Modelling underwater sound from small vessels in southern resident killer whale critical habitat : noise reductions for increased approach distances of 400, 600, 800, and 1000 m and changes in listening... : T42-26/2021E-PDF

"Underwater noise from vessels has been identified as a contributing threat to the recovery of Southern Resident killer whales (SRKWs). As part of a coordinated effort to reduce the impact, the Government of Canada increased the whale-watching vessel approach distance from 200 to 400 m for SRKW in 2019. This modelling study was conducted by JASCO Applied Sciences for Transport Canada to determine the changes in noise levels by implementing the 400 m stand-off distance. Longer potential distances of 600, 800, and 1000 m were also assessed using the same approach"--Executive summary, page v.
