Impact of ship noise on the underwater soundscape of Eclipse Sound in the northeastern Canadian Arctic
Eclipse Sound, in the northeastern Canadian Arctic, has experienced a substantial increase in ship traffic due to growing tourism and industrial development in the region. This study aims to describe the natural soundscape as well as to assess the noise levels associated with shipping. Underwater so...
