Geochemical Atlas of the Federal Republic of Germany (1985), Element concentrations in stream waters and stream sediments, Data

Between 1977 and 1983, the Federal Institute for Geosciences and Natural Resources (BGR) took approx. 80,000 water samples and 70,000 sediment samples from streams and rivers in several sampling campaigns on the territory of the Federal Republic of Germany at that time and examined them geochemically. In addition to the geochemical prospection of areas with potentially deposits, the aim of the investigations was also to record indications of anthropogenic environmental pollution. The results of these investigations were published in the Geochemical Atlas of the Federal Republic of Germany (Fauth et al., 1985). The data collected within the framework of the Geochemical Atlas of the Federal Republic of Germany in 1985 is a geochemical survey of the former territory of the Federal Republic of Germany which is unique in its high sampling density. All later geochemical investigations were carried out with a much lower sampling density. This valuable and irretrievable data is now being made generally available via the BGR geoportals. In addition to the digital provision of the original data material, the texts from Fauth et al. (1985) and distribution maps produced according to the method used in 1985, the data were reprocessed using modern methods. This download contains the original data material created in 1985. The original dataset is stored in a relational Microsoft Access database, but the associated retrieval program is no longer executable under the current operating systems. Moreover, Microsoft ACCESS is only available under Microsoft Windows. Therefore, the data were converted into a tabular structure and into actual data formats (*.xlsx, *.csv). In addition, the information on sampling and the analytical methods used contained in Fauth et al. (1985) is attached to the downloads.
