"…we critique the #methodology that the authors outline and present previously non-disclosed data and metadata directly related to the experiments they present.…The data and #metadata that Sweetman et al. omit significantly alters how one interprets the results and directly undermines their claims…we suggest that the hypothesis that #polymetallicnodules produce oxygen can be wholly rejected…"

Contributions to the discussion of novel detection of dark oxygen production at the abyssal seafloor

📢 Scientists have found a mysterious source of oxygen at the bottom of the Pacific Ocean, far from any sunlight needed for photosynthesis. This phenomenon, discovered in a region rich with polymetallic nodules, suggests an unknown energy source might be splitting water molecules to produce oxygen. https://www.nature.com/articles/d41586-024-02393-7

Mystery oxygen source discovered on the sea floor — bewildering scientists

A chemical reaction could be producing oxygen by splitting water molecules, but its source of energy remains unknown.
