| Abstract: | The abundance,diurnal variation features of phytoplankton biomass and the horizontal distribution patterns of Chl. a and primary productivity in the Taiwan Strait were investigated during a summer and a winter cruise inAugust 1994 and February 1995, respectively. Results show that the horizontal distribution of phytoplankton biomasswas quite similar to that of productivity.In summer, there was a relatively barren, low priductive region in the centallocation of the northern Taiwan Starit (NTS), and high productive regions were located at the nearshore and to thenorth of Cape Fugui of Taiwan Island; meanwhile, high productivity regions were only located at coastal waters of thesouthern Taiwan Strait (STS). In winter, high productive regions of NTS occurred off northwestern coast of TaiwanIsland, while that of STS was located along the southem edge of Minnan (South Fujian) - Taiwan Bank. Vertical patterns of the diurnal variation of Chl. a indicated that in non-stratified waters, phytoplankton biomass changed in tiedrhythm; as for the stratified waters, the depth at which the highest variation amplitude located located coincided with thedepth where the highest variation frequency occurred. The grazing pressure of zooplankton strongly influenced the diurnal variation of size-fractionated structure of phytoplankton biomass. As a result of our investgitions, we concludethat in the Taiwan Strait, biological porcesses may be more important at smaller scales where behaviors such as verticalmigration and predation may control the phytoplankton production, whereas physical processes may be more importantat larger scales in structuring phytoplankton patchness. |
