Description Measurement on primary production, phytoplankton biomass, POC and PON were made for a period of ten months at a coastal station and for fourteen months at two estuarine stations in Goa (west coast of India). Irrespective of surface and bottom, chlorophyll a ranged from 0.07- 2.68 mg/m? at the coastal station at off Cabo (Stn 1); 0.01-4.33 mg/m? at Mandovi (Stn 2) and 0.16 to 3.95 mg/m? at Zuari (Stn 3). PP varied from 0.5 - 54.69 mgC/m?/hr at Stn 1, 0.19-67.69 mgC/m?/hr at Stn 2 and 0.17-63.24 mgC/m?/hr at Stn 3. Column productivity ranged from 18.98 to 795.52 mgC/m?/hr (av: 206.21 mgC/m? /hr ) at Stn 1, 1.46 to l45.98 mgC/m?/hr (52.78) at Stn 2 and 6.71 to l35.34 mgC/m?/hr (av: 69.98) at Stn. 3.Column chlorophyll ranged from 4.35 to 36.23 mg/m? (av: 6.19 mg/m?) at Stn 3. Phytoplankton biomass in terms of cell density was high in surface waters at Stn 1 and in bottom waters at Stn 2 and 3. Seasonwise surface PP was high during premonsoon at Stn 2 (av: 50.61 mgC/m?/hr) and at Stn 3 (av: 46.72 mgC/m?/ hr) and post monsoon at Stn 1 (av: 18.68 mgC/m?/hr). Estimated division rate of phytoplankton ranged from 0.12 to 10 (av: 1.8), 0.11 to 5.9 (av:0.9) and 0.15 to 0.63 (av:0.32) per day respectively for Stn 1, 2 and 3. Spatial and temporal difference in surface Chl a and PP between the three stations was found to be significant (P-0.01).
