A controlled source audio magnetotellurics (CSAMT) survey was conducted to gain a better understanding of the geology and structure of Neal Hot Springs and the surrounding areas. This study was conducted by students and faculty in geophysics field camps from the Colorado School of Mines, Boise State University, and Imperial College London.
This survey was designed as a multiple field reconnaissance survey. The source dipole was an electrode array made of buried and layered aluminum foil saturated in salt water; it was about 1 km long. The receiver array had a spacing of 50 m between receivers and was set up parallel to the dipole array. The receiver channels were ceramic porous pots with unglazed bottoms so that ions could penetrate the bottoms. The pots were filled with an electrode in a copper sulfate solution. Frequencies between 0.125 Hz and 8192 Hz were measured. Unfortunately the survey produced limited quality data due to malfunctions with generators used to power the source dipole.
