20: 13 And the sea gave up the dead that were in it, and death and hell gave up their dead that were in them; and they were judged every one according to their works.
The corpses that fell in the sea are as dissolved into elementary parts as corpses fallen into crematoria. Unless very recently fallen into the sea. If the one can give up its dead, so can the other.
Here is a thing from Solomon, Ecclesiasticus 22: 13, though:
The mourning for the dead is seven days: but for a fool and an ungodly man all the days of their life.
