Spatial and seasonal distribution of nutrients in the estuarine system of the Pregolya River and the adjacent area of the Baltic Sea
... dynamics were characterized by maxima during the high-water period. Minima were observed in spring and summer during water “blooming” against the background of intense water warming. Spatial distribution was characterized by the highest nitrogen and phosphorus concentrations in the estuarine zone, where the Pregolya River inflow occurs. Episodic pollution exceeding the maximum permissible concentrations for ammonium and nitrite nitrogen was recorded in the eastern section of the Kaliningrad Sea Canal,...
