The dataset contains SEG-Y data of a 2D shear wave survey carried out in the Mont Terri URL, Switzerland. The data were acquired using an ELVIS VII source in SH-mode and 1-C horizontal geophones mounted on a land-streamer. The data publication covers raw data, edited raw data (removal of corrupted records) and preprocessed data (correlation and vertical stacking) stored in SEG-Y format. The survey geometry (source point coordinates, receiver point coordinates, geometry pattern) is included.
This dataset contains passive seismic recordings taken in August/September 2026 at 10 locations forming a mini-array of ~1 km aperture in Saxon Lusatia (Germany) near the village of Oppitz. The measurements were part of the “Low Seismic Lab” project in collaboration with the DZA (German Centre for Astrophysics). The 10 three-component 4.5 Hz geophones remained in the field for ~17 days. The goal of this mini-array was to analyse the ambient seismic noise field, its characteristics, and directions. Raw data is provided in proprietary “Cube” format and standard miniSEED format. We also provide a stationXML file with station metadata.
The dataset contains the seismic weight drop data acquired in Private Reserve Santa Gracia, Chile. The data acquisition was conducted as a part of the EarthShape project in the subproject of Geophysical Imaging of the Deep EarthShape (GIDES). The seismic line was setup to cut across an existing borehole location with core and geophysical logging data available (Krone et al., 2021; Weckmann et al., 2020). The data was acquired to image the deep weathering zone identified by the borehole data across the seismic profile. Included in the datasets are the raw data of the CUBE data logger, SEG-Y data of the recorded shots, and the shot and receiver geometry data. A vital aspect of comprehending the interplay between geological and biological processes lies in the imaging of the critical zone, located deep beneath the surface, where the transition from unaltered bedrock to fragmented regolith occurs. It had been hypothesized that the depth of such weathering zone is dependent on the climate condition of the area. A more humid climate with higher precipitation will result in a deeper weathering front. As a part of the EarthShape project (SPP-1803 ‘EarthShape: Earth Surface Shaping by Biota’), specifically the Geophysical Imaging of the Deep EarthShape (GIDES - Grant No. KR 2073/5-1), we aim to image the weathering zone using the geophysical approach. Using the seismic method, we can differentiate different weathered layers based on the seismic velocity while also providing a 2D subsurface image of the critical zone. We conducted a seismic weight drop experiment in the Private Reserve Santa Gracia, Chile, to observe the depth of the weathering zone in a semi-arid climate and compare the resulting model with existing borehole data (Krone et al., 2021; Weckmann et al., 2020). The acquired data can then be used for multiple seismic imaging techniques, including body wave tomography and multichannel analysis of surface waves.
The occurrence of exposed high-metamorphic rocks (granulites) in combination with various gravity anomalies aligned along the direction of Variscan strike characterize a special terrain (Saxothuringikum) which has been sandwiched between two major tectonic units during the Variscan orogeny. Near surface geological studies show evidence that the Saxothuringian zone represents extended crust. Therefore the model of a "metamorphic core complex" is often used to explain the exhumation of the "Saxonian granulites". The thickness of the crust, the geometry of the Moho, and the composition of middle and lower crust that underlie such" metamorphic core complexes" have remained largely unconstrained. Because these physical parameters are critical for understanding the extensional processes acting at depth, we have carried out a seismic refraction experiment in order to resolve the deeper structure of an exposed "granulite-complex". From May 6th to May 13th 1995 a seismic refraction - wide angle reflection experiment was carried out as part of the DFG-priority program: "Orogenic processes – their quantification and simulation at the example of the Variscides". Two lines, A and B, were completed in two deployments (see map in GRANU95_report.pdf). In total 12 shots were fired and over 4500 seismograms were collected using 130 instruments. Only two different types of instruments (Reftek and PDAS) have been used for recording the explosions. All instruments were equipped with a 3-component 1Hz seismometer. The 90 km long NW-SE line (deployment A, 74 instruments) from Leipzig to the Erzgebirge through the Saxonian Granulites was carried out on the 8th and 9th May 1995. Additionally 56 stations were placed symmetrically to shotpoint D along line B (perpendicular to line A). Shots were fired on locations A1, A3, A4, A2 (see map in GRANU95_report.pdf). The station spacing for this deployment was around 1.3 km. The 260 km long SW-NE line (deployment B, 93 instruments) from Dresden to Bamberg, also crossing the Saxonian Granulites was completed from 11th to 13th May 1995. Every second instrument from deployment A was moved to complete line B. Shots were fired on locations B, C, D, E, F, G, H and I (see map in GRANU95_report.pdf) and recorded along line B and line A (perpendicular to line B) at a receiver spacing of about 2.6 km.
This data publication provides access to three-component (3C) passive seismic data collected in the National Park La Campana, Chile. The data acquisition was conducted as part of the EarthShape project, specifically the Geophysical Imaging of the Deep Earth (GIDES) initiative. The seismic array was strategically positioned to intersect an existing borehole location. This borehole boasts a wealth of data, including core samples and geophysical logging information. The passive seismic data plays a crucial role in imaging the structure of the deep weathering zone beneath the surface. The dataset includes the raw data captured by the CUBE data logger. This raw data can be converted into the widely used miniSEED format using the freely available GIPP (Geophysical Instruments Pool Potsdam) tools. This conversion facilitates seamless integration with other seismic analysis software, promoting broader utilization of the data by the scientific community.
In July and August 2017, off-shore seismic measurements have been carried out south of Sri Lanka as part of the INGON project. Main aim of this part of the project was to study the deep structure of the continent-ocean transition south of Sri Lanka and the early plate drift of India and Sri Lanka. The marine profile was extended by 15 seismic stations on-shore Sri Lanka, of which the data is contained in this data publication (land observations of airgun sources). This dataset consists of the raw (continuous) data of the land recorders (in proprietary cube and MSEED formats) and the shot records (airgun sources) in SEGY-format (standard exchange format).

In 2016, the Leibniz Institute for Applied Geophysics (Hannover, Germany) carried out two seismic surveys in the Lienz basin. The measurements are part of a DFG-funded project, which investigates the benefit of the application of modern multi-component reflection seismics preparatory to scientific drilling, in particular to the ICDP-project DOVE (Drilling Overdeepened Alpine Valleys). Four P-wave seismic profiles, perpendicular to the valley axes, were recorded using vibroseismic technique to gain structure and facies information. In addition, two SH-wave reflection seismics, one 6-component profile, two small 3-D layouts for P-wave and S-waves, as well as one P-wave and SH-wave refraction seismic profiles were measured for primarily methodological studies. Data show a good quality and, in a first quality control, the bedrock as well as internal structures of the basin are imaged.
The data set was acquired in the framework of the CRC 1211 “Earth – Evolution at the dry limit” which aims to study continuous longterm (Quaternary-Miocene) paleoclimatic/environmental records from the hyperarid core of the Atacama desert / N Chile covering the last up to 10 Ma. As part of this project, three clay pans were investigated in the Coastal Cordillera (Huara 20° 4'32.75"S; 69°55'1.46"W; PAG: 21°32'27.39"S; 69°54'47.21"W; Paranal 24°29'20.53"S; 70° 8'54.63"W). The clay pans are located along a latitudinal transect across the hyperarid core of the Atacama from 20° S to 24.5° S. The seismic survey comprised a couple of crossing 2D high-resolution seismic lines per each of the clay pans, acquired with vertical component geophones, Geode recorders and a PEG-40 accelerated weight drop as source.
Within the Inter-Wind project we study wind turbine (WT) emissions with ground motion and acoustic measurements which are accompanied by the acquisition of meteorological parameters as well as psychological surveys of residents living in the vicinity of the wind farms. Measurements are conducted on the Swabian Alb in Southern Germany at wind farms Tegelberg and Lauterstein in multiple interdisciplinary campaigns. Here we focus on measurements with line and ring layouts which are directed at improving the prediction of ground-motion emissions of WTs. This dataset contains recorder log files. Seismic data is stored at GEOFON, network 4C (2020 - 2024, Ritter and Gaßner 2022).
