Whose observations first revealed hydrothermal vents on the ocean floor?
Quick Answer
Hydrothermal vents were first discovered in 1977 by scientists using the submersible Alvin, with geologist Jack Corliss among the key researchers. Their observations showed that the deep sea can support thriving ecosystems without sunlight.
The Full Story
Hydrothermal vents were first observed in 1977 during dives by the submersible Alvin near the Galápagos Rift. Jack Corliss and colleagues documented hot, mineral-rich water erupting from the seabed and found communities of tube worms, clams, and microbes living around the vents. The discovery was revolutionary because it showed ecosystems powered by chemical energy rather than sunlight. It also changed ideas about where life might exist beyond Earth.
