"The influence of atmospheric pressure on the density of sea water and on the seabed would I think be so miniscule to be completely insignificant."

You might well be right, but then you could say the same about typhoons over land. Its just a hypothesis after all. I can't be arsed to trawl through the literature to find out more or what's changed since the paper's been published, so I'm out.

Also, despite the fact the paper is intriguing, none of this is as interesting as dinosaurs ;-)
