For years, I've "taken" artifacts and love to dig. That said, here's my opinion:
"Protected" wrecks: I think protected wrecks are a GREAT idea provided a few things occur. First, it MUST be "protected." This means that the diving, fishing, and marine "community" in the area MUST have the mind set of "look" but don't "touch" or "take." I think certain areas of the Great Lakes and obviously Truk are excellent examples of this policy. It also means that if someone sees a diver "take" something, they REPORT it and QUICK action is taken by local authorities. This can work, but it takes involvement and cooperation. If the "protected" concept is ignored or un-enforced or, worse yet, only enforced for "non-locals," it WON'T work. Second, accessibility must be guaranteed and uncomplicated. In Truk, you don't need to go through an "application" and "review" process to dive wrecks. On the Monitor, you do. I'm cool with sending in an "application," maybe even paying a nominal fee to dive the Monitor, but beyond that is just BS. If NOAA is serious about limiting access, put it on the charter boats. "Certify" charter boats for visiting the Monitor and set up the rules. Track who goes, when they go, etc. And, don't tell me that "diving" the wreck "damages" it. I suppose pulling off plating, removing the turret and covering/uncovering the wreck doesn't "damage" it? Even in the name of "underwater archeology?" Have you looked at pictures of the Monitor lately? Yeah right....
"Unprotected" wrecks: If a salvor was granted a license by the government to "salvage" a wreck, the gloves are off. Obviously, regardless of why they granted a license or if the wreck is a "war" wreck, it wasn't important enough to the government to matter. They KNOW if war dead are on a wreck and when they still allow salvage to go ahead, they just set policy. If you've ever dived a "salvaged" wreck, you know the bottom ends up looking like a trash heap. Stuff gets moved, "expendables" (like spent BROCO rods) get left. It completely changes the "character" of the wreck. Now, "divers" (i.e., the "public") are supposed to "respect" and "conserve" this afterward? Yes, I wouldn't disturb or photograph human remains, but stay "off" the wreck after salvaged? Wrong answer.
"Underwater Archeologists:" I've had the pleasure of diving with a number of archeologists on "projects," including the Yorktown Shipwreck Project in Virginia (a British Merchant from the 1780s) and I think many of them do a FINE job. If a shipwreck has been identified for conservation and they are "actively" working it for artifact recovery, more power to them. BUT, offer the local community access in the form of "volunteer" diving, some minimal training, participation, etc. John Broadwater on the Yorktown project did this with great success and I commend him for it. Involving recreational divers in these projects will undoubtedly increase the projects profile and public access. Isn't that the point of "exhibiting" history? Unfortunately, some UAs are more about "name building" and "recognition." When a Discovery or History Channel program introduces an UA by calling him "famous" or "great" before every show, it's all about EGO. These guys are more about themselves than history. It's the SHIPWRECK that's news, NOT them. Many of these guys defend their work and policy of "no access" because "divers destroy wrecks." RIGHT. Look at the Titanic. It sat on the bottom almost 75 years without being touched. Then, the "famous" guy from WH "discovered" it, along with other "scientific" groups. Even salvors who "visited" it had UAs with them, observing their work. As the other poster noted, look at the condition of the wreck NOW. How many "recreational divers" have been on it? Give me a break...
Anyway, I'll post some more on this thread later; this topic REALLY fires me up. Pardon my RANT...
Thanks for listening...
