摘要 | The gross biological dimethylsulfoniopropionate (DMSP) and dimethylsulfide (DMS) production in surface and bottom waters along the coasts of the northern South China Sea (SCS) were investigated during summer of July-August 2000. In surface water, the averaged concentrations of particulate DMSP (DMSPp) and DMS were 42.60 +/- 31.94 nM and 2.12 +/- 138 nM, respectively. In bottom water, the mean DMSPp and DMS contents were 26.37 +/- 20.83 nM and 2.09 +/- 1.55, respectively. Both DMSPp and DMS contents significantly varied spatially (P < 0.05, n=40), but not vertically (P> 0.05, n=40). The highest DMSPp concentration (100.62 nM) was recorded on the surface of Shenzhen waters, whereas the lowest (4.33 nM) was on the surface of Zhanjiang waters. DMS fluctuated correspondingly; the highest (6.79 nM) and lowest (0.83 nM) values occurred on the surface of Shenzhen water and bottom water of Nan'ao Island (Shantou), respectively. Correlation analysis further revealed that DMS/DMSPp production was not closely related with salinity and chlorophyll a content (P> 0.05, n=40). However, the bottom DMS increased with increasing temperature when it is lower than 28.2 degrees C (r(2)=0.52, P < 0.01, n=13), whereas it decreased as the temperature further increased (r(2)=0.86, P < 0.01, n=8). Moreover, in surface waters, light intensity showed a significant positive effect on DMSPp production (r2=0.37, P < 0.01, n=20), with elevated DMSP concentration under high irradiance. Overall, the sea-to-air fluxes of DMS across the coastal area of the northern SCS in summer were within the range of 0.24-15.07 mu mol m(-2) d(-1), with a mean flux of 2.12 +/- 3.20 smol m(-2) d(-1).
