Mystery oxygen source discovered on the sea floor — bewildering scientists
https://www.nature.com/articles/d41586-024-02393-7
Researchers have discovered a surprising new source of oxygen at the bottom of the Pacific Ocean, challenging previous assumptions about oxygen production. Found in the Clarion-Clipperton Zone, the phenomenon is linked to polymetallic nodules that may catalyze the splitting of water molecules. This discovery could have significant implications for understanding deep-sea ecosystems and the origins of life. The oxygen production mechanism remains unknown, prompting further investigation to prevent potential disruptions from deep-sea mining.
