This seismic crosshole dataset was acquired in the context of the DOVE project (Drilling Overdeep-ened Alpine Valleys) at ICDP site 5068_1 (Tannwald Basin) to image the glacial sediments at sub-meter scale. It consists of the field data with geographical coordinates.
The project aims to investigate the landscape evolution in the Alpine region by drilling overdeep-ened valleys and analyzing the cores (DOVE-Phase 1 Scientific Team, Schaller et al., 2023, Schuster et al., 2024). At site 5068_1 (Tannwald Basin), three boreholes were drilled to a depth of about 160 m depth, reaching the bedrock. Boreholes 5068_1_A and 5068_1_B were flush drilling and bore-hole 5068_1_C was cored. In 2022, the boreholes were used to perform high-resolution crosshole seismic measurements in order to image the glacial sediments at sub-meter scale. This dataset con-sists of the seismic field data with geographical coordinates and is subdivided by
(1) the used source and receiver borehole equipment (P: sparker and 24-station hydrophone string, SV: vertically polarizing shear wave source and three-component geophone string with eight geophones, SH: horizontally polarizing shear wave source and three-component geophone string with eight geophones),
(2) the respective borehole plane (BA, BC, and AC), and
(3) the acquisition geometry (STRING, CIRCLE, LINE_BA, LINE_BC, LINE_AC).
The surface seismic data (CIRCLE, LINE_BA, LINE_BC, LINE_AC) was recorded by three-component geophones. The seismic data is provided in SEGY Rev. 1.0 format together with geometry files in csv-format.
The dataset contains waveform data of shallow seismic profiles at two locations in the western part of the Alai valley, Kyrgyzstan. At each location a “long” profile (~5 km and ~2.5 km length, respectively) and one or two short profiles (~120 m and ~250 m) were acquired, centered on known or presumed tectonic faults. As sources, a trailer-mounted weight drop and a hammer were used. The measurements were part of the CaTeNA project.
Within the sub-project "The recent deformation in the Pamir based on seismic and geodetic data, dynamic landslide-susceptibility and risk analysis, and seismic imaging of the North Pamir Thrust", which forms part of the international and interdisciplinary CaTeNA project (Climatic and Tectonic Natural Hazards in Central Asia), shallow seismic profiling at two locations has been carried out in the Alai Valley, southern Kyrgyzstan, to investigate the spatio-temporal evolution of the Pamir Frontal Thrust (PFT). Eight seismic profiles were acquired in September 2019 at two locations in the western part of the Alai valley, (1) in the village of Achyk Suu and b) at the Koman fault (SSW of the village of Kashka Suu). At each location a long profile (5 and 2.5km, respectively) and one or two short profiles (~250m) across interesting (presumed) fault structures were acquired.
