Thanks for the question.
Early on, when we first initiated this program, we met with industry and agreed that the science wasn't there. We identified a number of key questions that we had to work through to get ourselves informed.
The science—you're right—is not perfect. It's not exact. In the absence of having all of the answers, we have been implementing a slowdown in Haro Strait. Industry sought to lead that initiative again in the summer of 2018. That's wrapping up as of tomorrow.
We know that is reducing underwater noise. Slowing vessels down in Haro Strait has resulted in a quieter ocean in that area.
In the absence of having all of the answers, we are taking a precautionary approach and implementing mitigation through slowdowns as well as a lateral displacement.
There are actions that are ongoing.
