Abstract:

This report describes advanced classification processing of TEMTADS 2x2 time-domain electromagnetic data collected at Anderson Air Force Base, Guam. Black Tusk Geophysics processed approximately 1200 cued interrogations to recover estimates of intrinsic dipole polarizabilities for detected sources. Quality Control QC of the inversion results flagged high-likelihood TOI anomalies and failed bad models and inversions. In addition, estimated polarizabilities were used to identify potential novel targets of interest TOI at the site via cluster analysis and comparison with a comprehensive polarizability library. One TOI was found in the training request.
