From UPSC perspective, the following things are important :
Prelims level: Dark Oxygen
Why in the News?
Deep-sea researchers have initiated a groundbreaking project to explore dark oxygen, a form of oxygen produced in complete darkness on the ocean floor.
What is Dark Oxygen?
- Dark oxygen refers to oxygen produced at extreme ocean depths without the involvement of photosynthesis.
- This process occurs in total darkness on the ocean floor, challenging the traditional understanding that sunlight is necessary for oxygen generation.
- It was first discovered in 2024 by researchers studying deep-sea environments.
- The strange nodules found at a depth of 13,000 feet act like natural batteries, splitting water molecules into oxygen and hydrogen using electrical charges.
- These nodules function in areas where light does not penetrate, under extreme pressure and low-temperature conditions.
- Occurrence:
-
- Found in specific deep-sea zones, particularly in regions characterized by unique electrochemical activity.
- Occurs in places previously considered incapable of supporting oxygen production.
Features and Significance of Dark Oxygen:
- Unlike traditional oxygen production, dark oxygen does not rely on photosynthesis or sunlight.
- It is driven by electrochemical reactions occurring naturally in the ocean floor.
- Strange nodules on the ocean floor possess an electric charge, enabling them to split water molecules into oxygen and hydrogen.
- The process releases hydrogen, which could potentially serve as an energy source for microbial life in these regions.
PYQ:[2012] Which one of the following sets of elements was primarily responsible for the origin of life on the Earth? (a) Hydrogen, Oxygen, Sodium (b) Carbon, Hydrogen, Nitrogen (c) Oxygen, Calcium, Phosphorus (d) Carbon, Hydrogen, Potassium |
