Scientists have launched a fresh effort to find out what could be producing oxygen at the bottom of the Pacific Ocean.

Mining of rare metals on deep sea and ocean floors miles below the surface could create "dark oxygen" and also cause potentially harmful changes to the marine ecosystem, according to new research.

Far below the reach of sunlight, in water cold enough to freeze most life in its tracks, scientists have found oxygen being ...

Could lumpy metallic rocks in the deepest, darkest reaches of the ocean be making oxygen in the absence of sunlight? Some scientists think so, but others have challenged the claim that so-called "dark ...

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 ...

A mysterious phenomenon first observed in 2013 aboard a vessel in a remote part of the Pacific Ocean appeared so preposterous, it convinced ocean scientist Andrew Sweetman that his monitoring ...

The Metals Co. is trying to discredit new research that bolsters opponents’ claims that the deep sea is too unknown to mine. Scientists this week unveiled what they say is evidence that rocks rich ...

The existence of a previously unknown source of oxygen would call into question long-held assumptions about the origins of life on Earth.

A team of scientists announced Tuesday they have developed new deep-sea landers specifically to test their contentious discovery that metallic rocks at the bottom of the ocean are producing "dark ...
