The specificity of seismic soundings in frozen ground is defined by the features of the permafrost-related wavefield. According to years-long experience of the authors, shear-wave surveys with the use of the SH phase are an efficient tool to study unfrozen layers (taliks) above permafrost and the subsurface structure. Joint use of compressional and shear velocity data is workable in estimating the state and properties of frozen ground.
