Northeastern Brazil Marine Ecoregion
The Northeastern Brazil marine ecoregion covers the coastal marine environment around the Northeast Region of Brazil. The marine ecoregion extends from the mouth of the ParnaÃba River in the west around the eastern point of the Brazilian mainland and south to the Bay of All Saints. The warm South Equatorial Current feeds warm tropical water into the region from the east. The Northeastern Brazil ecoregion is one of two coastal marine ecoregions (with the Eastern Brazil marine ecoregion) in the Tropical Southwest Atlantic marine province. It is thus part of the Tropical Atlantic realm. Physical setting The ecoregion reaches out into the Atlantic Ocean for 200-250 miles from the coast, with narrowing in the middle where the Fernando de Noronha and Atol das Rocas marine ecoregion extends almost in to the shore. The ecoregion is bounded on the west at the mouth of the Parnaiba River and stretches for 1,000 coastal miles to the southeast, where the ecoregion transitions to th ...

São Francisco River
The São Francisco River (, ) is a large river in Brazil. With a length of , it is the longest river that runs entirely in Brazilian territory, and the fourth longest in South America and overall in Brazil (after the Amazon, the Paraná and the Madeira). It used to be known as the by the indigenous people before colonisation, and is today also known as . The São Francisco originates in the Canastra mountain range in the central-western part of the state of Minas Gerais. It runs generally north in the states of Minas Gerais and Bahia, behind the coastal range, draining an area of over , before turning east to form the border between Bahia on the right bank and the states of Pernambuco and Alagoas on the left one. After that, it forms the boundary between the states of Alagoas and Sergipe and washes into the Atlantic Ocean. In addition to the five states which the São Francisco directly traverses or borders, its drainage basin also includes tributaries from the state of Goià ...

Zona Da Mata
The Zona da Mata (, directly translated to grass zone/grassy zone) is the narrow coastal plain between the Atlantic Ocean and the dry ''agreste'' and ''sertão'' regions in the northeastern Brazilian states of Maranhão, PiauÃ, Rio Grande do Norte, ParaÃba, Pernambuco, Alagoas, Sergipe and Bahia. The ''zona da mata'' consists of a narrow plain, generally about 50 to 100 kilometers wide and very flat and low (below 100 metres in elevation), below the northeastern edge of the Brazilian Highlands. The climate is tropical hot and wet (humid), with most rain coming from the southeasterly winds between April and July. Annual rainfall generally totals between 1300 and 2000 millimetres, with averages in June as high as 300 millimetres. Because the climate and soil of the ''zona da mata'' are excellent for the production of sugar cane, very little of the original Atlantic Rainforest vegetation remains. Most of the major cities of northeastern Brazil, including Recife, Salvador, Maceió ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sardinella Brasiliensis
''Sardinella brasiliensis'', (Brazilian sardinella or orangespot sardine) is a species of ray-finned fish in the genus Sardinella. ''S. brasilensis'' are extremely hard to distinguish from ''Sardinella aurita'' and are combined in most studies and catch estimates. They spawn in coastal areas during late spring and summer. The most dense spawning periods are in December and January. From 1973 to 1990 the catch in Venezuela was down from 228000 tons to 31000 tons. These fish are present in the Western Atlantic (including the Gulf of Mexico, Caribbean, West Indies all the way down to Brazil Distinguishing features The standard length of these sardinella is around 20 cm. ''S. brasiliensis'' is similar to their close relative ''S. aurita'' but ''S. brasiliensis'' have two peak spawning seasons. It is important to differentiate this species from ''S. aurita''. Some of the features that make them unique include the anterior gillrakers (see List of ichthyology terms) which are cur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Artisanal Fishing
Artisanal fishing (or traditional/subsistence fishing) consists of various small-scale, low-technology, low-capital, fishing practices undertaken by individual fishing households (as opposed to commercial fishing). Many of these households are of coastal or island ethnic groups. These households make short (rarely overnight) fishing trips close to the shore. Their produce is usually not processed and is mainly for local consumption. Artisan fishing uses traditional fishing techniques such as rod and tackle, fishing arrows and harpoons, cast nets, and small (if any) traditional fishing boats. For that reason, socio-economic status of artisanal fishing community has become an interest of the authorities in recent years. Artisan fishing may be undertaken for both commercial and subsistence reasons. It contrasts with large-scale modern commercial fishing practices in that it is often less wasteful and less stressful on fish populations than modern industrial fishing. Target 14.b ...

Sverdrup
In oceanography, the sverdrup (symbol: Sv) is a non- SI metric unit of volumetric flow rate, with equal to . It is equivalent to the SI derived unit cubic hectometer per second (symbol: hm3/s or hm3⋅s−1): 1 Sv is equal to 1 hm3/s. It is used almost exclusively in oceanography to measure the volumetric rate of transport of ocean currents. It is named after Harald Sverdrup. One sverdrup is about five times what is carried by the world’s largest river, the Amazon. In the context of ocean currents, a volume of one million cubic meters may be imagined as a "slice" of ocean with dimensions × × (width × length × thickness). At this scale, these units can be more easily compared in terms of width of the current (several km), depth (hundreds of meters), and current speed (as meters per second). Thus, a hypothetical current wide, 500 m (0.5 km) deep, and moving at 2 m/s would be transporting of water. The sverdrup is distinct from the SI sievert unit or th ...

Brazil Current
The Brazil Current is a warm water current that flows south along the Brazilian south coast to the mouth of the RÃo de la Plata. Description This current is caused by diversion of a portion of the Atlantic South Equatorial Current from where that current meets the South American continent. The Brazil Current begins at about 10–15ËšS where the South Equatorial Current (SEC) splits near Cabo de São Roque, Brazil. The current reaches a depth of 700 m and the estimated transport at 12ËšS is 2.5 Sv. The transport increases as the current goes further south with 4 Sv at 15ËšS. On the offshore side of the current an anticyclonic recirculation gyre at about 30ËšS causes an increase of the Brazil Current’s transport. The estimated southward transport at 27ËšS, 31ËšS, 34ËšS, and 36ËšS are 11 Sv, 17 Sv, 22 Sv, and 41 Sv. The total transport can be from 70 to 80 Sv by 36ËšS with half of it being in the recirculation gyre.Zemba, J.C., 1991. "The structure and transport of the Bra ...

North Brazil Current
The North Brazil Current (NBC) is a warm water ocean current that is part of the southwestern North Atlantic Gyre. It begins when the westward moving Atlantic South Equatorial Current splits in half and flows northwestward, following the coastline of north Brazil. It ends at the border of Brazil and Guiana, where it is renamed the Guiana Current. It is predominantly a salt water current, but it does help transport fresh water from the Amazon River northward. Track The current begins around 10°S and 31°W, where the split of the South Equatorial Current becomes apparent. The split is forced once the continental shelf begins, and happens quite abruptly. At this point, the current moves quite quickly at 21-23 Sv. Around 5°S, it merges with a northern branch of the South Equatorial Current (SEC) and increases its volume to 37 Sv, with its peak between 100m and 200m deep. Here, the current is at its maximum extent of about 300 kilometers wide. The current continues to about 7°N ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cape São Roque
Cape São Roque ( Port. ''Cabo de São Roque'') or Cape of Saint Roch, is a cape in the northeastern tip of Brazil. Cape São Roque is located in the municipality of Maxaranguape, 51 km north of Natal, in the state of Rio Grande do Norte in Brazil. Cape São Roque is the "point" on the bend of the Brazilian mainland coast that is closest to the continent of Africa.http://www.terra.com.br/turismo/roteiros/2000/09/29/004.htm The cape was first officially visited by European navigators in 1501, in the 1501–1502 Portuguese mapping expedition led by André Gonçalves and Amerigo Vespucci, who named the spot after the saint of the day, St. Roch Roch (lived c. 1348 – 15/16 August 1376/79 (traditionally c. 1295 – 16 August 1327, also called Rock in English, is a Catholic saint, a confessor whose death is commemorated on 16 August and 9 September in Italy; he is especially invoked a ..., whose feast day is August 16.

South Atlantic Ocean
The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about . It covers approximately 20% of Earth's surface and about 29% of its water surface area. It is known to separate the "Old World" of Africa, Europe and Asia from the "New World" of the Americas in the European perception of the World. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and North and South America to the west. As one component of the interconnected World Ocean, it is connected in the north to the Arctic Ocean, to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south (other definitions describe the Atlantic as extending southward to Antarctica). The Atlantic Ocean is divided in two parts, by the Equatorial Counter Current, with the North(ern) Atlantic Ocean and the South(ern) Atlantic Ocean split at about 8°N.
