Galapagos Rift

node · earth

A spreading centre in the eastern equatorial Pacific, north-east of the Galapagos Islands, where in February 1977 the submersible Alvin - operating from R/V Knorr on a US National Science Foundation expedition - made the first direct observation of deep-sea hydrothermal venting and of the dense clam, mussel and tube-worm communities around it. The coordinate given is an indicative point on an extended spreading axis, not a vent-field position.
