dc.description.abstractTotal organic nitrogen (TON) and dissolved organic phosphorus (DOP) in the coastal and estuarine waters of Goa, India varied from 0.6 to 47.1 mu g-at N 1-1 and 0.12 to 3.49 mu g-at P l-1 respectively. The chlorophyll content of these waters fluctuated from 0.3 to 11.3 mg m-3. The increase in TON and DOP in June and October coincided with the chlorophyll peak, there-by suggesting that these two are derived from planktonic activity. The low values of concentration ratio and assimilation ratio (NO3 -: PO4 3-) suggested that inorganic nutrients were deficient in these waters. However, the percentage of TON and DOP in total nitrogen and total dissolved phosphorus varied from 50.7 to 96.6% and 15.3 to 74.6% respectively, during the post and premonsoon months, when the production remained high. A large portion of TON and DON in the coastal and estuarine waters of Goa might serve as an efficient nutrient supplement for the phytoplankton at times of nitrate deficiency
