Marine scientists who made headlines last year with their discovery that deep sea nodules could be producing “dark oxygen” are embarking on a three-year research project to explain their findings.

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 ...

The discovery of "dark oxygen" raises questions about the origins of life on Earth and the potential impact of deep-sea mining on marine ecosystems. The International Seabed Authority is under ...

Mining activity could negatively affect the seafloor ecosystem, scientists warn. Rare metals on deep sea and ocean floors miles below the surface produce "dark oxygen," and mining these minerals ...

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 ...

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.

“These geobatteries are the basis for a possible explanation of the ocean’s dark oxygen production.” The discovery that abyssal, or deep-sea, nodules are producing oxygen is “an amazing ...
