Does anyone know if there is a sensor for the topography of temperature in bodies of water? I have no idea what the proper terms would be. I don't mean a thermometer, but something that can map it in 3D over a wide area as though it is terrain.

I might be wrong to assume submarines on the open sea might have this to avoid turbulence? But I'm asking about something that would be consumer level and could be integrated into fish finders. I know, weird.
