Abstract
The key feature of the European Water Framework Directive (EU-WFD) is to
measure water quality with respect to ecological categories, i.e. in terms of the
community structure and functioning of natural ecosystems. For the use of
phytoplankton data in comparative ecosystem assessment it is important to
compare similar seasonal phytoplankton stages since phytoplankton runs through
different succession stages throughout the year, all characterised by differences
in biomass and taxonomical composition. In this paper calculable seasonal
markers are suggested from the analysis of a long term data set indicating
important successional stages at different types of coastal waters
