Dark oxygen' in depths of Pacific Ocean could force rethink about origins of life
Briefly

In the total darkness of the Pacific Ocean depths, strange potato-shaped metallic lumps produce oxygen similar to AA batteries, challenging traditional beliefs about oxygen production only by living organisms.
Small mineral deposits called polymetallic nodules at 4km depth in the Pacific Ocean are producing oxygen independently, rich in metals vital for batteries and electronics.
Research in the Clarion-Clipperton Zone revealed unexpected oxygen production in complete darkness, sparking implications for deep-sea life and the origins of life on Earth.
The discovery of oxygen production by non-biological means could impact future deep-sea mining activities, calling for a reevaluation of environmental consequences and ecosystem impacts.
