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 kn for a North Atlantic Ocean location near Bermuda. These results are consistent with the low‐frequency wind‐generated noise mechanism proposed by Isakovich and Kur'yanov [Sov. Phys. Acoust. 16, 49 (1970)]. [Work supported by NUSC.] |
