Browse Island
Browse Island is a small, approximately , uninhabited island lying in the Timor Sea about north-west of the Kimberley coast of north-western Australia. It is a Western Australian Nature Reserve that is classed as 'Not Class A' vested with the state Conservation Commission and managed by the Department of Environment and Conservation. It is considered Western Australia's most remote island, and is also one of the most remote Australian islands to not fall under external territory status. Environment Fauna The island is an important nesting site for green turtles as well as seabirds. Introduced house mice are present. It is surrounded by extensive coral reefs. The waters around the island are a site of upwelling associated with concentrations of tropical krill, and there have been unconfirmed reports of humpback whales feeding there. Human impact The island was mined for guano from 1870 to 1890. There are nine historic shipwrecks around the island, including one which is li ...

International Space Station
The International Space Station (ISS) is the largest modular space station currently in low Earth orbit. It is a multinational collaborative project involving five participating space agencies: NASA (United States), Roscosmos (Russia), JAXA (Japan), ESA (Europe), and CSA (Canada). The ownership and use of the space station is established by intergovernmental treaties and agreements. The station serves as a microgravity and space environment research laboratory in which scientific research is conducted in astrobiology, astronomy, meteorology, physics, and other fields. The ISS is suited for testing the spacecraft systems and equipment required for possible future long-duration missions to the Moon and Mars. The ISS programme evolved from the Space Station ''Freedom'', a 1984 American proposal to construct a permanently crewed Earth-orbiting station, and the contemporaneous Soviet/Russian '' Mir-2'' proposal from 1976 with similar aims. The ISS is the ninth space station to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guano
Guano (Spanish from qu, wanu) is the accumulated excrement of seabirds or bats. As a manure, guano is a highly effective fertilizer due to the high content of nitrogen, phosphate, and potassium, all key nutrients essential for plant growth. Guano was also, to a lesser extent, sought for the production of gunpowder and other explosive materials. The 19th-century seabird guano trade played a pivotal role in the development of modern input-intensive farming. The demand for guano spurred the human colonization of remote bird islands in many parts of the world. Unsustainable seabird guano mining processes can result in permanent habitat destruction and the loss of millions of seabirds. Bat guano is found in caves throughout the world. Many cave ecosystems are wholly dependent on bats to provide nutrients via their guano which supports bacteria, fungi, invertebrates, and vertebrates. The loss of bats from a cave can result in the extinction of species that rely on their guano. U ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Islands Of The Kimberley (Western Australia)
The Islands of the Kimberley are a group of over 2,500 islands lying off the coast of the Kimberley region of Western Australia. The islands extend from the Western Australia–Northern Territory border in the east to just north of Broome in the west. North-West Kimberley Islands 1970s survey In 1971, 1972, 1973 a series of biological surveys were carried out. 1971 visit The list is in the order of visits in August 1971. * Middle Osborn * Fenelon * Borda * South West Osborn * Low rocks * Sir Graham Moore * Louis * North Eclipse * Augustus * Darcy * Champagny * Uwins * Commerson * Coronation * Bigge Kimberley Islands Biological Survey A biological survey of 22 of the islands was conducted between December 2006 and December 2010 by the Department of Environment and Conservation, traditional owners, the Australian Museum and the Western Australian Museum.

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 reef ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acetylene
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 produce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Navy
The United States Navy (USN) is the maritime service branch of the United States Armed Forces and one of the eight uniformed services of the United States.

World War 2
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, massa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MOU Box
The MOU Box, or sometimes the MOU 74 Box, refers to a rectangular tract of marine waters in the Timor Sea, lying within Australia's Exclusive Economic Zone, that is subject to a 1974 memorandum of understanding (MoU), and subsequent agreements, between Australia and Indonesia rated to traditional fishing rights consistent with UNDRIP. The MOU Box covers an area of about including Scott and Seringapatam Reefs, Browse Island, and Ashmore and Cartier Islands. Australia declared a marine protected area around Ashmore Island in 1983, and around Cartier Island in 2000. Agreement The bilateral agreement establishing the MOU Box is officially known as the Australia–Indonesia Memorandum of Understanding regarding the Operations of Indonesian Traditional Fishermen in Areas of the Australian Fishing Zone and Continental Shelf – 1974. From 2001 cooperation under the Agreement has taken place through the Working Group on Marine Affairs and Fisheries, which brings together representa ...

Fisherman
A fisher or fisherman is someone who captures fish and other animals from a body of water, or gathers shellfish. Worldwide, there are about 38 million commercial and subsistence fishers and fish farmers. Fishers may be professional or recreational. Fishing has existed as a means of obtaining food since the Mesolithic period.Profile for the USA * inadequate preparation for emergencies * poor vessel maintenance and inadequate safety equipment * lack of awareness of or ignoring stability issues. Many fishers, while accepting that fishing is dangerous, staunchly defend their independence. Many proposed laws and additional regulation to increase safety have been defeated because fishers oppose them. Alaska's commercial fishers work in one of the world's harshest environments. Many of the hardships they endure include isolated fishing grounds, high winds, seasonal darkness, very cold water, icing, and short fishing seasons, where very long work days are the norm.

Helipad
A helipad is a landing area or platform for helicopters and powered lift aircraft. While helicopters and powered lift aircraft are able to operate on a variety of relatively flat surfaces, a fabricated helipad provides a clearly marked hard surface away from obstacles where such aircraft can land safely. Larger helipads, intended for use by helicopters and other vertical take-off and landing aircraft (VTOL), may be called ''vertiports.'' An example is Vertiport Chicago, which opened in 2015. Usage Helipads may be located at a heliport or airport where fuel, air traffic control and service facilities for aircraft are available. Most helipads are located remote from populated areas due to sounds, winds, space and cost constraints. However, some skyscrapers maintain a helipad on their roofs in order to accommodate air taxi services. Some basic helipads are built on top of highrise buildings for evacuation in case of a major fire outbreak. Major police departments may use a ...

Register Of The National Estate
The Register of the National Estate was a heritage register that listed natural and cultural heritage places in Australia that was closed in 2007. Phasing out began in 2003, when the Australian National Heritage List and the Commonwealth Heritage List were created and by 2007 the Register had been replaced by these and various state and territory heritage registers. Places listed on the Register remain in a non-statutory archive and are still able to be viewed via the National Heritage Database. History The register was initially compiled between 1976 and 2003 by the Australian Heritage Commission, after which the register was maintained by the Australian Heritage Council. 13,000 places were listed. The expression "national estate" was first used by the British architect Clough Williams-Ellis, and reached Australia in the 1970s.Heritage of Australia, pp. 9–13 It was incorporated into the ''Australian Heritage Commission Act 1975'' and was used to describe a collection ...
