ÃŽle Platte
Platte Island or Île Platte is an island in the Southern Coral Group that is part of the Outer Islands of the Seychelles. Geography The island is located south of the Seychelles Bank at . Coëtivy Island (also Southern Coral Group) lies further southeast. Platte Island is located south of Mahé, the main island of the Seychelles, and from their capital Victoria. The island, a low and wooded sand cay, ranges about from north to south, with a width from in the south to in the north and a land area of . Its height is 3 m above the sea level. History Platte was discovered and named in 1769 for its low topography by Lieutenant de Lampériaire of ''La Curieuse''. And it also known by its nickname ″ill Pllate″. In the 1840s there was sufficient guano on the island to make it worthwhile excavating, and it was still won in the 20th century. A visitor in 1905 stated that 1500 tons had been taken off the island the month before he arrived. He also reported on the ...

Indian Ocean
The Indian Ocean is the third-largest of the world's five oceanic divisions, covering or ~19.8% of the water on Earth's surface. It is bounded by Asia to the north, Africa to the west and Australia to the east. To the south it is bounded by the Southern Ocean or Antarctica, depending on the definition in use. Along its core, the Indian Ocean has some large marginal or regional seas such as the Arabian Sea, Laccadive Sea, Bay of Bengal, and Andaman Sea. Etymology The Indian Ocean has been known by its present name since at least 1515 when the Latin form ''Oceanus Orientalis Indicus'' ("Indian Eastern Ocean") is attested, named after India, which projects into it. It was earlier known as the ''Eastern Ocean'', a term that was still in use during the mid-18th century (see map), as opposed to the ''Western Ocean'' ( Atlantic) before the Pacific was surmised. Conversely, Chinese explorers in the Indian Ocean during the 15th century called it the Western Oceans. In Ancie ... [...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] |
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 ...

Coral Reef
A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of colonies of coral polyps held together by calcium carbonate. Most coral reefs are built from stony corals, whose polyps cluster in groups. Coral belongs to the class Anthozoa in the animal phylum Cnidaria, which includes sea anemones and jellyfish. Unlike sea anemones, corals secrete hard carbonate exoskeletons that support and protect the coral. Most reefs grow best in warm, shallow, clear, sunny and agitated water. Coral reefs first appeared 485 million years ago, at the dawn of the Early Ordovician, displacing the microbial and sponge reefs of the Cambrian. Sometimes called ''rainforests of the sea'', shallow coral reefs form some of Earth's most diverse ecosystems. They occupy less than 0.1% of the world's ocean area, about half the area of France, yet they provide a home for at least 25% of all marine species, including fish, mollusks, worms, crustaceans, echinoderms, s ...

Moyenne Island
Moyenne Island is a small island () in the Sainte Anne Marine National Park off the north coast of Mahé, Seychelles. Since the 1970s onwards, it has been a flora and fauna reserve. From 1915 until the 1960s, the island was abandoned until its purchase by Brendon Grimshaw for £8,000 (about 10,000 dollars). He was a newspaper editor from Dewsbury in Yorkshire, England. Grimshaw was the only inhabitant of the island until his death in July 2012. The island is now a national park and can be visited as part of organized trips. History The island's name was derived from the French ''moyenne'', "middle." It was supposedly used by pirates in the 18th and 19th centuries, and contains two graves called pirate graves. From 1946 to 1962 the island was owned by the late Philippe Georges. He and his wife Vera Georges had lived on the island in the early years and later moved to Mahé where they lived on the property known as Fairview. A view on the island and a beach were named after Ver ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Long Island, Seychelles
Long Island is an island in Seychelles, lying in the northeast shores of Mahe. Geography Long Island is located in the midst of the Sainte Anne Marine National Park close to Round and Moyenne Islands. This coconut palm-covered gem reaches an elevation of 90m, and features fabulous powder soft beaches and beautiful turquoise seas. History In 1825, a settlement was established on the island. A family of Seychelles purchased the islands of Long, Round and Moyenne. Their village had about 25 people and was located at the west point. In 1900 the village was abandoned and a quarantine station for small-pox sailors was built. The island served as the Seychelles juvenile prison. in 2006 the inmates were transferred to Montagne Posée Prison on the island of Mahe, to do construction work on the new land reclamation projects. The island now hosts the new Pelangi Resort and Spa which consists of 55 villas, 32 one-bedroom villas, 15 two-bedroom villas, 5 four-suite villas and a presiden ...

Monsoon
A monsoon () is traditionally a seasonal reversing wind accompanied by corresponding changes in precipitation but is now used to describe seasonal changes in atmospheric circulation and precipitation associated with annual latitudinal oscillation of the Intertropical Convergence Zone (ITCZ) between its limits to the north and south of the equator. Usually, the term monsoon is used to refer to the rainy phase of a seasonally changing pattern, although technically there is also a dry phase. The term is also sometimes used to describe locally heavy but short-term rains. The major monsoon systems of the world consist of the West African, Asia–Australian, the North American, and South American monsoons. The term was first used in English in British India and neighboring countries to refer to the big seasonal winds blowing from the Bay of Bengal and Arabian Sea in the southwest bringing heavy rainfall to the area. Etymology The etymology of the word monsoon is not ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southeast (direction)
The four cardinal directions, or cardinal points, are the four main compass directions: north, east, south, and west, commonly denoted by their initials N, E, S, and W respectively. Relative to north, the directions east, south, and west are at 90 degree intervals in the clockwise direction. The ordinal directions (also called the intercardinal directions) are northeast (NE), southeast (SE), southwest (SW), and northwest (NW). The intermediate direction of every set of intercardinal and cardinal direction is called a secondary intercardinal direction. These eight shortest points in the compass rose shown to the right are: # West-northwest (WNW) # North-northwest (NNW) # North-northeast (NNE) # East-northeast (ENE) # East-southeast (ESE) # South-southeast (SSE) # South-southwest (SSW) # West-southwest (WSW) Points between the cardinal directions form the points of the compass. Arbitrary horizontal directions may be indicated by their azimuth angle value. Determination Ad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reef
A reef is a ridge or shoal of rock, coral or similar relatively stable material, lying beneath the surface of a natural body of water. Many reefs result from natural, abiotic processes— deposition of sand, wave erosion planing down rock outcrops, etc.—but there are also reefs such as the coral reefs of tropical waters formed by biotic processes dominated by corals and coralline algae, and artificial reefs such as shipwrecks and other anthropogenic underwater structures may occur intentionally or as the result of an accident, and sometimes have a designed role in enhancing the physical complexity of featureless sand bottoms, to attract a more diverse assemblage of organisms. Reefs are often quite near to the surface, but not all definitions require this. Earth's largest coral reef system is the Great Barrier Reef in Australia, at a length of over . Biotic There is a variety of biotic reef types, including oyster reefs and sponge reefs, but the most massive and w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Running Amok
Amok syndrome is an aggressive dissociative behavioral pattern derived from Malaysia that led to the English phrase, running amok. The word derives from the Malay word , traditionally meaning "an episode of sudden mass assault against people or objects, usually by a single individual, following a period of brooding, which has traditionally been regarded as occurring especially in Malaysian culture but is now increasingly viewed as psychopathological behavior".Definition of "amok" by Oxford Dictionary on Lexico.com The syndrome of "Amok" is found in the '' Diagnostic and Statistical ...

Whaler
A whaler or whaling ship is a specialized vessel, designed or adapted for whaling: the catching or processing of whales. Terminology The term ''whaler'' is mostly historic. A handful of nations continue with industrial whaling, and one, Japan, still dedicates a single factory ship for the industry. The vessels used by aboriginal whaling communities are much smaller and are used for various purposes over the course of the year. The ''whale catcher'' was developed during the age of steam, and then driven by diesel engines throughout much of the twentieth century. It was designed with a harpoon gun mounted at its bow and was fast enough to chase and catch rorquals such as the fin whale. At first, whale catchers either brought the whales they killed to a whaling station, a settlement ashore where the carcasses could be processed, or to its factory ship anchored in a sheltered bay or inlet. With the later development of the slipway at the ship's stern, whale catchers were able t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quarantine
A quarantine is a restriction on the movement of people, animals and goods which is intended to prevent the spread of disease or pests. It is often used in connection to disease and illness, preventing the movement of those who may have been exposed to a communicable disease, yet do not have a confirmed medical diagnosis. It is distinct from medical isolation, in which those confirmed to be infected with a communicable disease are isolated from the healthy population. Quarantine considerations are often one aspect of border control. The concept of quarantine has been known since biblical times, and is known to have been practised through history in various places. Notable quarantines in modern history include the village of Eyam in 1665 during the bubonic plague outbreak in England; East Samoa during the 1918 flu pandemic; the Diphtheria outbreak during the 1925 serum run to Nome, the 1972 Yugoslav smallpox outbreak, the SARS pandemic, the Ebola pandemic and extensive ...
