Phosphorus speciation in the Scheldt estuary and the belgian coastal zone

Phosphorus speciation was studied in the Scheldt estuary and the Belgian coastal zone from November 2002 to December 2003. Monthly surveys were performed at 10 coastal stations and seasonal campaigns (winter, spring and summer) were conducted in the Scheldt estuary. Weekly to monthly samples were also taken in the upper freshwater reaches of the Scheldt and in tributaries at stations under the tidal influence.Phosphorus was measured as soluble reactive phosphorus (hereafter called PO4), dissolved inorganic phosphorus (DIP), total dissolved phosphorus (TDP), particulate inorganic phosphorus (PI...
