U-boaters were definitely aware of the thermocline and more than one has mad reference to ducking under it to escape detection. This was especially noticeable when the enemy was using ASDIC, as thermal layers sometimes completely blocked out "the pitter-patter of raindrops" on the ship's hull.
FYI for those not familiar, ASDIC was often reported as sounding like rain or gentle tapping.
I would be curious to get a definitive answer as to whether or not this feature does in fact exist in SH3...
Cheers,
