1. Story
2. 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.

9. Evidence
10. Direct submersible observation in February 1977 documented hydrothermal venting on the Galapagos Rift and dense associated animal communities including clams, mussels and large tube worms, in permanent darkness.
11. The Galapagos Hydrothermal Expedition, funded by the US National Science Foundation, sailed on R/V Knorr from 8 February 1977; Alvin dives revealed vent communities of giant clams, mussels and metre-long tube worms - the first known ecosystem not based on photosynthesis.
