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.

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 by Priyanka Runwal July ...

New research shows that potato-sized rocks called polymetallic nodules may be creating the "dark oxygen" of the deep sea. How will this affect current negotiations on the future of the mining ...

The U.S. push to mine international waters for metals defies global efforts to control and protect these fragile ecosystems.

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.

The results also raise new concerns about potentially mining polymetallic nodules, which could represent a vital source of oxygen for deep-sea ecosystems, Sweetman said.

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

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

A spokesperson for the ISA, when asked about the “dark oxygen” research, said the agency is committed to supporting scientific research in the deep-sea marine environment, and any relevant ...
