Project Abstract

Anthropogenically induced loadings of inorganic nutrients in estuarine and coastal systems globally have lead to the increased frequency in eutrophication symptoms, and can result in implications for higher trophic levels, including fisheries and aquaculture. The implementation of the Waste Water Treatment Directive (CEC1991a) and the Nitrates Directive (CEC 1991b), resulted in the continuous monitoring programmes nationally since the 1990s, and allow for a persistent observation of the status of Irish waters. With the introduction of the Water Framework Directive (2000), a series of physiochemical elements that support �good� ecological status have been identified and all water bodies must comply meet this status by 2015. Improved waste water treatment and measures to reduce diffuse sources of nutrients, chiefly through agricultural practices, have lead to an overall improvement in water quality of coastal and estuarine waters. This project aims to undertake a detailed analysis and interpretation of the accumulated historical monitoring data (nutrients, dissolved oxygen, chlorophyll a, physical and environmental parameters) which would allow for an increased understanding of the functioning of coastal systems in the context of past and current mitigating water management practises. The expected outcomes would also inform future management decisions in the context of European Directives.
