Ocean floor metals create 'dark oxygen,' raising mining concerns

Financial Times — July 22, 2024, 11:00 PM UTC

Summary: New research reveals that ocean floor metals can generate "dark oxygen," discovered over 4,000 meters deep in the Pacific Ocean. This finding, linked to polymetallic nodules rich in nickel, manganese, cobalt, and copper, raises concerns about seabed mining's environmental impact. The study coincides with discussions among government officials in Jamaica regarding deep-sea mining regulations, highlighting the need for further investigation into this phenomenon.
