Abstract
Ship traffic has been increasing in the Canadian Arctic, and with it, underwater noise. Underwater noise from ships is known to cause a number of impacts on marine animals, and is therefore an important concern in the Arctic. This report is part of a larger study funded by the Nunavut General Monitoring Plan. In the report, we examine ship traffic in the Kitikmeot Region and Lancaster Sound, Nunavut (Northwest Passage – southern route), and model the noise levels caused by all of the ship traffic between 2015 and 2018. Ship noise peaks in August and September of every year analysed. Modeled ship noise was highest within Eclipse Sound due to the large volume of traffic within that area, but was also high south of Victoria Island in Dease Strait where ships are spatially constricted to following a relatively narrow route. Future work should be carried out to validate these modeling results with acoustic measurements in different parts of this region. Future work should also examine the overlap between ship noise and various marine animals, such as narwhal and beluga, to estimate the exposure of these animals to ship noise.
