I'm certainly no expert on maritime disasters but I would think that if a ship goes down, particularly as a result of war, there may be significant numbers of the crew trapped inside. As to cleaning up the oceans, I'd love it if someone could do some back of the napkin type calculations on how much pollution is caused by these sunken warships as opposed to commercial shipping or industrial runoff. I would assume this is negligible in the grand scheme of things.
