Torpedoes (mines) were scattered about the harbor. Frame torpedoes were ones that were put on wooden frames. The remains of these are a major thing that the divers are looking for.
A search was also made of the Fort Wagner battlefield which is largely if not all under water now. Washed out to sea or under rocks as a result of late 1800s jetties built in the area. Lots of magnetic material was found in the area, no doubt from the 54-day bombardment that took place in 1863, and it is the site of the 54th Massachusetts' charge as shown in the movie "Glory."
The study is to help preserve whatever is left, but also to protect new ships which are getting heavier and draw more water. It would be too bad if something from almost 150 years ago were to sink or damage something from today.
