海洋在线监测浮标在赤潮监测中的应用研究

Abstract

Abstract:

We analyzed the marine online monitoring buoy data of Qinzhou Bay in May 2016 to identify the trend in the real-time monitoring data during the Akashiwo sanguinea red tide. Results showed that the outbreak and disappearance of red tide were affected by hydrological and meteorological factors. After the cold surge, the weather condition turned to reduced wind, temperature increased rapidly, especially the temperature showed a small difference between day and night. During such change of weather, attention should have paid to online monitoring buoy. The contents of pH, DO and chlorophyll were higher than their normal ranges, and there existed obvious diurnal variation during the outbreak of red tide. The contents of pH, DO and chlorophyll had significant positive correlations. When the trend of real-time monitoring data showed that pH, DO and chlorophyll had strong fluctuations in a clear linkage and the values increased rapidly above their normal ranges, early warning of red tide should be issued and field investigation can be started. Real-time monitoring of pH, DO and chlorophyll as environmental factors can provide a scientific reference for predicting red tide.
