In order to systematically examine the vertical distribution of chlorophyll a and nutrients, and to provide the original data for marine ecosystem simulation, water quality and marine ecosystem data were collected in four different seasons from October 2007 to September 2008. The sampling site was located at the central point between Dalajia Island and Sangzhou Island. The study examined the vertical distribution and seasonal variation of chlorophyll a and nutrients, and analyzed the correlation between chlorophyll a and dissolved inorganic carbon (DIC), PO4-P, and SiO3- Si. The results showed that the variations of chlorophyll a, DIN, PO4-P and SiO3-Si were 0.50-5.80 mg·L-1, 0.023-0.159 mg·L-1, 1.606-19.69 μg·L-1 and 0.065-1.13 mg·L-1, respectively. The seasonal variations of chlorophyll a were higher in summer, spring, and winter but lower in autumn. SiO3-Si and DIN were similar, which were higher in summer, autumn, and winter, but lower in spring. PO4-P showed a reverse trend, which was the lowest in summer. The impact of DIN and SiO3-Si on chlorophyll a was low in vertical variation. The PO4-P and chlorophyll a showed a positive correlation, indicating that the impact of PO4-P on chlorophyll a was great.
