Metallic nodules scattered across the seabed in the Indian and Pacific oceans are a source of oxygen for nearby marine life – a finding that could upend our understanding of the deep ocean.

Researchers say the polymetallic nodules that mining companies hope to harvest from the deep-ocean seafloor may be a source of oxygen for the animals, plants and bacteria that live there. This ...

Now a new study suggests the nodules are able to produce oxygen about 4,000 m below the ocean’s surface (Nat. Geosci. 2024, DOI: 10.1038/s41561-024-01480-8). Credit: Camille Bridgewater (2024) ...

The discovery of this deep-sea oxygen, dubbed "dark oxygen," is the first time scientists have ever observed oxygen being generated without the involvement of organisms and challenges what we know ...

Scientists have discovered that metallic minerals on the floor of the ocean, as much as 13,000 feet (3,962 meters) below the surface, can generate oxygen. The oxygen that is made there also seems to ...

Researchers say the polymetallic nodules that mining companies hope to harvest from the deep-ocean seafloor may be a source of oxygen for the animals, plants and bacteria that live there.

Scientists discovered "dark oxygen" produced by deep-sea polymetallic nodules deep below sea level, redefining our understanding of ocean and early Earth life.

Rare metals on deep sea and ocean floors miles below the surface produce "dark oxygen," and mining these minerals could cause potentially harmful changes to the marine ecosystem, according to new ...

Sea-floor nodules raise oxygen levels in the deep ocean, suggesting they may have a valuable role in ecosystems and adding to concerns about the impact of deep-sea mining By Madeleine Cuff 22 July ...

New research suggests that polymetallic nodules on the deep-sea floor may produce oxygen, a conclusion that could have enormous consequences for mining companies. Above, Gerard Barron, chairman ...
