Bird maneuver, the rotation of the coil‐carrying instrument pod used for frequency‐domain helicopter electromagnetic surveys, changes the nominal geometric relationship between the bird‐coil system and the ground. These changes affect electroma

A study of the geoelectrical structure of the central part of Piton de la Fournaise volcano (Reunion, Indian Ocean) was made using direct current electrical (DC) and transient electromagnetic soundings (TEM). Piton de la Fournaise is a highly active

A technique for minimising the calibration errors in helicopter electromagnetic data (HEM) is developed. The method is based on resistivity-depth information obtained from auxiliary geophysical data at locations scattered over the survey area. The te

The procedures used to calibrate helicopter electro-magnetic systems are analysed to determine the errors produced both by mispositioning the Q-coil and by the effects of conducting ground at the calibration site. In general, errors produced by mispo

Transient electromagnetic soundings were used to obtain information needed to refine hydrologic models of the San Luis Valley, Colorado. The soundings were able to map an aquitard called the blue clay that separates an unconfined surface aquifer from
