I would dearly like to get involved in a bit of marine archaelogy, really - projects like this and the Mary Rose are quite interesting, and I could do with an excuse to get my drysuit on more often.
ISTR they do a summer course down at Southampton or Portsmouth on the subject - you know anything about that DM?
Oddly the wikipedia article on HMAS Sydney was up a few weeks ago as the featured article (before the discovery). Was the first I'd read about it - very curious engagement. Why did the Sydney get so close? Lots of questions may be answered as the salvage/investigation goes on.
