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 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.

A scientific debate has emerged regarding the possibility of producing 'dark oxygen' without sunlight, through metallic nodules found deep in the ocean. The discovery challenges long-held beliefs ...

The research that gave rise to the dark oxygen discovery was partly funded by a Canadian deep-sea mining business, The Metals Company, that wanted to assess the ecological impact of such exploration.

It's long been thought that photosynthesis was basically the only way that oxygen is naturally generated on Earth (some bacteria can also produce oxygen by breaking down nitrates). But a new study has ...

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.

The Metals Co., a Vancouver-based deep-sea mining exploration company that partially funded the research and is at the forefront of efforts to harvest the nodules in the Clarion-Clipperton Zone ...

The deep sea is home to “dark oxygen” Nodules on the seabed, rather than photosynthesis, are the source of the gas ...

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.
