“…Recent studies have reported YSWC as a major nutrient source for sustaining spring bloom (Jin et al, ; Liu, Huang, Huang, et al, ). Additionally, sediment nutrient regeneration (Liu et al, ) and low top‐down controls (Sun, Feng, Zhou, et al, ; Zhang et al, ) might be attributed to the continuous bloom.…”

“…In cold seasons (winter and spring), the SYS is primarily characterized by a southward movement of low‐temperature and ‐salinity, eutrophic YSCCW and a northwestward inshore intrusion of the high‐temperature and ‐salinity, oligotrophic YSWCW (Chen, ; Su & Yuan, ). Because of improved irradiance, water stability, and nutrient enrichment, phytoplankton blooms in spring, which has attracted widespread interest (Liu et al, ; Liu, Chiang, et al, ; Tang et al, , and references therein; Xuan et al, ; Zhang et al, ). In warm seasons (summer and autumn), the SYS is characterized by YSBCW, YSCCW, and the northeastward expansion of the fresh, nutrient‐rich CDW (Chen, ; Su & Yuan, ).…”

“…Flow cytometry (Le et al, ; Liu, Chiang, et al, ), size‐fractionated chlorophyll‐ a (chl‐ a ; Fu et al, ; Zhang et al, ), pigment signature (Li et al, ; Liu, Chiang, et al, ; Liu, Huang, Huang, et al, ), lipid biomarkers (Wu et al, ), and satellite remote‐sensing chl‐ a (He et al, ; Yamaguchi et al, ) have been widely applied in the SYS. These studies have preliminarily indicated that hydrodynamics and nutrients profoundly influenced the phytoplankton biomass and community composition.…”

Regulation of Spatial Changes in Phytoplankton Community by Water Column Stability and Nutrients in the Southern Yellow Sea

The southern Yellow Sea (SYS) shows extensive spatial variations in water masses, particularly YS Warm Current Water (YSWCW) and YS Coastal Current Water in cold and YS Bottom Cold Water (YSBCW) and Changjiang Diluted Water in warm seasons. These hydrographic processes result in significant spatial changes in nutrients, stratification, and turbidity, which may highly regulate phytoplankton distribution in the SYS. Here, we provide high spatial resolution data sets of phytoplankton in the SYS in all seasons during 2011-2012. Diatoms thrived in eutrophic Changjiang Diluted Water and YS Coastal Current Water regions. Notably, benthic/meroplanktonic diatoms, including Paralia sulcata and Rhaphoneis spp., were dominant near the Changjiang Estuary and Subei Shoal. However, cryptophytes and haptophytes were dominant in oligotrophic offshore regions controlled by YSWCW and YSBCW. Phytoplankton abundance and chlorophyll a were considerably lower in the YSWCW and YSBCW than in other regions, and the community composition varied significantly among regions. Algal blooms were observed off the SYS coast in spring and near the Changjiang Estuary in summer, which were characterized by abundant nutrients, low turbidity, and a relatively stable water column. Canonical correspondence analysis demonstrated that stratification in cold and nutrients in warm seasons were most important variables correlated with phytoplankton community. Variation partitioning analysis confirmed that spatial changes in phytoplankton community composition were largely structured by nutrients rather than by physical factors in all seasons except winter. Our findings highlight the significance of water column stability and nutrients associated with water mass variation in shaping spatial changes of phytoplankton community in the SYS.
