May I jump in here on some of the legal things we're doing? In fact, we work very closely with the Russians in the Arctic on certain key issues. For example, the legal analysis of our approach to dealing with the internal waters of our archipelago is identical to the Russian legal analysis with respect to their archipelago. In fact, we have a coincidence of views.
We are also working with our Russian colleagues closely in sharing information and approaches to dealing with the delineation of the continental shelf. That is in our interest because we'll be going before the same committee of the UN.
The other thing may be how to think of the Arctic Ocean. There are five states around the Arctic Ocean that own their land, and there's no dispute over their land except in the case of the little ones that I've mentioned. Just think of the Mediterranean. Many vessels come into the Mediterranean. They may have interests in whatever for scientific reasons. They are never a threat to the sovereignty of either Italy on the one side, Greece on the other, or Algeria to the south.
Then the other thing to remember is that the Arctic and the Antarctic are very different. The Antarctic, of course, is ice-covered land over which there is some dispute, which many of these countries are part of an international convention to resolve. There is no dispute about land in the Arctic, which is ice over five kilometres of water.
