Experimental and theoretical data are presented on the generation of seismic signals and the efficiency of signal insertion into soil and ice employing 80 cps, 10-Watt max resonant portable seismic transducers. The influence of the mechanical bulk properties and of the structural dimensions of seismic media on the transducer performance and on the preservation of seismic signal integrity is analyzed in connection with seismic communications via the weathered zone of the earth.
