The UKGEOS site in Glasgow has repurposed an abandoned coal mine to investigate its potential as a heat source and heat sink, and its borehole infrastructure includes pre-installed fibre-optic cables. DAS is a novel seismic monitoring technique that utilizes fibre-optic cables to measure small acoustic and seismic vibrations. Comparable to a very densely spaced hydrophone or geophone array, DAS provides unparalleled data resolution and insights into the subsurface. This dataset provides both active source and passive measurements of DAS at the UKGEOS Site 2 prior to the heat pump installation, providing geophysical baseline measurements of the mine. Alongside the acquired DAS data, data from a hydrophone array co-located to the fibre-optic cable was collected during the active source survey to provide a means of comparison to the DAS.

GGA05 was used as the receiver borehole, hosting the fibre-optic cable and the DHA-7 24-channel hydrophones. The DAS was recorded using a Silixa DAS interrogator (iDAS). GGA04 acted as the source borehole, into which a SGS42 Sparker Probe was lowered and connected to an Impulse Generator (IPG) 5000 Downhole Sparker to generate P-waves. During the active survey, the P-wave sparker was set off in 4-meter intervals between 6- and 46-meters depth, and set off 6-7 times at each shot depth. For the passive survey, the iDAS was acquiring during the night (23:00 to 07:45) between February 1st to 2nd. There was ongoing construction at the site during all three days of surveying.
