Explosives dumping area near the spill area

Slightly off topic, but I was checking out a nautical map of the spill area and found this eye opener. Some of you offshore fishermen might already know this, but there are two "disused" explosives dumping areas off the coast of Louisiana, one very near the rig accident and another just to the west of that. Did a little googling and found out something even more amazing. The US (and other countries) dumped munitions (including German ordinance and chemical weapons like mustard gas) into the sea from at least the '40s until the 1970s, including the Gulf of Mexico.

Now, do you feel any better?

<edit> and an unexploded torpedo...didn't see that one Tigerholic.
