Advanced EMI Sensor Demonstration at the Central Impact Area, Camp Edwards, MA
Abstract
Classification using the MetalMapper and TEMTADS 2x2 advanced electromagnetic sensors was demonstrated at the Central Impact Area (CIA) of Camp Edwards on the Massachusetts Military Reservation, Cape Cod MA in 2012. This report summarizes the results of that demonstration. Classification is a process used to make a decision about the likely origin of a signal. In the case of munitions response, high-quality geophysical data can be interpreted with physics-based models to estimate parameters that are related to the physical attributes of the object that resulted in the signal, such as its physical size and aspect ratio. The values of these parameters may then be used to determine whether the signal arose from a munition or harmless clutter. \With reliable classification, only the munitions need to be removed from the site. Classification is motivated by the need to perform munitions response more cost-effectively so that limited clean up dollars can be used to reduce real risk on munitions-contaminated sites sooner. The demonstration at Camp Edwards continues the practice of production geophysics contractors collecting and analyzing advanced sensor data using the MetalMapper and TEMTADS 2x2. One purpose of the demonstration was to train production contractors in the analysis of data from these advanced sensors. The objective of the ESTCP demonstration was to detect and correctly classify TOI on the site with emphasis on removing potential groundwater contamination sources. Classification based on cued MetalMapper and TEMTADS 2x2 data was used in Phase 1 of the ESTCP demonstration at the Central Impact Area of MMR to successfully identify 95% or more of the TOI and eliminate up to 75% of the clutter.
