Discovery of Dark Oxygen on the Ocean Floor
Researchers have discovered the production of oxygen 4,000 meters below the sea surface, possibly originating from polymetallic nodules on the ocean floor. These nodules, rich in valuable metals like lithium and copper, may be generating oxygen through a unique reaction, offering a potential source of battery ingredients. Despite the dark conditions inhibiting photosynthesis, the nodules seem to stimulate oxygen production, sparking curiosity about their role in sustaining ecosystems and even the origins of life on Earth.
