  • The study of the geodynamic evolution of the Arctic continental margin and opening of the Arctic Ocean represents a primary target of BGR research and is studied within the frame of the CASE programme. In addition to onshore geological investigations, BGR conducts airborne aeromagnetic surveys. The available series contains the results of aeromagnetic surveys from the CASE program as well as cooperation projects (PMAP, NARES & NOGRAM), which were obtained with helicopters or fixed-wing aircraft in the Arctic.

  • As part of the PMAP-CASE (Polar Margin Aeromagnetic Program - Circum-Arctic Structural Events) expeditions, two surveys were conducted in consecutive seasons in 1997 and 1998. Cooperating partners were the Department of National Defence (DND), GSC Ottawa and the Institute for Aerospace Research Ottawa (IAR-NRC). The surveys covered the areas of the northern continental margin of Greenland including the northern Nansen Land and western Johannes V. Jensen Land, as well as parts of the Lincoln Sea. The objective of the campaigns was to investigate the structures of the upper crust of the Morris Jesup Plateau and the correlation of magnetic anomalies with known structures and geologic units on land (Franklinian Basin, Kap Washington volcanics, and volcanic dyke swarms). Airborne magnetic surveys (Convair 580) were conducted with a 3 km flight line spacing, and control lines were flown every 30 km. Data were recorded at a constant flight altitude of 300 m above ground. Approximately 30000 km of line data were collected during the two expeditions, covering an area of 73000 km².

  • The WMS D-AERO (INSPIRE) comprises airborne geophysical surveys for mapping the shallow subsurface in Germany. Since the eighties BGR carries out helicopter borne measurements in Germany as well as in neighbouring and distant countries. In particular a series of continuous areas on the German North Sea coast are flown during the last years within the context of the D-AERO project. The helicopter of type Sikorsky S-76B is operated for the airborne geophysical survey of the earth's subsurface. Usually airborne electromagnetic, magnetic and radiometric measurements are carried out. According to the Data Specification on Geology (D2.8.II.4_v3.0, sub-theme Geophysics) the information with respect to the airborne geophysical surveys is INSPIRE-compliant. The WMS D-AERO (INSPIRE) contains for each airborne geophysical survey one layer, e.g. GE.flightLine.G081Cuxhaven. The flightlines are displayed correspondingly to the INSPIRE portrayal rules. Via the getFeatureInfo request, the user obtains the content of the INSPIRE attributes platformType und profileType. Additionally, the WMS contains a campaign layer (GE.airborneGeophysicalSurvey) with the INSPIRE attributes campaignType and surveyType.

  • Two strong eruptions of Stromboli Volcano (38.789°N 15.213°E, 920 m) occurred on July 3rd and August 28th 2019. This data set provides the infrasound records in terms of raw pressure data in Pascal of both eruptions available at BGR’s infrasound array I26DE in Germany as well as infrasound arrays OHP and CEA in France. The publication “Using dense seismo-acoustic network to provide timely warning of the 2019 paroxysmal Stromboli eruptions” (Le Pichon et al., 2021, Scientific Reports) provides further details on this data set and its scientific application. Data format: The data are provided as ASCII files (separate file for each infrasound sensor and hour of measurement, plus a README file).

  • The WMS SuK-Nord (INSPIRE) shows the geological distribution of aggregates (sand and gravel) in Northern Germany, especially north of the southernmost maximum of the Scandinavian inland ice sheet (Saalian and Elsterian glaciation). According to the Data Specification on Mineral Resources (D2.8.III.21) and Geology (D2.8.II.4_v3.0) the map provides INSPIRE-compliant data. The WMS GK2000 Lagerstätten (INSPIRE) contains the following layers: MR.MineralOccurence.Commodity represents the distribution of sand and gravel. GE.GeomorphologicFeature shows the southernmost maximum of the Scandinavian inland ice sheet (Saalian and Elsterian glaciation).

  • Within the framework of DOVE, the project Chatseis combines two seismic methods to increase resolution and reliability of the seismic data; i.e. reflection imaging and full-waveform inversion. To acquire the optimal data for the tasks in the project Chatseis, the German Federal Institute for Geosciences and Resources conducted two seismic surveys together with the Leibniz Institute for Applied Geophysics and the Bayerisches Landesamt für Umwelt. At the DOVE-site 5068_3 (Schäftlarn), the project team registered seismic P-wave data with explosive and vibration sources and different geophones as well as S-wave data with a small-scale vibratory source and a landstreamer system on three profiles (in total ca 3.8 km, 100 GB for P-wave and ca 2.6 km, 16 GB for S-wave).

  • The CO2 storage potential of the Middle Buntsandstein Subgroup within the Exclusive Economic Zone (EEZ) of the German North Sea was analysed within the framework of the GEOSTOR-Project. A total of 71 potential storage sites were mapped based on existing 3D models, seismic and well data. Static CO2 capacities were calculated for each structure using Monte Carlo simulations with 10,000 iterations to account for uncertainties. All potential reservoirs were evaluated based on their static capacity, burial depth, top seal integrity and trap type. Analysis identified 38 potential storage sites with burial depths between 800 m and 4500 m, reservoir capacities (P50) above 5 Mt CO2 and suitable sealing units. The best storage conditions are expected on the West Schleswig Block where salt-controlled anticlines with moderate burial depths, large reservoir capacities and limited lateral flow barriers are the dominant trap types. Relatively poor storage conditions can be anticipated for small (P50 <5 Mt CO2), deeply buried (> 4500 m) and structurally complex potential storage sites in the Horn and Central Graben.

  • Within the framework of the GEOSTOR Project, the CO2 storage potential of the Jurassic succession in the German Central Graben was analysed. Twelve potential trap structures were initially mapped along the base of the Kimmeridge Clay Formation, which serves as the primary seal for potential reservoir sandstones within the Central Graben Subgroup. The Kimmeridge Clay Formation is generally continuously distributed across the German Central Graben, with only localized penetrations by rising salt diapirs. In contrast, the Central Graben Subgroup, serving as a potential reservoir unit, exhibits an uneven distribution across the area, limiting the presence and continuity of reservoir rocks within each trap structure. To further delineate the spatial extent of the mapped reservoir structures, the base of the Central Graben Subgroup was used as an additional reference layer. Due to the intermittent nature of Jurassic sandstones within the Central Graben Subgroup, a subsequent analysis classified each structure based on borehole data to confirm the presence of reservoir sands. Structures were categorized as ‘proven,’ ‘not present,’ or ‘uncertain’ depending on sandstone availability and continuity within the trap. All mapped reservoir structures are buried at depths ranging from 2225 to 3043 meters (apex depth) and are considered closed systems, situated within a complex structural network of salt diapirs, faults, and pinch-outs. Capacity calculations were conducted following the method outlined by Fuhrmann et al. (2024), and the horizons used for mapping are based on the work of Müller et al. (2023) and Thöle et al. (2021).

  • The IGME5000-DE (INSPIRE) represents the pre-quaternary bedrock geology (section of Germany) of the European map on a scale of 1:5,000,000. According to the Data Specification on Geology (D2.8.II.4_v3.0) the geological map provides INSPIRE-compliant data. The WMS IGME5000-DE contains layers of the geologic units (GE.GeologicUnit) and faults (GE.GeologicFault) mostly displayed according to the INSPIRE portrayal rules. The geologic units are represented graphically by stratigraphy (GE.GeologicUnit.AgeOfRocks) and lithology (GE.GeologicUnit.Lithology). For different geochronologic minimum and maximum ages, e.g. Ordovician - Silurian, the portrayal is defined by the color of the geochronologic minimum age (olderNamedAge). The portrayal of the lithology is defined by the first named rock or rock group. In case of the geologic units the user obtains detailed information via the getFeatureInfo request on the lithology and stratigraphy (age).
