Topics: Water and marine environment

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.

Additional information

Selected stations must have at least data in the period from 2007 to present and at least 5 years data in all. "Open sea" is the total of all off-shore stations (>20km) within a (sub)region.

Note that the open sea stations around Faroe Islands are included under Celtic Seas.
