Distribution of biogenic sulphur compounds during and just after the southwest monsoon in the Arabian Sea
The Arabian Sea is characterised by strong seasonal oscillations of biological productivity generated by its monsoonal climate. The southwest monsoon causes reversal in the surface circulation of the Arabian Sea, which generates a seasonal upwelling of nutrient-rich waters along the coast of Oman. C...

The Arabian Sea is characterised by strong seasonal oscillations of biological productivity generated by its monsoonal climate. The southwest monsoon causes reversal in the surface circulation of the Arabian Sea, which generates a seasonal upwelling of nutrient-rich waters along the coast of Oman. Concentrations of biogenic sulphur compounds were measured on a transect from the eutrophic waters off the coast of Oman to the oligotrophic waters of the open Arabian Sea, during the UK NERC Arabesque cruise 27 August-4 October 1994. The concentrations of dimethylsulphide (DMS), dimethylsulphoxide (DMSO) and dimethylsulphoniopropionate (DMSP) were found to be elevated in the eutrophic area due to enhanced biological production. However, this increase in DMS, DMSO and DMSP concentration was not observed until after the southwest monsoon had relaxed, and appeared to correspond to increased concentrations of hexanoyloxyfucoxanthin, an indicator of prymnesiophytes. DMSO concentrations were correlated with those of DMS and DMSP in the near surface waters of the Arabian Sea.
