Apparently, underwater acoustics can answer this question. Using detection and classification techniques, a vessel can be identified by its underwater radiated noise (URN). The result can be used as a remote sensing enabling technique for monitoring URN level for noise pollution monitoring; for identifying malfunctions in a vessel for predictive maintenance; or for vessel tracking. But the first step is to collect a large enough dataset that will allow performance evaluation for any detection and classification algorithm.<\/p><p>In this project, we have collected a dataset of acoustic data containing shipping URN and have linked it to our own dataset of AIS. The latter is a device, mandatory for vessels over 12 feet, that continuously reports the ID, speed, and location of the vessel. By connecting acoustic and AIS information, we are able to match between a passing vessel and its URN, thereby providing ground truth for the recorded vessel.\u00a0<\/p><p>To obtain the data, we have built a self-made underwater acoustic passive receiver that can record continuously raw acoustic data from several hydrophones (receiving elements) for a few months. The recorder was deployed by our team of scuba divers in the Rosh Carmel area across from Haifa, Israel, at a depth of 30m some 700m from the shipping line exiting the Haifa port.\u00a0<\/p><p>The collected dataset contains 5 months of raw acoustic data (flac files of 5min, between 3-5\/2022 and 10\/2022-1\/2023). Analyzing this dataset and linking it to AIS, we have identified the URN of 323 different\u00a0ships which passed in the range of 200 to 9000 meters from our recorder.<\/p><p><img decoding=\"async\" class=\"size-medium wp-image-12058 alignleft\" src=\"https:\/\/dsrc.haifa.ac.il\/wp-content\/uploads\/2023\/11\/Picture1-300x140.jpg\" alt=\"\" width=\"300\" height=\"140\" srcset=\"https:\/\/dsrc.haifa.ac.il\/wp-content\/uploads\/2023\/11\/Picture1-300x140.jpg 300w, https:\/\/dsrc.haifa.ac.il\/wp-content\/uploads\/2023\/11\/Picture1.jpg 390w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><img decoding=\"async\" class=\"size-full wp-image-12059 alignnone\" src=\"https:\/\/dsrc.haifa.ac.il\/wp-content\/uploads\/2023\/11\/Picture2.png\" alt=\"\" width=\"264\" height=\"173\" \/><\/p><p><em>Left panel: AIS dataset collected in the Haifa bay, Upper middle panel: acoustic signature of a merchant vessel collected in the bay, Lower middle panel: picture from the deployment site, right panel: cavitation noise from the thruster of a vessel.<\/em><\/p><p>This research is supported by a dataset collection grant from the\u00a0<span style=\"text-decoration: underline;\"><strong><a href=\"https:\/\/dsrc.haifa.ac.il\/\">Data Science Research Center<\/a>\u00a0<\/strong><\/span>(DSRC), University of Haifa, Israel.
