Mining of rare metals on deep sea and ocean floors miles below the surface could create "dark oxygen" and also cause potentially harmful changes to the marine ecosystem, according to new research.

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 and ...

An international team of scientists has found that oxygen is being produced in complete darkness approximately 4,000 meters (13,100 feet) below the ocean's surface. It was previously thought that only ...

YANCHENG, JIANGSU, CHILE, January 7, 2026 /EINPresswire.com/ -- In the face of increasingly demanding industrial and ...

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 ...
