Abstract

Because of the ever-expanding field of activity of the geophysicist and the important contribution that can be made by seismic techniques to research in the polar regions, it is felt that the material contained in the review of the activity of the Swiss Glacier Commission, published in 1948, should be brought to the attention of American geophysicists. I have therefore prepared the following condensed translation of the paper by A. Renaud and P. L. Mercanton. I feel from experience gained in the Antarctic and on Taku Glacier (Alaska) that with the recent developments in modern portable electronic seismographs more reliable information can be obtained with these units using air shooting and at no increase in weight even for a 12-channel unit.
