The ocean-bottom seismometers (OBS) underwent submersible testing at the EMEPC facilities.

The OBS is a seismometer that is designed to record acoustic and seismic events at the sea floor. These seismic and acoustic signals may be caused by different sources, such as earthquakes and tremors as well as by artificial sources. The deployment of three OBS’s in a triangular formation around the Cadiz Observatory, will give information about the deep structure of the Earth’s crust and upper mantle, and will complement data generated by the EGIM.

The OBS were designed and built by the IDL group at FCUL led by Luis Matias and Carlos Corela. Sea trials are scheduled for mid-April 2021.
