Full description

Distributed Acoustic Sensing (DAS) transforms fibre optic cable as one continuous sensing element with thousands of sensors at meter-spacing along the cable, measuring at a broad range of frequency (0.001 – 1000 Hz). A DAS interrogator sends laser signal pulses along the cable and continuously monitors the phase and amplitude of the backscattered light. As seismic wave propagates across the cable, the cable is slightly stretched or compressed, and the dynamic strain can be measured by the change in the optical phase of the backscattering. DAS arrays are robust and can be deployed in many environments including boreholes, urban telecommunication networks, subsea cables, and direct active surveys. DAS provides new opportunities to revolutionize geophysical studies in high resolution subsurface imaging and seismic source detection. This data collection contains the time series, metadata, and derivative products of DAS array deployments collected using AuScope-funded interrogators.
