Some seismic, electrical and thermal properties of sub-seabottom permafrost samples from the Beaufort Sea
Ultrasonic compressional and shear-wave velocities, complex resistivity and phase-angle relation-ships, and thermal conductivity have been measured in the laboratory at subzero temperatures on sub-seabottom samples of sand, silt, and clay permafrost recovered from the Beaufort Sea. The physical prop...
