Perhaps I could ask another question in an area related to mining.
Before you mine something, generally you have to map it. There are a few outcrops in history where things have been found, oil has popped through the ground, and you can see mineral deposits on the surface. Now, in the supplementaries it's approximately, I believe, $12 million more. I could be wrong on those numbers. More appropriations have been added for geoscientific data, the term one of the notes here uses, and of course $100 million in the future for geoscience programs. Could you comment both on the need for the extra appropriations, and in the broader sense on the vision you have for the larger geoscience program? Could you also specifically note anything involving limits of the continental shelf and how money is being spent for that? Are we allocating enough for that, particularly with the Russians' interest?
