• We summarize the results of more than 3 years of operation of a permanent Ocean Bottom Seismometer (OBS) deployed 40 km offshore Catalonia (northeastern Spain) in terms of the site ambient noise conditions and quality of the data acquired. As observed on most of the ocean-floor observatories, the noise level at the OBS site is quite large on all components. However, the integration of the OBS station into the Catalan seismic network has allowed to improve hypocenter locations.
