This thermal layer idea is great. It may or may not be there, and the depth will vary when it is present. You have no way of telling, just as the WW2 skippers had no way of knowing.

Not sure about early war subs and U-Boats but in reading about late war sub operations in The Pacific they certainly had a bathythermograph they used to measure and monitor temperatures outside the hull. Often they'd know in advance what to expect because they'd be diving in that area before a contact was made.
