I agree that the articles I linked to were not from peer-reviewed journals; generally when one performs "trivial googling", you don't get that kind of material. The article which most of these stories rely on for scientific credibility is from Nature, and is only accessible with a subscription. However I found this link:
through more googling which carries the meat of the paper in it.
I would also note that I was not claiming either side was correct; merely that more investigation is required and that the Navy seem to be solving the problem with a very large hammer when one is not necessarily required.
