Prob a decent amount, but not because they were at the site of the explosion, but because an explosion will send a concussive sound wave through the ocean much farther than air. Found this assessment by DOI online and it has some equations and studies done on all sorts of turtles, fish, and marine mammals[1]. I think the largest explosions they are looking at are <1K lbs, this test was 40k lbs.
