[Abstract]:The size-fractionated phytoplankton biomass, and the spatial and temporal variations inabundance of Synechococcus (SYN) and picoeukaryotes (PEUK) were measured in the Taiwan Straitduring three cruises (August 1997, February-March 1998, and August 1998). The results show thatpicophytoplankton and nanophytoplankton dominate the phytoplankton biomass, in average of 38% and40%, respectively. SYN and PEUK varied over time in abundance and carbon biomass, greater in summerthan in winter, in range of (7.70–209.2)×106 and (0.75–15.4)×106 cells/cm2in the abundance, and1.93–52.3 and 1.57–32.4 μgC/cm2 in the carbon biomass, for SYN and PEUK, respectively. Thehorizontal distributions of both groups were diurnal but heterogeneous in abundance, depending on thegroups and layer of depths. Temperature is the key controlling factor for picophytoplankton distribution(especially in winter) in the Strait.
