Get this from a library. Aeromagnetic map and interpretation of magnetic and gravity data, Circle quadrangle, Alaska. [John W Cady; Florence R Weber; Geological Survey (U.S.)]. An aeromagnetic survey is a common type of geophysical survey carried out using a magnetometer aboard or towed behind an aircraft.

The principle is similar to a magnetic survey carried out with a hand-held magnetometer, but allows much larger areas of the Earth's surface to be covered quickly for regional reconnaissance.
