>The geology is not going to give much if anything in the way of megaliths
Probably true, but you never know. We can live in hope. Though the Cornish and Irish coasts most likely offer a better chance of stoney stuff than the North Sea does.
>the people of the time when it was dry land would have been nomadic
Depends on how far from the present coastline you go I guess. I'm under the impression that there were still some fairly mobile folk kicking about in the neolithic. Admittedly, my Northumbriocentric perspective probably skews my view towards thinking that the meso/neo transition was longer than it may have been in other areas, but I do think that this underwater stuff could provide genuinely new information. Especially in expanding on the really old stuff. Maybe they'll dredge up some evidence about that alleged seaborne activity along the ice sheet.
What Fitz says about offshore dumping is so very true though, as is the point about erosion by currents. I've watched the ship that takes the aluminium smelting effluvia go about it's business of concreting the surface of a patch of the seabed off the Northumberland coast. Maybe in a strange way, this could protect sites from the erosion of currents. In ref to the shifting of the sands, the beaches up here are very different from the way they were even just 30 yrs ago. Yet still, in situ evidence of neolithic settlement has been found off the mouth of the Tyne, despite millenia of shifting currents and centuries of industrial shenanigans. Best think positive eh?
Cheers for't links PH, they look most interesting too.
