This is part of the USS Arizona sunk as one of the many on December 7, 1941 as seen from the Memorial that is over the top of it. The ship had been filled with 1 1/2 million gallons of fuel the night before. The oil slick you can see in the picture is a seepage still coming from it - 9 1/2 ounces leaks daily.
omg. that's crazy that there's still fuel 80something years later
I suspect the leakage is oil from the engine casing, but I might be wrong
probably not fuel oil anymore but residue oil from fuel tubing and fuel pumps and and slowly rusting storage containers for lubricant oils.
