VTUAD: Vessel Type Underwater Acoustic Data

A curated dataset containing underwater acoustic signals categorized into five different classes based on the vessel type: Cargo, Tanker, Tug, Passengership, and Background. Different subsets of data were generated from the original data considering the distance from the vessel to the hydrophone picking up the vessel's sound. These subsets, or scenarios, were created considering inclusion and exclusion radii: the first scenario has an inclusion radius of 2km and an exclusion radius of 3km; the second is defined within the interval of 3km and 4km between inclusion and exclusion radius; the third scenario is defined within the interval between 4km and 6km. Also, environmental information, obtained from the CTD recorder, is available, containing five different signals: temperature, measured in Celsius; conductivity, measured in siemens per metre; pressure, in decibar; salinity, measured in psu; and sound speed, measured in meters per second. For every different instance, the average of the measures was considered.
