Man-Portable Simultaneous Magnetometer and EM System (MSEMS)
Abstract
EM61 pulsed induction sensors and total field magnetometers are the two primary sensors employed for MEC detection on formerly used military properties. While these two sensors have a broadly overlapping performance envelope, each sensor has unique strengths. Unfortunately, co-deployment of the two sensors is normally impossible due to the active nature of pulsed EM which creates noise on any nearby magnetometer. A prior ESTCP project developed the technology needed to co-deploy these two sensors through the process of interleaving (sampling the magnetometer between the EM6l's pulses when the EM61 is quiet), and deployed that technology on a vehicular platform. Under this project, a Man-Portable Simultaneous EMI and Magnetometer System (MSEMS) was developed. The interleaving hardware was made smaller and lighter to enable man-portable deployment. A box with standard interfaces was developed that allows any geophysical contractor with EM61's, total field magnetometers, and GPS equipment in inventory to connect them to the interleaving hardware and concurrently collect magnetometer and EM61 data.
