The pilot study was conducted during 8-15 September 1995, and included the 

 following sequence of activities: 



a. Mobilized equipment and personnel to study site (8-9 September). 



b. Assembled magnetometer and conducted deployment tests (10 September). 



c. Constructed equipment calibration range using inert ordnance in shallow 

 water (10 September). 



d. Conducted tests of magnetometer over the calibration range and deepwater 

 deployment tests (11 September). 



e. Assembled subbottom and conducted tests over calibration range 

 (11 September). 



/. Conducted side-scan sonar survey of northwest corner of borrow area 1 A 

 from NAN vessel (12 September). 



g. Conducted magnetometer survey along long lines adjacent to borrow area 

 1A (12 September). 



h. Conducted dense magnetometer survey of northwest corner of borrow area 

 1A (13 September). 



/. Conducted video camera drift surveys along long lines adjacent to borrow 

 area 1A from NAN vessel (13 September). 



j. Conducted subbottom (X-star) surveys of northwest corner of borrow area 

 1A and long lines adjacent to 1A (14 September). 



k. Obtained video footage of northwest corner of borrow area 1 A using 

 towed video and Remotely Operated Vehicle (ROV) (14 September). 



/. Briefed NAN staff during onsite visit (14 September). 



m. Removed equipment calibration range (14 September). 



n. Conducted magnetometer and side-scan sonar surveys in northwest corner 

 of 1A and long lines adjacent to 1A (15 September). 



o. Coordinated background information with EOD detachments at 

 Fort Monmouth and Earle NAS and determined position of historical 

 batteries (15 September). 



p. Packed equipment and demobilized from site (15 September). 



After completion of the pilot study, the survey tracklines were captured and 

 entered into a GIS database, and the individual data sets were processed. The 

 surveys were conducted in water depths of 30-50 ft (Figure 3). The survey
