Microseisms (seismic surface waves) in the frequency range of 0.1--1 Hz recorded at Palisades, New York, are compared with microbaroms (infrasound) in the same frequency range recorded simultaneously. Both are thought to be generated by interfering ocean waves, and the question addressed is how often does their comparison imply that they have the same source. Compared were their approximate regions of fromation, the formation conditions (both meteorological and oceanographic), amplitude variations, and frequency spectra. It is condluded that for the signals recorded at this location the two phenomena appear to have the same ocean wave sources 2/3 of the times and at least some of the remaining times one of the signals is prevented from arriving owing to propagation difficulties.
