Hi!
It is generally not possible to perceive objects beneath the surface of the ocean except in conditions where the waters are particularly clear, and when the sunlight and viewing angles are favorable.
The picture of USS Chicago that Hitman posted illustrates that it is possible under certain circumstances to see down into the water; however, the fact that it is a highly unusual photo also makes it "the exception that proves the rule."

The picture of Chicago was taken in the Pacific, near Malaysia, but it's certainly not that exceptional. In the Mediterranean the water is also clear enough, and in the Atlantic it might be a bit more darker, but still a submarine can be seen at periscope depth from the air. However what changes is A) The depth at which it vanishes (Lower in the Atlantic) and B) The angle at which it is visible (In the Atlantic you pretty much need to be just above it to be able to see it).
Cheers
