Values are means ± standard deviations among all samples. Parameters measured include salinity, temperature, density, colored dissolved organic matter (CDOM), turbidity, dissolved oxygen (DO), nitrate + nitrite (N+N), total Kjeldahl nitrogen (TKN), total nitrogen (TN), total phosphorus (TP), and chlorophyll a (Chl-a).
