Project 9.
NOAA Ordnance Reef Survey,
Five Miles off Pokai Bay, Waianae, Hawaii

Project Owner: NOAA -National Oceanic and Atmospheric Administration
Prime: Yes
Subcontract: No

In June 2006, as part of a DoD/NOAA effort to characterize a known munitions disposal area, NOAA contracted OIC to provide data acquisition and processing services for a reef in waters approximately 10 to 70 meters (40 to 225 feet) deep.

The survey team consisted of members from NOAA’s National Marine Sanctuary Program, National Marine Fisheries Service, Teledyne-Benthos, and OIC. OIC’s GeoDAS software and a C3D sonar were used to map an area of four square kilometers in water depths from five meters to 50 meters. Thee survey was completed in two 10-hour days; OIC produced a 50 cm resolution bathymetric map and a  10 cm resolution sidescan mosaic.

The survey was extended to deeper waters, using the new dual-frequency Teledyne Benthos SIS 1624 sidescan, adding another four square kilometers, and covered targets in waters from 50 to 100 meters depth.

The survey verified the presence of munitions ranging from small arms projectiles to large-caliber artillery projectiles, and naval gun ammunition. About 100 previously undiscovered munitions were found in nine clusters near shore.
