Frequency of low bottom oxygen concentrations in coastal and marine waters
Assessment made on 01 May 2004
- WEU 015
Policy issue: Is the condition regarding eutrophication of Europe's seas improving?
Generally no trend is observed in the frequency of hypoxia in the North Sea or the Mediterranean Sea during the period 1985-2002. Significant trends are observed at a few stations in the Baltic Sea although with no specific pattern. The most drastic change in the frequency of hypoxia in Danish waters occurred from the 1970s to the 1980s (Ærtebjerg et al. 2002). Many stations had too few data to provide sufficient power in the trend analysis.
