I think it would be much easier spotting the steam torpedo path and from what I read even that was difficult except in calm seas.

I think it would be a pretty lucky sound crew to detect a torpedo in WWII and to be able to locate and determine a reciprocal plot in time to take any effective maneuvers would be extra tough.

Has anyone come across any references from British or American ASW folks in WWII addressing this?
Yea - you'd be lucky to catch the transients. However, having 7-10 escorts per convoy tends to make you lucky. But once a torpedo is running, it's crazy to think that one of the escorts' SO wouldn't pick it up. As for specific plotting, like, i imagine that it would be hard to do because torpedoes move fast/flip across bearings. But at least you could get a crude guess about the position of the sub - and at the very least, you'd be able to initiate evasive maneuvers - snaking, etc, and potentially save ships.
