PART A - SECTION 2 - GEOPHYSICAL ERW SURVEY
1.0 SURVEY OBJECTIVES
To systematically acquire accurately positioned digital magnetic data over accessible areas of the site from
which the existence of each discrete ferrous object equal to or greater in magnetic signature to an Aircraft
20lb Frag Bomb or larger, would be located with high confidence to a depth beyond that likely through
normal kinetic penetration.
1. All data captured during the investigation would be interpreted by a Geophysicist experienced in
discrete UXO item interpretation utilising special purpose compiled software. Positioning of all
discrete ferrous anomalies during the investigation phase would be achieved with an integrated High
Precision Global Positioning System (HPGPS) accurate to 10 centimetres.
2. Acquired data is then presented as colour images showing the position of each anomaly in plan form.
Complementing the colour images are Investigation and Relocation lists also known as a Dig-“heet , listing the position of each anomaly detected.
2.0 PRE-INVESTIGATION ASSESSMENT
As a result of the pre-investigation assessment, it was considered that naturally occurring magnetic
background noise levels would not preclude the use of the magnetic method over the majority of the Site
though there clearly would be issues with any sort of metal detection system due to the large amount of
metal on the site. Accordingly, the Geometrics G858 magnetometer was selected as an appropriate
technology to locate those ferrous items matching the target specifications.
The G858 Magnetometer is a dual sensor caesium vapour total field magnetometer designed to measure
and record the magnetic field strength of the earth to a high level of accuracy. Ferrous metal objects
cause the earth’s ag etic field to cha ge directio a d a plitude. These ag etic pertur atio s are located by sensitive magnetometer sensors and the variations in field strength are used to model the
position, depth and theoretical mass of the buried ferrous item. Technical specifications for the G858 are
presented at Enclosure 2.
3.0 POSITIONING
The HPGPS system was integrated with the G858 magnetometer to provide accurate location of all
magnetometer traverses. Sensors on the dual system were spaced 100 centimetres apart and the system
was walked along lines paralleling the site boundaries (approximately 105 degrees and 15 degrees
bearing).
Milsearch Project Reference: NAU 53916
4.0 G858 MAGNETOMETER
4.1 Instrument Calibration and Testing
Prior to the commencement of the data acquisition phase the G858 magnetometer was
calibrated to ensure it functioned within the Original Equipment Manufacturer (OEM)
specifications.
When testing it is preferable to use a locally derived target to confirm that the magnetometer
system is working properly and to calibrate interpretation since the target response can be
dependent on local conditions and also on the deterioration of metal objects in the
environment.
A 20lb fragmentation bomb found in the area was chosen for the test. It proved impossible to
locate a clear, non-contaminated area on land and the target was therefore placed on the reef
in natural hollow.
Plate 1: 20lb Fragmentation Bomb Test Target in Place
A 5 x 10 metre area was surveyed over the target as shown in the following figure. Calculations
of the terminal velocity of a 20lb frag bomb suggest that the maximum speed this should
impact is approximately 160 m/s. This would result in a theoretical maximum penetration into
coral of around 10cm though in loose dune sand this penetration could be as much as a metre.
To provide a high level of confidence for interpretation within the reef area the target was
surveyed to simulate a burial depth of 30cm.
Milsearch Project Reference: NAU 53916
There is a clear response over the test target over some 40nT below background. A value of
½ this, namely 20nT is therefore selected for interpretation to again provide a confidence
buffer. Note that the target was actually located between two lines in order to give a
minimum response.
The large low to the west is a magnetic object that was not visible on the surface.
Figure 1: Data Captured Over Test Target
4.2 Data Acquisition
Where possible a 100% systematic magnetic survey utilizing the Geometrics G858
Magnetometer was conducted over the period 2nd August to 5 August 2016.
Page 8 of 24
Milsearch Project Reference: NAU 53916
During data acquisition the detector sensors were carried at an elevation as close to the
ground as was practical. This was usually around 20-30 centimetres above ground. This is
considered appropriate for locating 20lb frag bombs and larger items.
Integrity of the transect lanes was achieved by laying out measuring tapes at the start and
finish of each grid line placing string lines along the ground between these for the equipment
operator to follow.
Data was recorded at 0.1 second increments along each line which resulted in an
approximate data spacing of 10-12 centimetres. An audio monitor of the mixed, multi-
channel responses provides feedback to the operator on the functionality of the sensor and
the presence of targets. During data acquisition, the magnetic response is also displayed on
a screen.
Plate 2: Magnetic Survey on the Reef Area
As can be seen on the following plot there were occasional locations where the operator had
to deviate around obstacles, however, where clear lines are available, the lines in general are
straight.

Each profile GPS plot was reviewed by the geophysicist for unacceptable occurrences of bad
divergence from the intended line or areas where the GPS status indicator showed that High
Precision GPS (HPGPS) had not been recorded. Coloured plots of GPS status were provided
to the field operators indicating where the GPS has recorded Differential GPS (DGPS) instead
of HPGPS. The red lines in Figure 2 below show an area which was resurveyed because of
unacceptable line spacing. In the more cluttered areas it was impossible to get a reliable GPS
signal and the lines were therefore accepted as they are.
Figure 2: Line Location Plot
Milsearch Project Reference: NAU 53916
It proved impossible to survey much of the southern and central parts of the area due to the
presence of buildings, shipping containers, vehicles and other large ferrous metal objects.
To the west part of the defined area was in deep water or too close to the edge of the reef to
survey safely.
4.3 G858 Data Processing
The multi-channel data files in a proprietary survey-line format were downloaded to a
personal computer from the G858 magnetometer at the e d of the ea h day’s data acquisition. Data transfer involved the use of the MagMap2000 data transfer and editing
program. This program also permits checking of the quality of the location information and
application of corrections for the offset between the HPGPS antenna and the magnetic
sensors. The data with positional coordinates is exported from MagMap2000 in an ASCII
format multi-channel file.
4.4 Data Reduction and Pre-Processing
The earth’s ag eti field has a significant diurnal variation that needs to be removed before
the data can be examined and before a composite picture can be produced. Broad geological
or cultural anomalies also may need filtering out. Both of these aims can be achieved using a
wide median filter, in this case a 101 point filter. This is applied to the data in the ASCII text
file using proprietary software.
4.5 Data Organisation and Gridding
This pro ess i ol ed utilised Golde “oft are’s “urfer pa kage, to apply Krigi g interpolation to the XYZ data files to generate regularly spaced grid files having a uniform cell
size of typically 20 centimetres.
The Surfer software is also used to generate plots of the data.
4.6 Data Interpretation
The data was processed as a whole a d a Dig-“heet produ ed do u e ti g the positio of each metallic object identified. The data was scanned for anomalies exceeding a predefined
amplitude threshold, in this case 20nT. The appropriate threshold value was determined by
analysing the results of the survey of the test block as mentioned previously.
All the data captured was assessed for suitability and accuracy. Sections of the data in the
east and southeast were not considered adequate for UXO detection because of interference
from buildings and metal rubbish. The data over the beach was also highly affected by
magnetic scrap and rubbish so that individual items of a response like that of a 20lb frag
bomb could not be identified with confidence.

5.0 MAGNETIC SURVEY LIMITATIONS (Magnetically Hostile Areas)
At the conclusion of the G858 magnetometer investigation phase, all the captured data was assessed for
suitability and accuracy. Several areas were found to have much higher than acceptable magnetic levels
due to rubbish, shipping containers, buildings, and scrap metal. This meant that in those portions of the
site, confident discrimination of the 20lb fragmentation bomb anomaly was not possible.

The following magnetic image shows the coverage over the Bing photo. Red areas are generally over
100nT in magnetic response and blue below -100nT. Remembering that the target is potentially
anything over 20nT we can see that large areas are so contaminated with metal that recognising a 20nT
response would be impossible.
Figure 4: Processed Magnetic Data Coverage over Bing Photo
The reef area which is mostly coloured green is typical of a normal non-magnetic area with occasional
magnetic targets present. The southern linear anomaly in the reef zone is due to an anchor chain while
the larger linear reef anomaly is a band of reinforced concrete covering a pipe.

Milsearch Project Reference: NAU 53916
There are other types of metal detection technology available with electromagnetics (EM) being
commonly used in areas where the magnetic method is inappropriate but the contaminated portions of
this site are considered so covered in metal that EM in not appropriate either.
6.0 DATA ACQUISITION SUMMARY
3.25 hectares of the 7.9 hectare site was surveyed. Of this approximately 2.5 hectares of the reef is
considered suitable for magnetic surveying and target recognition and 2 hectares is either on the edge
of the reef in the wave zone or in deep water. The remaining 3.4 hectares is either under buildings,
containers or simply too contaminated with metal for any ordnance to be detectable.
A total of 140 anomalies were interpreted in the reef area. Of these 81 are interpreted as at less than
50cm depth and, given the inaccuracy of magnetic depth estimates are probably close to the surface
and easily investigated. The remainder will include quite a few targets that will be buried under the coral
and challenging to recover.
