Heron Island, Australia
Heron Island is a coral cay located near the Tropic of Capricorn in the southern Great Barrier Reef. It is north-east of Gladstone, Queensland, Australia, and north-north-west of the state capital Brisbane. The island is situated on the leeward (western) side of Heron Reef, a fringing platform reef of significant biodiversity, supporting around 900 of the 1,500 fish species and 72% of the coral species found on the Great Barrier Reef.University of Queensland Centre for Marine StudiesIsland Research Station. Retrieved 2006-JUL-14. During the summer months Heron Island is also home to over 200,000 birds including Noddy Terns and Mutton Birds. The island is about long and at its widest, giving an area of approximately . The highest point, near the western tip, is above sea level. A dune ridge along the southern shore rises some above sea level, lower dunes on the north-eastern side are only about above the sea. Heron Island and an extrapolated version of the research sta ...

North-northeast
The points of the compass are a set of horizontal, radially arrayed compass directions (or azimuths) used in navigation and cartography. A ''compass rose'' is primarily composed of four cardinal directions—north, east, south, and west—each separated by 90 degrees, and secondarily divided by four ordinal (intercardinal) directions—northeast, southeast, southwest, and northwest—each located halfway between two cardinal directions. Some disciplines such as meteorology and navigation further divide the compass with additional azimuths. Within European tradition, a fully defined compass has 32 "points" (and any finer subdivisions are described in fractions of points). Compass points or compass directions are valuable in that they allow a user to refer to a specific azimuth in a colloquial fashion, without having to compute or remember degrees. Designations The names of the compass point directions follow these rules: 8-wind compass rose * The four cardinal directio ...

Heron Island, Australia - Harbour And HIRS From Helicopter
Herons are long-legged, long-necked, freshwater and coastal birds in the family Ardeidae, with 75 recognised species, some of which are referred to as egrets or bitterns rather than herons. Members of the genus ''Botaurus'' are referred to as bitterns, and, together with the zigzag heron, or zigzag bittern, in the monotypic genus ''Zebrilus'', form a monophyletic group within the Ardeidae. Egrets do not form a biologically distinct group from herons, and tend to be named differently because they are mainly white or have decorative plumes in breeding plumage. Herons, by evolutionary adaptation, have long beaks. The classification of the individual heron/egret species is fraught with difficulty, and no clear consensus exists about the correct placement of many species into either of the two major genera, ''Ardea (genus), Ardea'' and ''Egretta''. Similarly, the relationships of the genus, genera in the family are not completely resolved. However, one species formerly considered to c ...

Scuba Diving
Scuba diving is a Diving mode, mode of underwater diving whereby divers use Scuba set, breathing equipment that is completely independent of a surface breathing gas supply, and therefore has a limited but variable endurance. The word ''scuba'' is an Acronym#Normal case and acronyms, acronym for "Self-Contained Underwater Breathing Apparatus" and was coined by Christian J. Lambertsen in a patent submitted in 1952. Scuba divers carry their own source of breathing gas, affording them greater independence and movement than surface-supplied divers, and more time underwater than freedivers. Although the use of compressed air is common, other gas blends are also used. Open-circuit scuba systems discharge the breathing gas into the environment as it is exhaled and consist of one or more diving cylinders containing breathing gas at high pressure which is supplied to the diver at ambient pressure through a diving regulator. They may include additional cylinders for range extension, de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HMAS Protector (1884)
HMCS (later HMAS) ''Protector'' was a large flat-iron gunboat commissioned and purchased by the South Australian government in 1884, for the purpose of defending the local coastline against possible attacks in the aftermath of the 'Russo-Turkish War (1877–1878), Russian scare', of the 1870s. She arrived in Adelaide in September 1884 and served in the Boxer Rebellion, World War I and World War II. During July 1943, ''Protector'' was requisitioned for war service by the United States Army, U.S. Army. On the way to New Guinea and off Gladstone, Queensland, Gladstone, she was damaged in a collision with a tug and abandoned. The hull was taken to Heron Island, Australia, Heron Island off the Queensland coast and later sunk for use as a Breakwater (structure), breakwater. Her rusting remains are still visible to this day. Description and armament Built by Armstrong Whitworth, Sir WG Armstrong, Mitchell & Co, Newcastle upon Tyne, England, ''Protector'' was built to a standard type ...

National Park
A national park is a nature park designated for conservation (ethic), conservation purposes because of unparalleled national natural, historic, or cultural significance. It is an area of natural, semi-natural, or developed land that is protected and owned by a government. Although governments hold different standards for national park designation, the conservation of 'wild nature' for posterity and as a symbol of national pride is a common motivation for the continued protection of all national parks around the world. National parks are almost always accessible to the public.Gissibl, B., S. Höhler and P. Kupper, 2012, ''Civilizing Nature, National Parks in Global Historical Perspective'', Berghahn, Oxford Usually national parks are developed, owned and managed by national governments, though in some countries with federal government, federal or Devolution, devolved forms of government, "national parks" may be the responsibility of subnational, regional, or local authorities.

Fishery
Fishery can mean either the enterprise of raising or harvesting fish and other aquatic life or, more commonly, the site where such enterprise takes place ( a.k.a., fishing grounds). Commercial fisheries include wild fisheries and fish farms, both in freshwater waterbodies (about 10% of all catch) and the oceans (about 90%). About 500 million people worldwide are economically dependent on fisheries. 171 million tonnes of fish were produced in 2016, but overfishing is an increasing problem, causing declines in some populations. Because of their economic and social importance, fisheries are governed by complex fisheries management practices and legal regimes that vary widely across countries. Historically, fisheries were treated with a " first-come, first-served" approach, but recent threats from human overfishing and environmental issues have required increased regulation of fisheries to prevent conflict and increase profitable economic activity on the fishery.

Green Turtle
The green sea turtle (''Chelonia mydas''), also known as the green turtle, black (sea) turtle or Pacific green turtle, is a species of large sea turtle of the family Cheloniidae. It is the only species in the genus ''Chelonia''. Its range extends throughout tropical and subtropical seas around the world, with two distinct populations in the Atlantic and Pacific Oceans, but it is also found in the Indian Ocean. The common name refers to the usually green fat found beneath its carapace, due to its diet strictly being seagrass, not to the color of its carapace, which is olive to black. The dorsoventrally flattened body of ''C. mydas'' is covered by a large, teardrop-shaped carapace; it has a pair of large, paddle-like flippers. It is usually lightly colored, although in the eastern Pacific populations, parts of the carapace can be almost black. Unlike other members of its family, such as the hawksbill sea turtle, ''C. mydas'' is mostly herbivorous. The adults usually inhabit ...

Canning
Canning is a method of food preservation in which food is processed and sealed in an airtight container (jars like Mason jars, and steel and tin cans). Canning provides a shelf life that typically ranges from one to five years, although under specific circumstances, it can be much longer. A freeze-dried canned product, such as canned dried lentils, could last as long as 30 years in an edible state. In 1974, samples of canned food from the wreck of the ''Bertrand (steamboat), Bertrand'', a steamboat that sank in the Missouri River in 1865, were tested by the National Food Processors Association. Although appearance, smell, and vitamin content had deteriorated, there was no trace of microbial growth and the 109-year-old food was determined to be still safe to eat. History and development French origins Shortly before the Napoleonic Wars, the French government offered a hefty cash award of 12,000 francs to any inventor who could devise a cheap and effective method of preser ...

Charles Bampfield Yule
Captain Charles Bampfield Yule, R.N. (1806 – 1 November 1878 at Anderton, Cornwall, United Kingdom) was an explorer and author of the Admiralty ''Australia Directory.'' The third son of Commander John Yule RN who served with Nelson at Trafalgar and a mother who was the daughter of Bampfield Carslake, Charles Bampfield Yule was the brother of the Reverend John Carslake Duncan Yule. While a Lieutenant, he commanded as part of the surveying expedition led by Frances Blackwood from 1842 to 1845. Yule discovered and named Heron Island off Queensland, Australia on 11 January 1843. He continued on to survey the coast of New Guinea in 1846 and assisted Owen Stanley in his New Guinea expedition of 1848–1849. Although Yule claimed New Guinea for Great Britain, his claim was not recognised by the British government (although Great Britain was later to officially claim southeastern New Guinea in 1884). His survey work was incorporated into volumes of the ''Australia Directory'' fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lieutenant
A lieutenant ( , ; abbreviated Lt., Lt, LT, Lieut and similar) is a Junior officer, junior commissioned officer rank in the armed forces of many nations, as well as fire services, emergency medical services, Security agency, security services and police forces. The rank in armies and air forces is often subdivided into subcategories of seniority. In Comparative navy officer ranks of Anglophone countries, English-speaking navies, lieutenants are often equivalent to the army rank of Captain (armed forces), captain; in other navies, the lieutenants are usually equal to their army counterparts. ''Lieutenant'' may also appear as part of a title used in various other organisations with a codified command structure. It often designates someone who is "second-in-command", and as such, may precede the name of the rank directly above it. For example, a "lieutenant master" is likely to be second-in-command to the "master" in an organisation using both ranks. Political uses include lieu ...

Francis Price Blackwood
Francis Price Blackwood (25 May 1809 – 22 March 1854) was a United Kingdom of Great Britain and Ireland, British naval officer who while posted at several different locations during his time in the Royal Navy, spent much of his time posted in colonial Australia and was an instrumental pioneer of regions near Australia's east coast and nearby islands. Blackwood was the second son of Vice-Admiral Sir Henry Blackwood and his third wife, Harriet née Gore, Blackwood entered the navy at age twelve. He was commissioned 8 Aug 1828 and joined under Captain Frederick Marryat. He then served on under Captain Charles Yorke, 4th Earl of Hardwicke, Charles Yorke. It was in 1833 that Blackwood was appointed to be in command of HMS Hyacinth (1829), HMS ''Hyacinth'', a ship which would take him to Australia on his first visit and in which he would travel to the north-east coast to gather hydrographic data. In 1838 Blackwood received a promotion to the rank of Captain (naval), captain. V ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cutter (boat)
A cutter is any of various types of watercraft. The term can refer to the sail plan, rig (sail plan) of a sailing vessel (but with regional differences in definition), to a governmental enforcement agency vessel (such as a coast guard or border force cutter), to a type of ship's boat which can be used under sail or oars, or, historically, to a type of fast-sailing vessel introduced in the 18th century, some of which were used as small warships. As a sailing rig, a cutter is a single-masted boat, with two or more headsails. On the eastern side of the Atlantic Ocean, Atlantic, the two headsails on a single mast is the fullest extent of the modern definition. In U.S. waters, a greater level of complexity applies, with the placement of the mast and the rigging details of the bowsprit taken into account so a boat with two headsails may be classed as a sloop. Government agencies use the term "cutter" for vessels employed in patrolling their territorial waters and other enforcement a ...
