I'd like to answer that.
I just want to mention that this is the last day of the International Polar Year. The funding that flowed into that research activity is winding down, so there's an opportunity there to continue some of that incredibly good work. Some of it involves surveillance, and some of it also involves the potential for enforcement that you're talking about.
In terms of what you can actually do, I agree with my co-witness. There is very little you can do once oil gets into ice-covered waters in massive quantities. You have to treat it like a very major human catastrophe, like a nuclear bomb going off or something. There is very little you can do about that.
