Abstract

The Polar Continental Shelf Project, a broad program of research in the Canadian Arctic, was started in 1959. Seismic studies were undertaken by the Geological Survey of Canada. Refraction and reflection techniques were employed in the first stages of a reconnaissance program during May, June, July, and August 1960. Certain new techniques were developed during this seismic program in the high Arctic. The crew operated from motor toboggans in 1960 but helicopters will be used more extensively in the future for a more efficient operation. Adverse weather conditions such as blizzards, low temperatures, white-outs, wind, and rain are a hindrance to operations at various times of the year. The sea ice appears to present no great noise problem to standard recording techniques. Several air shots were recorded in direct comparison with surface shots but the gain in energy level is not enough to justify using the method. The records from various locations within the Sverdrup Basin indicate that both reflection and refraction techniques are satisfactory. A cross-section illustrates the results of the 1960 program.
