We're watching the situation very carefully, as you can imagine. There's a lot of talk about traffic in the north, but in fact the amount of traffic through the Northwest Passage is still minimal. To my knowledge, there was one cargo vessel that transited the Northwest Passage this year. It was a very ice-capable ship. They were in communication with us. We certainly worked side by side with them, although they navigated that route without direct assistance from the coast guard in any way.
Being in communication with mariners and knowing where vessels are moving, that's one way we're involved in protection in the Arctic. There's also a different awareness system—you might think of it that way—in the Arctic. It's called NORDREG. Ships at sea in the Arctic have to report to us in more comprehensive detail than we would require south of 60, because of the the unique operating environment.
As I referred to in my opening remarks, we do have environmental equipment deployed across the north. It's rapidly deployable and we can get it on site quickly if needed. We've implemented a system that we refer to as “cascading resources”, which means that we get the resources to the event that are closest to the event, and then we bring in other resources as needed to build the right response as quickly as possible.
Mario, is there anything you want to add to that, given your responsibilities?
