No, I don't see any reason for not using it. The best way to use it is by triangulation to make sure that we have the exact location of the whales for reopening or closing an area.
Another thing is that I think would be important to include is the behaviour of whales. When they are transiting to their feeding ground, they don't stay in the area. If we close one area after another after another, that becomes problematic. It should be included in the way we survey these whales to know if they are feeding and aggregating somewhere or if they are just transiting to an area. That happens north of the Magdalen Islands, where we're closing areas that are not that risky. They are just transiting through.
