The one-dimensional continuous wavelet transform is applied to the analysis of seismoacoustic data. The data consist of received signals, due to an impulsive source, measured by a triaxial seismometer. The wavelet transform provides a time-frequency decomposition of the signal, which in turn yields information about dispersion and arrival times of the various propagation modes. The primary goal of the analysis is to explore methods for extracting information from the time-frequency representation. The use of the wavelet transform will be complemented by modeling efforts. In particular, the different modes of propagation, estimating geoacoustic parameters, and localizing the source will be identified and analyzed.
