Dimethylsulfide(DMS) measurements in the surface seawater of China eastern coastline were conducted during March 9—10, 1993 in Bohai Sea along the cruise from Dalian to Tianjin and during September 24—25, 1994 in Yellow Sea along the cruise from Shanghai to Qingdao. On the cruise in Bohai Sea DMS concentrations varied from 0.11 to 2.63 nmol/L with an average of 1.31 nmol/L, while DMS flux was estimated to be 0.85 μmol/(m 2·d) with the range of 0.04—3.12 μmol/(m 2·d). On the cruise in Yellow Sea DMS concentrations varied from 0.95 to 7.48 nmol/L with an average of 2.89 nmol/L, and DMS flux was estimated to be 7.94 μmol/(m 2·d) with the range of 0.11—18.88 μmol/(m 2·d). Variations in DMS concentrations along the latitude in Yellow Sea were observed larger than those along the longitude in Bohai Sea. DMS concentrations and fluxes had a similar spatial trend both in Bohai Sea and Yellow Sea with the correlation coefficients of 0.75 and 0.64, respectively.

On the cruise in Bohai Sea DMS concentrations varied from 0.11 to 2.63 nmol / L with an average of 1.31 nmol / L while DMS flux was estimated to be 0.85 μmol / (m 2 · d) with the range of 0.04-3.12 μmol / (m 2 · d) On the cruise in Yellow Sea DMS concentrations varied from 0.95 to 7.48 nmol / L with an average of 2.89 nmol / L, and DMS flux was estimated to be 7.94 μmol / (m 2 · d) with The range of 0.11-18.88 μmol / (m 2 · d).
