Abstract

Acoustic ambient noise in the ocean at frequencies of 4. 3, 8. 0, and 14. 5 kHz has been shown to be highly correlated with surface wind speed. Measurement of noise at the sea floor yields estimates of wind speed to within plus or minus 1 m/s (r**2 greater than equivalent to 0. 845) when compared with coincident surface observations. The frequency dependence of the wind speed-noise relation reported by others (17 db/decade) has been confirmed, except that separate calibrations are required above and below the speed characterizing whitecap formation. There is also some evidence of local hydrography influencing the absolute calibration.
