The borehole COSC-1 was drilled through the Lower Seve Nappe, as the first of two 2.5 km deep drill holes close to Åre, central Sweden.

As support for the COSC drilling project, an extensive seismic survey took place in 2014 in and around the newly drilled borehole COSC-1. The active seismic survey, among others, consisted of a high-resolution Zero-Offset Vertical Seismic Profiling (ZOVSP) experiment where seismic receivers were placed inside the borehole. For the seismic source signal a hydraulic hammer source (VIBSIST 3000) was used and activated over a period of 20 s as a sequence of impacts with increasing hit frequency. The wavefield was recorded in the borehole by 15 three-component receivers using a Sercel Slimwave geophone chain with an inter-tool spacing of 10 m. The ZOVSP was designed to result in a geophone spacing of 2 m over the whole borehole length. The source was about 30 meters away from the borehole. For component rotation, a check shot position was located about 1.9 km away from the borehole.

This data set contains two data sets: (1) the decoded, pre-processed three-component shot gather, and (2) the final-processed shot gather of only the vertical component.
