Head Harbour Lighthouse
Head Harbour Lighthouse, also known as East Quoddy Head Light (mostly by Americans to differentiate the Canadian beacon from its American counterpart, West Quoddy Head Light) is a lighthouse and station on Campobello Island, New Brunswick. Erected in 1829 by the provincial government, its purpose was to aid navigation for ships in the Bay of Fundy. While West Quoddy Light stands at the mouth of the narrows around Lubec, Maine, East Quoddy was built on the north side of Campobello, on a small tidal islet connected to the primary landmass, guiding entry into Passamaquoddy Bay. Today, the light and its accessory structures are a historically designated heritage site, supported by an independent preservation group. Description The lighthouse is a octagonal tower of heavy timber; the structure is painted a highly-visible white and marked with a large red St. George's Cross which has been a landmark dating back to the Canadian Confederation.

West Quoddy Head Light
West Quoddy Head, in Quoddy Head State Park, Lubec, Maine, is the easternmost point of the contiguous United States. In 1808 a lighthouse was constructed at the site to guide ships through the Quoddy Narrows. The current tower, with distinctive red-and-white stripes, was constructed in 1858 and is an active aid to navigation. The 3rd order Fresnel lens is the only 3rd order and one of only eight Fresnel lenses still in use on the Maine Coast. The light station was added to the National Register of Historic Places as West Quoddy Head Light Station on July 4, 1980. Description West Quoddy Head is an easterly-pointing peninsula in southeastern Lubec, overlooking Quoddy Narrows, a strait between Lubec and Campobello Island, Canada, that provides access to Passamaquoddy Bay and harbors located on the St. Croix River and other rivers which empty into the bay. Most of the peninsula is part of Quoddy Head State Park, and the light station is located near the southern end of its eastern ...

Lighthouse Off Campobello Island (NB) September 2017 (38834375355)
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] |

Lighthouses In Maine
This is a list of all lighthouses in the U.S. state of Maine as identified by the United States Coast Guard. There are fifty-seven active lights in the state, two of which are maintained as private aids; nine are standing but inactive, and three have been destroyed, one of which has been replaced by a skeleton tower. This includes two stations which originally featured twin towers; in both cases both towers survive but only one of each pair is active. The Portland Head Light, first lit in 1791, is the oldest light in the state and was the first US lighthouse completed after independence from Britain. The last lighthouse in the state, the second Whitlocks Mill Light, was first lit in 1910; it is also the most northerly light in the state and therefore on the US Atlantic Coast. The West Quoddy Head Light sits on the easternmost point of the continental United States. The tallest tower is that of Boon Island Light at , though the Seguin Light focal plane, at , is the highest in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Canadian Coast Guard
The Canadian Coast Guard (CCG; french: links=no, Garde côtière canadienne, GCC) is the coast guard of Canada. Formed in 1962, the coast guard is tasked with marine search and rescue (SAR), communication, navigation, and transportation issues in Canadian waters, such as navigation aids and icebreaking, marine pollution response, and support for other Canadian government initiatives. The coast guard operates 119 vessels of varying sizes and 23 helicopters, along with a variety of smaller craft. The CCG is headquartered in Ottawa, Ontario, and is a special operating agency within Fisheries and Oceans Canada (Department of Fisheries and Oceans). Role and responsibility Unlike armed coast guards of some other nations, the CCG is a government marine organization without naval or law enforcement responsibilities. Naval operations in Canada's maritime environment are exclusively the responsibility of the Royal Canadian Navy. Enforcement of Canada's maritime-related federal statutes ma ...

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 ...

Fresnel Lens
A Fresnel lens ( ; ; or ) is a type of composite compact lens developed by the French physicist Augustin-Jean Fresnel (1788–1827) for use in lighthouses. It has been called "the invention that saved a million ships." The design allows the construction of lenses of large aperture and short focal length without the mass and volume of material that would be required by a lens of conventional design. A Fresnel lens can be made much thinner than a comparable conventional lens, in some cases taking the form of a flat sheet. The simpler dioptric (purely refractive) form of the lens was first proposed by Count Buffon and independently reinvented by Fresnel. The ''catadioptric'' form of the lens, entirely invented by Fresnel, has outer elements that use total internal reflection as well as refraction; it can capture more oblique light from a light source and add it to the beam of a lighthouse, making the light visible from greater distances.

Ferry
A ferry is a ship, watercraft or amphibious vehicle used to carry passengers, and sometimes vehicles and cargo, across a body of water. A passenger ferry with many stops, such as in Venice, Italy, is sometimes called a water bus or water taxi. Ferries form a part of the public transport systems of many waterside cities and islands, allowing direct transit between points at a capital cost much lower than bridges or tunnels. Ship connections of much larger distances (such as over long distances in water bodies like the Mediterranean Sea) may also be called ferry services, and many carry vehicles. History In ancient times The profession of the ferryman is embodied in Greek mythology in Charon, the boatman who transported souls across the River Styx to the Underworld. Speculation that a pair of oxen propelled a ship having a water wheel can be found in 4th century Roman literature "''Anonymus De Rebus Bellicis''". Though impractical, there is no reason why it could not work ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tides
Tides are the rise and fall of sea levels caused by the combined effects of the gravitational forces exerted by the Moon (and to a much lesser extent, the Sun) and are also caused by the Earth and Moon orbiting one another. Tide tables can be used for any given locale to find the predicted times and amplitude (or "tidal range"). The predictions are influenced by many factors including the alignment of the Sun and Moon, the phase and amplitude of the tide (pattern of tides in the deep ocean), the amphidromic systems of the oceans, and the shape of the coastline and near-shore bathymetry (see '' Timing''). They are however only predictions, the actual time and height of the tide is affected by wind and atmospheric pressure. Many shorelines experience semi-diurnal tides—two nearly equal high and low tides each day. Other locations have a diurnal tide—one high and low tide each day. A "mixed tide"—two uneven magnitude tides a day—is a third regular category. Tides va ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
