As with much of the nation's infrastructure, people are becoming more and more aware of the condition of levee systems in the United States. The media cast a spotlight on the New Orleans levee failures during Hurricane Katrina in 2005 and the floodin

Over the past 30 years, geophysical methods have assumed a much more prominent and integral role in many investigations where subsurface features have environmental and engineering importance. In fact, the field once referred to as “environmental a

Over the past fifteen years, notable progress has been made in the performance of airborne geophysical systems for mapping and detection of unexploded ordnance in terrestrial and shallow marine environments. For magnetometer systems, the most signifi

Airborne geophysical sensor systems using boom-mounted configurations now play an important role in characterizing ordnance-contaminated defense sites. Most of the systems developed to date have been magnetometer systems. These have proven ineffectiv

The concept of complexity is a popular and contentious topic. Just what is complexity? What does it mean to 'think complexly'? This paper addresses both of these issues. Complexity thinking is impossible to define with any precision as it deals not o

Over the past 10 years, several advances have been made in helicopter geophysical systems for mapping and detection of unexploded ordnance (UXO). Earlier total-field magnetometer systems for this application invoked a novel boom-mounted sensor design

In April 2007, Battelle demonstrated two new airborne vertical magnetic gradiometer systems for unexploded ordnance (UXO) mapping and detection at the Former Kirtland Precision Bombing Range, New Mexico. The primary benefit of vertical gradient is th
