Thank you for that question.
It's an area that is of great concern to us in the department. I think you've had folks from Transport and our coast guard colleagues here earlier speaking about that.
We've done great partnership in that, as Renée said, in some of our other scientific activities. We've done an awful lot of work with the Americans and with our Icelandic neighbours to do joint surveying and mapping work. Using their assets and using our assets, we can cover a lot more area.
We're not the only ones who are not as well charted in the northern reaches as we find and are used to in the southern reaches, but we are making really good progress on this. In the past, we've used vessels of opportunity. We've been using the coast guard and DND. Now we have assets from the Nunavut government that we're using, and that's allowing us to get into communities in reaches that we can't get into with our heavy icebreakers. We're getting information that's going to be more useful on a day-to-day basis for the locals.
One of the things that we're doing a lot of work on with the Canadian Space Agency and others is we're using other technologies rather than shipboard platforms. That's paying huge dividends for us, because we don't really need to try to map the Arctic the way we're used to mapping things in the southern reaches. As long as you know that you have a lot of water beneath you, it doesn't really matter. After you're over 300 metres, does it matter, from a ship's perspective, that it goes to 600? We can use technologies like lidar and other emerging techniques that are much more efficient and allow us to cover a much broader area in considerably less time—
