Parcel Das Paredes
Parcel das Paredes is a large submerged bank in Brazil with an area of about 200 km2. It is a coralline structure located in the Atlantic Ocean off the shore near Caravelas, Bahia State. Geography The ''Parcel das Paredes'' lies about 30 km east of the continental shore. Although the reef is submerged, parts of it lie above water at low tide. It is a dangerous area for navigation, but an excellent fishing and scuba-diving ground. The Abrolhos Archipelago lies 35 km further to the east and this ''Parcel'' is part of the same structure. The maximum tide amplitude in the reef area is approximately 1.7 m. Together with the Timbebas Reef located about 40 km to the north of the ''Parcel das Paredes'', as well as the Sebastiao Gomes Reef, Coroa Vermelha Reef and the Viçosa Reef to the southwest, all these reefs are part of the National Marine Park of Abrolhos (NMPA).

Submerged Bank
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 ...

Placer (geography)
Placer ( pt, parcel or ''pracel'') is a term used by Portuguese and Spanish navigators and cartographers to refer to a certain kind of submerged bank or reef. Commonly the bottom of such a reef is sandy, but there are some where the bottom is muddy or stoney. Although most reefs designated as placer are flat and shallow, exceptionally there are some that do not share those characteristics and are known as ''placer acantilado''. A placer usually provides an anchorage for seagoing vessels. Etymology The word placer derives from the Spanish ''placer'', meaning shoal or alluvial/sand deposit, from ''plassa'' (place) from Medieval Latin ''placea'' (place) the origin word for "place" and "plaza" in English. The word in Spanish is thus derived from placea and refers directly to an alluvial or glacial deposit of sand or gravel. Spanish navigator and explorer Pedro Sarmiento de Gamboa commented that ''placer'' likely originated as a term derived from placer mining in the Antilles, where ...

Reefs Of Brazil
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 d ...

Abrolhos Marine National Park
The Abrolhos Marine National Park ( pt, Parque Nacional Marinho dos Abrolhos ) is a national park that was established in 1983 covering most of the Abrolhos Archipelago area in the state of Bahia, Brazil. Location The park was established on 6 April 1983. It covers about . It became part of the Central Atlantic Forest Ecological Corridor, created in 2002. It is located off the southern coast of the Bahia in the north east of Brazil. The islands are volcanic in origin. There are five islands in the Abrolhos archipelago but only one of them, Siriba, is open to visitors. A trail runs round this island. Ilha Santa Bárbara is outside the park boundary. It is under the jurisdiction of the navy, which maintains a navigation beacon there. The other islands are Ilha Guarita, Ilha Redonda, Ilha Sueste. The park also includes the Parcel dos Abrolhos, where typical coral formations of the region may be seen, and the Timbebas reef opposite the city of Alcobaça. Ecology The waters are ...

Sebastiao Gomes Reef
Sebastian ( pt, Sebastião I ; 20 January 1554 – 4 August 1578) was King of Portugal from 11 June 1557 to 4 August 1578 and the penultimate Portuguese monarch of the House of Aviz. He was the son of João Manuel, Prince of Portugal, and his wife, Joanna of Austria. He was the grandson of King John III of Portugal and Holy Roman Emperor Charles V. He disappeared (presumably killed in action) in the battle of Alcácer Quibir, against the Saadians of Morocco. Sebastian I is often referred to as ''the Desired'' ( Portuguese: ''o Desejado'') or ''the Hidden'' ( Portuguese: ''o Encoberto''), as the Portuguese people longed for his return to end the decline of Portugal that began after his death. He is considered to be the Portuguese example of the King asleep in mountain legend as Portuguese tradition states his return, in a foggy dawn, in Portugal's greatest hour of need. Early life Sebastian was born shortly after eight in the morning of 20 January 1554 (the feast of Sai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The state is home to 7% of the Brazilian population and produces 4.2% of the country's GDP. Name The name of the state derives from the earlier captaincy of Bahia de Todos os Santos, named for Bay of All Saints (' in modern Portuguese), a major feature of its coastline.

Coral
Corals are marine invertebrates within the class Anthozoa of the phylum Cnidaria. They typically form compact colonies of many identical individual polyps. Coral species include the important reef builders that inhabit tropical oceans and secrete calcium carbonate to form a hard skeleton. A coral "group" is a colony of very many genetically identical polyps. Each polyp is a sac-like animal typically only a few millimeters in diameter and a few centimeters in height. A set of tentacles surround a central mouth opening. Each polyp excretes an exoskeleton near the base. Over many generations, the colony thus creates a skeleton characteristic of the species which can measure up to several meters in size. Individual colonies grow by asexual reproduction of polyps. Corals also breed sexually by spawning: polyps of the same species release gametes simultaneously overnight, often around a full moon. Fertilized eggs form planulae, a mobile early form of the coral polyp which, when matu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
