A numerical model for ocean ultra-low frequency noise: Wave-generated acoustic-gravity and Rayleigh modes
International audience The generation of ultra-low frequency acoustic noise (0.1 to 1 Hz) by the nonlinear interaction of ocean surface gravity waves is well established. More controversial are the quantitative theories that attempt to predict the recorded noise levels and their variability. Here a...
