In deep-sea environments devoid of sunlight ... The findings raise the possibility that nodules could have been the source of that oxygen to help life get started, says Sweetman.

Researchers say the polymetallic nodules that mining companies hope to harvest from the deep-ocean seafloor may be a source of oxygen for the ... the future of deep-sea mining.

but the rocks also often serve as the only anchoring point for many delicate deep-sea creatures. Now a new study suggests the nodules are able to produce oxygen about 4,000 m below the ocean’s ...

The results also raise new concerns about potentially mining polymetallic nodules, which could represent a vital source of oxygen for deep-sea ecosystems, Sweetman said. "Through this discovery ...

Rare metals on deep sea and ocean floors miles ... how much oxygen polymetallic nodules produce on a broader scale, but the ability for this oxygen source to support deep-seafloor ecosystems ...

This unexpected source of “dark oxygen,” as it’s called ... such a moratorium is so important for protecting these deep-sea nodules in a comment to the Deep Sea Conservation Coalition ...

This discovery that the nodules may be a source of oxygen for the deep sea has major implications in terms of how life on our planet may have begun. "For aerobic life to begin on the planet ...

adding it was possible that the oxygen detected was "trapped air bubbles" in the measuring instruments. He was also sceptical about deep-sea nodules, some tens of millions of years old ...

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 ...
