Eutrophication in marine ecosystems
The following document provides general information for eutrophication in the marine environment such as its definition, factors that promote it, its implications to the structure of the pelagic biota and the environment, and its effect on human through its relation with harmful algal blooms (HABs). Eutrophication according to Steele (1976) is the increase in algae growth that follows a faster delivery of nutrients to the marine environment and the consequences of this. Another definition states that eutrophication is the process by which waters that are enriched with nutrients, especially N and P, promote primary production under favorable conditions (Vollenweider 1981). In relation to harmful algal blooms, there are indications that eutrophication favors them with an indirect effect to human health. The rest of the text presents the areas in the Mediterranean and in Greece that eutrophication phenomena do appear, as well as the environmental targets and indicators related to eutrophication according to the Marine Strategy Framework Directive (2010/477/EU) and the Greek Gov. FEK. (2929/1-11-2012).
Keywords: eutrophication, nutrients, climate change, harmful algal blooms (HABs)
It is expected that each country will produce its own document on the selected issue.
