A Database of Underwater Radiated Noise from Small Vessels in the Coastal Area

As such, not a lot of data is available for the URN of unidentified vessels of opportunity (VOO), especially for small vessels that do not carry an automatic identification systems (AIS). To this end, we assembled a database of 1148 VOO’s URN from acoustic and visual recordings of ferries, fishing boats, yachts, and small speed boats made within Šibenik canal, Croatia.

The database comprises source pressure levels at the closest point of approach, picture and video of the vessel, and the vessel’s speed, size, and type. A shared webpage allows filtering and comparing vessel types and characteristics. To the best of our knowledge, this is one of the largest databases of vessel URN in general and the most extensive database for small coastal vessels.
