Oxygen is one of the most essential elements for not only sustaining life but also its beginning. Most know that photosynthetic organisms like plants, algae and bacteria produce atmospheric oxygen. However, a recent study published in a nature journal detected dark oxygen in the abyssal zone. So, let’s look at this observation which can be a big thing for the different life origin stories.
The Science Behind Dark Oxygen
Dark oxygen is the name given to oxygen from an anonymous source or process present in the Clarion–Clipperton Zone, around 4000m below the sea level. It is believed that the majority of marine oxygen is from the atmosphere. However, the latest studies observed its increasing level, which is contradictory to the theories. So, there may be an unknown process taking place at the bottom of the ocean.
Role Of Dark Oxygen In the Environment
The revelation of dark oxygen is a pivotal step in marine biology as it opens doors for new theories while critical of the existing ones. If there is a way to produce oxygen without chlorophyll, then it would be a huge discovery. Thus, its role in dictating the first life on the planet and giving rise to different creatures is a certainty.
Polymetallic Nodules
The scientists found different metals, such as nickel, cobalt and manganese, in the rock bed. These are collectively called polymetallic nodules, and they are a potential source of oxygen after rusting—the electrolytic process.
Effects On Living Creatures
Dark oxygen is the same atmospheric oxygen, but its origin is different, and it is a phenomenon that needs more attention. Therefore, it does not have any effects apart from sustaining itself below the ocean surface.
Dark Oxygen At Seafloor?
So, what does seafloor dark oxygen tell us about marine life? The answer is yet to be explored, considering that there are a lot of variables at present. Not only that, persistent research should take place so that scientists’ understanding of this brilliant discovery builds towards being resourceful for mankind.
The Future Research
There are many questions about future studies, as they might not be in the same interests as the mining corporations. But it should be done nonetheless, as it answers so many questions that help to understand the origin of life on Earth.
Conclusion
Oxygen, a crucial element for life, has been discovered in the abyssal zone of the ocean, around 4000m below sea level. This discovery could challenge existing theories and provide new insights into the origin of life on Earth. Lastly, the discovery could also reveal the role of polymetallic nodules, but future research is needed to explore this fascinating phenomenon.
