The seasonal changes in atmospheric temperature, surface water temperature, salinity, dissolved oxygen, pH, turbidity and silt deposition at and in the vicinity of the pearl culture farm located off Veppalodai in the Gulf of Mannar were studied during the period from January, 1974 to December 1978. The surface temperature exhibited a clear double oscillation every year and the atmospheric Temperature which was invariably higher, also registered two maxima and two minima. The salinity was high during the period of the south-west monsoon and low during the north-east monsoon. There was not much variation in ph values and dissolved oxygen content. The water was turbid during most part of the year, with higher dissolved oxygen content. Silt deposition was observed to be high during December. The values of primary production were high in September.
