Yes, certainly. The propeller wounds that we see on northern resident killer whales, as I mentioned, are consistent with medium-sized vessels. These could be vessels potentially engaged in whale-watching. They could be utility vessels. There's a lot of boat traffic in that area associated with commercial fishing and fish farming.
I didn't mention this, but we also see evidence of blunt force trauma. These are the kinds of injuries that a whale sustains when it's hit by a larger ship. There have certainly been several southern resident killer whales that have died from blunt force trauma, which, we believe, has been associated with ship strikes, and some northerns have as well. Humpback whales and fin whales are also affected, so ship strikes are a bigger problem, I think. This is the take-home message that we realized some years ago.
