[Influence of terrestrial nutrient input on biogenic production of dimethylsulfide in Quingdao coastal water].
Nearshore water is one of the most important emission area of dimethylsulfide(DMS), at the same time, nearshore water is highly disturbed by human activities. The objectives of this study were to investigate the DMS concentration of coastal water and try to analyze the factors governing its distribution. Four situ investigations were made in the coastal water of Qingdao, which is located at west coast of Yellow Sea. DMS concentrations of surface water showed a clear seasonal variation with peak values during the summer. Spatial and temporal distributions of DMS in three studied areas(havey polluted area, light polluted area, and clean area) were irregular, but when the concentrations of DMS were moralized to chlorophyll a as a measure of phytoplankton biomass, there was significant difference of DMS/Chl a among the three areas, with the nutrient concentration improved, the DMS/Chl a decreased. And there was the positive relation between transparency and DMS/Chl a, especially in summer.
