I'm hoping that perhaps someone might be able to fill in some blanks for me.
Back in the 70's I took diving classes, with my father (who was a NAUI certified instructor) teaching. During the class room materials at one point (I think it was there, and not at a Downward/Inward to the sea, or something similar conference held in D.C. area) we watched a film that was basically looking back at the environmental impact many years later of some Japanese war ships that had been sunk while sitting in an island harbor area.
I seem to recall that the Japanese ships found themselves caught within a horseshoe of islands that protected them on the sides, but wound up keeping them in place where they were eventually sunk in a nasty battle.
The film that I recall watching involved diving / mini-subbing down to the ships to check on their integrity as well as investigating the sealife in the area to determine the impact that the oil / petro and other materials in the ships had. I believe, but am not certain, that the film was done with sponsorship by an organization like Mobil or Shell oil, but I could be wrong in that regard.
Anyway, I'm trying to figure out what battle this may have involved, and if possible, what film I may have seen.
I wish I could remember the ship names (which would help figure out the battle obviously), or the island names, but again, I'm hopeful that someone may be able to help me out here. Even if you don't know the exact ships I'm thinking of, I might learn something along the way.
