Abstract: Spatial and temporal variabilities in hydrographical parameters were studied in Talapady lagoon, a tropical coastal lagoon located on the southwest coast of India. The lagoon was influenced by two adjoining water bodies, the Talapady river during the southwest monsoon (June-September) and the Arabian Sea during the rest of the year. Temperature, during this study, varied between 26.18 to 34.50°C, salinity from 0.2 to 18.5 × 10-3, dissolved oxygen from 3.90 to 6.20 ml.1-1, suspended particulate matter from 3.8 to 744.3 mg.1-1 and particulate organic carbon from 0.22 to 3.96 mg.1-1 . The nutrients studied included NH3-N (6.79 - 24.72 μg-at.1-1), NO2- N (0.1-9.8 μg-at.1-1), NO3-N (2.5-16.1 μg-at.1-1) , PO4-P (3.4-6 .5μg-at.1-1), and SiO3-Si (15.3- 132.9 μg-at.1-1). Temporal variations in the parameters studied were quite distinct with most parameters following a trimodal pattern, with peaks during premonsoon, monsoon and postmomsoon.
