dc.description.abstractTropical estuaries are potential contributors of dimethylsulfide (DMS), a climatically relevant volatile sulfur compound and its precursor dimethylsulphoniopropionate (DMSP) In order to understand the distribution of DMS and its consequent fluxes from the intertidal beach of a tropical estuary, we monitored the DMS concentrations and estimated the flux from the surfwater of Dona Paula Bay for a period of one year The probable drivers of variability of this compound were also measured Our results show that the average DMS concentration was highest during the monsoon season (7.64nM) followed by post-monsoon (6.71nM) and premonsoon(1.58nM) Consequently, the estimated sea-air flux of DMS is monsoon > post-monsoon > pre-monsoon at 24.75> 18.93> 2.29 uM m<sup>-2</sup>d<sup>-1</sup> respectively Besides light, temperature affected DMS concentrations irrespective of the season Influence of salinity was restricted to monsoon and was responsible for 26% variation in DMS.Our study highlights the significant contribution of the anti-greenhouse gas, DMS from intertidal beaches especially during monsoon when it exceeds some of the coastal and open ocean measurements reported earlier
