I think each layer of the interior atmosphere of a gas giant is composed differently - like, it’s not as simple as “the hydrogen layer floats on top of the helium layer”, but that gives the general idea, right? If you find some way of shining a light or radio wave that passes through one layer and reflects off the next, you could map that boundary. I can only imagine the turbulent boundary between the two layers being one of the most beautiful sights imaginable. Endless noise on a cosmic scale, patterned first by fluid dynamics, then successively by other phenomena of physics.
