||P.32 left column 4th paragraph: "Since the freshwater input to this river is relatively low compared to its volume, the water residence time is long. Highest inputs of freshwater occur in March and April and lowest inputs are between August and September (Cooper et al. 1988). During the summer period the average water residence time is ~100 d. The water is nutrient-rich with NO3 concentrations usually >50µM and PO4 concentrations varying seasonally between 0.1 and 1µM (primary source)."
