There are plenty of wrecks to explore in the depths of the ocean in Grand Theft Auto V. These wrecks include, but are not limited to, nuclear submarines, submersibles, aircraft and many shipwrecks.

To find plenty of game debris, head east from the Humane Laboratory and Research Center. The chemical research company presumably used the ocean as a dumping ground because of the large number of sunken vehicles to the east of the humane Laboratory. These underwater wrecks are fascinating, and when you get to the bottom, you can find clues as to where they came from.
