METHOD AND APPARATUS FOR CONDUCTING GROUND MAGNETIC SURVEYS

摘要

"METHOD AND APPARATUS FOR CONDUCTING GROUND MAGNETIC SURVEYS" A method and apparatus are disclosed for conducting ground or near ground magnetic surveys in which the magnetic field measurements of the earth's total field, a component thereof, or a combination of components thereof, are made at continuous or near continuous (less than 20 feet intervals) measurement intervals. These measurements are recorded in analog or digital format by the apparatus which may include a corresponding chart recorder, recording on chart paper, magnetic tape or any appropriate recording device. The device includes manual switches for advancing the chart, making a recording, making a fiduciary mark and for reversing the polarity of recording of the reading from the magnetometer.
