Cape Verde Rise
The Cape Verde Rise is an oceanic feature that includes the Cape Verde Islands and the areas north and east of the islands and west of the African Continental Shelf as well as Mauritania and Senegal. Geography The rise are bounded by the Canary Basin to the north and the Cape Verde Basin to the south. Numerous seamounts are located in the rise including the Cape Verde (or Cabo Verde) (Latin: sometimes as ''Extracapitis'' being off the cape), Cadamosto, Boa Vista, Nola and Senghor. The third and fourth are named after explorers of Cape Verde, the other, the founding father of Senegal. The highest point is 2,220 meters below sea level and the deepest is in the range of over 3,000 meters deep. In the east end of the rise is the Dakar Canyon. It ranges between the 14 and the 22° parallels north and is 900 km long. Near the rise is the westernmost point in Africa, Cap-Vert, northwest of the rise is the Santo Antão Ridge. In the waters above the Cape Verde Rise is the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mid-Atlantic Ridge
The Mid-Atlantic Ridge is a mid-ocean ridge (a divergent or constructive plate boundary) located along the floor of the Atlantic Ocean, and part of the longest mountain range in the world. In the North Atlantic, the ridge separates the North American from the Eurasian Plate and the African Plate, north and south of the Azores Triple Junction respectively. In the South Atlantic, it separates the African and South American plates. The ridge extends from a junction with the Gakkel Ridge (Mid-Arctic Ridge) northeast of Greenland southward to the Bouvet Triple Junction in the South Atlantic. Although the Mid-Atlantic Ridge is mostly an underwater feature, portions of it have enough elevation to extend above sea level, for example in Iceland. The ridge has an average spreading rate of about per year. Discovery A ridge under the northern Atlantic Ocean was first inferred by Matthew Fontaine Maury in 1853, based on soundings by the USS ''Dolphin''. The existence of the ridge and its ...

Brava, Cape Verde
Brava (Portuguese for "wild" or "brave") is an island in Cape Verde, in the Sotavento group. At , it is the smallest inhabited island of the Cape Verde archipelago, but at the same time the greenest. First settled in the early 16th century, its population grew after Mount Fogo on neighbouring Fogo erupted in 1680. For more than a century, its main industry was whaling, but the island economy is now primarily agricultural. History Brava was discovered in 1462 by the Portuguese explorer Diogo Afonso.Valor simbólico do centro histórico da Praia Lourenço Conceição Gomes, Universidade Portucalense, 2008, p. 97 There is no evidence of human presence on the Cape Verde islands before the arrival of the Portuguese. Around 1620 the population of Brava started with the arrival of settlers from |

Kimmeridgian
In the geologic timescale, the Kimmeridgian is an age in the Late Jurassic Epoch and a stage in the Upper Jurassic Series. It spans the time between 157.3 ± 1.0 Ma and 152.1 ± 0.9 Ma (million years ago). The Kimmeridgian follows the Oxfordian and precedes the Tithonian. Stratigraphic definition The Kimmeridgian Stage takes its name from the village of Kimmeridge on the Dorset coast, England. The name was introduced into the literature by French geologist Alcide d'Orbigny in 1842. The Kimmeridge Clay Formation takes its name from the same type location (although this formation extends from the Kimmeridgian stage of the Upper Jurassic into the Lower Cretaceous). It is the source for about 95% of the petroleum in the North Sea. Historically, the term Kimmeridgian has been used in two different ways. The base of the interval is the same but the top was defined by British stratigraphers as the base of the Portlandian (''sensu anglico'') whereas in France the top was defined as t ...

Ocean Drilling Program
The Ocean Drilling Program (ODP) was a multinational effort to explore and study the composition and structure of the Earth's oceanic basins. ODP, which began in 1985, was the successor to the Deep Sea Drilling Project initiated in 1968 by the United States. ODP was an international effort with contributions of Australia, Germany, France, Japan, the United Kingdom and the ESF Consortium for Ocean Drilling (ECOD) including 12 further countries. The program used the drillship ''JOIDES Resolution'' on 110 expeditions (legs) to collect about 2,000 deep sea cores from major geological features located in the ocean basins of the world. Drilling discoveries led to further questions and hypotheses, as well as to new disciplines in earth sciences such as the field of paleoceanography. In 2004 ODP transformed into the Integrated Ocean Drilling Program (IODP).

Deep Sea Drilling Project
The Deep Sea Drilling Project (DSDP) was an ocean drilling project operated from 1968 to 1983. The program was a success, as evidenced by the data and publications that have resulted from it. The data are now hosted by Texas A&M University, although the program was coordinated by the Scripps Institution of Oceanography at the University of California, San Diego. DSDP provided crucial data to support the seafloor spreading hypothesis and helped to prove the theory of plate tectonics. DSDP was the first of three international scientific ocean drilling programs that have operated over more than 40 years. It was followed by the Ocean Drilling Program (ODP) in 1985, the Integrated Ocean Drilling Program in 2004 and the present International Ocean Discovery Program in 2013. History The initial contract between the National Science Foundation (NSF) and the Regents of the University of California was signed on June 24, 1966. This contract initiated the first phase of the DSDP, which wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jacksonville Fracture Zone

Fifteen-Twenty Fracture Zone
The Fifteen-Twenty or 15°20' Fracture Zone (FTFZ), also known as the Cabo Verde Fracture Zone, is a fracture zone located on the Mid-Atlantic Ridge (MAR) in the central Atlantic Ocean between 14–16°N. It is the current location of the migrating triple junction marking the boundaries between the North American, South American, and Nubian plates. The FTFZ is roughly parallel to the North and South America—Africa spreading direction and has a broad axial valley produced over the last ten million years by the northward-migrating triple junction. Offsetting the MAR by some 175 km, the FTFZ is located on one of the slowest portions of the MAR where the full spreading rate is 25 km/ Myr. Geological setting North and south of the FTFZ the axis of the MAR is near-perpendicular to the spreading direction and the spreading rate is 2.6 mm/yr. The axial valley south of the FTFZ is composed of short axial volcanic ridges separated by 8–18 km-long en echelon deeps, w ...

Kane Fracture Zone
The Kane Fracture Zone is a medium-offset transform fault zone located on the Mid-Atlantic Ridge (MAR). It lies just to the north of the Kane Megamullion, an oceanic core complex that forms the footwall of a long-lived low-angle detachment fault. The Mid-Atlantic Ridge near the Kane Fracture zone (known as the MARK area) has been the focus of detailed scientific investigations, notably Expeditions 106 and 109 of the Ocean Drilling Program, as well as numerous other geological and geophysical studies. The Kane Fracture Zone offsets the MAR left-laterally by at 24°N. Its fossil trace on the western side of the MAR stretches some westward to the 80 Ma isochron (anomaly Anomaly may refer to: Science Natural *Anomaly (natural sciences) ** Atmospheric anomaly ** Geophysical anomaly Medical * Congenital anomaly (birth defect), a disorder present at birth ** Physical anomaly, a deformation of an anatomical struct ... 34).

Canary Current
The Canary Current is a wind-driven surface current that is part of the North Atlantic Gyre. This eastern boundary current branches south from the North Atlantic Current and flows southwest about as far as Senegal where it turns west and later joins the Atlantic North Equatorial Current. The current is named after the Canary Islands. The archipelago partially blocks the flow of the Canary Current (Gyory, 2007). This wide and slow moving current is thought to have been exploited in the early Phoenician navigation and settlement along the coast of western Morocco. The ancient Phoenicians not only exploited numerous fisheries within this current zone, but also established a factory at Iles Purpuraires off present day Essaouira for extracting a Tyrian purple dye from a marine gastropod murex species. Upwelling A prominent feature of Eastern Boundary Currents is the presence of upwelling. Ekman drift causes offshore transport of surface waters, which are then replaced with deep wate ...
