Studies of DMS+DMSP and it's relationship with the phytoplanktonic populations in the Eastern Mediterranean Sea
bookPart
The most important volatile sulfur compound in sea water has been found to be dimethylsulfide [DMS] which is mainly produced from B-dimethylsulfoniopropionate [DMSP] by an enzymatic decomposition (21,24). DMSP is contained in marine phytoplank ton possibly as a regulator of cellular osmotic pressure and it is assumed to be excreted directly from the cells as a product ofalgal metabolism (23). DMS constitutes about 90% of the biogenic sulfur emissions from the ocean to the atmosphere and may play an important role in climate regulation. The main purpose ofthe project described herein was to measure the concentrations ofDMS+DMSP in relation to certain phytoplanktonic variables (primary production, species composition, and chlorophyll a) as well as environmental variables (temperature, salinity, nutrients), since there are significant gaps in the literature about these relationships ( 11 ). This is the first report of field measurements ofDMS+DMSP in the Eastern Mediterranean Sea.
