On May 9, while carrying out a marine ecological environment monitoring mission in the East China Sea, members of the East China Sea Environmental Monitoring Center of the State Oceanic Administration discovered a red tide in the sea area east of Huaniao Island, Zhoushan, Zhejiang, at 30 degrees 50 minutes north latitude and 123 degrees 00 minutes east longitude, affecting an area of about 470 square kilometers. The ship launched emergency red tide monitoring and reported it at the first opportunity. A red tide is an "ecological anomaly" in which one or several kinds of plankton in the ocean, under certain environmental conditions, multiply explosively or gather in high concentrations, causing the seawater to change color and affecting and harming the normal survival of other marine organisms.
