Ona Lighthouse
Ona Lighthouse ( no, Ona fyr) is located on the small island of Ona in Ålesund Municipality in Møre og Romsdal county, Norway. The lighthouse is built on ''Onakalven'', the highest cliff on the island overlooking the harbor and the few, clustered wooden houses on this small island. The original rotating Fresnel lens remains in use. History The lighthouse was built in 1867 and was fully automated in 1971. The tall round cast iron lighthouse is red and the light sits at an elevation of above sea level. The continuous white light shines all night long and it also has a bright red flash every 30 seconds. The main light has an intensity of 79,000 candela and the red flash has an intensity of 295,000 candela. The lighthouse is in operation from 16 July until 21 May each year; it does not operate during the rest of the year due to the midnight sun in May–July. The light can be seen for up to .

Ona, Sandøy
Ona is a village and an island group located in Ålesund Municipality in Møre og Romsdal county, Norway. The tiny island of Ona and the larger island of Husøy are separated by a shallow wide waterway. The two islands are collectively referred to as ''Ona''. The islands are located northwest of the island of Sandøya. The historic village of Ona covers most of the tiny island of Ona. The highest point on Ona, the Onakalven cliff, is the site of the Ona Lighthouse, which was built in 1867. The lighthouse and the tiny island itself has become a well known tourist spot in Western Norway. It has a ferry connection with the other islands in Sandøy and to the island of Gossa in Aukra Municipality. The island has a population of about 40, with a gradually diminishing population for the last 50 years. Ona has been populated for centuries because of the proximity to the fishing grounds further out to the Atlantic Ocean, and fishing has traditionally been the only source of income. ...

Møre Og Romsdal
Møre og Romsdal (; en, Møre and Romsdal) is a county in the northernmost part of Western Norway. It borders the counties of Trøndelag, Innlandet, and Vestland. The county administration is located in the town of Molde, while Ålesund is the largest town. The county is governed by the Møre og Romsdal County Municipality which includes an elected county council and a county mayor. The national government is represented by the county governor. Name The name ''Møre og Romsdal'' was created in 1936. The first element refers to the districts of Nordmøre and Sunnmøre, and the last element refers to Romsdal. Until 1919, the county was called "Romsdalens amt", and from 1919 to 1935 "Møre fylke". For hundreds of years (1660-1919), the region was called ''Romsdalen amt'', after the Romsdalen valley in the present-day Rauma Municipality. The Old Norse form of the name was ''Raumsdalr''. The first element is the genitive case of the name ''Raumr'' derived from the name of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Norway
Norway, officially the Kingdom of Norway, is a Nordic country in Northern Europe, the mainland territory of which comprises the western and northernmost portion of the Scandinavian Peninsula. The remote Arctic island of Jan Mayen and the archipelago of Svalbard also form part of Norway. Bouvet Island, located in the Subantarctic, is a dependency of Norway; it also lays claims to the Antarctic territories of Peter I Island and Queen Maud Land. The capital and largest city in Norway is Oslo. Norway has a total area of and had a population of 5,425,270 in January 2022. The country shares a long eastern border with Sweden at a length of . It is bordered by Finland and Russia to the northeast and the Skagerrak strait to the south, on the other side of which are Denmark and the United Kingdom. Norway has an extensive coastline, facing the North Atlantic Ocean and the Barents Sea. The maritime influence dominates Norway's climate, with mild lowland temperatures on the se ...

Cliff
In geography and geology, a cliff is an area of rock which has a general angle defined by the vertical, or nearly vertical. Cliffs are formed by the processes of weathering and erosion, with the effect of gravity. Cliffs are common on coasts, in mountainous areas, escarpments and along rivers. Cliffs are usually composed of rock that is resistant to weathering and erosion. The sedimentary rocks that are most likely to form cliffs include sandstone, limestone, chalk, and dolomite. Igneous rocks such as granite and basalt also often form cliffs. An escarpment (or scarp) is a type of cliff formed by the movement of a geologic fault, a landslide, or sometimes by rock slides or falling rocks which change the differential erosion of the rock layers. Most cliffs have some form of scree slope at their base. In arid areas or under high cliffs, they are generally exposed jumbles of fallen rock. In areas of higher moisture, a soil slope may obscure the talus. Many cliffs also fea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Harbor
A harbor (American English), harbour (British English; see spelling differences), or haven is a sheltered body of water where ships, boats, and barges can be docked. The term ''harbor'' is often used interchangeably with ''port'', which is a man-made facility built for loading and unloading vessels and dropping off and picking up passengers. Ports usually include one or more harbors. Alexandria Port in Egypt is an example of a port with two harbors. Harbors may be natural or artificial. An artificial harbor can have deliberately constructed breakwaters, sea walls, or jettys or they can be constructed by dredging, which requires maintenance by further periodic dredging. An example of an artificial harbor is Long Beach Harbor, California, United States, which was an array of salt marshes and tidal flats too shallow for modern merchant ships before it was first dredged in the early 20th century. In contrast, a natural harbor is surrounded on several sides of land. Examples o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Candela
The candela ( or ; symbol: cd) is the unit of luminous intensity in the International System of Units (SI). It measures luminous power per unit solid angle emitted by a light source in a particular direction. Luminous intensity is analogous to radiant intensity, but instead of simply adding up the contributions of every wavelength of light in the source's spectrum, the contribution of each wavelength is weighted by the standard luminosity function (a model of the sensitivity of the human eye to different wavelengths). A common wax candle emits light with a luminous intensity of roughly one candela. If emission in some directions is blocked by an opaque barrier, the emission would still be approximately one candela in the directions that are not obscured. The word ''candela'' is Latin for ''candle''. The old name "candle" is still sometimes used, as in ''foot-candle'' and the modern definition of ''candlepower''.

Midnight Sun
The midnight sun is a natural phenomenon that occurs in the summer months in places north of the Arctic Circle or south of the Antarctic Circle, when the Sun remains visible at the local midnight. When the midnight sun is seen in the Arctic, the Sun appears to move from left to right, but in Antarctica the equivalent apparent motion is from right to left. This occurs at latitudes from 65°44' to 90° north or south, and does not stop exactly at the Arctic Circle or the Antarctic Circle, due to refraction. The opposite phenomenon, polar night, occurs in winter, when the Sun stays below the horizon throughout the day. Details Around the summer solstice (approximately 21 June in the Northern Hemisphere and 21 December in the Southern Hemisphere), in certain areas the Sun does not set below the horizon within a 24-hour period. Geography Because there are no permanent human settlements south of the Antarctic Circle, apart from research stations, the countries and territo ...

Lighthouses In Norway
The coast of Norway is 100,915 km long and there have been a total of 212 lighthouses along it, but no more than 154 have ever been operational at the same time. The first, Lindesnes Lighthouse, opened in 1655; the newest Lighthouse, Anda, was finished in 1932. The first Lighthouses were private operations, but in 1821 the government made the Channel and Harbor Inspector responsible for Lighthouses in Norway. A dedicated Lighthouse Administration was set up in 1841. The Lighthouses are today mostly automated and since 1974, run by the Norwegian Coastal Administration. Two lightvessels had been operated along the Norwegian coast. "Enigheden" off Ålesund from 1856 vas replaced with Lepsøyrev Lighthouse in 1879, and "Ildjernsflu" moored off Nesodden from 1914 until it was scrapped in 1968. This list, while not complete, is sorted by location along the shipping lane from the border with Sweden in the south to Russia in the northeast. The Norwegian Coastal Administration main ...

Lighthouses Completed In 1867
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] |
