We made contemporaneous measurements of methanol concentration and consumption rates in the northwest Pacific Ocean to constrain the pathways and dynamics of methanol cycling. Methanol was detected in relatively low concentrations (<12–391 nM), likely due to rapid biological turnover. Rates of methanol oxidation to CO2 (0.9–130.5 nmol L−1 day−1) were much higher than those of assimilation into biomass (0.09–6.8 nmol L−1 day−1), suggesting that >89.7% of methanol was utilized as an energy source. Surface water acted as a net methanol sink at most sites, with an average flux of 9 μmol L−1 day−1. Atmospheric deposition accounted for 22.7% of microbial methanol consumption in the mixed layer, illustrating that the atmosphere is less important than internal processes for driving methanol cycling in these pelagic waters.en-UScopyright American Geophysical Union 2023https://perma.cc/K6V9-42JXmethanolpacific oceanconcentrationsmethanol consumptionArticle
