The output of a small accelerometer buoy (diameter 12 cm), whose sensor axis was vertical when floating undisturbed, was recorded in the open ocean at four wind speeds ranging from 4.5 to 11.0 m/sec. Records are discussed assuming they represent the vertical component of the sea surface acceleration. Points read from the records had a nearly Gaussian distribution such that the probability of the acceleration exceeding g/2 was about 0.01. The variance of the acceleration was found to increase with wind speed at a rate comparable with that found for the mean square surface slope from other studies. Spectra of the four accelerometer records are compared with the equilibrium spectrum of Phillips. Some observations of the increase of whitecap density with increase in wind speed are described.
