> Interesting how nearly all the sites are so darned close to the shore.

Most of the sites do not have a known location. Or at least, not known to the people producing the map. Click a few markers and you will see lots of "Unknown Location" or "Off $location" which usually means the dumping ship left from that location.

It is true that many munitions were dumped close to shore, but there is a certain amount of making the map as scary as possible going on.
