Cool, I just wish they would show a shot of: HERE WITH WATER and then WTHOUT
I think most of them would be fairly unimpressive because they don't break the ocean surface at all. The Monterey Canyon one, for example, has the coast of Monterey visible in the image, but I think that was the only one that had above-water visibility.
I'm just gonna watch the 2 hour show on Nat Geo in about 15 minutes.
I've seen it, but those idiots at NGC managed to switch the last part of the documentary out for some cheesy movie... So I missed the last part =_=
The landscapes where quite impressive though. If you want a look at 'without water' maps, try and look for geological maps depicting the world, or parts thereoff about 12.000 years ago. During the last Ice-age, the water levels where a good 100 meters lower. Imagine walking from the UK to mainland Europe (actually, the UK WAS mainland Europe, even though both names didn't exist yet :P).
