Lihou Reef
Lihou Reef National Nature Reserve is a former marine protected area covering an area of 8440 km2 in the Australian Coral Sea Islands Territory that was incorporated into the new Coral Sea Commonwealth Marine Reserve in December 2012. Together with the Coringa-Herald National Nature Reserve, from which it is separated by about 100 km of open ocean, it forms the Coral Sea Reserves Ramsar Site, designated on 16 August 2002, listing it under the Ramsar Convention as a wetland of international importance. History Lihou Reef and its cays were discovered by Lieutenant John Lihou, R.N., on 23 February 1823. Lihou, then Master of the brig-sloop HMS ''Zenobia'', was on passage from Manila to South America. After a hazardous passage through the reef, the ship departed the Great Barrier Reef via an opening near Murray Islands. On 23 February, the Lihou Reefs were sighted.''Source: Hydrographic Service - Royal Australian Navy. (M.A. BOLGER. Lieutenant Commander RAN for DI ...

Great Barrier Reef
The Great Barrier Reef is the world's largest coral reef system composed of over 2,900 individual reefs and 900 islands stretching for over over an area of approximately . The reef is located in the Coral Sea, off the coast of Queensland, Australia, separated from the coast by a channel 100 miles wide in places and over 200 feet deep. The Great Barrier Reef can be seen from outer space and is the world's biggest single structure made by living organisms. This reef structure is composed of and built by billions of tiny organisms, known as coral polyps. It supports a wide diversity of life and was selected as a World Heritage Site in 1981. CNN labelled it one of the seven natural wonders of the world in 1997. Australian World Heritage places included it in its list in 2007. The Queensland National Trust named it a state icon of Queensland in 2006. A large part of the reef is protected by the Great Barrier Reef Marine Park, which helps to limit the impact of human use, such a ...

Protected Areas Disestablished In 2012
Protection is any measure taken to guard a thing against damage caused by outside forces. Protection can be provided to physical objects, including organisms, to systems, and to intangible things like civil and political rights. Although the mechanisms for providing protection vary widely, the basic meaning of the term remains the same. This is illustrated by an explanation found in a manual on electrical wiring: Some kind of protection is a characteristic of all life, as living things have evolved at least some protective mechanisms to counter damaging environmental phenomena, such as ultraviolet light. Biological membranes such as bark on trees and skin on animals offer protection from various threats, with skin playing a key role in protecting organisms against pathogens and excessive water loss. Additional structures like scales and hair offer further protection from the elements and from predators, with some animals having features such as spines or camouflage servin ...

Former Protected Areas Of The Australian Government
A former is an object, such as a template, gauge or cutting die, which is used to form something such as a boat's hull. Typically, a former gives shape to a structure that may have complex curvature. A former may become an integral part of the finished structure, as in an aircraft fuselage, or it may be removable, being using in the construction process and then discarded or re-used. Aircraft formers Formers are used in the construction of aircraft fuselage, of which a typical fuselage has a series from the nose to the empennage, typically perpendicular to the longitudinal axis of the aircraft. The primary purpose of formers is to establish the shape of the fuselage and reduce the column length of stringers to prevent instability. Formers are typically attached to longerons, which support the skin of the aircraft. The "former-and-longeron" technique (also called stations and stringers) was adopted from boat construction, and was typical of light aircraft built until the ...

Lagoon
A lagoon is a shallow body of water separated from a larger body of water by a narrow landform, such as reefs, barrier islands, barrier peninsulas, or isthmuses. Lagoons are commonly divided into ''coastal lagoons'' (or ''barrier lagoons'') and ''atoll lagoons''. They have also been identified as occurring on mixed-sand and gravel coastlines. There is an overlap between bodies of water classified as coastal lagoons and bodies of water classified as estuaries. Lagoons are common coastal features around many parts of the world. Definition and terminology Lagoons are shallow, often elongated bodies of water separated from a larger body of water by a shallow or exposed shoal, coral reef, or similar feature. Some authorities include fresh water bodies in the definition of "lagoon", while others explicitly restrict "lagoon" to bodies of water with some degree of salinity. The distinction between "lagoon" and "estuary" also varies between authorities. Richard A. Davis Jr. restrict ...

Lansdowne Bank
Lansdowne Bank, sometimes called Landsdowne Bank, is an extensive submerged bank located between the main island of New Caledonia and the Chesterfield Islands, in the easternmost part of the Coral Sea. It covers an area of , p. 26 making it one of the largest banks of the world, has general depths of , and a largely sandy bottom. Two reefs mark the shallowest spots of the bank, but they are still submerged at low tide. Fairway Ridge, also called Fairway Plateau, is a submarine feature shown on some maps in that area. The Lansdowne Bank area marked is far larger than Fairway Plateau, but there are smaller, unnamed plateaus nearby.

Chesterfield Islands
The Chesterfield Islands (''îles Chesterfield'' in French) are a French archipelago of New Caledonia located in the Coral Sea, northwest of Grande Terre, the main island of New Caledonia. The archipelago is 120 km long and 70 km broad, made up of 11 uninhabited islets and many reefs. The land area of the islands is less than 10 km2. During periods of lowered sea level during the Pleistocene ice ages, an island of considerable size (Greater Chesterfield Island) occupied the location of the archipelago. Bellona Reef, 164 km south-southeast of Chesterfield, is geologically separated from the Chesterfield archipelago but commonly included. Etymology The reef complex is named after the whaling ship , commanded by Matthew Bowes Alt, which sailed through the Coral Sea in the 1790s. Location The Chesterfield Islands, sometimes referred to as the ''Chesterfield Reefs'' or ''Chesterfield Group'', are the most important of a number of uninhabited coral sand ...

Coral Sea
The Coral Sea () is a marginal sea of the South Pacific off the northeast coast of Australia, and classified as an interim Australian bioregion. The Coral Sea extends down the Australian northeast coast. Most of it is protected by the French Natural Park of the Coral Sea (french: Parc Naturel de la Mer de Corail) and the Australian Coral Sea Marine Park. The sea was the location for the Battle of the Coral Sea, a major confrontation during World War II between the navies of the Empire of Japan, and the United States and Australia. The sea contains numerous islands and reefs, as well as the world's largest reef system, the Great Barrier Reef (GBR), which was declared a World Heritage Site by UNESCO in 1981. All previous oil exploration projects were terminated at the GBR in 1975, and fishing is restricted in many areas. The reefs and islands of the Coral Sea are particularly rich in birds and aquatic life and are a popular tourist destination, both domestically and internat ...

Atoll
An atoll () is a ring-shaped island, including a coral rim that encircles a lagoon partially or completely. There may be coral islands or cays on the rim. Atolls are located in warm tropical or subtropical oceans and seas where corals can grow. Most of the approximately 440 atolls in the world are in the Pacific Ocean. Two different, well-cited models, the subsidence and antecedent karst models, have been used to explain the development of atolls.Droxler, A.W. and Jorry, S.J., 2021. ''The Origin of Modern Atolls: Challenging Darwin's Deeply Ingrained Theory.'' ''Annual Review of Marine Science'', 13, pp.537-573. According to Charles Darwin's ''subsidence model'', the formation of an atoll is explained by the subsidence of a volcanic island around which a coral fringing reef has formed. Over geologic time, the volcanic island becomes extinct and eroded as it subsides completely beneath the surface of the ocean. As the volcanic island subsides, the coral fringing reef becomes a ...

Murray Islands
Murray Islands is a group of small islands southeast of Cape Whitson, off the south coast of Laurie Island in the South Orkney Islands. Discovered in 1823 by Matthew Brisbane, who explored the south coast of Laurie Island under the direction of James Weddell James Weddell (24 August 1787 – 9 September 1834) was a British sailor, navigator and seal hunter who in February 1823 sailed to latitude of 74° 15′ S—a record 7.69 degrees or 532 statute miles south of the Antarc .... The name " Murrys Islands" appears on Weddell's chart, but the islands are probably named for James Murray of London, maker of the chronometers used on Weddell's voyage.
