Indicator Assessment Nutrients in transitional, coastal and marine waters (CSI 021) - Assessment published Mar 2013
In 2010, the highest concentrations of oxidized nitrogen were found in the Baltic Sea, in the Gulf of Riga and Kiel Bay, and in Belgian, Dutch and German coastal waters in the Greater North Sea. Reported stations in the Northern Spanish and Croatian coastal waters also showed high concentration levels. The highest orthophosphate concentrations were found in the Baltic Sea, in the Gulf of Riga and Kiel Bay, and in Irish, Belgian, Dutch and German coastal waters in the Greater North Sea. Coastal stations along Northern Spain and Southern France also showed high concentration levels. Between 1985 and 2010, overall nutrient concentrations have been either stable or decreasing in stations reported to the EEA in the Greater North Sea, Celtic Seas and in the Baltic Sea. However, this decrease has been more pronounced for nitrogen. Assessments for the overall Mediterranean and Black Sea regions were not possible, data only being available for stations in France and Croatia.  For oxidized nitrogen concentrations, 14% of all the reported stations showed decreasing trends, whereas only 2% showed increasing trends. Decreases were most evident in the Baltic Sea (coastal waters of Germany, Denmark, Sweden and Finland, and open waters) and in southern part of the coast of the Greater North Sea. Increasing trends were mainly found in Croatian coastal stations.  For orthophosphate concentrations, 10% of all the reported stations showed a decrease. This was most evident in coastal and open water stations in the Greater North Sea, and in coastal stations in the Baltic Sea. Increasing orthophosphate trends, observed in 6% of the reported stations, were mainly detected in Irish, Danish and Finnish coastal waters (Gulf of Finland and Gulf of Bothnia) and in open waters of the Baltic Proper.

Figure Observed change in chlorophyll-a concentrations in coastal and open waters of the Baltic, North East Atlantic and Mediterranean Sea, 1985-2010
The map shows stations with a statistically significant decrease (green), increase (red) or no trend (yellow) within the period 1985-2010. Selected stations must have at least data in the period from 2007 to present and at least 5 years data in all. Note that the open sea stations around Faroe Islands are included under Celtic Seas.

Figure Orthophosphate concentrations in European seas
The map shows the winter orthophosphate concentrations in the European coastal and open waters in 2012. The class boundaries “high” (red), “moderate” (orange) and “low” (yellow) concentration are determined by the 80/20 percentiles of the data set for the years 2007-2012 in each regional sea.
