Trend in summer chlorophyll-a concentrations in coastal and open waters of the Baltic, Celtic and Mediterranean Seas and NE Atlantic, 1985-2010

This figure shows stationwise trends in chlorophyll-a 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 statistically significant change, within the years 1985–2010). Numbers in parentheses indicates 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.

Percentage of clasiffied water bodies in less than good ecological status or potential in coastal and transitional waters

Percentage of natural, heavily modified, artificial and unknown status for river, lake, transitional and coastal water bodies

Percentage of transitional (a) and coastal (b) water bodies in poor and good chemical status, by count of water bodies

The graphs illustrate the chemical status of transitional and coastal water bodies as percentage of water bodies in poor and good chemical status, by count of water bodies.

Percentage of classified surface water bodies in different river basin districts (RBDs) holding less than good ecological status or potential, for rivers and lakes (top panel) and for coastal and transitional waters (bottom panel)

The figure shows percentage of the total number of classified water bodies. See the indicator specification for more details.

Proportion of classified water bodies in different RBDs affected by pollution pressures, for rivers and lakes (left panel) and for coastal and transitional waters (right panel)

The percentage is based on total number of classified water bodies. See the indicator specification for more details.

Coastal — coastal floods

Driven by rising sea levels, tidal swings and storm surges, coastal floods are a growing threat to buildings, energy and transport infrastructure, water supplies and human lives. Coastal defences (walls, breakwaters, artificial headlands) are generally designed to withstand sea levels within historical ranges (e.g. ‘once-in-a hundred-years’ floods). Projected changes in the frequency and intensity of coastal floods are a major threat to ecosystems and the population in low-lying coastal areas in northern and western Europe.

Chemical status of transitional and coastal waters per RBD — percentage of water bodies not achieving good chemical status

Conservation status of river and lake habitat types and species, and conservation status of coastal and transitional waters habitat types of European interest

Distribution of ecological status or potential of classified rivers, lakes, coastal and transitional waters, by count of water bodies

Ecological status/potential of and proportion of water bodies affected by pollution and hydromorphological pressures for transitional (left panel (a, b, c)) and coastal (right panel (d, e, f)) water bodies, by sea region
