Isotopic ratios of Sr, Nd, and Pb were measured on MC-ICP-MS (Multi-collector-Inductively Coupled Plasma-Mass Spectrometry) with the newly-developed automated prepFAST sample purification method (Retzmann et al., 2017). The Sr, Nd and Pb isotope results reported here are the first such dataset obtained from the river Weser sediment. Combined with the statistical analysis, such as the principal component analysis, the dataset allows the evaluation of the contribution of various sources to the load of the river Weser, and enables the quantification of the flux of the river to the North Sea, and an estimate of the contribution of the river system to contaminants transported into the coastal zone. These estimates will also be of interest to stakeholders and governments for targeted management interventions of the socio-economically important Weser river system
