I am not sure on which species you focus or what continent you are on but for European marine turtles of the mediterranean sea you could contact Archelon. The Sea Turtle protection society of Greece (=ARCHELON) is doing field work on the nests of Greek beaches, mainly on loggerheads.
Check out their bibliography at http://www.archelon.gr/eng/bibliography.php?row=row7
To contact them I´d probably try the project leaders of certain areas first - you can find their staff at "Archelon at a glimpse".
I suppose you already solved your problems with info on marine turtles. In any case you can check me researchgate or ask directly on the head the apropriate words (key words) and appear many docs on olive ridley.
