Abstract

Abstract: From 1997 to 2018, Phaeocystis globosa caused harmful algal blooms in Chinese coastal waters almost every year. In this study, the spatial and temporal distribution of P . globosa blooms and its influencing factors were discussed. The results showed that 80.6% of the P . globosa blooms happened in the South China Sea and 72.5% happened in the period from November to March of the following year. But in the Yellow Sea, P . globosa blooms might be limited by green tides. Among the influencing factors, temperature might be an important one that affected the spatial and temporal distribution of P . globosa blooms. Furthermore, eutrophication provided material basis and El Nino events might also stimulate the occurrence of P . globosa blooms. This study is helpful to reveal causes and mechanisms of P . globosa blooms and reduce the negative impacts of blooms on ecological environment, economic development and the safety of nuclear power plants. Highlights: 80.6% of P . globosa blooms happened in the SCS and 72.5% happened in the period from November to March of the following year. Water temperature might be the important factor affecting the spatial and temporal distribution of P . globosa blooms. Eutrophication provided rich nutrients for the occurrence of P . globosa blooms. The El Nino events might stimulate the expansion of P . globosa blooms. Green tides caused by Ulva prolifera might limit the occurrence of P . globosa blooms in the Yellow Sea.
