A method and apparatus are disclosed for signal-to-noise optimization of seismic-trace signals during seismic prospecting utilizing plural initiations of a low energy surface seismic source. The method and apparatus optimize signal-to-noise ratio by vertically stacking, that is, summing, inverse power weighted seismic-trace signals from each of the plural initiations wherein the exponent used for weighting is selectable for optimizing the signal-to-noise ratio of the composite seismic-trace signal. The range of exponents provided is correlated to the range of ambient noise, including nonstationary noise, commonly encountered during seismic prospecting, especially vibroseis seismic prospecting, for the purpose of optimizing the quality of seismic-trace data.
