Underwater noise signatures of ships in Australian waters
Recordings of ship noise were analysed to build a catalogue of ship noise signatures in Australian waters, including source spectra and source levels. The data described by this record is derived from an initial set of five deployments by the Integrated Marine Observing System (IMOS) acoustic observatories.

- Statement
- Estimates of the noise source spectra of ships were obtained using geo-referenced AIS data and acoustic data from the Integrated Marine Observing System (IMOS). The results of applying the software to recordings from an initial set of five IMOS deployments from two locations (Perth Canyon W.A. and Portland S.A.) and spanning a total of 1463 days. This ship source level data is essential in the cumulative noise modelling process given it provides the source levels of the different types/class sizes of ships being modelled. This data contributes to the start of an Australian database of ship noise data, although it had a limited range of vessel types (mainly all cargo vessels and some tankers) and future acoustic logger deployments will need to strategically identify areas that maximises this, if this is an aim.
