The maps show trends in annual 25-percentile of oxygen concentrations in near-bottom waters at stations with at least 6 years of observations in the period 1989-2019, by three classes of DO concentrations: <4mg/l (including <2mg/l class); 4-6mg/l and >6mg/l. Only trends for time series ending after 2000 are included. The chart shows the number of time series with increasing, decreasing and no trend in the North-East Atlantic Ocean and Baltic Sea for the three classes of DO concentrations during the same period (1989-2019).
