It's convenient that the game lets the observation scope do this, but not realistic once you start going deep.

Well, I used to go SCUBA diving (admittedly, in the clearer Pacific), and I can distinctly recall easily seeing the bottom of the dive boat when the light conditions at my depth were pretty low. It's the kind of thing where you can't see much laterally because of low light, but you can see things silhouetted against the bright surface.
MANY marine predators take advantage of this fact.
I suspect that you can see the shadow of a surface ship when it's directly above you much easier than you could see to the side. |
