Abstract

Summary

This paper provides an overview of the results derived from shallow multicomponent seismic (down to 200 meters) within the near-surface permafrost interval. The results have been obtained using 3C receivers, vertical (Z) and horizontal (Y) impact excitation, and PP, PS, and SH waves. The most reliable results for the study area have been generated by processing the Yy data for SH-reflections. The close similarity between SH- and PP-wave spectra, coupled with much lower (by a factor of 4 to 5) velocities, explains the high resolution of non-converted shear wave images in the shallow subsurface intervals.
