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 Geophysical Instrument Pool Potsdam (GIPP) provides field instruments for (temporary) seismological studies (both controlled source and earthquake seismology) and for magnetotelluric (electromagnetic) experiments. The GIPP is operated by the GFZ German Research Centre for Geosciences. The instrument facility is open for academic use. Instrument applications are evaluated and ranked by an external steering board. See Haberland and Ritter (2016) and https://www.gfz.de/gipp for more information.
