Abstract
The Arctic soundscape is naturally quite complex, but many parts of the Arctic have also historically had very low levels of ship noise. However, ship traffic is increasing throughout the Arctic, which is likely leading to increased levels of underwater noise, causing changes in this soundscape. In this study, we thoroughly quantified ship noise in passive acoustic data collected at 10 sites in the western Canadian Arctic between 2014 and 2020, with data collected from between one and three years at each site. We paired the acoustic data with automatic identification system ship data to collect information on the individual ships creating noise. We quantified the presence of ship noise within all of the acoustic data, statistically examined the influence of different static and dynamic ship variables on sound levels, and estimated source levels of ships that traveled close to the acoustic recorder. These analyses represent the first detailed examination of ship noise in this region of the Arctic, and the results provide valuable information for future soundscape studies, as well as relevant information for the management of ship noise in the Arctic.
