Grandique Point Lighthouse
Grandique Point Lighthouse (also known as 'Grandique Ferry Lighthouse') is an aid to navigation for Lennox Passage, which is the channel of water between the southern shore of Cape Breton Island and Isle Madame, Nova Scotia, Canada. The lighthouse is located on the beach at Grandique Point in Lennox Passage Provincial Park and is accessible by a gravel road within the provincial park. The site is open to the public, the tower is closed. The first light The first Grandique Point Light, a pole light, was established at Grand Dique Beach in 1884 (the spelling 'Grandique' didn't become official until 1956). After the opening of the St. Peters Canal, Lennox Passage saw an increase in marine traffic. For safety reasons, lights were established along the route. The first lightkeeper at Grand Dique was Daniel Clough, appointed at $54 per year. Daniel Clough was the son of the merchant Nathaniel Cough, a recipient of one of the first Crown Land grants on Isle Madame. This first light ...

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. Description The Fresnel lens redu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lighthouses In Nova Scotia
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 a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Coastal Erosion
Coastal erosion is the loss or displacement of land, or the long-term removal of sediment and rocks along the coastline due to the action of waves, currents, tides, wind-driven water, waterborne ice, or other impacts of storms. The landward retreat of the shoreline can be measured and described over a temporal scale of tides, seasons, and other short-term cyclic processes. Coastal erosion may be caused by hydraulic action, abrasion, impact and corrosion by wind and water, and other forces, natural or unnatural. On non-rocky coasts, coastal erosion results in rock formations in areas where the coastline contains rock layers or fracture zones with varying resistance to erosion. Softer areas become eroded much faster than harder ones, which typically result in landforms such as tunnels, bridges, columns, and pillars. Over time the coast generally evens out. The softer areas fill up with sediment eroded from hard areas, and rock formations are eroded away. Also erosion commonly ...

Isle Madame
Isle Madame is an island off southeastern Cape Breton Island in Nova Scotia. It is part of the Municipality of the County of Richmond. Once part of the French colony of Île-Royale, it may have been named for Françoise d'Aubigné, marquise de Maintenon. After the fall of Louisbourg in 1758, 4,000 inhabitants were deported. However, a group of 10 Acadian families from Port Toulouse fled to this Isle Madame where their descendants still live today. It is separated from Cape Breton Island by the Lennox Passage, but connected by a causeway. The island is also connected by bridge to Petit-de-Grat Island, and by causeway and bridge to Janvrin Island. Since 1994, the island has been served by a community television station, CIMC-TV, also known as Telile. Isle Madame is home to approximately 4,300 residents located mostly in the island's communities of Arichat Arichat is an unincorporated place in the Municipality of the County of Richmond, Nova Scotia, Canada.

Canada
Canada is a country in North America. Its ten provinces and three territories extend from the Atlantic Ocean to the Pacific Ocean and northward into the Arctic Ocean, covering over , making it the world's second-largest country by total area. Its southern and western border with the United States, stretching , is the world's longest binational land border. Canada's capital is Ottawa, and its three largest metropolitan areas are Toronto, Montreal, and Vancouver. Indigenous peoples have continuously inhabited what is now Canada for thousands of years. Beginning in the 16th century, British and French expeditions explored and later settled along the Atlantic coast. As a consequence of various armed conflicts, France ceded nearly all of its colonies in North America in 1763. In 1867, with the union of three British North American colonies through Confederation, Canada was formed as a federal dominion of four provinces. This began an accretion of provinces an ...
