Daviz Visualization Trend in winter orthophosphate concentrations in coastal and open waters of the Baltic, Mediterranean Sea (Western Mediterranean Sea, Adriatic Sea) and North East Atlantic (Greater North Sea, Celtic Seas, Bay of Biscay)

Figure Chlorophyll-a concentrations in European seas in 2010
The map shows Chlorophyll-a concentrations in European coastal and open seas in 2010. The class boundaries “high”, “moderate” and “low” concentration are determined by the 80/20 percentiles of the data set in each sea (sub)region. The low category refers to values within the lowest 20th percentile and the high category refers to values within the upper 20th percentile of concentrations.

Indicator Assessment Status of marine fish stocks (CSI 032) - Assessment published Sep 2011
Most of the EU commercial catch is currently taken from stocks that are assessed. There is, however, a clear trend from north to south: almost all catches in the north come from assessed stocks, whereas in the south this only happens for around half of the catch.  Of the assessed commercial stocks in the NE Atlantic, about one third is outside safe biological limits. In the Mediterranean, about half of the assessed stocks are fished outside safe biological limits. In the Black Sea no stocks are assessed.

Indicator Assessment Nutrients in transitional, coastal and marine waters (CSI 021) - Assessment published Jul 2011
Decreasing nutrient concentrations were found in the North Sea and in the Baltic Sea. In the Mediterranean and Black Sea, the lack of temporally and spatially comprehensive time series does not allow an overall assessment. In 2008, the highest concentrations of oxidized nitrogen were found in the Gulf of Riga, and in Lithuanian, Swedish, German, Belgian, and Scottish coastal waters. Between 1985 and 2008, 12% of all the stations in the European seas reported to the EEA showed decreasing trends of oxidized nitrogen concentrations. These trends were more evident in the open Baltic Sea and in the Dutch and German coastal waters in the North Sea. In 2008, the highest orthophosphate concentrations were found at Finnish coastal stations in the Gulf of Finland, the Gulf of Riga, German, Belgian, French, and Scottish coastal waters. Between 1985 and 2008, 15% of all the stations in the European seas reported to the EEA showed a decrease in orthophosphate concentrations, mainly because of improved waste water treatment. This decrease was most evident in Norwegian, Lithuanian, Danish, Belgian and Dutch coastal water stations, and in the open waters of the North and Baltic Seas.

Indicator Assessment Chlorophyll in transitional, coastal and marine waters (CSI 023) - Assessment published Jan 2009
The highest summer chlorophyll-a concentrations were observed in coastal areas and estuaries and are at many locations associated with nutrient inputs from major rivers. Of the 413 stations reported to the EEA in 2005 with more than 5 years of observations, decreasing trends in summer chlorophyll-a concentrations were found at 7% of stations, increasing trends were found at 8% of stations, and the majority of stations (85%) indicate no statistically significant change in concentration. The stations with descreasing trends are located either in the Baltic Sea or along the coast of Italy.

Indicator Assessment Chlorophyll in transitional, coastal and marine waters (CSI 023) - Assessment published Jul 2011
In 2008, the highest summer chlorophyll-a concentrations were observed in coastal areas and estuaries where nutrient concentrations are high, namely in the Gulf of Riga, the Gulf of Finland and along the coast of France and Belgium. Although nutrient concentrations in some European sea areas decreased from 1985 to 2008 (see Core Set Indicator 21), these changes were not clearly reflected in chlorophyll-a concentrations: of the 546 stations reported to the EEA the majority of the stations (89%) indicated no statistically significant change. Changes were detected mainly in Finnish, Dutch, Norwegian, Swedish and Italian coastal waters. At the Finnish and Swedish monitoring stations chlorophyll-a concentrations showed both decreasing and increasing trends, whereas in Italy, Netherlands and Norway concentrations were mainly decreasing. An analysis of changes based on satellite imagery show significantly increasing trends of ocean colour (equivalent to chl-a)along the Mediterranean coast, whereas trends are significantly decreasing in large parts of the central Mediterranean and Black Seas. It also shows significantly increasing trends in the Baltic Sea, but here the analysis is less certain.

Most of the commercial catch is taken from stocks that are assessed. There is however a clear trend from north to south, with almost all catch coming from assessed stocks in the north to about  half of the catch in the south. In the Black Sea no stocks are assessed.
