Total radio-activity, potassium, and thorium, recorded digitally on magnetic tape were used to calculate an average snow-water equivalent for 16 km sections along each flight line. The air-borne results were compared with the measurements from 40 existing snow courses and ten experimental courses established along the flight lines"--Abstract.
