Detailed seismic refraction analysis of ice-bonded permafrost layering in the Canadian Beaufort Sea

The recent application of high-resolution, multi-channel, seismic reflection techniques in the Canadian Beaufort Sea has yielded better sources of data for refraction interpretation of ice-bonded subsea permafrost. This paper discusses some examples of this work which demonstrate the structural detail which can be obtained. A seismic line transecting the Beaufort Sea shelf has been interpreted with data spacings of 125 m. The results confirm early results of Hunter et al. (1978) and show detailed structural and velocity variations of ice-bonded zones.
