Polymetallic nodules may produce oxygen in deep sea

latimes.com — July 27, 2024, 11:00 AM UTC

Summary: New research published in *Nature Geoscience* reveals that polymetallic nodules on the deep ocean floor may produce oxygen, enriching the ecosystem. This finding could impact ongoing negotiations by the International Seabed Authority regarding deep-sea mining. The study, funded by The Metals Co., suggests that these nodules function like batteries, generating oxygen through chemical processes. Critics question the study's methodology and findings, prompting calls for further investigation.
