Thanks for that Martin, I'll be very interested in reading about what you see. I hadn't heard of Seasearch before (
www.seasearch.org.uk for the uneducated like me!). They're at the LIDS (stand 1048 - near the Carribean Village!) and they're doing a presentation so I might go along at find out some more.
Sterny, you fancy having a go at IDing some stuff on the Sussex coast sometime?
Cheers
Jonathan
