- Аннотация: This paper is an overview of the results derived from shallow multicomponent seismic (down to 200 m) within the near-surface permafrost interval. The results were 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 were generated by processing the Yy data for SHreflections. 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.
