Thanks, Mr. Chair. I appreciate the time constraints.
Professor Charron, you mentioned that one of your four “c”s was commerce. You said there are commercial opportunities in the Arctic region. Can you tell us briefly what you think are the two most significant commercial opportunities? The other thing you mentioned, which I didn't quite understand, was that the U.S. is our greatest challenge. You said that came out of the academic conference you attended, and I wonder if you could expand on that a little and tell us what you mean by that.
