Dimethylsulphide (DMS) is an important marine biogenic gas and can be released into atmosphere through seaair gas exchange. The oxidants of DMS in atmosphere are the main compounds of pristine marine sulphate aerosols and would affect the global climate change finally. Almost all the atmospheric DMS, about 90%, comes from the ocean. The southern ocean, which consists about 20% of the whole ocean area, is one of the largest atmospheric DMS sources. In contrast  with the other oceans, the Southern Ocean appears great spatial and temporal variability of surface seawater DMS. In addition, there are the complex hydrography system, variable sea ice condition and various biologic activities in the Southern Ocean as to make survey and understand DMS as well as its controlling factors most difficult. Moreover, it is significant to integrate the DMS seaice exchange processes and its controlling factors studies. In order to develop survey and research on the seaair DMS exchange and biogeochemistry processes, estimate methods of the seaair DMS fluxes will be reviewed, characteristics of the spatial and temporal distribution of surface seawater DMS will be discussed and the seaair DMS flux in the Southern Ocean will be assessed. Finally, major controlling factors of DMS seaair DMS processes will also be analyzed.
