Scientists have made a groundbreaking discovery in the Pacific Ocean that challenges our understanding of Earth’s history and the origin of life. They have found evidence of oxygen production in the deep, lightless depths of the ocean.
The results of this study published in Nature Chemistry challenge the traditional belief that oxygen on Earth is solely produced through photosynthesis.
Lead by Professor Andrew Sweetman, researchers from the Scottish Association for Marine Science (SAMS) made this discovery while exploring the depths of the Clarion-Clipperton Zone, between Hawaii and Mexico.
Named “dark oxygen,” this mysterious phenomenon occurs at depths where light cannot penetrate. The researchers discovered the potential source of this oxygen production while studying polymetallic nodules on the ocean floor, rich in precious metals used in electronics.
These nodules may have the ability to split seawater into hydrogen and oxygen through seawater electrolysis. This finding has significant implications for deep-sea mining activities and the protection of marine habitats.
Director of SAMS, Professor Nicholas Owens, described this discovery as one of the most exciting in marine science, prompting a reevaluation of the evolution of complex life on Earth.
This alternative source of oxygen production challenges the conventional view that cyanobacteria were the first oxygen producers on Earth. It calls for a reconsideration of how complex life evolved and the importance of protecting deep-sea habitats.
