Abstract

Statement of main outcome: This section presents asatellite-based map of potential eutrophic and oligo-trophic areas in the European Seas for the year 2020,together with time series of potential eutrophicationin the past 23 years (1998–2020) averaged over Exclu-sive Economic Zones (EEZs) of each Europeancountry. The map and time series of potential eutro-phication were generated on the basis of a comparisonof the per-pixel chlorophyll-a data from remote sensingin the reporting year with the corresponding chloro-phyll-a climatological 90th percentile (P90) establishedfor a 20-year baseline (1998–2017). The results showedfew scattered potential eutrophic areas, while extensivecoastal and shelf waters indicate a potential oligo-trophic status. The distributions point to localitiesthat should be on a watch to determine the in situnutrient levels and whether the chlorophyll-a trend issustained into the future. The time series of the poten-tial eutrophication at the EEZ level showed low percen-tages across the area with some remarkable highpotential eutrophic events occurring in the first decadeof the study period, followed by an overall reduction inpotential eutrophication from 2013 onwards. Further-more, for several European countries, the eutrophica-tion indicator at the EEZ level was often nil or neverexceeded 1% of the EEZ area. Results are then com-pared with those from the Sustainable DevelopmentGoal (SDG, set by the United Nations General Assem-bly) 14 global satellite-derived eutrophication indicator(target 14.1).
