Statistically significant trends of ocean colour intensity 1998–2009

Topics: ,
The figure shows statistically significant trends of ocean colour intensity 1998–2009 at the 95 % confidence level (Mann–Kendall test)



Additional information

This analysis is based on satellite observations of ocean colour which is equivalent to chl-a. A global dataset covering the period 1998-2009 and without regional corrections has been used. This dataset is most accurate in the Mediterranean Sea. In the Black Sea, few in-situ observations are available and the satellite imagery is unverified. In the Baltic Sea high concentrations of humic substances in the sea requires a regional correction of the satellite observations, making the analysis less certian in this area.
