Dark oxygen - Wikipedia
Dark oxygen production refers to the generation of molecular oxygen (O 2) through processes that do not involve light-dependent oxygenic photosynthesis. The name therefore uses a different sense of 'dark' than that used in the phrase " biological dark matter " (for example) which indicates obscurity to scientific assessment rather than the ...
