The influence of ocean acidification on surface seawater DMS, DMSP and DMSO concentrations
Dimethylsulfide (DMS), dimethylsulfoniopropionate (DMSP), and dimethylsulfoxide (DMSO) cycling in the surface ocean has an important impact on the biogenic sulfur loading of the atmosphere. Calcifying phytoplankton, such as the ubiquist coccolithophorids, are import producers of the DMS precursor DM...
