Grand Harbour Lighthouse
The Grand Harbour Lighthouse was a Canadian lighthouse marking the entrance to Grand Harbour, Grand Manan, New Brunswick. It was built and first lit in 1879 and was decommissioned in 1963. It was severely damaged in the Groundhog Day gale of 1976 and destroyed by a gale in November 2013. The lighthouse was built in 1879 at Fish Fluke Point on Ross Island, a tidal island that forms the eastern shore of Grand Harbour on Grand Manan island in the 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 hi .... Construction cost $1,050, in addition to $150 for the land on which it was built. The square wooden tower had an attached dwelling for the light keeper's family. The lighthouse was equipped with a catoptric lens and was lit for the first time on 10 October 1879. The fixed wh ...

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] |
Groundhog Day Gale Of 1976
The Groundhog Day gale was a severe winter storm that hit the Northeastern United States and southeastern Canada on February 2 (Groundhog Day), 1976. Meteorologist synopsis An upper-level low was stationary across the Desert Southwest of the United States, on January 28. A system in the northern branch of the Westerlies known as a Saskatchewan Screamer, similar to an Alberta clipper but originating as a frontal wave in the next Canadian province to the east, moved east-southeast across Canada beginning on January 30, luring the system in the United States eastward. The cyclones merged by February 2, becoming a significant storm over New England before lifting northward through Quebec into the Davis Strait. At this time, maximum sustained winds reached 164 kilometers per hour (102 mph) in coastal areas (equal to a Category 2 hurricane on the Saffir-Simpson hurricane scale), with wind gusts of up to 188 kilometers per hour (116 mph). By February 6, this e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gale
A gale is a strong wind; the word is typically used as a descriptor in nautical contexts. The U.S. National Weather Service defines a gale as sustained surface winds moving at a speed of between 34 and 47 knots (, or ).National Weather Service Glossary s.v "gale" Forecasters typically issue s when winds of this strength are expected. In the , a gale warning is specifically a maritime warning; the land-based equivalent in N ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tidal Island
A tidal island is a piece of land that is connected to the mainland by a natural or man-made causeway that is exposed at low tide and submerged at high tide. Because of the mystique surrounding tidal islands, many of them have been sites of religious worship, such as Mont-Saint-Michel with its Benedictine Abbey. Tidal islands are also commonly the sites of fortresses because of their natural fortifications.

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 ...

Catoptrics
Catoptrics (from grc-gre, κατοπτρικός ''katoptrikós'', "specular", from grc-gre, κάτοπτρον ''katoptron'' "mirror") deals with the phenomena of reflected light and image-forming optical systems using mirrors. A catoptric system is also called a ''catopter'' (''catoptre''). Ancient texts ''Catoptrics'' is the title of two texts from ancient Greece: *The Pseudo-Euclidean ''Catoptrics''. This book is attributed to Euclid, although the contents are a mixture of work dating from Euclid's time together with work which dates to the Roman period., accessed 31 January 2013 It has been argued that the book may have been compiled by the 4th century mathematician Theon of Alexandria. The book covers the mathematical theory of mirrors, particularly the images formed by plane and spherical concave mirrors. *Hero's ''Catoptrics''. Written by Hero of Alexandria, this work concerns the practical application of mirrors for visual effects. In the Middle Ages, this work was fal ...

Breakwater (structure)
A breakwater is a permanent structure constructed at a coastal area to protect against tides, currents, waves, and storm surges. Part of a coastal management system, breakwaters are installed to minimize erosion, and to protect anchorages, helping isolate vessels within them from marine hazards such as prop washes and wind-driven waves. A breakwater, also known in some contexts as a jetty, may be connected to land or freestanding, and may contain a walkway or road for vehicle access. On beaches where longshore drift threatens the erosion of beach material, smaller structures on the beach, usually perpendicular to the water's edge, may be installed. Their action on waves and current is intended to slow the longshore drift and discourage mobilisation of beach material. In this usage they are more usually referred to as groynes. Purposes Breakwaters reduce the intensity of wave action in inshore waters and thereby provide safe harbourage. Breakwaters may also be small structu ...

Lighthouse Digest
''Lighthouse Digest'', a specialty magazine from FogHorn Publishing in East Machias, Maine, is about maritime history with particular attention to the preservation of lighthouses and their past. Though it is geared toward enthusiasts and antiquarians in the United States, it is also quoted commonly in more academic publications, and its editors have become a staple presence in scholarly circles. Editor Tim Harrison issued the first number in May, 1992. Scope Coverage includes historic and current lighthouse events and an events calendar for lighthouse activities around the United States and elsewhere. They publish a "Doomsday List" of Endangered lighthouses, and have helped save a number of at-risk lighthouses. They have been credited with uncovering many parts of lighthouse history that had been unknown, or which were thought to have been lost. Each issue carries articles and unusual lighthouse-related stories that, for the most part, cannot be found elsewhere, and many phot ...

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] |
