New deep-sea oxygen source raises mining impact concerns

The Hindu — July 27, 2024, 05:00 AM UTC

Summary: A recent study published in Nature Geoscience reveals an unknown process producing oxygen in the deep ocean, where photosynthesis is impossible. Conducted in the Clarion-Clipperton Zone, the research indicates that polymetallic nodules may generate oxygen by splitting water molecules. This discovery raises concerns about the potential impact of deep-sea mining on marine ecosystems, as many countries, including India, plan to explore these resources.
