I was stationed on a 688 class submarine in Pearl Harbor
for 3 years and I do not recall ever finding or charting anything on
the bottom. When transiting between islands we would stay fairly
far from the bottom and are not very concerned with things on the
bottom.  It also requires use of active sonar to find things on the
bottom, which SSNs don't like to use very much.
