Short summary
Methanol is a climate-active gas and the most abundant oxygenated volatile organic compound in the atmosphere and seawater. This study uniquely combines methanol tracer uptake experiments with 16S rRNA pyrosequencing to show basin-wide microbial methanol uptake throughout the top 200 m of the Atlantic Ocean. These rates showed a positive correlation with the numbers of SAR11 16S rRNA gene sequences, suggesting these numerous bacteria are important sinks for methanol in seawater.
