'fraid I can't download realplayer on my works machine so I'll check it out when I get home in a couple of weeks.
Not sure how 'untouched' the sea bed is though.
I've seen scans and pictures of the north sea bed after a beam trawler has been over it - scoured clean. Add to that the toxic waste grounds and slurry mountains, I would imagine many parts of the North sea are pretty much knackered.
The CBA recently published a nice book called "Submarine prehistoric archaeology of the North Sea" there's a lot of work being done, mainly off the coasts of Holland & Denmark. I'd recommend having a look at the book just for pictures alone.
There's a brief summary here
