Abstract
    Statistical analysis of nutrient data obtained during 8 years of monitoring indicated strong seasonal and spatial variability, with highest concentrations in winter and significantly higher concentrations (on average >2 times higher) in the salinity zone S < 33 than in the salinity zone S = 33. In the North Sea ammonium concentrations significantly decreased from 1995 on (47% in zone S < 33 and 64% in zone S = 33), while for nitrate no significant decrease was observed in the zone S = 33. Despite a drastic reduction (50%) in the riverine inputs of phosphorus to the North Sea during the last decade, phosphate concentrations decreased only slightly in the zone S < 33 (<20%). This observation was somewhat similar to what happened with nitrate. Phosphate concentrations were generally low (mean: 0.75 µM; maximum: 2.4 µM) compared to the other dissolved nutrients. Mean nitrate concentrations were about 18 µM but some extreme concentrations, up to 140 µM were observed. Finally, the dissolved organic nitrogen (DON) content represented a major fraction of the total dissolved nitrogen (TDN) (median of 72% for all data), especially in the zone S = 33, but no significant spatial differences in the DON concentrations were found in the Belgian area of the North Sea.
