This summer, starting in August, the industry will be conducting a trial to assess the impact of a speed reduction, specifically in Haro Strait, which is the most sensitive of the ecosystems for the southern resident killer whale. It searches for food and mates there. That trial will run for a two-month period and the objective of that trial is to measure the overall change in sound in that part of Haro Strait to see if a speed reduction alone can have a positive impact.
