Indicator Specification Chlorophyll in transitional, coastal and marine waters  The indicator illustrates the geographical distribution and trends in mean summer surface concentrations of chlorophyll-a (micrograms per litre) in the regional seas of Europe. The summer period is defined as: June to September for stations north of latitude 59 degrees in the Baltic Sea (Gulf of Bothnia and Gulf of Finland) May to September for all other stations The following marine regions and subregions are covered, in line with the Marine Strategy Framework Directive (sub)regions:   Regions Subregions Baltic Sea None North-East Atlantic Ocean Greater North Sea Celtic Seas Bay of Biscay and Iberian coast Macaronesian biogeographic region Mediterranean Sea Western Mediterranean Sea Adriatic Sea Ionian Sea and Central Mediterranean Aegean-Levantine Sea Black Sea None

Nutrients in transitional, coastal and marine waters The indicator shows 1) annual winter concentrations (micromol/l); 2) classification of concentration levels (i.e. low, moderate, high) and 3) trends in winter oxidised nitrogen (nitrate + nitrite) and phosphate concentration (micromol/l)in the regional seas of Europe.  Levels and trends of winter concentrations of dissolved inorganic nutrients are used for this indicator, as it is assumed that winter concentrations are not significantly reduced due to uptake by primary producers. The winter period is defined as follows: January, February and March for stations east of longitude 15 degrees (Bornholm) in the Baltic Sea  January and February for all other stations. The used regional and subregional seas of Europe are in line with the geographical regions and sub-regions specified in the Marine Strategy Framework Directive (MSFD).  Other European Seas (Icelandic Sea, The Norwegian Sea, the Barents Sea and the White Sea) are not covered in this indicator due to current lack of data.
