Field observation in the upper Gulf of Thailand (UGoT) in March 2009 was conducted to prove the relationship between vertical diffusivity (water turbulence) and chlorophyll-a (Chl-a), addressed by numerical model results of our previous study. Relationships between Chl-a and water properties, including salinity, temperature, density, dissolved oxygen (DO), dissolved inorganic nitrogen (DIN) and phosphorous (DIP), dissolved silicate (DSi) and turbulence, were investigated. Blooming areas did not exactly correspond to the area of freshwater influences and high nutrients, except DSi. Insignificant relationships between Chl-a and environmental parameters were found in the correlation analysis. The correlation line indicated that no relationship is evident in the case of Chl-a and DIN. Proportional relationships seem to happen for Chl-a and DIP, and Chl-a and DSi, while reverse relationships for Chl-a and Kz. Further investigations are required to clarify the occurrence mechanism of red tide in UGoT.
