Abstract

Abstract

The abundance and distribution characteristics of picophytoplankton in the southern Huanghai Sea were investigated by flow cytometry (FCM) during August 2008. The results show that the average abundance and maximum abundance of photosynthetic picoeukaryotes are 1.9×10³ and 2.4×10⁴ cells/mL respectively, while the average abundance and maximum abundance of Synechococcus are 5.3×10⁴ and 5.1×10⁵ cells/mL respectively.From coastal to central broad waters, the distribution of picophytoplankton varied significantly with the changes of environmental factors.The high abundance of picophytoplankton was observed in coastal and estuarine areas, and much lower abundance was recorded in the central broad waters.The relationships between the abundance of picophytoplankton and the environmental factors were also discussed. And the Huanghai Sea Cold Water Mass and the Changjiang diluted water were identified to be the major factors influencing the distribution of picophytoplankton in the study area.
