Unveiling Dark Oxygen
Researchers led by Andrew Sweetman discovered "dark oxygen" production on the 's seabed, challenging the belief that oxygen generation requires sunlight and photosynthesis.
The phenomenon occurs through electrolysis caused by metallic nodules rich in nickel, cobalt, and manganese, splitting seawater into hydrogen and oxygen in complete darkness.
Implications and Future Research
This discovery prompts a reevaluation of theories regarding the origins of life on Earth, suggesting oxygen production might have started in the ocean's depths rather than through surface photosynthesis.
A $2.7 million research project, funded by , aims to explore dark oxygen further, examining its effects on deep-sea ecosystems and potential implications for life beyond Earth.
