Abstract/Artist Statement
Algal productivity in the Stockton Deep Water Ship Channel and San Joaquin River was investigated through the use of bench-scale laboratory experiments. Dissolved oxygen, pH, and chlorophyll a measurements were used to quantify productivity. A light incubation chamber was . constructed to facilitate the quantification of productivity and respiration of algae at various light intensities. Variability in the results could be attributed to time of day, seasonal conditions, and tidal cycles. A photosynthesis-irrad.iance curve was generated to estimate productivity as a function of light intensity. Estimates of respiration ranged from 3.1 to 5.9 [(mg 02/L)(mg Chi a/L)-1h-1]. These results will be incorporated into a comprehensive water quality model of the San Joaquin River.
