Researchers found oxygen concentrations rising inside sealed patches of seafloor more than 4,000 meters deep in the Pacific, suggesting a form of “dark oxygen” produced by electrolysis within polymetallic nodules rather than photosynthesis, a discovery with implications for ocean chemistry and debates over deep-sea mining.
A Nature Ecology and Evolution study of the Clarion-Clipperton Zone found 4,350 seabed wildlife specimens; about 3,826 matched 788 known species, revealing over 500 potential new species and underscoring the ocean floor's hidden biodiversity as deep-sea mining expands, with researchers noting a 37% decline near mining paths and emphasizing the need to predict biodiversity loss and guide more responsible extraction.
Scientists plan two 11-km-deep landers in the Clarion-Clipperton Zone to test whether metallic seabed nodules emit oxygen, a controversial claim dubbed 'dark oxygen.' The study, which could reshape ideas about life's origins, will measure seafloor respiration and rule out buoyant air artefacts while contending with mining industry skepticism; results are expected within days of deployment, with broader analyses following the ship’s June return.
A 1979 deep-sea mining experiment in the Pacific's Clarion-Clipperton Zone left lasting scars on the seafloor, with visible damage still evident 44 years later. While some small organisms are beginning to recolonize the area, the recovery of larger, stationary species is slow, raising concerns about the ecological impacts of future large-scale mining operations in this fragile ecosystem.
Researchers have discovered whimsical new marine life, including a bright pink 'Barbie pig' sea cucumber, near the Clarion-Clipperton Zone (CCZ) in the deep sea, which is targeted for seabed mining due to its rich metal reserves. The project aims to develop an ecological census of the region to assess potential impacts of mining activities. The discovery of these new species, such as the 'unicumber' sea pig and the 'Rattail fish,' highlights the need for further research to understand the unique and sparse ecosystem of the CCZ.
