INSPIRE: Airborne geophysical surveys for mapping the shallow subsurface in Germany (D-AERO)

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. The 13 GML files for each airborne geophysical survey area together with a Readme.txt file are provided in ZIP format (D-AERO-INSPIRE.zip). The Readme.text file (German/English) contains detailed information on the GML files content. Data transformation was proceeded by using the INSPIRE Solution Pack for FME according to the INSPIRE requirements of data specification Geology (D2.8.II.4_v3.0), Sub-theme Geophysics.

World Stress Map 2025

The World Stress Map (WSM) is a global compilation of information on the crustal present-day stress field. It is a collaborative project between academia and industry that aims to characterize the stress pattern and to understand the stress sources. It commenced in 1986 as a project of the International Lithosphere Program under the leadership of Mary-Lou Zoback. From 1995-2008 it was a project of the Heidelberg Academy of Sciences and Humanities headed first by Karl Fuchs and then by Friedemann Wenzel. Since 2009 the WSM is maintained at the GFZ Helmholtz Centre for Geosciences. All stress information is analysed and compiled in a standardized format and quality-ranked for reliability and comparability on a global scale. The stress map displays A-C quality stress data records of the Earth’s crust from the WSM database release 2025 (doi:10.5880/WSM.2025.001). Further detailed information on the WSM quality ranking scheme 2025, guidelines for the borehole logging data, and software for stress map generation and the stress pattern analysis is available at www.world-stress-map.org.

Infrasound array signal processing results of far-field stations for the Falcon 9 rocket stage re-entry over central Europe on 19 February 2025

Supplementary information to the manuscript “Seismoacoustic analysis of a Falcon 9 rocket stage re-entry over central Europe on 19 February 2025” by Hupe et al. (2026). Results of the Progressive Multi-Channel Correlation (PMCC) processing for far-field infrasound stations, displayed in Figure 7 of the manuscript (IS26 in Germany, NRSI in Norway, HFSI in Sweden). The netcdf files contain the following detection parameters of single arrivals: Time, duration, back-azimuth, apparent velocity, frequency, family identifier. Data format: One .nc file for each station.

Geophysikalische Untersuchungen

Die Datenebene enthält Informationen zu Messgebieten, Profillinien und Messkampagnen geophysikalischer Untersuchungen entsprechend der Fachbereiche getrennt für Geoelektrik, Gravimetrie, Geomagnetik und Seismik. Geoelektrik: Übersicht über lokale Messgebiete, die von verschiedenen Firmen bearbeitet, sowie Untersuchungen, die vom LAGB beauftragt oder selbst durchgeführt wurden. Vor 1990 betreffen die von Firmen durchgeführten Untersuchungen zumeist Messungen des VEB Geophysik Leipzig, nach 1990 Messungen verschiedener Ingenieurbüros, die nach Lagerstättengesetz/Geologiedatengesetz an das LAGB gemeldet wurden. Seismik: Die Profilanlage seismischer Messungen ist unterteilt in 2D-reflexionsseismische Messungen zur Erkundung geologischer Strukturen und der Rohstoffexploration in bis ca. 5 km Tiefe sowie die Messungen der Refraktionsseismik und Weitwinkelreflexionsseismik, welche den Aufbau der Erdkruste in bis zu 40 km Tiefe untersuchen. Die tiefenseismischen Profile werden weiterhin durch die eingesetzten Messmethoden unterschieden. Untersuchungsgebiete reflexionsseismischer 3D-Messungen markieren Gebiete der detaillierten Exploration von mit Hilfe mehrerer Quellen gleichzeitig angeregter seismischer Signale, welche an flächenhaft ausgebrachten Geophonen registriert werden. Gravimetrie und Geomagnetik: Aufgeführt sind die Messgebietsumrisse und Informationen der Regionalmessungen in Sachsen-Anhalt.

OBS stations of the GEOSTOR project in the German Bight and in the German Baltic Sea (WMS)

The dataset includes the locations of OBS stations (Ocean Bottom Seismometers) operated in the German Bight during cruise MSM100 with R.V. Maria S. Merian. The time interval from 13.05.2021 to 15.05.2021 has been analysed in a phase without airgun operation for passive recording with 4.5 Hz geophones. Furthermore, the dataset contains locations of 3 broadband OBS systems which were operated during an experiment at the Darss ramp in the German Baltic Sea. The records were analysed in the time interval 23.01.2018 to 01.04.2018.

Higher frequency data products of the International Monitoring System’s infrasound stations

This dataset consists of data products derived from broadband signal detection lists that have been processed for the certified infrasound stations of the International Monitoring System. More specifically, within the CTBT-relevant infrasound range (around 0.01-4 Hz), this dataset covers higher frequencies (1-3 Hz) and is therefore called the ‘hf’ product. The temporal resolution (time step and window length) is 5 min. For processing the infrasound data, the Progressive Multi-Channel Correlation (PMCC) array processing algorithm with a one-third octave frequency band configuration between 0.01 and 4 Hz has been used. The detected signals from the most dominant directions in terms of number of arrivals within a time window and the product-specific frequency range are summarized at predefined time steps. Along with several detection parameters such as the back azimuth, apparent velocity, or mean frequency, additional quantities for assessing the relative quality of the detection parameters are provided. The dataset is available as a compressed .zip file containing the yearly data products (.nc files, NetCDF format) of all certified stations (since 2003). Further information on the processing and details about the open-access data products can be found in: Hupe et al. (2022), IMS infrasound data products for atmospheric studies and civilian applications, Earth System Science Data, doi:10.5194/essd-14-4201-2022

Very low frequency data products of the International Monitoring System’s infrasound stations

This dataset consists of data products derived from broadband signal detection lists that have been processed for the certified infrasound stations of the International Monitoring System. More specifically, this dataset, called the ‘maw’ product, covers a very low frequency range of infrasound (0.02-0.07 Hz). The temporal resolution (time step and window length) is 30 min. For processing the infrasound data, the Progressive Multi-Channel Correlation (PMCC) array processing algorithm with a one-third octave frequency band configuration between 0.01 and 4 Hz has been used. The detected signals from the most dominant directions in terms of number of arrivals within a time window and the product-specific frequency range are summarized at predefined time steps.
