This report discusses the implications of underwater noise generated by present and planned projects along the North and Central Coast of British Columbia. Managed by Mike Ambach from WWF-Canada, it explores key projects such as LNG developments and shipping trends, assessing their potential effects on marine ecosystems. Emphasizing the need for noise mitigation strategies, the report encourages a shared understanding of future scenarios involving vessel traffic and acoustic impacts in a rapidly changing environment.

  19. Discussion How to plan around (noise) mitigation in a rapidly changing environment? What is essential to know about proposed/new vessel traffic now, and how can that flow of information be facilitated?
