Is the dredging process stripping a great degree of archaeological context from the items, or has being under the sea for so long already scrambled them up to a degree that we aren't losing all that much information by bringing them up in this way?

I get the impression that modern archaeology tends to emphasize viewing a site holistically and painstakingly recording as many details as possible, to the extent that some sites are just left alone rather than risk an imperfect or destructive excavation, so I'm curious whether anyone in the field is upset that these artifacts are surfacing as a byproduct of an unrelated civic project that isn't even trying to adhere to those standards.
