To evaluate the effectiveness of the CubeTechnology processing system for delineating permafrost and thawed subsurface zones using reflected-wave seismic data.
Processed multicoverage seismic survey reflection data while adjusting for surface topography and acquisition geometry.
Generated time and depth interval-velocity sections from automatically tracked velocity functions, 2D median smoothing, and the Dix equation with a 30-ms time interval.
Validated the resulting depth-domain interval-velocity models against borehole P-wave velocity log data.
Seismic interval-velocity variations demonstrated close correlation with borehole P-wave velocity logs.
Depth-domain interval-velocity sections successfully distinguished permafrost from thawed zones, revealing that thawed intervals were substantially thinner than frozen layers.
Subsurface permafrost boundaries were delineated entirely from reflected waves without requiring refracted or surface wave data.
