  • a Temperature (Temp), salinity (Sal), DO, pH, turbidity, and Chl a content were measured with a YSI 6600 Sonde; TOC and TC were measured with a TOC machine; and TN, nitrate, ammonium, and TP were measured with a nutrient analyzer. The data presented are means ± 1 standard deviations of 3 measurements. One-way ANOVA detected significant differences (P < 0.05) in all parameters except NO3 and TP among sites. NTU, nephelometric turbidity units.
