Fact check: What is behind the dark oxygen stories?

1. Summary of the results

"Dark oxygen" refers to a groundbreaking scientific discovery where oxygen is produced without photosynthesis at the ocean floor. Scientists found that polymetallic nodules in the Pacific Ocean's Clarion-Clipperton Zone act as natural "geo-batteries," creating oxygen through seawater electrolysis with voltage potentials up to 0.95V ^[1]. This discovery is considered a "scientific bombshell" as it challenges our fundamental understanding of oxygen production on Earth ^[2].

2. Missing context/alternative viewpoints

Several crucial pieces of context are worth noting:

• A $2.4 million research project is currently investigating this phenomenon ^[3], indicating significant scientific interest and investment.
• The discovery has caught NASA's attention for its implications in the search for extraterrestrial life, as it demonstrates oxygen can be generated without sunlight ^[2].
• There are environmental concerns: The Sustainable Ocean Alliance warns that deep-sea mining could disrupt these newly discovered oxygen production processes, potentially causing unknown ecological consequences ^[4].
• The finding has implications for understanding life's origins on Earth and potentially other planets ^[5].

3. Potential misinformation/bias in the original statement

Several factors should be considered when evaluating information about this topic:

• The term "dark oxygen" might be confused with space-related conspiracy theories and myths that often spread through social media and sensationalist reporting ^{[6] [7]}.
• There are competing interests at play:
• Scientific institutions benefit from highlighting the groundbreaking nature of this discovery for funding and recognition ^[3].
• Environmental organizations like the Sustainable Ocean Alliance use the discovery to advocate against deep-sea mining ^[4].
• Space agencies like NASA have interest in the implications for extraterrestrial life detection ^[2].

It's important to note that while this is a legitimate scientific discovery, it should be distinguished from unsubstantiated space-related claims and conspiracy theories that often circulate online ^[6].
