Description Environmental parameters such as temperature, salinity, dissolved oxygen, BOD pH, nutrients suspended load and chlorophyll 'a' were estimated in the coastal waters of Mangalore. Four transects, each consisting of four stations extending from old Mangaloe port to Surathkal were monitored biomonthly and different parameters were compared seasonwise. Inorganic phosphate values registered high values at all the transects during September, with a maximum of 2.24 mu mol/l. Nitrite was found to be absent except during January. Low bottom values of dissolved oxygen with corresponding high inorganic phosphate were indicative of monsoonal upwelling along the Mangalore coast during September. This period was characterised by a drop in pH values, though not very significant. Low BOD vaues encountered indicated the absence of any organic pollution in the area.
