Farquhar Atoll
The Farquhar Atoll is part of the Farquhar Group of islands in the Seychelles, part of the Outer Islands chain. It is located southwest of Mahé Island and the capital, Victoria, north of Madagascar, and around from the East African mainland. History The atoll was named in honor of Robert Townsend Farquhar in 1824. Fishing camps were established on North Island in 1850. From the early to mid- sixteenth century, the atoll had been vaguely named after Portuguese explorer João da Nova, who first encountered Farquhar and the Outer Islands while commandeering his country's expedition to India in 1504. Administration of the islands were a grey area for a time, with both Mauritius and Seychelles claiming ownership. In 1881, officials in Seychelles suggested that Farquhar Atoll (along with several other outer islands) be administered from their capital, Victoria, rather than from Mauritius. There were objections, as the owners at that time were based in Mauritius; after considerable ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indian Ocean
The Indian Ocean is the third-largest of the world's five oceanic divisions, covering or approximately 20% of the water area of Earth#Surface, Earth's surface. It is bounded by Asia to the north, Africa to the west and Australia (continent), Australia to the east. To the south it is bounded by the Southern Ocean or Antarctica, depending on the definition in use. The Indian Ocean has large marginal or regional seas, including the Andaman Sea, the Arabian Sea, the Bay of Bengal, and the Laccadive Sea. Geologically, the Indian Ocean is the youngest of the oceans, and it has distinct features such as narrow continental shelf, continental shelves. Its average depth is 3,741 m. It is the warmest ocean, with a significant impact on global climate due to its interaction with the atmosphere. Its waters are affected by the Indian Ocean Walker circulation, resulting in unique oceanic currents and upwelling patterns. The Indian Ocean is ecologically diverse, with important ecosystems such ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
João Da Nova
João da Nova (; ; ; in Maceda, Ourense, Galicia, Spain – July 16, 1509, in Kochi, India) was a Galician-born explorer in the service of Portugal. He is credited as the discoverer of Ascension and Saint Helena islands. The Juan de Nova Island, in the Mozambique Channel, is named after him. The Farquhar atoll (in the Seychelles) was, for a long time, known as the João da Nova islands.The appellation 'João da Nova islands' for the Farquhar atoll appeared in most European navigational charts until the 19th century, when they were renamed after British Mauritius governor Robert Townsend Farquhar, to avoid confusion with the Mozambique Channel island. It is sometimes thought that the Agaléga islands (in the Indian Ocean) were also named after him (although it is almost certain he never visited them).Theories behind the 'Agalega' name are reviewed by Robert Scott (1961) ''Limuria: The Lesser Dependencies of Mauritius'' Biography Juan da Nova was born into a noble family ...

Birdwatching
Birdwatching, or birding, is the observing of birds, either as a recreational activity or as a form of citizen science. A birdwatcher may observe by using their naked eye, by using a visual enhancement device such as binoculars or a telescope, by listening for bird sounds, watching public webcams, or by viewing smart bird feeder cameras. Most birdwatchers pursue this activity for recreational or social reasons, unlike ornithologists, who engage in the study of birds using formal scientific methods. Birding, birdwatching, and twitching The first recorded use of the term ''birdwatcher'' was in 1712 by William Oldsworth. The term ''birding'' was also used for the practice of ''fowling'' or hunting with firearms as in Shakespeare's '' The Merry Wives of Windsor'' (1602): "She laments sir... her husband goes this morning a-birding." The terms ''birding'' and ''birdwatching'' are today used by some interchangeably, although some participants prefer ''birding'', partly because ...

Important Bird Area
An Important Bird and Biodiversity Area (IBA) is an area identified using an internationally agreed set of criteria as being globally important for the conservation of bird populations. IBA was developed and sites are identified by BirdLife International. There are over 13,000 IBAs worldwide. These sites are small enough to be entirely conserved and differ in their character, habitat or ornithological importance from the surrounding habitat. In the United States the program is administered by the National Audubon Society. Often IBAs form part of a country's existing protected area network, and so are protected under national legislation. Legal recognition and protection of IBAs that are not within existing protected areas varies within different countries. Some countries have a National IBA Conservation Strategy, whereas in others protection is completely lacking. History In 1985, following a specific request from the European Economic Community, Birdlife International dr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Island Conservation Society
The Island Conservation Society (ICS) was registered as an NGO in Seychelles on 25 March 2001. The Head Office, known as The Island Conservation Centre, is situated at Pointe Larue, Mahé. ICS focuses on the protection and rehabilitation of the small islands of Seychelles, particularly the outer islands. Most of the outer islands of Seychelles are Government-owned and managed by the parastal company Islands Development Company (IDC). In 2007, ICS signed an agreement with IDC for conservation management on these islands. ICS now employs full-time scientists and rangers at conservation centres on six IDC islands, Silhouette Island, Alphonse Atoll, Desroches Island, Farquhar Atoll, Astove and Cosmoledo. ICS has also managed Aride Island Nature Reserve since October 2003. Aride was previously owned and managed by the Royal Society of Wildlife Trusts (RSWT) of UK. In October 2003, the reserve was leased to ICS and a series of conservation targets were set by RSWT. In 2006, upon sa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Geographic Coordinate System
A geographic coordinate system (GCS) is a spherical coordinate system, spherical or geodetic coordinates, geodetic coordinate system for measuring and communicating position (geometry), positions directly on Earth as latitude and longitude. It is the simplest, oldest, and most widely used type of the various spatial reference systems that are in use, and forms the basis for most others. Although latitude and longitude form a coordinate tuple like a cartesian coordinate system, the geographic coordinate system is not cartesian because the measurements are angles and are not on a planar surface. A full GCS specification, such as those listed in the EPSG Geodetic Parameter Dataset, EPSG and ISO 19111 standards, also includes a choice of geodetic datum (including an Earth ellipsoid), as different datums will yield different latitude and longitude values for the same location. History The invention of a geographic coordinate system is generally credited to Eratosthenes of Cy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sand Dune
A dune is a landform composed of wind- or water-driven sand. It typically takes the form of a mound, ridge, or hill. An area with dunes is called a dune system or a dune complex. A large dune complex is called a dune field, while broad, flat regions covered with wind-swept sand or dunes, with little or no vegetation, are called '' ergs'' or ''sand seas''. Dunes occur in different shapes and sizes, but most kinds of dunes are longer on the stoss (upflow) side, where the sand is pushed up the dune, and have a shorter ''slip face'' in the lee side. The valley or trough between dunes is called a ''dune slack''. Dunes are most common in desert environments, where the lack of moisture hinders the growth of vegetation that would otherwise interfere with the development of dunes. However, sand deposits are not restricted to deserts, and dunes are also found along sea shores, along streams in semiarid climates, in areas of glacial outwash, and in other areas where poorly cemented san ...

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 Estuary, 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, reef, 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 J ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fly Fishing
Fly fishing is an angling technique that uses an ultra-lightweight lure called an artificial fly, which typically mimics small invertebrates such as flying and aquatic insects to attract and catch fish. Because the mass of the fly lure is insufficient to overcome air resistance, it cannot be launched far using conventional gears and techniques, so specialized tackles are used instead and the casting techniques are significantly different from other forms of angling. It is also very common for the angler to wear waders, carry a hand net, and stand in the water when fishing. Fly fishing primarily targets predatory fish that have significant amount of very small-sized prey in their diet, and can be done in fresh or saltwater. North Americans usually distinguish freshwater fishing between cold-water species (trout, salmon) and warm-water species (notably black bass). In Britain, where natural water temperatures vary less, the distinction is between game fishing for trout ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Catch And Release
Catch and release is a practice within recreational fishing where after capture the fish is Fish hook, unhooked and returned live to the water. Originally adopted in the United Kingdom by Coarse fishing, coarse fishermen to Overfishing, preserve fish populations, it has since become a widely used technique to permit people to fish recreationally while ensuring sustainability in the face of growing human populations, mounting ecological pressure, increasingly effective fishing tackle and techniques, inadequate fishing regulations and enforcement, and habitat degradation. Between 18-20% of fish released die from injuries and stress, although the rate varies by species. Among those that survive, their injuries may significantly reduce their ability to feed and grow. During tournaments, inadequate holding and weighing procedures may further increase mortality. With deep sea fishing in particular, fish are typically unable to adjust their physiology to the Barotrauma, sudden pressur ...

Cyclone Fantala
Very Intense Tropical Cyclone Fantala was the List of the most intense tropical cyclones, most intense tropical cyclone recorded in the South-West Indian Ocean tropical cyclone, South-West Indian Ocean in terms of sustained winds. Part of the 2015–16 South-West Indian Ocean cyclone season, 2015–16 cyclone season, Fantala formed on 11 April to the south of Diego Garcia, an island in the central Indian Ocean. With a ridge (meteorology), ridge to the south, the storm moved westward for several days while gaining strength, aided by warm waters and decreasing wind shear. Late on 17 April, the Météo-France office on Réunion (MFR) estimated peak 10-minute maximum sustained winds, winds of , making Fantala the strongest tropical cyclone of the basin in terms of 10-minute sustained winds. The Joint Typhoon Warning Center (JTWC) estimated peak 1-minute winds of , equivalent to Category 5 intensity on the Saffir-Simpson Hurricane Wind Scale, Saffir-Simpson scale, also the strongest on ...
