Dark Oxygen Production Discovery
Researchers have discovered a novel form of oxygen production, termed “dark oxygen,” on the deep-ocean floor in the Clarion-Clipperton Zone of the Pacific Ocean, challenging the traditional belief that oxygen is primarily generated by photosynthetic organisms. Published in Nature Geoscience, the study revealed that oxygen levels below 4,000 meters have been steadily rising over a decade. The discovery was confirmed through various electrical tests and sensors. Dark oxygen originates from polymetallic nodules, mineral layers rich in cobalt, nickel, and lithium, which may be crucial for aerobic sea life. This finding expands our understanding of oxygen production, highlighting its significance in lightless environments and the potential environmental impacts of mining these nodules. Further research is needed to explore the ecological and mining implications of this discovery.
