SIMRES Ambient Noise: Observed Differences in the Underwater Noise Soundscape Before and After Implementing the 2019 and 2020 Saturna Island Interim Sanctuary Zones
December 2021 — British Columbia, Canada
Client: Transport Canada Innovation Centre
An analysis of underwater ambient noise levels from recordings previously collected at two locations in Boundary Pass over a three-year period to compare differences in the underwater soundscape before and after implementing the 2019 and 2020 Saturna Island Interim Sanctuary Zones. Vessel traffic was prohibited within the Zones to reduce acoustic and physical disturbance from vessels in Southern Resident killer whale foraging areas.
