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 ...

Instead of sinking from the surface, some deep-sea oxygen may be created by battery-like nodules that split water into hydrogen and oxygen. Skip to content Subscribe or renew today ...

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.

Researchers discovered the presence of strange "nodules" on the ocean floor at a depth of about 13,000 feet, and they are capable of producing oxygen in total darkness, according to a new paper in ...

"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.

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 ...
