Title: Marine baseline survey 1990-1991. I : nutrients : draft

The Southern Region Marine baseline survey was introduced in 1990 to determine concentrations of nutrients, metals and organochlorine pesticides in coastal waters. Twenty four stations have been monitored four times per annum since December 1990. This report presents results for nutrients over this period. Concentrations were generally higher in estuaries than in open coast locations, gradients being evident down some estuaries. Concentrations were also higher during winter than in summer. These observations reflect the importance of riverine sources of nutrients and their uptake through biological processes. The discharge of major rivers in Sussex and to the southern Kent coast does not appear to cause significant local increases in nutrient concentrations at open coast locations. There was little evidence of elevated nutrient concentrations, excessive algal blooms or oxygen depletion. Increase monitoring effort in estuaries may be required to enable more rigorous determination of sensitivity in terms of the European Waste Water objective.
