1. Story
2. On the National Science Foundation Galapagos Hydrothermal Expedition, working from R/V Knorr, the submersible Alvin observes shimmering hot fluid issuing from the seafloor surrounded by dense clams, mussels and metre-long white tubes with red plumes. It is the first ecosystem ever found whose energy base is not sunlight.

24. Evidence
25. 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.
26. 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.
