2003 Airborne Geophysical Survey at Pueblo of Isleta Bombing Targets, New Mexico, February 14 February 26, 2003 (Rev 1)
Abstract
This report describes the results of a low altitude helicopter geophysical survey performed by U.S. Army Engineering Support Center, Huntsville (USAESCH) and Oak Ridge National Laboratory (ORNL) over areas contaminated by unexploded ordnance on Pueblo of Isleta Nation lands in February, 2003. The purpose of the survey was to evaluate improvements to a multi-sensor magnetometry system for ordnance detection. A survey was carried out at area S-01 on the Pueblo of Isleta where the Department of Defense previously had conducted weapons tests and bombing exercises. Area S-01 comprised about 660 hectares (1630 acres). The average rate of coverage for site S-01 was 39 ha/hr and the average survey speed was 15 m/s. The average distance between the actual locations of the excavated items and the predicted locations from helicopter anomalies was about 1 m. Noise levels of magnetometers fell within acceptable levels, usually less than 1 nT. At site S-01, 78% of all non-seed ordnance items (double-blind test) and 46% of seed items (blind test) were detected.
