With respect to slowing vessels down, as you stated, there's no one size that fits all. Vessels can in fact become louder if they are slowed down, depending on the type of vessel. I know that BC Ferries and other shipping lines have done a lot of research around better understanding what their fleets are and having a fleet perspective.
Through the ECHO program we've learned about a performance objective. If we understand the overall desired level of underwater noise that we're trying to achieve, then different vessels can approach it with different speeds, depending on what works best for that vessel type. Through the Haro Strait slowdown this summer, we asked container vessels to slow down to 14 knots and we asked bulk carriers and others to slow down to 12.5 knots. By doing this differential speed, when the whales were present, vessels were able to participate when and if it was feasible for them and it was easier for them to achieve those speeds.
We are undertaking to have results, and we'll be analyzing the data. We'll have a report toward Q1 2019, but our objective all along has been to take the same speed reductions we had during the trial in 2017.
