Benguela Ecoregion
The marine ecoregions of the South African exclusive economic zone are a set of geographically delineated regions of similar ecological characteristics on a fairly broad scale, covering the exclusive economic zone along the South African coast. There were originally five inshore bioregions defined over the continental shelf and four offshore bioregions covering the continental slope and abyssal regions. These bioregions were used for conservation research and planning. They were defined in the South African National Spatial Biodiversity Assessment of 2004. The South African National Spatial Biodiversity Assessment of 2011 amended this to reduce the number of regions to four inshore and two offshore and rename them as ecoregions. The exclusive economic zone An exclusive economic zone (EEZ) is a sea zone prescribed by the United Nations Convention on the Law of the Sea over which a state has special rights regarding the exploration and use of marine resources, including ener ...

Ecoregions Of SA EEZ
An ecoregion (ecological region) or ecozone (ecological zone) is an ecologically and geographically defined area that is smaller than a bioregion, which in turn is smaller than a biogeographic realm. Ecoregions cover relatively large areas of land or water, and contain characteristic, geographically distinct assemblages of natural communities and species. The biodiversity of flora, fauna and ecosystems that characterise an ecoregion tends to be distinct from that of other ecoregions. In theory, biodiversity or conservation ecoregions are relatively large areas of land or water where the probability of encountering different species and communities at any given point remains relatively constant, within an acceptable range of variation (largely undefined at this point). Three caveats are appropriate for all bio-geographic mapping approaches. Firstly, no single bio-geographic framework is optimal for all taxa. Ecoregions reflect the best compromise for as many taxa as possible. Sec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abyssal Zone
The abyssal zone or abyssopelagic zone is a layer of the pelagic zone of the ocean. "Abyss" derives from the Greek word , meaning bottomless. At depths of , this zone remains in perpetual darkness. It covers 83% of the total area of the ocean and 60% of Earth's surface. The abyssal zone has temperatures around through the large majority of its mass. Due to there being no light, there are no plants producing oxygen, which instead primarily comes from ice that had melted long ago from the polar regions. The water along the seafloor of this zone is actually devoid of oxygen, resulting in a death trap for organisms unable to quickly return to the oxygen-enriched water above. This region also contains a much higher concentration of nutrient salts, like nitrogen, phosphorus, and silica, due to the large amount of dead organic material that drifts down from the above ocean zones and decomposes. The water pressure can reach up to 76 megapascal. The area below the abyssal zone is the sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tugela Bank
The Tugela River ( zu, Thukela; af, Tugelarivier) is the largest river in KwaZulu-Natal Province, South Africa. With a total length of , it is one of the most important rivers of the country. The river originates in Mont-aux-Sources of the Drakensberg Mountains at an elevation of almost 11,000 feet This has a very detailed description of the river's course. and plunges 947 metres down the Tugela Falls. The Mont-aux-Sources is also the origin of tributaries of two other major South African rivers, the Orange and the Vaal. From the Drakensberg range, the Tugela follows a route through the KwaZulu-Natal midlands before flowing into the Indian Ocean. The total catchment area is approximately . Land uses in the catchment are mainly rural subsistence farming and commercial forestry. Tributaries The Tugela has a number of tributaries coming off the Drakensberg, the largest being the Buffalo River (KwaZulu-Natal), Mzinyathi ("Buffalo") River (rising near Majuba Hill), but also the L ...

Port Shepstone
Port Shepstone is a large town situated on the mouth of the Mzimkhulu River, the largest river on the KwaZulu-Natal South Coast of South Africa. It is located halfway between Hibberdene and Margate and is positioned 120 km south of Durban. It is the administrative, educational and commercial centre for southern Natal. History Port Shepstone was founded in 1867 when marble was discovered near the Mzimkhulu River mouth and is named after Sir Theophilus Shepstone of the Natal government of the 1880s. William Bazley built a harbour, and the first coaster entered the harbour on May 8, 1880. In 1882 a party of 246 Norwegian immigrants settled in the town and subsequently started to play a major role in the development of the area. Post the opening of the railway to Durban in 1901, the harbour fell into disuse and eventually the river silted up again, making it impossible to use. The 27,000-candela lighthouse still stands at the mouth of the Mzimkulu River. Norwegian settlers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cape St Lucia
A cape is a clothing accessory or a sleeveless outer garment which drapes the wearer's back, arms, and chest, and connects at the neck. History Capes were common in medieval Europe, especially when combined with a hood in the chaperon. They have had periodic returns to fashion - for example, in nineteenth-century Europe. Roman Catholic clergy wear a type of cape known as a ferraiolo, which is worn for formal events outside a ritualistic context. The cope is a liturgical vestment in the form of a cape. Capes are often highly decorated with elaborate embroidery. Capes remain in regular use as rainwear in various military units and police forces, in France for example. A gas cape was a voluminous military garment designed to give rain protection to someone wearing the bulky gas masks used in twentieth-century wars. Rich noblemen and elite warriors of the Aztec Empire would wear a tilmàtli; a Mesoamerican cloak/cape used as a symbol of their upper status. Cloth and clothing wa ...

Agulhas Current
The Agulhas Current () is the western boundary current of the southwest Indian Ocean. It flows south along the east coast of Africa from 27°S to 40°S. It is narrow, swift and strong. It is suggested that it is the largest western boundary current in the world ocean, with an estimated net transport of 70 sverdrups (70 million cubic metres per second), as western boundary currents at comparable latitudes transport less — Brazil Current (16.2 Sv), Gulf Stream (34 Sv), Kuroshio (42 Sv). Physical properties The sources of the Agulhas Current are the East Madagascar Current (25 Sv), the Mozambique Current (5 Sv) and a recirculated part of the south-west Indian subgyre south of Madagascar (35 Sv). The net transport of the Agulhas Current is estimated as 100 Sv. The flow of the Agulhas Current is directed by the topography. The current follows the continental shelf from Maputo to the tip of the Agulhas Bank (250 km south of Cape Agulhas). Here the momentum of the current ...

Mbashe River
Mbhashe River is one of the major rivers in the Eastern Cape Province, South Africa. It flows in a southeastern direction and has a catchment area of 6,030 km. The river drains into the Indian Ocean through an estuary located near the lighthouse at Bashee, south of Mhlanganisweni. After passing under national road N2, the Mbhashe River encounters southwest of Elliotdale and north-east of Dutywa the more rugged terrain of the Wild Coast and suddenly enters into a 64 km long series of violent twists and turns known as the Collywobbles before continuing more sedately towards the Indian Ocean. The Mbhashe river's main tributaries are the Xuka River, Mgwali River, Dutywa River and the Mnyolo River. Presently this river is part of the Mzimvubu to Keiskamma Water Management Area. History In 1554 Portuguese ship São Bento ran aground at the mouth of the Mbhashe River. The ordeal of 322 of its survivors, who walked from there to Lourenço Marques, presently Maputo, ...

Alphard Banks
The Agulhas Bank (, from Portuguese for Cape Agulhas, ''Cabo das Agulhas'', "Cape of Needles") is a broad, shallow part of the southern African continental shelf which extends up to south of Cape Agulhas before falling steeply to the abyssal plain. It is the ocean region where the warm Indian Ocean and the cold Atlantic Ocean meet. This convergence leads to treacherous sailing conditions, accounting for numerous wrecked ships in the area over the years. However, the meeting of the oceans here also fuels the nutrient cycle for marine life, making it one of the best fishing grounds in South Africa. Extent and characteristics South African marine ecoregions from the 2011 classification The Agulhas Bank stretches approximately along the African coast, from off Cape Peninsula (18°E) to Port Alfred (26°E), and up to from it.
