Has any of this changed?

Did "Chemistry" class ever explain how the ocean has different
layers of density that cause the sonor problems that are well
documented by submarines? I would think using your logic that
it would be one uniform solution. ????

Some of those are thermoclines, regions where temperature (hence
density) changes rapidly in a short range of depth. These also occur
in some freshwater lakes during the summer, are visible with sonar.

And the same thing "cant" happen in an undisturbed battery.
