You know, I don't think it's as high as people think with regard to dark vessels in this area. It doesn't mean that it doesn't happen, but those are really for nefarious things they are going to do. I suspect that if we have vessels that are transiting from a trade perspective, from a commerce perspective or from a pleasure perspective, they're not going to necessarily turn off their AIS.
We also monitor through satellite. It's not just AIS. We can track vessels through various means. We have AIS transponders, we have satellite and we have other means that we're able to track with, as well as regular check-in points from radio contacts so that we have a sense of where that vessel is. Within our marine communication traffic services centres, they also have predictability with regard to where those vessels may end up. All of this is in the process to at least try to manage the vessel traffic in the area.
