Discoverers: John Corliss, Jack Dymond

Overview

Discovery of thriving ecosystems around hydrothermal vents on the deep ocean floor near the Galapagos Rift, sustained by chemosynthesis rather than photosynthesis.

Significance

Revealed that life can thrive without sunlight, powered by chemical energy from Earth's interior, expanding the potential habitats for life in the universe.

Methodology

Deep-sea submersible exploration (DSV Alvin) at 2,500m depth, discovering towering tube worms, giant clams, and bacterial mats around volcanic vents.
