Sesostris Bank
Sesostris Bank is a submerged bank or sunken atoll belonging to the Amindivi Subgroup of islands of the Union Territory of Lakshadweep, India, and has a distance of south of the city of Delhi. Geography It is the second largest feature of Lakshadweep, after Bassas de Pedro, with a lagoon area of . It is also one of the northernmost features, after Cora Divh and Bassas de Pedro. Those coral banks, all submerged, form the north of Lakshadweep. Sesostris Bank is about 22 km in diameter. There are no emergent cays or islands. Depths range from 20 to 77 meters. Depths near the bank reach 700 meters.

Lakshadweep
Lakshadweep (), also known as Laccadives (), is a union territory of India. It is an archipelago of 36 islands in the Arabian sea, located off the Malabar Coast. The name ''Lakshadweep'' means "one lakh islands" in Sanskrit, though the Laccadive Islands are just one part of the archipelago of no more than a hundred islands. Malayalam is the primary as well as the widely spoken native language in the territory. The islands form the smallest union territory of India and their total surface area is just . The lagoon area covers about , the territorial waters area and the exclusive economic zone area . The region forms a single Indian district with 10 subdivisions. Kavaratti serves as the capital of the Union Territory and the region comes under the jurisdiction of Kerala High Court. The islands are the northernmost of the Lakshadweep–Maldives–Chagos group of islands, which are the tops of a vast undersea mountain range, the Chagos-Laccadive Ridge, Chagos-Lakshadweep Ridge ...

Bank (topography)
An ocean bank, sometimes referred to as a fishing bank or simply bank, is a part of the seabed that is shallow compared to its surrounding area, such as a shoal or the top of an underwater hill. Somewhat like continental slopes, ocean bank slopes can upwell as tidal and other flows intercept them, sometimes resulting in nutrient-rich currents. Because of this, some large banks, such as Dogger Bank and the Grand Banks of Newfoundland, are among the richest fishing grounds in the world. There are some banks that were reported in the 19th century by navigators, such as Wachusett Reef, whose existence is doubtful. Types Ocean banks may be of volcanic nature. Banks may be carbonate or terrigenous. In tropical areas some banks are submerged atolls. As they are not associated with any landmass, banks have no outside source of sediments. Carbonate banks are typically platforms, rising from the ocean depths, whereas terrigenous banks are elevated sedimentary deposits. Seamounts, by ...

Reefs Of The Indian Ocean
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 widely ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Undersea Banks Of Lakshadweep
The underwater environment is the region below the surface of, and immersed in, liquid water in a natural or artificial feature (called a body of water), such as an ocean, sea, lake, pond, reservoir, river, canal, or aquifer. Some characteristics of the underwater environment are universal, but many depend on the local situation. Liquid water has been present on Earth for most of the history of the planet. The underwater environment is thought to be the place of the origin of life on Earth, and it remains the ecological region most critical to the support of life and the natural habitat of the majority of living organisms. Several branches of science are dedicated to the study of this environment or specific parts or aspects of it. A number of human activities are conducted in the more accessible parts of the underwater environment. These include research, underwater diving for work or recreation, and underwater warfare with submarines. It is hostile to humans in many ways an ...

Indian Navy
The Indian Navy is the maritime branch of the Indian Armed Forces. The President of India is the Supreme Commander of the Indian Navy. The Chief of Naval Staff, a four-star admiral, commands the navy. As a blue-water navy, it operates significantly in the Persian Gulf Region, the Horn of Africa, the Strait of Malacca, and routinely conducts anti-piracy operations and partners with other navies in the region. It also conducts routine two to three month-long deployments in the South and East China seas as well as the western Mediterranean sea simultaneously. The primary objective of the navy is to safeguard the nation's maritime borders, and in conjunction with other Armed Forces of the union, act to deter or defeat any threats or aggression against the territory, people or maritime interests of India, both in war and peace. Through joint exercises, goodwill visits and humanitarian missions, including disaster relief, the Indian Navy promotes bilateral relations between n ...

Steam Frigate
Steam frigates (including screw frigates) and the smaller steam corvettes, steam sloops, steam gunboats and steam schooners, were steam-powered warships that were not meant to stand in the line of battle. There were some exceptions like for example the French Napoléon class steam ship of the line was meant to stand in the line of battle, making it the world's first steam battleship. The first such ships were paddle steamers. Later on the invention of screw propulsion enabled construction of steam-powered versions of the traditional ships of the line, frigates, corvettes, sloops and gunboats. Evolution First steam warships The first small vessel that can be considered a steam warship was the ''Demologos'', which was launched in 1815 for the United States Navy. From the early 1820s, the British Navy began building a number of small steam warships including the armed tugs and , and by the 1830s the navies of America, Russia and France were experimenting with steam-powered wa ...

Diameter
In geometry, a diameter of a circle is any straight line segment that passes through the center of the circle and whose endpoints lie on the circle. It can also be defined as the longest chord of the circle. Both definitions are also valid for the diameter of a sphere. In more modern usage, the length d of a diameter is also called the diameter. In this sense one speaks of diameter rather than diameter (which refers to the line segment itself), because all diameters of a circle or sphere have the same length, this being twice the radius r. :d = 2r \qquad\text\qquad r = \frac. For a convex shape in the plane, the diameter is defined to be the largest distance that can be formed between two opposite parallel lines tangent to its boundary, and the is often defined to be the smallest such distance. Both quantities can be calculated efficiently using rotating calipers. For a curve of constant width such as the Reuleaux triangle, the width and diameter are the same because all ...

Cora Divh
Cora Divh, also called Coradeeve or Little Bassas de Pedro Bank (''cf.'' Great Bassas de Pedro), is a submerged bank or sunken atoll belonging to the Amindivi Subgroup of islands of the Union Territory of Lakshadweep, India. It has a distance of south of the city of Delhi. History An Indian patrol ship is named after this bank. Geography Cora Divh is the third largest feature of Lakshadweep, after Bassas de Pedro and Sesostris Bank, with a lagoon area of . It is also the northernmost feature, reaching to 13°58'N. Those coral banks, all submerged, form the north of Lakshadweep. Adas Bank, which lies 90 km to the north of Cora Divh, is the same type of formation but is not part of Lakshadweep. Cora Divh is 42 km long southwest–northeast, and 12 about km wide. Its southwest point is located 34 km NNE of Sesostris Bank. There are no emergent cays or islands. Cora Divh has depths of 27.4 to 55 m, and is covered by sand, coral rubble and broken shells. According to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
