The concentrations of dimethylsulfide (DMS), dimethylsulfoniopropionate (DMSP) and dissolved methane (CH4) were measured in situ in the Yellow Sea and Bohai Sea from December 2017 to January 2018 to study their distributions, correlations and the air-sea fluxes of DMS and CH4. In addition, the influences of DMSP degradation on the productions of DMS and CH4 were also studied through incubation experiments. The average concentrations of DMS, DMSPd, DMSPp and CH4were (1.39±1.21), (2.87±1.54), (5.59±4.64) and (6.91±2.77) nmol/L in the surface water, respectively. The horizontal distributions of DMS, DMSP, and chlorophyll a (Chl-a) exhibited the same pattern of decreasing from inshore to offshore. The vertical profiles of DMS and DMSP showed that the maximum concentrations both appeared in the upper mixed layer, whereas, the concentration of CH4 increased with depth and reached the maximum at the bottom. Significant correlations were observed between DMS, DMSPp and Chl-a, positive correlations between DMSPd, DMSPp and CH4 were also found (P<0.05). DMSP degradation experiments showed that higher initial concentration of DMSP in seawater, the higher production rate of DMS was. The average air-sea fluxes of DMS and CH4 were estimated to be (2.73±3.18) and (8.14±7.68) μmol/(m2·d) during this investigation, suggesting that the Yellow Sea and Bohai Sea acted as an important source for atmospheric DMS and CH4 in winter.
