"Between August 20 and October 31, 2018 the Vancouver Fraser Port Authority andTransport Canada led a voluntary program where all outbound deep sea vessels and inshore vessels (tugs) in a portion of the Strait of Juan de Fuca were requested to shift their outbound tracks southwards, and further away from areas of critical importance to the endangered Southern Resident Killer Whale (SRKW) population. The main goal of this study was to investigate the efficacy of lateral vessel displacement to reduce the impact of underwater vessel noise on SRKW at three locations off Port Renfrew, Jordan River and Sooke"--Abstract, page iv.
