Marine scientists who made headlines last year with their discovery that deep sea nodules could be producing “dark oxygen” are embarking on a three-year research project to explain their findings.

Rocks are generating 'dark oxygen' in an area being explored for deep-sea mining. Over 12,000 feet below the surface of the sea, in a region of the Pacific Ocean known as the Clarion-Clipperton Zone ...

Nearly 4,000 m beneath the Pacific, in water so dark that sunlight has never penetrated, scientists have stumbled on a new way that oxygen can appear where it should not exist. The finding, quickly ...

Scientists will lower instruments to the seafloor to figure out how metallic nodules are generating oxygen in the depths of the Pacific Ocean, an unexpected phenomenon that has fuelled controversy ...

The deep sea, the planet’s most expansive and least understood ecosystem, remains largely unexplored. Yet while the deep sea may seem a dark and distant space, events underwater directly impact our ...
