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 ...

On the floor of the ocean, there are small mineral deposits known as polymetallic nodules, which may be as small as ... so that we do not deplete the oxygen source for deep-sea life," noted study ...

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 ...

A scientific debate has emerged regarding the possibility of producing 'dark oxygen' without sunlight, through metallic nodules found ... long campaigned to stop deep sea mining from beginning ...

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 ...
