Eutrophication assessment in Greek coastal waters

Abstract

An attempt is made to assess eutrophication in Greek coastal waters, since the measurements made to date at a few stations do not suffice. In this paper, for more accurate seasonal variations in the nutrient contents, the water masses and their volumes are taken into account. The Pagassitikos Gulf is given as an example and compared to other polluted areas in the Aegean. The variations in the levels of nutrients are due to differences in the sources, as well as the morphology of the bottom and the circulation of waters. Key words: Eutrophicationnutrients
