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.

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 ...

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 ...

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 ...

Metallic nodules found deep in the sea seem to be producing significant amounts of oxygen by some unknown mechanism, researchers revealed last year. Now, we may have found out how it is happening ...

Delicate ecosystem – 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 ...

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 ...

"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 ...
