Statistical data on geophysical activity in 1980 are gathered from two survey questionnaires mailed to more than 500 companies, contractors, government agencies, and institutions throughout the free world. One questionnaire was the original form which was designed primarily for reporting petroleum activities, and the other, an alternate form, was designed to facilitate reporting of nonpetroleum geophysical activities. We have attempted to gather data from all users of geophysical techniques in the areas of petroleum, mining, geothermal, and groundwater exploration and from those who employ geophysical methods in engineering, oceanography, and research. In general, response to the survey was good. However, we feel that there are new users of geophysical methods we are not reaching. If you did not receive our 1980 questionnaires, please let me know so we can include you on our mailing list for 1981. (As always, data submitted by individual organizations are held strictly confidential.).
