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.
Max. elevation. −750 metres (−2,460 ft) Min. elevation. −900 metres (−3,000 ft) The Lost City Hydrothermal Field, often referred to simply as Lost City, is an area of marine alkaline hydrothermal vents located on the Atlantis Massif at the intersection between the Mid-Atlantic Ridge and the Atlantis Transform Fault, in the Atlantic Ocean.
Project FAMOUS (French-American Mid-Ocean Undersea Study[ 1 ]) was the first-ever marine scientific exploration by manned submersibles of a diverging tectonic plate boundary on a mid-ocean ridge. It took place between 1971 and 1974, with a multi-national team of scientists concentrating numerous underwater surveys on an area of the Mid-Atlantic ...
Charlie-Gibbs Fracture Zone is a system of two parallel fracture zones. It is the most prominent interruption of the Mid-Atlantic Ridge between the Azores and Iceland, with the longest faults in the North Atlantic, and is ecologically an important biosystems boundary. It can be traced over more than 2,000 kilometres (1,200 mi), from north-east ...
The Mid-Atlantic Ridge Ecosystem Project MAR-ECO is an international research project in which scientists from 16 nations take part. Norway, represented by the Institute of Marine Research and the University of Bergen, co-ordinates the project which will enhance our understanding of occurrence, distribution and ecology of animals and animal communities along the Mid-Atlantic Ridge between ...
The Kolbeinsey Ridge is a segment of the Mid-Atlantic Ridge located to the north of Iceland in the Arctic Ocean. It is bounded to the south by the Tjörnes Fracture Zone, which connects the submarine ridge to the on-shore Northern Volcanic Zone rifting center in eastern Iceland. [1] The volcanic islands Kolbeinsey and Grímsey lie along the ...
The Azores–Gibraltar Transform Fault is in the top right corner. The Fifteen-Twenty Fracture Zone (or FTFZ, Cabo Verde Fracture Zone, 1520' Fracture Zone, 15°20' Fracture Zone ), [1] [2] [3] is a fracture zone located on the Mid-Atlantic Ridge (MAR) in the central Atlantic Ocean between 14 and 16°N. It is the current location of the ...
Opening of Central and North Atlantic from 170 Ma to the present. The opening of the North Atlantic Ocean is a geological event that has occurred over millions of years, during which the supercontinent Pangea broke up. As modern-day Europe (Eurasian Plate) and North America (North American Plate) separated during the final breakup of Pangea in ...
