Sea-floor nodules raise oxygen levels in the deep ocean, suggesting they may have a valuable role in ecosystems and adding to concerns about the impact of deep-sea mining By Madeleine Cuff 22 July ...

Nodules in the deep sea may be a source of ‘dark oxygen’ Millions of years old, potato-sized rocks may be generating electricity that splits seawater and produces O 2 ...

Researchers say the polymetallic nodules that mining companies hope to harvest from the deep-ocean seafloor may be a source of oxygen for the animals, plants and bacteria that live there. This ...

In an unexpected twist, metal-rich nodules found on the seafloor are generating oxygen, new research suggests. This meager but steady supply of the vital gas may help support seafloor ecosystems ...

Researchers say the polymetallic nodules that mining companies hope to harvest from the deep-ocean seafloor may be a source of oxygen for the animals, plants and bacteria that live there.

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

"We need to rethink how to mine these materials, so that we do not deplete the oxygen source for deep-sea life," noted study co-author Franz Geiger, a Professor of Chemistry at Northwestern University ...

Metallic nodules scattered across the seabed in the Indian and Pacific oceans are a source of oxygen for nearby marine life – a finding that could upend our understanding of the deep ocean.

Researchers say the polymetallic nodules that mining companies hope to harvest from the deep-ocean seafloor may be a source of oxygen for the animals, plants and bacteria that live there. This ...

New research suggests that polymetallic nodules on the deep-sea floor may produce oxygen, a conclusion that could have enormous consequences for mining companies. Above, Gerard Barron, chairman ...
