Abstract* Background Polymetallic nodules in the deep sea of the Clarion Clipperton zone (CCZ) have been implicated in the abiotic production of oxygen during benthic chamber respirometer experiments. The hypothesis, termed “dark oxygen”, was supported with a correlation between average nodule surface area and oxygen production rates, given as a Spearman’s correlation coefficient of ⍴ = 0.664, p = 0.031, n = 11, suggesting that larger polymetallic nodules cause more oxygen production. However, t
