Abstract

Abstract

The spatiotemoral distributions and seasonal variations of phytoplankton chlorophyll biomass and its size structure in the Huanghai(Yellow) Sea Cold Water Mass were studied based on the four cruises during 2006—2007. The results show that the average chlorophyll concentration in the upper 30 m layer is in the order of spring (1.01 mg/m³) greater than summer (0.81 mg/m³) greater than autumn (0.72 mg/m³)greater than winter (0.68 mg/m³). The phytoplankton size structures are significantly different between the area where Chl a concentration is greater than 1 mg/m³and less than 1 mg/m³. In the whole region, smallersized nanophytoplankton and picophytoplankton dominated the biomass (>65%), while the contribution of microphytoplankton was relatively higher in winter and spring cruises. The average size index of phytoplankton is in the order of spring (15.47 μm) greater than winter (11.08 μm) greater than autumn (8.61 μm) greater than summer (6.52 μm). The relationships between the total biomass and the contributions of different size fractions show consistent trend in the four cruises in spite of the contrasting physical and chemical environments. The analysis of the relationships between the environmental factors and the chlorophyll concentrations shows that the growth of phytoplankton is limited by the nutrients availability in summer and by the weak light conditions caused by vertical mixing in winter. Phosphorus limitation and vertical mixing might be collectively responsible for the low chlorophyll level in autumn. The distribution patterns of phytoplankton size structures were mainly determined by their relatively competition advantages in different environments.
