Analytical and Numerical Studies of a Differential Target Antenna Coupling Method for Sensing and Imaging Subsurface Targets 6 Jun 2013 | 05:31 am

In this paper, we develop the theoretical basis and carry out numerical studies on a new Differential Target Antenna Coupling (DTAC) method for imaging objects within the earth. The DTAC method uses a...

Experimental Studies and Verification of a Differential Target Antenna Coupling Method for Sensing and Imaging Subsurface Targets 6 Jun 2013 | 05:31 am

We have developed a new electromagnetic geophysical system, the Differential Target Antenna Coupling (DTAC) method, which can significantly improve target sensing and imaging capabilities compared to ...

Mapping the Geometry and Lithostratigraphy of a Paleovalley with a Time-domain Electromagnetic Technique in an Area with Small Resistivity Contrasts, ... 6 Jun 2013 | 05:31 am

The purpose of this paper is to evaluate the effectiveness of large loop, ground-based, time-domain electromagnetic surveys for modeling of paleovalley geometry and valley fills as a basis for determi...

Multi-geophysical Investigation of Geological Structures in a Pre-selected High-level Radioactive Waste Disposal Area in Northwestern China 6 Jun 2013 | 05:31 am

A potential high-level radioactive waste (HLRW) disposal site in northwestern China was investigated to determine its suitability for such a use. The site is primarily covered with well-developed meta...

Probabilistic Analysis of Ground Vibrations Produced by Vibroseis Arrays 6 Jun 2013 | 05:31 am

Vibroseis arrays consisting of multiple trucks are typically used to acquire reflection seismic data to increase the amount of P-wave energy imparted to the earth and reduce surface wave energy in the...

Evaluation of Seismic-Acoustic Analysis Methods for a Real-time UXO Monitoring System 16 Mar 2013 | 04:31 am

The Department of Defense (DoD) uses over two million rounds of high-explosive (HE) munitions per year ( Defense Science Board Task Force, 2003 ). A small percentage does not explode, thus generating ...

A GPR Agricultural Drainage Pipe Detection Case Study: Effects of Antenna Orientation Relative to Drainage Pipe Directional Trend 16 Mar 2013 | 04:31 am

Locating buried drainage pipes is a difficult task confronting farmers and land improvement contractors, especially in the Midwest U.S., where the removal of excess soil water using subsurface drainag...

Geophysical Evidence through a CSAMT Survey of the Deep Geological Structure at a Potential Radioactive Waste Site at Beishan, Gansu, China 16 Mar 2013 | 04:31 am

This paper describes a controlled-source audio-frequency magnetotellurics (CSAMT) survey conducted in August 2009 over a potential high-level radioactive waste (HLRW) disposal site in northwestern Chi...

Mapping Degrading Hydrocarbon Plumes with Self Potentials: Investigation on Causative Mechanisms using Field and Modeling Data 16 Mar 2013 | 04:31 am

Organic contaminants in ground water, such as those in landfill leachate or hydrocarbon spills, are of concern when they impact drinking water. Self potentials have been proposed as a rapid, simple an...
