Abstract:
EM300 and EM3002D multibeam data were collected from 23 June to 20 July 2006 aboard NOAA Ship Hi'ialakai at Kure Atoll, Pearl and Hermes Atoll, Midway Island, and Kaua'i Island in the Central Pacific during cruise HI-06-09. These multibeam data were collected using SAIC ISS-2000 software in the Generic Sensor Format and processed using SABER editing software. Surface sound velocity values were supplied by a Seabird SBE-45 MicroTSG and a SBE-38 remote temperature probe. Sound velocity corrections from a Seabird 911 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 using tide zoning and predicted tides supplied by NOAA's National Ocean Service Center for Operational Oceanographic Products and Services (CO-OPS). At Kure Atoll, Sand Island (1619910) predicted tides were used in zone HI48. At Pearl and Hermes Atoll, Sand Island (1619910) predicted tides were used for zones HI46 and HI47. At Midway island, Sand Island (1619910) predicted tides were used for tide zone HI47. At Kauai Island, Nawiliwili (1611400) predicted tides were used for tide zones HI137, HI139, HI152, HI153, HI154, and HI155.

Horizontal accuracy is 20m (no 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 2 to 3050 m. Concurrent mapping was done by the R/V AHI in water depths ranging from ~2-300 m with the data set being AHI-06-09; metadata for AHI-06-09 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 unmappedareas; 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 68 m (218') NOAA Ship Hi'ialakai. The Hi'ialakai's survey sensors include a 30 kHz Simrad EM300 sonar and a 300 kHz Simrad EM3002d sonar, both of which measure bathymetry and acoustic backscatter, a TSS/Applanix POS/MV Model 320, which measures time, position, velocity, attitude and heading, and a Seabird SBE 9/11 plus CTD used to measure sound velocity profiles.

The Hi'ialakai's equipment serial numbers, software versions and sensor configuration settings are as follows:

Hi'ialakai Lever Arm Distances and Alignment Offsets: The Hi'ialakai's Reference Point (RP) is a granite block situated 1.222 m starboard of the ship's centerline, 1.23 m above the ship's baseline/datum on the keel. The RP is located under the forward deck, in the ship's laundry room. The ship's sensors, the sonar systems and permanent benchmarks are measured with respect to the RP. 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 survey waterline is defined to be at the 15' draft mark on the vessel's starboard side.
