Nutrient retention was studied in the Danish estuary Randers Fjord, using 2 indepen- dent methods: (1) measurement of denitrification and nutrient flux rates across the sediment-water interface, and (2) estimations of mass balance established on the basis of hydrodynamic modelling (MIKE 12). Annual N retention estimated by hydrodynamic modelling was 460 t N yr -1 . Direct mea- surements suggested that 60% of the retained N was denitrified. Despite high area-based denitrifi- cation rates (0.1 to… CONTINUE READING
