I can't speak for the game, but in real life a submerging submarine depending on sea and light conditions often left a a persistent swath of bubbles, foam, residual oil and disturbed water, that served as a handy visual marker from the air on where the sub had left the surface.

Radar.

It has a longer range and can detect such a small target like a periscope or snorkel mast, that you're really not as hidden as you think...
