Absolutely, yes. There are mobility challenges in both polar regions. Certainly, the climate in the north in the summer is much more favourable to doing Arctic field work than it is in the southern summer.
I think there are a number of challenges. Access is certainly one of them. The sheer geography, the size of these areas, and the wide range of investigations that need to be accomplished to fully understand these environments, to make sense of that new information, are major challenges.
Prior to joining the commission, as a research scientist and science manager in Natural Resources Canada, I had the opportunity to work collaboratively with many international partners, all of whom hold Canada and the Canadian research enterprise in very high regard. They're always pleased to partner with Canadians, and this often leads to opportunities to work internationally and to share best available knowledge, to learn from one another and move ahead in a global context—the understanding of the functions of our planet and the creatures that inhabit it.
