Confidence rating of marine eutrophication assessments

This report presents the development of a methodology for assessing confidence in eutrophication status classifications. The method can be considered as a secondary assessment, supporting the primary assessment of eutrophication status. The confidence assessment is based on a transparent scoring of the 'value' of the indicators on which the primary assessment is made. Such secondary assessment of confidence represents a first step towards linking status classification with information regarding their accuracy and precision and ultimately a tool for improving or targeting actions to improve the health of the marine environment.



Norwegian case study

The objectives of CONFIRM are to develop a methodology for confidence rating of marine eutrophication assessments, including guidance and an assessment tool in the form of a downloadable open-source program. In addition to the methodology and programs for confidence rating, the tools include possibilities of weighting between indicators (per category/quality element) and between categories and quality elements.
