Dark Oxygen
- Recently, scientists reported the discovery of “dark oxygen” in deep Pacific Ocean regions without sunlight.
- Dark oxygen refers to oxygen produced in deep-sea environments where sunlight and photosynthesis are absent.
- The discovery was made near polymetallic nodules on the Pacific Ocean floor at depths around 4,000 metres.
- Researchers observed oxygen levels increasing in sealed deep-sea chambers during experiments.
- Normally, microbes and chemical reactions consume oxygen in deep sediments rather than produce it.
- Scientists propose that electrochemical reactions involving minerals in polymetallic nodules may split seawater into oxygen and hydrogen.
- The study site lies in the Clarion Clipperton Zone, known for ....
