These multibeam data were collected using SAIC ISS-2000 software in the Generic Sensor Format and processed using SABER editing software. Sound velocity corrections from a Seabird SBE19 CTD sensor and motion corrections from a POS-MV vertical reference were applied to the data in real time. Predicted tides were applied to the data in real time and observed tides were applied in postprocessing. Horizontal accuracy is 5m (differential GPS correctors applied), vertical accuracy is depth dependent (~1% of water depth), WGS84 datum. These data are not to be used for navigation. Depths mapped range from 10 - 250 m. The AHI was deployed from the NOAA Ship Hi'ialakai and concurrent mapping was done using Simrad EM300 and EM3002D sonars aboard the ship; metadata for HI-05-04 are submitted separately. Purpose: 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. Supplemental_Information: Data were collected aboard the R/V AHI (Acoustic Habitat Investigator), a 8 m (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 which measures bathymetry and acoustic backscatter imagery, a TSS/Applanix POS/MV Model 320 which measures time, position, velocity, attitude and heading, and a Seabird SBE 19 CTD used to measure sound velocity profiles. The AHI's equipment serial numbers, software versions and sensor configuration settings are as follows: RESON 8101-ER multibeam echosounder Transducer serial #: 201004 Firmware, dry: 8101-2.07-2D4D Firmware, wet: 8101-1.06-2F6B R/V AHI POS/MV Model 320, version 3 PCS serial #: 474 IMU serial #: 203 Controller software: v 2.1 PCS Firmware: 2.16, Sep 15, 2004 Seabird SBE19 CTD: Serial #: 3029 R/V AHI Lever Arm Distances and Alignment Offsets: The R/V AHI Reference Point (RP) is defined to be the intersection of the vessel's centerline, the cabin deck and the bulkhead immediately aft of the transducer. This is marked by a punch in the deck weld at that location. Positive X means the point is forward of the RP, positive Y means the point is to starboard of the RP, positive Z means the point is below the RP. The loaded waterline is defined as the intersection of the vessel's performance wing with the hull at the transom.

Predicted tides were applied to the data in real time and observed tides were applied in post processing. Tide zoning and offset values were provided by the NOAA NOS CO-OPS program and predicted and observed tides for the appropriate tide gauges were downloaded from the NOAA CO-OPS website. Observed tides were applied based upon updated tide zoning information provided by NOAA CO-OPS in 2006. SAIC's ISS2000 and SABER software were used to produce predicted and observed tide files for each tide zone. Multibeam data vertical accuracy is ~1% of water depth.
