Outline of Final Research Achievements

This study regard with oceanic volatile compounds, which largely affect on global environment and atmospheric environment. We established method and system to monitor the flux of the compounds occurring at the interface between seawater and atmosphere by using sequential vaporization and mass spectrometer. Dimethyl sulfide (DMS), which is known as sea salt smell compound, in seawater and atmosphere were analyzed simultaneously every 30 min and we presented that the flux of DMS dynamically changed diurnally.
