During the austral summer of 15 November 1986 to 3 March 1987,bulk aerosol sampling by Andersen high-volume sampler was carried out on board the icebreaker SHIRASE in her relief voyage of the 28th Japanese Antarctic Research Expedition to Syowa Station, Antarctica. The aerosol samples were collected on Toyo Roshi GB100R as impaction surfaces at air flow rates of about 566 l/min. These filters were changed at intervals of four days. The collected samples were analyzed by an ion chromatograph (column : TSK gel IC-Anion-PW) to examine the concentrations of methanesulfonic acid (MSA : CH_3SO_3H) as an oxidation product of dimethyl sulfide (DMS : CH_3SCH_3) in the formation of sulfuric acid aerosols. Methanesulfonate (CH_3SO_3^-) concentrations ranged from the value beyond the detection limit (10 ppb) to 0.067
