Impact of ship noise on the underwater soundscape of Eclipse Sound in the northeastern Canadian Arctic

Open Access Research Article 2023

Jones, J.M., Westdal, K.H., Ootoowak, A.J., Wiggins, S.M., Hildebrand, J.A.
Study estimates contribution of shipping on natural soundscape of Eclipse Sound in Canadian Arctic. Noise emitted by ships is quantified by vessel type, including three cargo ship types, passenger ships, pleasure craft, and icebreakers. Individual ship transits through the region introduce transient noise at frequencies from 20 kHz, with durations lasting from a few minutes to >6 h. The impact of ship noise on the soundscape is significant, resulting in increases in sound levels by 15 to >30 dB when ships are within 10 km and measurable ship noise below 200 Hz at distances of >50 km..
