Descrição: Five stations were sampled monthly in the Bay of Paranagua during one year cycle (1983-1984) to measure basic environmental parameters, phytoplankton biomass and photosynthesis with the purpose of understanding the principal factors that regulate the phytoplankton growth and distribution throughout the year. Surface temperature varied from 17 to 30 degree C. The yearly average values for salinity, dissolved oxygen and pH ranged from 9.38 to 32.00 ppt, 5.17 to 5.53 ml/l and 7.46 to 8.18, respectively. Average concentrations of total inorganic nitrogen, phosphate and silicate varied from 3.31 to 8.48, 0.38 to 0.97 and 27.68 to 98.36 mu g-at/l, respectively, with increasing concentrations toward the inner bay. Chlorophyll- alpha at the surface varied between 2.86 and 13.99 mg/m super(3) with high concentrations in the inner bay associated with high nutrient contents and lower salinities.
