Cowan Cowan Point Light
Cowan Cowan Point Light, was also known as Cowan Cowan Light or Cowan Point Light, was located on Cowan Cowan Point, on the western shore of Moreton Island, Queensland, Australia. History The first settlement at the point was a pilot station, moved from Amity Point in August 1848. The pilot station was later moved to Bulwer. The first lighthouse was constructed in the early 1860s, a wooden tower. It carried a large kerosene burner with a reflector and showed a fixed white light. In 1867, together with the construction of the Comboyuro Point Light tower, the tower was extended to . In 1873 it was decided that the tower should be upgraded again. The new lighthouse was constructed in 1874 by the brothers John and Jacob Rooney of Maryborough, who already constructed Sandy Cape Light in 1870. The Rooney brother also constructed Lady Elliot Island Light around the same time, and the same lantern plan was used for both lighthouses. They later constructed Cape Bowling Green Light ...

Moreton Island
Moreton Island (Mulgumpin) is an island on the eastern side of Moreton Bay on the coast of South East Queensland, Australia. The Coral Sea lies on the east coast of the island. Moreton Island lies northeast of the Queensland capital, Brisbane. 95% of the island is contained within a national park and a popular destination for day trippers, four wheel driving, camping, recreational angling and whale watching and a 75-minute ferry ride from Brisbane. It is the third largest sand island in the world. Together with Fraser Island, Moreton Island forms the largest sand structure in the world. It was the traditional country of the Ngugi before the onset of colonization. The island is within the City of Brisbane and is gazetted into four localities, the small townships of Bulwer (on the north-west coast), Cowan Cowan (on the west coast) and Kooringal (on the south-west coast) with the bulk of the island being the locality of Moreton Island. The private Tangalooma Island Resort is a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Burnett Heads
Burnett Heads is a coastal town and locality in the Bundaberg Region, Queensland, Australia. In the , the locality of Burnett Heads had a population of 2,656 people. Geography The locality of Burnett Heads is on the southern side of the Burnett River at its mouth into the Coral Sea.The river forms the western and northern boundaries, while the ocean forms most of the eastern boundary. The land use is a mixture of residential (mostly with proximity to the coast), industrial (mostly the Port of Bundaberg) and some agricultural use (growing sugarcane). There is a network of cane tramways to transport the harvested sugarcane to the Millaquin sugar mill for processing. History Burnett Heads Provisional School opened on 3 April 1878. On 17 September 1888, it became Burnett Heads State School. In February 1883, land surveyed by Charlton and Gardiner, licensed surveyors, in the township of New Bundaberg was offered for sale in the Victoria Hall, Bundaberg. The locality map advertisi ...

Lighthouses In Queensland
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] |

List Of Lighthouses In Australia
This is a list of lighthouses and lightvessels in Australia. Australia has a coastline of , with over 350 lighthouses and navigational aids around the Australian coastline, and a single inland lighthouse, the Point Malcolm lighthouse. The first lighthouse was Macquarie Lighthouse, which was lit in 1793 as a tripod mounted wood and coal fired beacon. The last staffed lighthouse was Maatsuyker Island Lighthouse, off the south coast of Tasmania, which was automated in 1996. Listing The lighthouses and lightvessels of Australia are listed in the National Geospatial-Intelligence Agency ''List of Lights'' publication 111. They are listed by the United Kingdom Hydrographic Office on volume K of the ''Admiralty List of Lights & Fog Signals''. The '' ARLHS World List of Lights'' lists them with the prefix "AUS".

Daymark
A daymark is a navigational aid for sailors and pilots, distinctively marked to maximize its visibility in daylight. The word is also used in a more specific, technical sense to refer to a signboard or daytime identifier that is attached to a day beacon or other aid to navigation. In that sense, a daymark conveys to the mariner during daylight hours the same significance as does the aid's light or reflector at night. Standard signboard shapes are square, triangular and rectangular; and the standard colours are red, green, orange, yellow and black. Notable daymarks * Trinity House Obelisk * Kingswear Daymark * Tasku beacon tower * Keskiniemi beacon tower * Hiidenniemi beacon tower * Laitakari beacon tower * Herring Tower, Langness * Le Hocq * La Tour Cârrée * Scharhörnbake Symbols used on US charts Chart symbols used by the US National Oceanic and Atmospheric Administration Department, 2013.

Dioptric
Dioptrics is the branch of optics dealing with refraction, similarly the branch dealing with mirrors is known as catoptrics. Dioptrics is the study of the refraction of light, especially by lenses. Telescopes that create their image with an objective that is a convex lens ( refractors) are said to be "dioptric" telescopes. An early study of dioptrics was conducted by Ptolemy in relationship to the human eye as well as refraction in media such as water. The understanding of the principles of dioptrics was further expanded by Alhazen, considered the father of modern optics.

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 co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Old Burnett Heads Light
The Old Burnett Heads Light is an inactive lighthouse which used to be located on the south side of the Burnett River entrance, in Burnett Heads, Queensland, Australia. It was relocated to the Burnett Heads Lighthouse Holiday Park. It is one of only two lighthouse surviving to be constructed of timber frame clad with weatherboards, the other being the original Cleveland Point Light. History In the early 1870s Comboyuro Point Light and Cowan Cowan Point Light, two of the lighthouses on Moreton Island were upgraded. A higher tower with a better apparatus was constructed for Comboyuro Point and an improved apparatus was constructed for Cowan Cowan Point. The old apparatus from Comboyuro Point was installed at Cleveland Point Light. The apparatus from Cowan Cowan Point was installed at the old tower from Comboyuro Point, and the tower was installed at the entrance to Burnett River.. Note that says the tower itself was from Cowan Cowan Point. The date of this installation is gi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Booby Island Light
Booby Island Light is an active heritage-listed lighthouse located on Booby Island in the Shire of Torres, near the tip of Cape York Peninsula, west of Prince of Wales Island, within the Endeavour Strait, Queensland, Australia. It marks the western entrance to the navigation channel through the Torres Strait. It was the last of the major lights to be constructed along the Queensland coast. History The colony of Queensland was formed in 1859. In 1862, the Queensland government appointed the first Portmaster, Commander George Poynter Heath. During the following years, several committees were held, but none of them recommended the erection of a lighthouse on Booby Island. It was Heath who first recommended the construction of such a lighthouse, at the Intercolonial Conference of Marine Departments in 1873, where a first order light was finally recommended by the delegates. However, this recommendation was not followed through, and it was only in August 1885 that Heath referred t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
