A chance encounter from an old car site led me to this, an underwater photography and wreck site for western Washington.
It has a brief narrative of a Privateer, SNV and PV-2, but the photo link to the Mariner is broken.
I'd guess, if you're really interested in those wrecks you could contact the site and see what they have.
They also say prints are available.
