2019–2021年中国近海有毒有害微藻和藻毒素分布数据集

Abstract

China's coastal waters, including the Bohai Sea, the Yellow Sea, the East China Sea and the South China Sea, are rich in marine resources and of strategic importance to the nation’s economic development. However, in recent years, the problem of water safety caused by algae and algal toxins is becoming more and more serious, with the frequency and scale of harmful algal blooms are escalating in China's coastal waters. This dataset collected and organized the survey data of toxic and harmful microalgae and algal toxins in China's coastal waters from 2019 to 2021, containing 3,429 entries of microalgae data, 33,240 entries of microalgae molecular species data, 489 entries of phytoplankton algal toxin data, 76 entries of seawater algal toxin data and 440 entries of economic species algal toxin data. The research teams providing the data ensured the accuracy of the test data through rigorous inter-project and international collation efforts. In order to display the distribution of toxic and harmful microalgae and algal toxins in China's coastal waters, we included 115 microalgae distribution maps and 29 algal toxin distribution maps in the dataset. This dataset can provide data support for studying the spatial and temporal distribution of toxic and harmful microalgae and algal toxins in China's coastal waters, and offers valuable data support for the prevention, warning and control of harmful algal blooms.
