Thank you.
My next question is for Elizabeth Kingston with the Chamber of Mines. You talked a little bit about marine shipping and, especially with the advent of climate change and the lack of multi-winter sea ice in the Arctic region, the increase in shipping in the Arctic and the fact that we can continue shipping products throughout the Arctic in an environmentally friendly way with a very small environmental footprint. Can you just talk about that a little bit vis-à-vis the amount of ocean mapping that's done, where the shipping lanes would go, and if your group has been working with CHARS and other groups on that?
