That's a good question. Maybe I should ask you to give me your definition of custodial management. I have several, including some from people around the table who have done pretty well according to these definitions.
That certainly is part of it. We intend, under the law of the sea, to try to extend our continental shelf. We said we would do that. We have to make our submission by 2013, I believe. We've asked the department not to wait until the last minute and then rush to make changes. We're trying to move as quickly as we can.
Extensive mapping has to take place, but while we're doing that, the mapping can be used for a lot of other things. We're trying to open up the north in particular, as you know. We need to know more about the passageways. We need to know more about the geology under the water, for all kinds of possibilities. We also need to know the exact extensions.
I think in our preliminary mapping of the Grand Banks area we really took in more territory. The shelf extended a bit farther than originally thought, according to limits, which also then gives us control, of course, over anything on or under that seabed as of today. That makes mineral exploration more viable and extensive.
It's beneficial right around, but what we have to show are the limits off the continental shelf, the maximum limits according to all the rules, as we submit to the law of the sea for complete control over that territory. If we want to push for control over the waters over it, that has to be part of the equation.
