Caption title. "September 2017." Includes bibliographical references (p. 10). “Ambient underwater noise levels have increased significantly over the past half century, largely as a result of increasing human activities in the marine environment. Marine shipping and vessel navigation activities of all types have been identified as important contributors. However, the extent of this contribution, and its associated impacts on marine species, is not well understood, and is complex to assess. There have been growing demands for government action to address this issue domestically and internationally in order to protect the marine ecosystem, and more specifically, species at risk. Most recently, in its review of the Trans Mountain Expansion (TMX) Project, the National Energy Board (NEB) found that the increase in marine vessels associated with the Project would further contribute to cumulative effects that are already jeopardizing the recovery of the Southern Resident Killer Whale (SRKW). Consequently, the Board concluded that the operation of Project-related marine vessels is likely to result in significant adverse effects to the SRKW population. DFO’s Fisheries Protection Program (FPP) has asked DFO Science to provide science advice on the effectiveness of various mitigation measures (or a combination of these) for reducing shipping-related noise levels received by SRKW. This Science Advisory Report is from the May 30 to June 1, 2017 National Peer Review Meeting on the Evaluation of the Scientific Evidence to Inform the Probability of Effectiveness of Mitigation Measures in Reducing Shipping-Related Noise Levels Received by Southern Resident Killer Whales"--Context, p.
