Deep Ocean’s Hidden Secret: The Mystery of ‘Dark Oxygen’ production
In the depths of the Clarion-clipperton zone, a mineral-rich region 4,000 meters below the ocean’s surface, scientists have uncovered a groundbreaking phenomenon: the production of oxygen in complete darkness. This discovery, known as “dark oxygen,” challenges the long-held belief that oxygen can only be generated through sunlight-driven photosynthesis.
The process is driven by mineral-rich rock nodules that release an electrical charge, splitting seawater into oxygen and hydrogen through electrolysis. This natural mechanism has sparked a wave of scientific curiosity, as it suggests that life-sustaining oxygen can be produced in environments devoid of sunlight.
Andrew Sweetman, a professor at the Scottish Marine Science Society and the lead researcher behind this discovery, has embarked on a three-year, $2.7 million project funded by the Nippon Foundation to explore this phenomenon further. Sweetman and his team are using advanced equipment equipped with sensors capable of reaching depths of up to 11,000 meters to investigate the production of dark oxygen.
“Our discovery of dark oxygen was a paradigm shift in our understanding of the deep sea and potential life on Earth,but it raised more questions than answers,” Sweetman said in a press release. He emphasized that the primary goal of the project is to determine whether this phenomenon occurs in other areas of the Clarion-Clipperton region and to decode the mechanisms behind it.

The Clarion-Clipperton Zone is not only a hotspot for dark oxygen production but also a treasure trove of rare minerals found in rock nodules. These nodules, formed over millions of years, are crucial for developing environmentally kind technologies. However, the discovery of dark oxygen has revealed how little we know about this remote region.
Sweetman believes that understanding this phenomenon could have far-reaching implications, even beyond Earth. “This new research will enable us to explore some of these scientific questions,” he said, adding that it could aid space scientists in the search for extraterrestrial life.
Oxygen in unexpected Places
The production of oxygen without sunlight is a rare and puzzling occurrence. However, Sweetman is not the only scientist to encounter oxygen in unexpected places. Emil Ruff, a microbiologist at the Marine Biological Laboratory in Woods hole, Massachusetts, discovered oxygen in freshwater samples buried deep beneath the Canadian prairies.
Ruff and his colleagues reported their findings in a study published in June 2023, revealing that microbes in the water were producing oxygen through a process called double dissociation.These microbes break down nitrites to produce molecular oxygen, which they than use to consume methane for energy.
“nature continues to surprise us,” Ruff explained. “There are a lot of things that people said were impractical, but later turned out to be not so.”
The Broader Implications of Dark Oxygen
The discovery of dark oxygen has opened up new avenues for scientific exploration.Ruff and his team are now investigating water samples from a 3-kilometer-deep mine in South Africa, where water has been trapped in rocks for 1.2 billion years. While scientists already knew that the water contained oxygen,the mechanisms behind its formation remain a mystery.
This phenomenon has also been observed in environments isolated from the Earth’s atmosphere for over 40,000 years.“After 30,000 or 40,000 years (of separation from surface processes), there is no real reason to believe that any oxygen will still be present,” Ruff noted. Yet, nature continues to defy expectations.

The discovery of dark oxygen is a testament to the mysteries that still lie beneath the ocean’s surface. As scientists continue to explore this phenomenon, one thing is clear: the deep sea holds secrets that could reshape our understanding of life on Earth—and beyond.Unlocking the Secrets of Dark Oxygen: A New Frontier in Deep-Sea and Extraterrestrial Research
In the depths of the ocean, where sunlight cannot penetrate, scientists are uncovering a phenomenon that could revolutionize our understanding of life on Earth—and beyond. Known as dark oxygen, this process involves the production of oxygen in the absence of sunlight, a discovery that has sparked excitement among researchers and space agencies alike.
The Science Behind Dark Oxygen
At the heart of this groundbreaking research is radiolysis, a process where radioactivity splits water molecules to produce oxygen. This mechanism, observed in areas where gold and uranium are extracted, offers a potential pathway for oxygen generation without sunlight. However, scientists like Sweetman are exploring another intriguing possibility: the role of microbes.
In a study reminiscent of findings in Canada’s groundwater, researchers are investigating whether microbial interactions could be driving oxygen production on the seafloor. Specifically, the focus is on how hydrogen is released during this process and whether it serves as an energy source for deep-sea microbial communities.
A Collaborative Effort
Chemist Roof is collaborating with Sweetman and other scientists to compare oxygen production methods. Their research suggests that electrolysis of seawater yields more oxygen than microbial or radioactive processes. This insight could have far-reaching implications, not just for Earth’s oceans but for the search for life elsewhere in the universe.
Dark Oxygen and Extraterrestrial Life
NASA has taken a keen interest in dark oxygen research. As Sweetman explains, understanding how oxygen is produced without sunlight could shed light on how life might sustain itself on planets or moons lacking direct sunlight.
the icy moons of Saturn and Jupiter, Enceladus and Europa, are prime targets for this inquiry. NASA plans to conduct experiments to determine the energy required to produce oxygen under the high-pressure conditions found on these moons. These studies could pave the way for future missions aimed at detecting extraterrestrial life.
The Controversy of Deep-Sea Mining
while the scientific community celebrates these discoveries, they are not without controversy. Deep-sea mining companies, eager to extract valuable minerals like cobalt, nickel, copper, lithium, and manganese from seafloor nodules, have raised objections to Sweetman’s research.
Critics argue that deep-sea mining could cause irreversible damage to the ocean’s delicate ecosystems and disrupt carbon storage, exacerbating the climate crisis. Sweetman, however, remains steadfast in his findings. “We are absolutely convinced that this is a real operation taking place at the bottom of the sea,” he asserts, promising to address concerns through peer-reviewed channels.
