Provenance information | The assessment of the trophic status of estuarine and coastal waters around Ireland is mainly based on the analysis of data collected by the EPA between 2010-2012. Additional data from the Marine Institute’s annual winter nutrient monitoring in the western Irish Sea and eastern Celtic Sea are also included. A Trophic Status Assessment Scheme (TSAS) for the classification of these waters was developed. Both dissolved inorganic nitrogen (DIN) and ortho-phosphate (MRP) levels are assessed in summer and winter, chlorophyll data are assessed using a median and 90 percentile approach and oxygen conditions are assessed both in respect of deoxygenation and supersaturation. The Water bodies are then assigned a status of Eutrophic, Potentially Eutrophic, Intermediate Status or Unpolluted. The data was then attributed onto marine waterbody geometry. |
