Point Lookout Light, Australia
Point Lookout Light is an active lighthouse on Point Lookout, a headland on North Stradbroke Island, Queensland, Australia. History A proposal for a lighthouse and a signal station on Point Lookout were made as early as 1825. A pilot station was built in 1825 elsewhere on the island, on Amity Point, lighting the South Passage into Moreton Bay. In 1848 this pilot station was also moved. A lighthouse on Point Lookout was finally constructed in 1932, the first settlement at the point. The light source was a carbide lamp operated by acetylene gas, and a hut for storage of the gas cylinders was built at the close by beach, which was to be named Cylinder Beach for this reason. Structure and display The lighthouse is high, made of concrete and painted white. The current display is three white flashes every 15 seconds (Fl.(3)W. 15s).

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] |
Headland
A headland, also known as a head, is a coastal landform, a point of land usually high and often with a sheer drop, that extends into a body of water. It is a type of promontory. A headland of considerable size often is called a cape.Whittow, John (1984). ''Dictionary of Physical Geography''. London: Penguin, 1984, pp. 80, 246. . Headlands are characterised by high, breaking waves, rocky shores, intense erosion, and steep sea cliff. Headlands and bays are often found on the same coastline. A bay is flanked by land on three sides, whereas a headland is flanked by water on three sides. Headlands and bays form on discordant coastlines, where bands of rock of alternating resistance run perpendicular to the coast. Bays form when weak (less resistant) rocks (such as sands and clays) are eroded, leaving bands of stronger (more resistant) rocks (such as chalk, limestone, and granite) forming a headland, or peninsula. Through the deposition of sediment within the bay and the erosion of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North Stradbroke Island
North Stradbroke Island ( Jandai: ''Minjerribah''), colloquially ''Straddie'' or ''North Straddie'', is an island that lies within Moreton Bay in the Australian state of Queensland, southeast of the centre of Brisbane. Originally there was only one Stradbroke Island but in 1896 it split into North Stradbroke Island and South Stradbroke Island separated by the Jumpinpin Channel. The Quandamooka people are the traditional owners of North Stradbroke island. The island is divided into four localities: Dunwich, Amity and Point Lookout are small localities centred on the towns of the same name, while the remainder of the island is in the locality of North Stradbroke Island. All the localities are within the City of Redland. At , it is the second largest sand island in the world. On the island there are three small towns, a number of lakes and beaches along most of the seaward coastline with rocky outcrops at Point Lookout. An Aboriginal presence on the island has been long and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Amity Point, Queensland
Amity is a rural town and locality in the City of Redland, Queensland, Australia. In the , the locality of Amity had a population of 387 people. It is known as ''Pulan Pulan'' by the traditional owners, the Quandamooka people. Geography Amity is located on the north western point of North Stradbroke Island (known as Amity Point). Directly north is the South Passage and the southern tip of Moreton Island. To the east lies the small town of Point Lookout and to the south lies the main town of North Stradbroke Island, Dunwich. Wallum Creek snakes along the southern border of the town. Rainbow Channel lies directly adjacent to Amity Point in Moreton Bay. History In 1824 John Oxley named the headland Amity Point after the brig ''Amity'' he sailed in when establishing the Moreton Bay penal colony. It had been given the name Cypress Point for which it was only known as for a brief period. The site was chosen as a pilot station by John Gray because of its location close to the South ...

South Passage (Queensland)
South Passage is channel between the South Pacific Ocean and Moreton Bay. The other entrances to the bay are the North Passage or North Entrance and Jumpinpin Channel in the south. It was once the main entrance for ships entering the bay. South Passage begins in the shallow sand-barred channel between Moreton Island and North Stradbroke Island and continues along North Stradbroke Island past Amity Point to Dunwich. The bay inside of South Passage consists of shallow water sandbanks. Crossing the channel by small boat is not recommended, especially during a high swell, due to the network of channels and shifting sand bars. The tidal flow is rapid with a rate of 150 cm per second during the flooding tide and slightly slower during the ebb tide of 100 cm per second. The passage has a return coefficient of 50%, meaning that half the amount of water that leaves the bay via the passage returns the same way on the flooding tide. History The channel was not noticed by Lieut ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moreton Bay
Moreton Bay is a bay located on the eastern coast of Australia from central Brisbane, Queensland. It is one of Queensland's most important coastal resources. The waters of Moreton Bay are a popular destination for recreational anglers and are used by commercial operators who provide seafood to market. The Port of Brisbane coordinates large traffic along the shipping channel which crosses the northern section of the bay. The bay serves as a safe approach to the airport and reduces noise pollution over the city to the west of the runway. A number of barge, ferry and water-taxi services also travel over the bay. Moreton Bay was the site of conflict between the Quandamooka people and early European settlers. It contains environmentally significant habitats and large areas of sandbanks. The bay is the only place in Australia where dugong gather into herds. Many parts of the mainland foreshore and southern islands are settled. The waters of Moreton Bay are relatively calm, being s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carbide Lamp
Carbide lamps, or acetylene gas lamps, are simple lamps that produce and burn acetylene (C2H2) which is created by the reaction of calcium carbide (CaC2) with water (H2O). Acetylene gas lamps were used to illuminate buildings, as lighthouse beacons, and as headlights on motor-cars and bicycles. Portable acetylene gas lamps, worn on the hat or carried by hand, were widely used in mining in the early twentieth century. They are still employed by cavers, hunters, and cataphiles. Small carbide lamps called "carbide candles" or "smokers" are used for blackening rifle sights to reduce glare. They are sometimes referred to as "smokers" because of the sooty flame produced by acetylene. Mechanism A mining or caving lamp has calcium carbide placed in a lower chamber, the generator. The upper reservoir is then filled with water. A threaded valve or other mechanism is used to control the rate at which the water is allowed to drip into the chamber containing the calcium carbide.

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 produced a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
