  • The national drill core repository of the BGR in Berlin-Spandau includes drilled rocks from various research programs such as BGR, BMBF, GESEP and ICDP. Core material from petroleum industry is also represented. The locations of the wells are given worldwide and visualized on a map. Detailed information is linked to other BGR online services.

  • Compilation of the European Quaternary marine geology (section of Germany). The original map consists of data at highest available spatial resolution, map scale („multi-resolution“-concept) and data completeness vary depending on the project partner (as of 2019 April). Project partners are the national geological services of the participating countries. According to the Data Specification on Geology (D2.8.II.4_v3.0) the geological map (section of Germany) provides INSPIRE-compliant data. The WMS EMODnet-DE Quaternary (INSPIRE) contains layers of the geologic units (GE.GeologicUnit) displayed correspondingly to the INSPIRE portrayal rules. The geologic units are represented graphically by stratigraphy (GE.GeologicUnit.AgeOfRocks) and lithology (GE.GeologicUnit.Lithology). The portrayal of the lithology is defined by the first named rock. Via the getFeatureInfo request the user obtains detailed information on the lithology, stratigraphy (age) and genesis (event environment and event process).

  • The map of gravel deposits on a scale of 1 : 250,000 shows the distribution of sediments that contain gravel. The gravel fractions in the upper 0.2 m below the seabed surface are shown over the entire area. In the depth intervals 0-1 m, 1-2 m and 2-3 m, the gravel occurrences are additionally mapped selectively, depending on the drilling data. The proportion of gravel in the sediment is subdivided into five classes, each in gradations of 20 wt.% gravel. The maps are based on sediment samples taken from the seabed surface down to a depth of 0.2 m and on layer descriptions from boreholes.

  • The maps show a total of 14 newly interpreted base horizons (Middle Miocene unconformity to the base of the Zechstein) of depth maps and a total of 13 layer thickness maps from the Lower Miocene to the Zechstein.

  • The map shows the distribution of potential sluiced sand north of the East Frisian Islands. There, primarily sands of medium grain size are needed for the protection of island coasts in order to compensate for the constant coastal erosion caused by rising sea levels, storm surge events and current-induced material removal and transport. The study area is limited to an area bounded on land by the -8 m NN isobath and on sea by the southern traffic separation area ("Terschelling - German Bight"). Large-scale extraction of sluiced sand is only possible down to a depth of 3 m. For future needs, local depth extractions down to a depth of 20 m below the seabed surface may have to be included in the considerations. For the evaluation of the grain size spectrum searched for, 2 maps were prepared. The observation depth differs with regard to the evaluation for a surface sampling to a depth of 3 m and a second one for depth sampling to a depth of 20 m below the seabed. Two classes were kept, showing potential occurrences of sand in the depth ranges mentioned. If the data basis is available in high quality, the general class "sand" was specified and subdivided into "fine to medium sand".

  • The map of gravel deposits on a scale of 1 : 250,000 shows the distribution of sediments that contain gravel. The gravel fractions in the upper 0.2 m below the seabed surface are shown over the entire area. In the depth intervals 0-1 m, 1-2 m and 2-3 m, the gravel occurrences are additionally mapped selectively, depending on the drilling data. The proportion of gravel in the sediment is subdivided into five classes, each in gradations of 20 wt.% gravel. The maps are based on sediment samples taken from the seabed surface down to a depth of 0.2 m and on layer descriptions from boreholes.

  • This WMS presents the following data: "Sediment distribution German North Sea - classification according to FIGGE (1981)"; "Sediment distribution German North Sea - classification according to FOLK (1954, 1974)" - Description of the data see there.

  • A bathymetric map shows the topography of the seabed using depth contours. For the GPDN project area, it was necessary to create a specially adapted bathymetric map in order to achieve a uniform reference level for the creation of various 3D models, among other things.

  • The protective potential of the groundwater cover layers assesses the protective effect of the unsaturated zone, including the soil overlying the upper aquifer with potential groundwater supply, against the vertical intrusion of contaminants. The development of nationwide information on the protective potential of the groundwater cover between 2002 and 2005 was a contribution by the State Geological Surveys of Germany (SGD) to the initial description of groundwater bodies as part of the reporting obligations for the implementation of the European Water Framework Directive. The determination of the protection potential basically follows the guidelines of the LAWA working aid (as of 2003) and provides for a classification into the categories “favourable”, “medium” and “unfavourable” in the map representation. Depending on the digital availability of the required information bases, the Geological Surveys of the individual federal states have essentially developed two solutions: 1). In the federal states of Berlin, Brandenburg, Bremen, Hamburg, Hesse, Lower Saxony, North Rhine-Westphalia, Rhineland-Palatinate, Schleswig-Holstein, Saarland and Saxony, available area information (hydrogeological overview map HÜK250 or other state-specific bases) was compiled using conventional empirical methods and/or point information (layer lists from boreholes) with hydrogeological information content was classified with regard to a potential protective effect against the intrusion of contaminants and interpreted according to the specifications of LAWA. 2). In Baden-Württemberg, Bavaria, Saxony-Anhalt and Thuringia, the method developed by the SGD for determining the protective function of the groundwater cover (HÖLTING et al. 1995) was applied. This method provides more differentiated information, but requires comprehensive information on seepage rate/groundwater recharge, usable field capacity of the soil, rock type and thickness of the groundwater cover below the soil, structural properties of the bedrock and artesian pressure conditions. The classification, based on a scoring system, was translated into the categories specified in the LAWA working aid. Areas with stagnant surface water and insufficient information density were not assessed.

  • Web Map Service (WMS) of the map Groups of soil parent material in Germany 1:5,000,000. The presented map at scale 1:5,000,000 shows the distribution of 15 soil parent material groups in Germany with polygons of at least 64 square kilometers. Parent material is the rock, from which soil is formed. It was derived from the landuse use stratified soil map of Germany at scale 1:1,000,000. The version 3.0 of the map is based on the Digital Landscape Model 1:1,000,000 (DLM1000) of the Federal Agency for Cartography and Geodesy.
