Since 2007, the world's largest macroalgal blooms have occurred along the coastal area of the Yellow Sea for 6 consecutive years. In 2012, shipboard surveying and satellite remote sensing were used to monitor the whole blooming process. The blooms originated in Rudong sea area of the South Yellow Sea where bloom patches were of dark green and filamentous thalli were the dominant morphology. The scale of the blooms reached its peak size in Rizhao sea area of the North Yellow Sea, and decreased promptly and became insignificant in Qingdao coast where the blooms turned yellow, mostly with air sac blades. Meanwhile, vegetative cells of the green tide algae changed into cytocysts gradually from which germ cells were released as the blooms drifted northward. Additionally, chlorophyll contents and fluorescence activity of free-floating thalli in the North Yellow Sea were both significantly lower than that in the South Yellow Sea. Those studies presented here contributed to increasing our understanding about how the green tide declined gradually in the North Yellow Sea.
自 2007 年以来，世界上最大的大型海藻藻华已连续 6 年出现在黄海沿海地区。2012 年，采用船舶调查和卫星遥感监测整个藻华过程。藻华起源于南黄海的如东海域，那里的藻华斑块呈深绿色，丝状藻体是主要形态。藻华规模在北黄海的日照海域达到峰值，然后迅速减少，在青岛沿岸变得微不足道，藻华呈黄色，主要为气囊叶片。同时，绿潮藻类的营养细胞逐渐变为胞囊，其中生殖细胞在藻华向北漂移的过程中释放出来。此外，北黄海自由漂浮藻体的叶绿素含量和荧光活性均明显低于南黄海。本文的研究有助于增加我们对绿潮在北黄海逐渐减少的认识。
