MEASUREMENT OF DIMETHYL SULFIDE IN THE BO SEA AND GULF OF JIAOZHOU

Measurements of the concentration of dimethyl sulfide (DMS) in surface waters have been carried out in the Bo Sea in March, 1993 and April, 1994. DMS concentrations in the Bo Sea in the end of winter were betwe en 7 and 163 ng/l, 81 ng/l on average. A seasonal variation of DMS con centrations was observed in the Gulf of Jiaozhou by a factor of 4 betw een spring and winter with mean concentrations of 363 ng/l and 408 ng/ l in the spring seasons of 1993 and 1994 and 87 ng/l in the 1993 winte r season. The flux of DMS from the sea to the air also showed a season al variation.
