta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lighthouses In New Brunswick
A lighthouse is a tower, building, or other type of physical structure designed to emit light from a system of lamps and 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 signal for reefs and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
