Monthly study was conducted on the net primary productivity and some environmental factors like water temperature, pH, salinity, conductivity, turbidity, light penetration, total suspended solids, total dissolved and alkaline substances, Chl.-a, dissolved oxygen in addition to some Nutrients like NO3, NO2, PO4 and SiO2, were studied in the areas near Umm Qasr Port and near Buoy 17, in addition to the Basra oil port area in the Iraqi coastal waters. The current study showed that the values of primary productivity ranged from 15.9-98.55 Cmg/l, and the pH and alkalinity were within the ranges prevailing in the Iraqi coastal waters and the temperature values were within their annual rates as they ranged from 14-34°C, while the values of the pH and alkalinity were within the ranges prevailing in the Iraqi coastal waters, the recorded values of light penetration were 14-250cm, while the turbidity values in the third station decreased, high values were recorded in the first and second stations and this is the case in the TSS and TDS values as well.
