Mining conducted on the floors of deep seas could create "dark oxygen" containing metals that could impact the quality of ...

When researchers discovered "dark oxygen" last year, the news spread around the world, but the biggest challenge to the ...

New documentary about deep-sea mining of rare materials in “Nodules” shows in vivid detail the damage mining creates on ...

Scientists posit that the formation of dark oxygen is an electrochemical process. The polymetallic nodules in the deep sea behave like a geobattery in which they "generate a small electric current ...

The discovery of “dark oxygen”, oxygen produced deep under the surface of the sea, is shining a light on the potential risks of deep-sea mining for metals and minerals.

The research team used deep-sea chambers that land on the seafloor and enclose the seawater, sediment, polymetallic nodules, and living organisms. They then measured how oxygen levels changed in ...

New research suggests that polymetallic nodules found 13,000 feet deep produce “dark oxygen” by electrolyzing water. ... The researchers hypothesize that this could be a source of oxygen for deep-sea ...

The discovery of "dark oxygen" produced on the seafloor challenges our understanding of the ocean's ecosystem and raises concerns about the potential impacts of deep sea mining.

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.

Scientists discovered "dark oxygen" produced by deep-sea polymetallic nodules deep below sea level, redefining our understanding of ocean and early Earth life. Search.

A new study published in the journal Nature Geoscience found evidence of oxygen production near polymetallic nodules located deep in the ocean. Called dark oxygen, this oxygen is being produced ...

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 ...
