Comboyuro Point Light
Comboyuro Point Light, which was also known later as Comboyuro Light, was located on Comboyuro Point, at the northwestern tip of Moreton Island. It is one of the Moreton Island lighthouses. History The first navigational aid at the point was a lightroom erected in 1863 with kerosene burners. In 1867 the lightroom was replaced with a wooden tower. A taller wooden tower was erected in 1874 or in 1877, and a condensing apparatus was installed. The old tower was moved to Burnett Heads together with the old apparatus from Cowan Cowan Point Light, and is now known as the Old Burnett Heads Light, while the old apparatus was refurbished and installed at Cleveland Point Light. A 1909 listing describes the tower as a wooden tower, carrying a fixed fourth order dioptric apparatus. The light was showing red and white sectors, and visible for . Due to coastal erosion the tower had to be moved inland twice, in 1890 and another in 1905. In 1906 the lighthouse keeper's cottage, a four bedroo ...

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] |

Moreton Island Lighthouses
Moreton Island is a large sand island on the eastern side of Moreton Bay, on the coast of South East Queensland, Australia. Due to the island's importance in navigating the northern passage into Moreton Bay and Brisbane, at least five lighthouses were constructed on the island, starting with Cape Moreton Light in , the first lighthouse in Queensland, and followed by at least four more lighthouses established from the 1860s, at Comboyuro Point, North Point, Cowan Cowan Point and Yellow Patch. Comboyuro Point Light, Cowan Cowan Point Light and Yellow Patch Light all had to be moved from their original location due to coastal erosion. Of the five lighthouses, only Cape Moreton Light survived and is still active today. Background In 1825, Brisbane was established as a penal settlement. In spite of the hazards, the preferred access to Moreton Bay and Brisbane was through the southern entrance, between Moreton Island and North Stradbroke Island, mainly due to shorter shipping route an ...

Kerosene
Kerosene, paraffin, or lamp oil is a combustible hydrocarbon liquid which is derived from petroleum. It is widely used as a fuel in aviation as well as households. Its name derives from el, κηρός (''keros'') meaning " wax", and was registered as a trademark by Canadian geologist and inventor Abraham Gesner in 1854 before evolving into a generic trademark. It is sometimes spelled kerosine in scientific and industrial usage. The term kerosene is common in much of Argentina, Australia, Canada, India, New Zealand, Nigeria, and the United States, while the term paraffin (or a closely related variant) is used in Chile, eastern Africa, South Africa, Norway, and in the United Kingdom. The term lamp oil, or the equivalent in the local languages, is common in the majority of Asia and the Southeastern United States. Liquid paraffin (called mineral oil in the US) is a more viscous and highly refined product which is used as a laxative. Paraffin wax is a waxy solid extracted from ...

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 ...

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] |
Cleveland Point Light
Cleveland Point Light, also known as Point Cleveland Light, is a lighthouse located on the north-eastern tip of Cleveland Point, at Cleveland, Redland City, Queensland, Australia. It overlooks Moreton Bay to the east and Raby Bay to the west. The old lighthouse was established in 1864-1865 as a wooden hexagonal tower. It is one of only two surviving lighthouses of this form, the other being Old Burnett Heads Light. A newer light, constructed of a concrete post, replaced it in 1976, and the old lighthouse was relocated a short distance away, where it stands today. The newer light was removed in 2009. An early 1847 private beacon was replaced by a temporary government light in 1864, and then the permanent tower in 1865. The lens was upgraded twice, in 1874 and 1879. In 1934 the lighthouse was converted to electricity, and remained so until 1976 when it was deactivated and replaced by a concrete pile light constructed just away. The original tower was moved away in 1979 and r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
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 st ...

Acetylene Gas
Acetylene ( systematic name: ethyne) is the chemical compound with the formula and structure . It is a hydrocarbon and the simplest alkyne. This colorless gas is widely used as a fuel and a chemical building block. It is unstable in its pure form and thus is usually handled as a solution. Pure acetylene is odorless, but commercial grades usually have a marked odor due to impurities such as divinyl sulfide and phosphine.Compressed Gas Association (1995Material Safety and Data Sheet – Acetylene As an alkyne, acetylene is unsaturated because its two carbon atoms are bonded together in a triple bond. The carbon–carbon triple bond places all four atoms in the same straight line, with CCH bond angles of 180°. Discovery Acetylene was discovered in 1836 by Edmund Davy, who identified it as a "new carburet of hydrogen". It was an accidental discovery while attempting to isolate potassium metal. By heating potassium carbonate with carbon at very high temperatures, he pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
