Analysis on Distribution Trends of Affecting Red Tide Factors in the Beibu Gulf Inshore

Abstract:

Analysis on distribution trends of affecting red tide factors in the Beibu Gulf inshore based on data were monitored by automatic water quality monitoring network in 2011 and 2013, providing the scientific basis for preventing disasters and reducing damages of the red tide. Results showed that, average water temperature of Beibu Gulf are maintained in 21.5 °C ~27 °C in two years, the same station maximum temperature difference is 2.72 °C, and is gradually increased since West to East and rose yearly; pH are maintained in 7.8~8.3, are partial alkaline and relative compared stable, then pH of enclosed sea are below offshore waters, which in pH interval of red tide easy outbreak, existing high risk. DO concentration are between 6.3~7.7mg/L, does not have the foundation of extensive outbreak red tides. Lower percentage of DO in enclosed sea and with less material flux in offshore waters, so enclosed sea are high-incidence areas. Chlorophyll concentration in 2013 are almost lower than 2011, and smaller fluctuations. The environmental capacity of the waters in the Beibu Gulf is getting saturated; therefore, it should closely monitor water temperature, pH, and DO and chlorophyll concentration for predicting red tide.
