To everyone’s surprise, scientists found that the nodules release “dark oxygen” at 4,000 meters, where sunlight cannot reach. This discovery revolutionizes our understanding of deep-sea ...

In a global first, scientists working in the Clarion-Clipperton Zone in the North Pacific Ocean have found that metallic nodules on the seafloor produce their own oxygen, dubbed "dark oxygen.

The research that gave rise to the dark oxygen discovery was partly funded by a Canadian deep-sea mining business, The Metals Company, that wanted to assess the ecological impact of such exploration.

This unexpected source of “dark oxygen,” as it’s called ... But we now know that there is oxygen produced in the deep sea, where there is no light. I think we therefore need to revisit ...

Potato-size metallic nodules strewn across the Pacific Ocean seafloor produce oxygen in complete darkness and without any help from living organisms, new research reveals. The discovery of this ...

Environmentalists said the presence of dark oxygen showed just how little is known about life at these extreme depths, and supported their case that deep-sea mining posed unacceptable ecological ...

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 ...

"Deep-sea discovery calls into question the origins of life," the Scottish Association for Marine Science said in a press release to accompany the publication of the research. Environmentalists said ...
