Abstract

Dimethyl sulphide (DMS), as a volatile organic sulfur compound, plays an important role among the reduced sulphur gases in the atmosphere. DMS emitted from seawater constitutes a significant component of the global sulphur cycle and may affect climate by forming atmospheric aerosols which could form cloud condensation nuclei and thus modify cloud properties. DMS is produced from its major precursor dimethylsulphoniopropionate (DMSP) by complex interactions of phytoplankton and bacterial processes. Dimethyl sulphoxide (DMSO) is the major non-volatile dimethyl sulphur pool in the ocean and plays an important role in the biogeochemical cycle of DMS, although its formation and consumption pathways are poorly understood compared to DMSP.
