Thank you. I'll answer the second part of the question first.
With respect to Arctic ocean mapping, that is actually one of the areas for which we would be looking to groups like CHARS and other research agencies, to help fill in some of those gaps. There are a lot of gaps with mapping in general in the north. It's largely an under-mapped or unmapped region of the country, so we would be looking for additional support and projects specific to that kind of research.
In terms of the shipping itself, the fact is that the waters will be open for longer periods of time, whether due to climate change or a warming climate or what have you. The fact remains that there will be more shipping activity that's going to be required as part and parcel of what our projects will need, to get our ore to market, but our ships and our processes are held to very high environmental standards, so we would like to have research that would support this belief. Our records have indicated that we generally ship using safe mechanisms, and we would be looking for research that would support that initiative.
