Q&A

• What are the concerns related to deep sea floor mining as a result of these findings?

  There are serious reservations about the findings related to deep sea floor mining due to concerns about oxygen contamination and lack of recovery in mined areas. The impact on oxygen levels and implications for signs of life in the universe are significant.

• What is the hypothesis about the dark oxygen production from nodules?

  Researchers hypothesize that the dark oxygen production from nodules may result from seawater electrolysis driven by the potential difference between metal ions. There is also a correlation between oxygen production rate and nodule size, raising questions. The initial high oxygen production rate plateauing may be related to sediment removal from nodules. This research could challenge deep sea mining as it suggests that polymetallic nodules could be a crucial source of oxygen.

• How is 'dark oxygen' produced from metallic nodules on the sea floor?

  Researchers discovered a potential 'dark oxygen' source from metallic nodules on the sea floor, leading to the generation of small electric currents and the production of oxygen via a natural battery. Experiments showed increasing oxygen levels and measured voltages of up to 0.95 Volts from a single nodule.

• What role do metallic nodules on the sea floor play in the production of oxygen?

  The presence of metallic nodules on the sea floor, particularly in the Clarion-Clipperton Zone, may play a significant role in the groundbreaking process of oxygen production in the deep sea.

• How is oxygen mainly produced in the ocean?

  Oxygen is mainly produced through photosynthesis by plants, algae, and bacteria. Its circulation in the ocean involves diffusion, mixing, and cold water sinking to deeper layers.
