How can you guys argue that you're actually preserving the wreck by taking the objects so people for generations to come can enjoy them? (I'm not pointing at any specific posts btw) Who is it that gets to enjoy them? To you guys who horde this stuff in your living room, what "generations" are you showing these artifacts to that you claim get to experiance them when you bring them back? The only people I can see experiancing them are the people in your house, unless you actually run a museum or donate the artifacts to a museum.
Furthermore, once removed they have lost all historical context. Anyone who argues that by removing the artifacts you're actually preserving their importance without recognizing the significance of an artifacts locational or positional context is simply announcing that they have no formal education in archaeology. (I have little myself, but it's enough to recognize this) If you really actually cared about preserving those artifacts you'd photograph or record what you've seen, document it, research it, and publish you're work, as many people have and continue to do. Meanwhile other divers can still experiance the wreck while its artifacts last. I know this sounds like a stretch, but that really is the only way you can argue you're helping a wreck. It's also the only way that people can continue to effectively experiance a wreck even after it's gone. Otherwise, an old tea cup sitting on your mantle is little more than an external memory of you're own ego, and a forever lost memory to any other divers who dive that wreck after you.
Yes, some artifacts won't last. But there are two major flaws in this justification. One, who are you to decide that a specific artifact won't last much longer and therefore it's ok for you to personally take it. If an artifact wouldn't last for more than another 10 years, who are you to decide that 10 more years of other divers witnessing this piece of history before it disappears isn't worth it, and you had better take it for yourself before someone else does. The point is the artifact certainly lasted long enough for you to take it away than to slowly degrade while others still witnessed it. This kind of thought often surfaces in studies of past ecological and natural resources problems where countries in the past have recognized a shortage of a resource and one country keeps using too much, so therefore the other countries tried to all take as much as they could before everyone else got it, rather than being able to agree to limit their uses. The old cod fishing issue comes to mind. It's interesting to see there are still many people who subscribe to the same reasoning though. I'd much rather see a ship with its artifacts ruined because people left them there long enough to naturally fall apart rather than seeing people do me the favor of taking the artifacts for themselves so I won't have to worry about seeing them ruined.
You guys have probably heard of a guy named Ballard. If you value anything he's done, you might be interested to know he isn't exactly on your side....

"Does that diminish it as you run along and you've had 8,000 to 9,000 objects recovered from that debris field that are not there to be seen? Does that diminish the experience? Absolutely, it does, particularly when many of these objects were not at peril," Ballard said.
Sorry to rehash a thread after a couple weeks, but this really bugged me when I saw it, and I figured bringing back a thread after a couple weeks can't be as bad as after 4 years *cough*scubamanny*cough* ;-)
