DARK OXYGEN
Dark oxygen is a term used to describe molecular oxygen (O2 ) produced in the depths of oceans, where sunlight cannot penetrate.
This is in contrast to the oxygen produced at the ocean’s surface through photosynthesis. (in presence of light)
HOW IS IT PRODUCED?
Scientists believe that polymetallic nodules, which are lumps of iron, manganese hydroxides, and rock found on the ocean floor, might be responsible for producing dark oxygen.
HOW CAN POLYMETALLIC NODULES PRODUCE OXYGEN?
These nodules seem to have the ability to transport electric charges that split water molecules,(H2O) releasing oxygen in a process similar to electrolysis.
SIGNIFICANCE OF THE DISCOVERY
The discovery of dark oxygen is a groundbreaking finding as:
- It challenges our previous understanding of oxygen production on Earth.
- It opens up new avenues for research into the oxygen cycle.
- The potential for life in extreme environments, and
- The possibility of finding oxygen on other planets.
