Dark oxygen is produced on the seafloor by a process other than photosynthesis. A new study published in Nature Geoscience in July 2024 suggests it's unclear what causes dark oxygen, but a ...

Chugging quietly away in the dark depths of Earth's ocean floors, a spontaneous chemical reaction is unobtrusively creating ...

Rare metals on deep sea and ocean floors miles below the surface produce "dark oxygen," and mining these minerals could cause potentially harmful changes to the marine ecosystem, according to new ...

Sunlight-photosynthesizing organisms like plants and algae have long been believed to be the Earth's original producers of oxygen. But now, researchers have found evidence of a natural O2 factory ...

Dark oxygen refers to oxygen produced at extreme ocean depths without the involvement of photosynthesis. This process occurs on the deep ocean floor, where light cannot penetrate.

Human waste, mostly plastic, was found in abundance at the deepest part of the Mediterranean called the Calypso Deep, 3.1 ...

It could impact marine life stretching from the tiniest bottom dwellers to apex predators like sharks. Read more at ...

Scientists on the US West Coast say they discovered three previously unknown species of deep-sea spider that could have a rare diet fueled by a common greenhouse gas.

Trace metals such as iron or zinc that are stored in deep-sea sediments are lost forever to phytoplankton on the ocean surface. This is what geochemists believed for a long time about the cycle of ...

In July 2024, the team finally published their findings in Nature Geoscience, calling the phenomenon dark oxygen.It’s unclear what’s causing it — Sweetman is preparing to investigate further next year ...
