Fig. 20.6. Three dimensional plot of the distribution of nitrate concentration found at the minimum
temperature
Comparing the distributions of oxygen and nitrate with a minimum temperature
trend, it can be seen that these two parameters are not good chemical tracers of the
mixing processes, particularly in the case of nitrate. In fact, chemical gradients are less
