It's both. That's the nice thing about UNCLOS, that it's geology-based; there has to be a geological connection. In other words, the rocks that form the Lomonosov Ridge, in this case, have to have, from the Canadian perspective, we would hope, a link to mainland Canada's geology. Likewise, bathymetrically you'd like to see a bridge, an apron, between mainland Canada or the Canadian contiguous continental shelf and the Lomonosov Ridge itself.
