Grasmeijer 2010. Trends in SPM concentrations along the Dutch coast.

This report presents an analysis of trends in SPM concentrations based on predictions with a neural network, based on standardized data using MWTL data and based mixed-effect modelling using MWTL data. Main conclusion is that observed SPM concentrations in the North Sea show a small (but significant within the 95% confidence interval) decreasing trend since 1975. It is difficult to distinguish between the different effects on SPM concentrations in the North Sea.
