Dyrhólaey Lighthouse
The Dyrhólaey Lighthouse ( ) is a lighthouse located on the central south coast of Iceland. Description The lighthouse consists of a square concrete tower, painted white with red trim. Integral keepers quarters are placed on the left and right sides of the tower. A red metal lantern house is placed on top of the tower. The focal plane of the light is . The overall height of the tower is . The site (but not the tower) is open to visitors. History The light station at Dyrhólaey was established in 1910. The first lighthouse was a skeletal steel tower prefabricated in Sweden. The present lighthouse was built in 1927. Characteristic The light flashes white every 10 seconds. It marks the southernmost point of the mainland of Iceland. See also * List of lighthouses in Iceland This is a list of lighthouses in Iceland.

Vík í Mýrdal
The village of Vík (; or Vík í Mýrdal in full) is the southernmost village in Iceland, located on the main ring road around the island, around by road southeast of Reykjavík. Despite its small size (750 inhabitants in Mýrdalshreppur as of January 2021) it is the largest settlement for some around and is an important staging post, and thus it is indicated on road signs from a long distance away. It is an important service center for the inhabitants of and visitors to the coastal strip between Skógar and the west edge of the Mýrdalssandur glacial outwash plain. Overview In 1991, the US journal ''Islands Magazine'' counted the beach at Vík as one of the ten most beautiful beaches on Earth. Its stretch of black basalt sand is one of the wettest places in Iceland. The cliffs west of the beach are home to many seabirds, most notably puffins which burrow into the shallow soils during the nesting season. Offshore lie stacks of basalt rock, remnants of a once more extensive ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lighthouse
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] |
Iceland
Iceland ( is, Ísland; ) is a Nordic island country in the North Atlantic Ocean and in the Arctic Ocean. Iceland is the most sparsely populated country in Europe. Iceland's capital and largest city is Reykjavík, which (along with its surrounding areas) is home to over 65% of the population. Iceland is the biggest part of the Mid-Atlantic Ridge that rises above sea level, and its central volcanic plateau is erupting almost constantly. The interior consists of a plateau characterised by sand and lava fields, mountains, and glaciers, and many glacial rivers flow to the sea through the lowlands. Iceland is warmed by the Gulf Stream and has a temperate climate, despite a high latitude just outside the Arctic Circle. Its high latitude and marine influence keep summers chilly, and most of its islands have a polar climate. According to the ancient manuscript , the settlement of Iceland began in 874 AD when the Norwegian chieftain Ingólfr Arnarson became the first p ...

Lighthouse Keeper
A lighthouse keeper or lightkeeper is a person responsible for tending and caring for a lighthouse, particularly the light and lens in the days when oil lamps and clockwork mechanisms were used. Lighthouse keepers were sometimes referred to as "wickies" because of their job trimming the wicks. Duties and functions Historically, lighthouse keepers were needed to trim the wicks, replenish fuel, wind clockworks and perform maintenance tasks such as cleaning lenses and windows. They were also responsible for the fog signal and the weather station, and played a major role in search and rescue at sea. Because most lighthouses are located in remote, isolated or inaccessible areas on islands and coastlines, it was typical for the work of lighthouse keeper to remain within a family, passing from parents to child, all of whom lived in or near the lighthouse itself. "Stag light" was an unofficial term given to some isolated lighthouses in the United States Lighthouse Service. It meant sta ...

Focal Plane
In Gaussian optics, the cardinal points consist of three pairs of points located on the optical axis of a rotationally symmetric, focal, optical system. These are the '' focal points'', the principal points, and the nodal points. For ''ideal'' systems, the basic imaging properties such as image size, location, and orientation are completely determined by the locations of the cardinal points; in fact only four points are necessary: the focal points and either the principal or nodal points. The only ideal system that has been achieved in practice is the plane mirror, however the cardinal points are widely used to ''approximate'' the behavior of real optical systems. Cardinal points provide a way to analytically simplify a system with many components, allowing the imaging characteristics of the system to be approximately determined with simple calculations. Explanation The cardinal points lie on the optical axis of the optical system. Each point is defined by the effect the opti ...

Dyrhólaey
Dyrhólaey (, "door hill island"), formerly known by seamen as Cape Portland, is a small promontory located on the south coast of Iceland, not far from the village Vík. It was formerly an island of volcanic origin, which is also known by the Icelandic word ''eyja'' meaning ''island''. The volcano erupted about 100 thousand years ago during the Pleistocene. The peninsula has an elevation of , and the Dyrhólaey Lighthouse sits at the top of the formation facing the sea. The view from Dyrhólaey is broad: To the north is to be seen the big glacier Mýrdalsjökull. To the east, the black lava columns of the Reynisdrangar come out of the sea, and to the west the whole coastline in the direction of Selfoss is visible – depending on weather conditions. In front of the peninsula, there is a gigantic black arch of lava standing in the sea, which gave the peninsula its name (meaning: ''door hill island''). In the summertime, many Atlantic puffins can be found nesting on the cli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
