I was out on the Rudy with Andy Beaver many times and am still in contact with him, even though he has retired from NOAA and in the midwest.
I work with the CT State Archaeologist and the State Horstorical Office and got the raw data from Andy and the TJ when she was up here. So, I have a fair idea of just what they scanned, and I have run a sidescan a few times and know just how hard it can be.
My comment was that they Only found 5 wrecks on thet run because they hit a wreck. Not that they did anything wrong. In fact they are very carefull and their biggest problem in the Sound was not being able to run at night, there were just too many lobster pots to snag the tow fish for night survey. This make the planned Sound surveys twice as long and much more expensive. Not that any surveys are being run in the Sound lately with all the storm damage survey work to be done down south in the Gulf.
