英文摘要Affected by intense human activities, Bohai Sea, the largest inland sea of China, has being suffered from serious water pollution, e.g., exacerbated water eutrophication, frequent red tide outbreaks, causing major damages to marine ecology/environment, public health, and economy. Based on MODIS data during 2014-2015, the spatial and temporal characteristics of surface layer chlorophyll-a concentration has been analyzed and then, the red tide has been monitored for Bohai Sea. The results showed that surface layer chlorophyll-a concentration was overall higher from May to October, which reached its peak in May. Spatially, chlorophyll-a concentration decreased from the coastal area to the offshore, which was higher in Qinhuangdao offshore area, Laizhou Bay, Bohai Bay and Liaodong Bay. According to the chlorophyll-a concentration threshold of 16 mg/m3 and ERGB composite, the red tide information has been successfully extracted. In the Qinhuangdao offshore area with the frequent occurrence and worst-hit area of red tide in Bohai Sea, red tide happened in May and its dispersion area reached its maximum in late May. The distribution of red tide agreed with the location of two bottom hypoxia zones in Bohai sea, suggesting that red tide outbreaks may play an important role in the formation and development of bottom hypoxia zone. The results for this study will provide scientific foundation for the red tide prediction and control of Bohai Sea.
