Analysis of the impact and causes of Enteromorpha prolifera disaster in the Yellow Sea

Abstract

The Southwest Yellow Sea is close to Chinese mainland and belongs to the coastal temperate shelf area. In the summer of 2008, the world’s largest green tide (mainly Enteromorpha prolifera) event occurred in Qingdao, and every year thereafter, Enteromorpha prolifera disaster events have occurred along the southwest coast of the Yellow Sea. Based on the observation data of Enteromorpha prolifera and the results of previous studies, the influence and causes of Enteromorpha prolifera disaster in the Yellow Sea are analyzed in this paper. It is found that the duration of Enteromorpha prolifera disaster is about 3 months, with significant inter-annual variation characteristics. This helps to provide direct and effective new cognition for the prevention and control of Enteromorpha prolifera from multiple perspectives, and better serve the environmental protection and sustainable development planning of the Yellow Sea.
