Abstract:

Ambient noise models which assume no significant wind-generated noise mechanism in the 5- to 100-Hz frequency range predict a notch in noise levels, between shipping and microseismic noise, at approximately 10 Hz. Data are presented for the frequency range 3-200 Hz that show that this notch fills in at increasing wind speeds and is entirely eliminated above 35 knots for a North Atlantic Ocean location near Bermuda. These results are consistent with the low- frequency wind-generated noise mechanism.
