Data were also collected aboard the R/V AHI (Acoustic Habitat Investigator), a 25' survey launch owned and operated by the NOAA Pacific Islands Fisheries Science Center in Honolulu, HI. The R/V AHI's survey sensors include a 240 kHz RESON 8101-ER sonar providing bathymetry and imagery data, a TSS/Applanix POS/MV Model 320 which measures position, velocity, attitude and heading, and a Seabird SBE 19 CTD used to measure sound velocity profiles. Sensor configuration for the AHI for cruise AHI-06-02 is documented in the cruise/multibeam metadata file AHI0602_MB_Metadata.txt. Sensor configuration for the AHI for cruise AHI-04-02 is documented in the cruise/multibeam metadata file AHI0402_MB_Metadata.txt. Additional data for the Faga'itua bay area were gathered by the Kongsberg Simrad EM-3000 system, contracted from the Center for Coastal Ocean Mapping of the University of South Florida (USF), and operated from a boat owned by the Department of Marine & Wildlife Resources (DMWR) of the America Samoa Government.

The data were collected in support of Coral Reef Conservation Program goals to map all shallow (0-30 m) coral reefs in US Pacific waters and priority moderate (> 30 m) depth areas by 2009. The data are being used to provide bathymetric and backscatter data for previously unmapped areas; in support of ecosystem management requirements for benthic habitat mapping and location of Essential Fish Habitat; and to study the geologic features of the area.
