Fresh out the oven, still warm. Top of the tray.
Summary
The article discusses deep-sea mining in the Clarion-Clipperton Zone (CCZ) of the Pacific Ocean, where a robotic vehicle called Patania II conducted the first industrial-scale mining test in 2021. The piece focuses on the environmental concerns surrounding deep-sea mining, particularly the impact on rare abyssal species and whether ecosystems can recover after mining operations. A new series of research cruises will study these species in areas slated for mining to assess potential ecological damage and recovery prospects.
