Shifts in limiting nutrients in an estuary caused by mixing and biological activity
limiting nutrients mixing biological activity
2014/4/8
Simple general equations are used to show that when riverine water mixes with seawater, the N : P ratio is a
nonlinear function of salinity. Thus, a shift in the limiting-nutrient status at a particu...
