It's the same thing, I would say, for both the domestic.... I'll speak a little bit for them.
Aside from the ferries, there are also the cargo domestic vessels and the international domestic vessels. On the west coast, there is a program for training marine observers on board those vessels. They report their sightings in the same manner, as is the same with any international vessels coming into the waters having information to report.
My last point is that some of our members from the international fleet are doing studies to compare the noise footprints within their fleets. That is also being shared with Transport, to feed their knowledge gap.
