Winter oxidized nitrogen (NO2 + NO3) concentrations in European seas in 2010: The map shows the winter oxidized nitrogen concentrations in the European coastal and open waters in 2010. 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 in a regional sea

IIn-shore and off-shore Natura 2000 sites, 2011: A map showing the distribution of marine Natura 2000 sites. The map distinguishes between those marine sites within 12 nautical miles (termed ‘Inshore sites’) and those beyond 12 nautical miles (termed ‘Offshore sites’). It is based upon the ‘end 2011’ Natura 2000 dataset.

Trend in winter orthophosphate concentrations in coastal and open waters of the Baltic, North East Atlantic (Greater North Sea, Celtic Seas, Bay of Biscay), and Mediterranean Sea (Western Mediterranean Sea, Adriatic Sea), 1985 - 2010: The figure shows trend in winter orthophosphate concentrations in coastal and open waters of the Baltic, North East Atlantic (Greater North Sea, Celtic Seas, Bay of Biscay), and Mediterranean Sea (Western Mediterranean Sea, Adriatic Sea) (% of stations showing a statistically significant change within the period 1985-2010). Numbers in parentheses indicate the number of stations included in the analysis for each country. "Open sea" is the total of all off-shore stations (>20km) within a (sub)region.

Trend in winter oxidized nitrogen concentrations in coastal and open waters of the Baltic, North East Atlantic (Greater North Sea, Celtic Seas) and Mediterranean Sea (Adriatic Sea), 1985 - 2010: The figure shows trend in winter oxidized nitrogen (nitrate + nitrite) concentrations in coastal and open waters of the Baltic, North East Atlantic (Greater North Sea, Celtic Seas) and Mediterranean Sea (Adriatic Sea) (% of stations showing a statistically significant change within the period 1985-2010). Numbers in parentheses indicate the number of stations included in the analysis for each country. "Open sea" is the total of all off-shore stations (>20km) within a (sub)region.

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.

Water quality and wastewater treatment — WISE interactive maps updated: A series of maps on water quality, updated with the latest information reported by countries, has been published by the European Environment Agency (EEA). The maps display water quality parameters in various receiving waters across Europe, alongside information on urban wastewater treatment and receiving areas sensitive to eutrophication.

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.
