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.
