4,000 Meters Below Sea Level, Scientists Have Found the Spectacular 'Dark Oxygen'
Scattered across an abyssal plain known as the Clarion-Clipperton Zone (CCZ) are polymetallic nodules that are a potato-sized prize for mining companies in search of materials needed for humanity's green energy transition.
A new study analyzing these modules reveals that these rocky lumps are capable of producing “dark oxygen” 4,000 meters below sea level where light cannot reach.
While this discovery could upend our understanding of how life started on Earth, the study also complicates negotiations around deep-sea mining regulations as it showcases how little we really know about the ocean’s depths.
