Scientists have discovered a massive hydrogen-rich hydrothermal system beneath the western Pacific seafloor. The system was explored using the crewed submersible Fendouzhe. The system offers a new glimpse into deep-sea serpentinization—a process in which iron- and magnesium-rich rocks chemically react with water to form serpentine minerals and release hydrogen. Scientists from the Institute of Oceanology of the Chinese Academy of Sciences (IOCAS) …
