c. Integrating a non-magnetic signature low light or acoustical line scan camera 

 with the magnetometer might provide real-time imaging of targets, providing 

 additional ground-truthing. 



d. Commercially available survey planning and tracking software would 

 improve the efficiency of the survey and assist in determining the confidence 

 limits for the survey coverage. 



e. Positioning improvements to better control the magnetometer tow and 

 document absolute position are also needed to be able to assign confidence 

 limits on survey coverage. 



/ Some improvement to the magnetometer system is warranted to ruggidize the 

 tow for continuous operation and streamline signal post-processing. 

 Processing of the magnetometer data should be continuous throughout the 

 survey. The assembly of a magnetometer system tailored specifically for use 

 on this project is recommended. Calibration of the magnetometer arrays 

 must include field tests using ordnance with their long axes oriented both 

 parallel and perpendicular to the earth's magnetic field. 



g. Considering the size of the borrow and a line spacing of 8 m, a full-scale 

 operational survey would require a large, non-magnetic research vessel to 

 transit a total of 1,300 nautical miles. Such a survey would take 4-6 weeks of 

 24-hr data collection.
