A few recent studies have found evidence of what is known as 'Dark Oxygen': oxygen produced in the absence of light. Will be very interesting to see how this gets used.

Unfortunately, despite rules stating that articles featuring the news/science can be linked, my link was rejected in favour of a poor quality, outdated Wikipedia link so I have added details about the papers:

Sweetman, A.K., Smith, A.J., de Jonge, D.S.W. et al. Evidence of dark oxygen production at the abyssal seafloor. Nat. Geosci. 17, 737–739 (2024).

Rikuan Zheng, Chong Wang, Hongliang Wang, Haibin Qi, Chaomin Sun. 2025. via bioRxiv 2025.03.10.642362

I am not affiliated with any of these people.
