A Nutrient-Phytoplankton-Zooplankton-Detritus (NPZD) type of model is developed, and coupled to a three-dimensional ocean circulation model (POM) to simulate the annual cycle of the biogenic elements in a marine ecosystem. The impact of petroleum hydrocarbons and suspended solids are also examined. A series of numerical experiments are conducted to investigate how the marine ecosystem responds to the concentration variation of petroleum hydrocarbons and suspended solids in the sea waters. It is found that as the concentration of suspended solids increases, the diatom bloom occurs for a long time, and meanwhile the dinoflagellate bloom is significantly weakened. As a consequence, the total phytoplankton biomass decreases and the nutrient concentration increase in the water column. Contrary to the SS situation, as the concentration of petroleum hydrocarbons changes, the algae biomass and the nutrient concentration don’t show the obvious differences in the water column.
