Yes, and I appreciate that it's a complicated set of formulas that determine this. The first one is a definition of how deep the continental platform really is underwater. That's a part of it, because at some depth it's considered too deep to be part of the platform. The second part of the equation is how thick the sediments are. So it's the combination of how deep the water is and how thick the sediments are that tells us how much distance we can go out from the continental shelf's sharp drop-off to claim additional territory. That's the simple formula.
The complicated part that I think you're referring to is that there's a possibility that the land mass extends away from the continental shelf we would draw as a very steep drop-off. This is the question about things like the Lomonosov Ridge and whether it's physically connected to Canada's land mass. If it is, then you can use that formula of distance and depth and thickness of sediments. The geology here sets the context for that discussion, but it doesn't necessarily answer the question itself. We have to make other measurements to try to prove that it's connected to the land mass.
