GEMAS (Geochemical Mapping of Agricultural and Grazing Land Soil in Europe) is a cooperative project between the Geochemistry Expert Group of EuroGeoSurveys and Eurometeaux. In total, more than 60 international organisations and institutions worldwide were involved in the implementation of the project. During 2008 and 2009, a total of 2219 samples of agricultural (arable land soils, 0 – 20 cm, Ap samples) and 2127 samples of grazing land (pasture land soils, 0 – 10 cm, Gr samples) soil were collected at a density of 1 site/2 500 km² each from 33 European countries, covering an area of 5,600,000 km². All samples were analysed for 52 chemical elements after an aqua regia extraction, 41 by XRF (total), TC and TOC. In addition, the agricultural soil samples were analysed for 57 elements in a mobile metal ion (MMI®) extraction and Pb isotopes. All analytical results were subject to tight external quality control procedures. The GEMAS project thus provides for the first time fully harmonised data for element concentrations and bioavailability of the elements at the continental (European) scale. The downloadable files present the areal distribution of the element contents determined by different analytical methods in the shape of colour shaded contour maps with a classification in 7 and 72 levels each.

The project Geo3D-Oder aims at establishing geological 3D models of three sub-catchment areas along the Oder river in the federal state of Brandenburg in the north of the confluence of the Neisse river. The combined model of the sub-catchments shall serve as a basis for a quantitative groundwater model. In this context the model shows the aquitardes formed by the cohesive sediments of ground moraines, glaciolacustrine deposits and sediments of the Holstein interglacial period up to the till of the younger Elsterian ice age as the lowest horizon. For the time being any other space is interpreted undifferentiated as an aquifer. The respective data basis comes from the “Lithofazieskarte Quartär (LKQ 50)” of the former GDR at a scale of 1 : 50,000. The structural model of the sub-catchment area „Mittlere Oder“ constitutes the first model section. It consists of the ground surface derived from the Digital Terrain Model DGM 50 and ten horizons confined by top and base layers. As a simplification, the model assumes a concordant sequence of horizons without any faults. Due to data gaps for several horizons just a hypothetical modelling is feasible in relevant parts applying a specifically developed methodology. For this purpose, auxiliary horizons (“virtual horizons”) are built based on the elevation of other horizons in order to serve as modeling constraints. The resulting horizons were finished using several tools provided by the modeling software SKUA-GOCAD.

The data set includes the navigation data of those 2D-seismic surveys, which fall in the scope of application of the German Geological Data Act and from which at least one profile line lies within the German exclusive economic zone or crosses is boundary.

The International Geological Map of Europe and the Mediteranean Regions 1 : 1 500 000 ("Carte Géologique Internationale de l'Europe et des Régions Méditerranéennes 1 : 1 500 000") shows the geology of the European continent from the Ural mountains in the east up to Island in the west and the whole mediteranean region in the south. The geology is differenciated in stratigraphy, igneous and metamorphic rocks. In addition there are two legend sheets and a title sheet. The language of the series is French.

The data set includes the polygons that surround the areas covered by those 3D-seismic surveys, which fall in the scope of application of the German Geological Data Act and which at least partially lie within the German exclusive economic zone.

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. The downloads show the distribution of the sample points and the sampled area in the form of a (smoothed) 2 km buffer around the sample points.
