Summary:
- Researchers have discovered a new form of oxygen that exists deep below the ocean's surface, in areas with little to no light. This "dark oxygen" is produced by chemical reactions rather than photosynthesis.
- The dark oxygen is found in oxygen minimum zones, areas of the ocean where oxygen levels are extremely low. These zones are important for understanding ocean ecosystems and the global carbon cycle.
- The discovery of dark oxygen provides new insights into the complex chemical processes that occur in the ocean and how life can adapt to extreme environments with limited resources.
