China have discovered a new nonacoustic way to detect submarines
It's 3 to 6 orders of magnitude more sensitive than MAD
As water move around the submarine at different speeds, bubbles form on the surface
During cavitation process the bubble emits EM signal in the ELF range

The electromagnetic emission in the extremely low frequency range, can efficiently travel through water and the atmosphere for a very long distance.
When picked up by air assets, they can determine the distance and direction of the submarine.
