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 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] |
Guano
Guano (Spanish from ) is the accumulated excrement of seabirds or bats. Guano is a highly effective fertiliser 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 Intensive farming, input-intensive farming. The demand for guano spurred the human colonisation 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, Fungus, fungi, invertebrates, and vertebrates. The loss of bats from a cave can result in the extinction of species that rely on their guano ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atoll
An atoll () is a ring-shaped island, including a coral rim that encircles a lagoon. There may be coral islands or cays on the rim. Atolls are located in warm tropical or subtropical parts of the oceans and seas where corals can develop. Most of the approximately 440 atolls in the world are in the Pacific Ocean. Two different, well-cited models, the subsidence model and the antecedent karst model, 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 sinking 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 ba ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, ...

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. 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 Moyenne Island, named after the French word for "middle", has a rich history. Pirates allegedly used the island in the 18th and 19th centuries, and two "pirate graves" remain. Philippe Georges owned the island from 1946 to 1962, living there with his wife Vera before moving to Mahé. The island features a viewpoint and beach named after Vera. In 1962, Brendon Grimshaw bought the island from Philippe Georges for £8,000 (). Grimshaw and René Antoine Lafortune transformed t ...

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. The island is covered in palm trees and reaches an elevation of 90m. 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 presidential villa. The hotel features Seychelles’ first funicular ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monsoon
A monsoon () is traditionally a seasonal reversing wind accompanied by corresponding changes in precipitation but is now used to describe seasonal changes in Atmosphere of Earth, 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 Wet season, 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 Monsoon#Africa (West African and Southeast African), West African, Asian–Australian monsoon, Australian, the North American monsoon, North American, and South American monsoons. The term was first Glossary of the British Raj, used in English in British India and neighboring countries to refer to the big seasonal winds blowin ...

Southeast (direction)
The four cardinal directions or cardinal points are the four main compass directions: north (N), south (S), east (E), and west (W). The corresponding azimuths (clockwise horizontal angle from north) are 0°, 90°, 180°, and 270°. The four ordinal directions or intercardinal directions are northeast (NE), southeast (SE), southwest (SW), and northwest (NW). The corresponding azimuths are 45°, 135°, 225°, and 315°. The intermediate direction of every pair of neighboring cardinal and intercardinal directions 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 ... [...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 component, abiotic (non-living) processes such as deposition (geology), deposition of sand or wave erosion planning down rock outcrops. However, reefs such as the coral reefs of tropical waters are formed by biotic component, biotic (living) processes, dominated by corals and coralline algae. Artificial reefs, such as shipwrecks and other man-made underwater structures, may occur intentionally or as the result of an accident. These are sometimes designed to increase the physical complexity of featureless sand bottoms to attract a more diverse range of organisms. They provide shelter to various aquatic animals which help prevent extinction. Another reason reefs are put in place is for aquaculture, and fish farmers who are looking to improve their businesses sometimes invest in them. Reefs are often quite n ...

Running Amok
Amok syndrome is an aggressive dissociative behavioral pattern derived from the Malay world, modern Indonesia and Malaysia, which led to the English phrase ''running amok''. The word derives from the Malay language, Malay word , traditionally meaning "rushing in a frenzy" or "attacking furiously".Definition of "amok" by Oxford Dictionary on Lexico.com Amok syndrome presents as an episode of sudden mass assault against people or objects following a period of brooding, which has traditionally been regarded as occurring especially in Malay culture but is now increasingly viewed as psychopathological behavior. The syndrome of "Amok" is found in the ''Diagnostic and Statistical Manual of Mental Disorders'' (DSM-IV TR). [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Steam-powered vesselage , 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 cat ... [...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. 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 quarantines applied throughout the world during the COVID-19 pande ...
