MARICAL Field Inter-Calibration Exercise

Report of the Field Inter-Calibration on Sampling and Analytical Procedures for Estonian, Finnish and Swedish Institutes Carrying Out HELCOM Monitoring

Estonian, Finnish and Swedish institutes carrying out national HELCOM Baltic Sea monitoring programmes participated in a field inter-calibration for parameters describing eutrophication. The main outcome was that this kind of comparisons are made all too seldom, and hence, it is suggested that the HELCOM parties could include this kind of field inter-calibrations, either between the neighbouring countries or as a basin-wide project, in their annual monitoring programmes
