SUMMARY.1 Nitrate tended to be low in the estuarine region compared with the freshwater stretches and seasonally was low in October. Nitrite broadly showed patterns similar to NO 3 but at lower values. 2 Reactive phosphate and silicate tended to be much higher in fresh compared with saline stretches and was high in January. 3 These changes are broadly interpreted in relation to river discharge and the seasonality of phytoplankton although other, and as yet unstudied, causes will probably be found to be involved.
