Abstract : The Vehicular Simultaneous EM! and Magnetometer System (VSEMS) was deployed at the former Kirtland Bombing and Gunnery Range during the fall of 2006 as part of the ESTCP Wide Area Assessment Pilot Program. Magnetometer and EM61 Mk2 data were concurrently acquired on pre-planned transects (generated by Visual Sampling Plan on the basis of existing data from a Conceptual Site Model) to bound the extent of known bombing targets and assist in discovery of new ones. Data were analyzed overnight to provide inversion results (location and depth estimates) for objects of interest in the data. These data were used by another contractor, and by the ESTCP program office, to refine the CSM and to specify new transects. High-resolution 100% geophysical survey data were also acquired in areas located radially outward from bombing targets to determine anomaly fall-off. and in areas that were flagged as being of interest after interrogation of data from the airborne sensing layers. 193 acres of transects and 159 acres of 100% geophysical survey areas were acquired, for a total of 352 acres. 9969 anomalies were extracted from the data.
