Abstract
Data from three anchor stations near the mouth of the Columbia River show that there is a large spatial and temporal variability of salinity, silicate, nitrate, and phosphate during both high and low discharge periods. The respective ratios of these nutrients to salinity reflect the contributions of river effluent and deeper upwelled water. Prediction curves based on simple mixtures of river water or deeper oceanic water with coastal surface water can be used to estimate concentrations of the nonconservative materials. These data demonstrate again that routine measurement of chemical parameters from single oceanographic casts in regions near river mouths does not assure the observer of obtaining values representative in either time or space.
