Phytoplankton seasonality patterns in eutrophic marine coastal waters

Abstract

Phytoplankton seasonality patterns were examined in an inshore station fertilized continuously by domestic sewage. Data of certain physical (temperature), chemical (P-PO4, N-NO3, and Si-SiO2 concentrations), and phytoplanktonic (chl a, total cell, diatom, and dinoflagellate concentrations) parameters were analyzed by time series analysis. The phytoplanktonic and chemical parameters exhibited significant seasonal variability - in spite of the constant fertilization of the water - associated with the seasonal variability of temperature.
