Abstract:
EM300 multibeam data were collected in 15 March to 8 April 2006 aboard NOAA Ship Hi'ialakai at Jarvis Island, Palmyra Island, and Kingman Island in the Central Pacific during cruise HI-06-04. 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. At Jarvis Island, Hilo (1617760) predicted tides were used with a +2.0 time corrector and a range ratio of 1.10. At Palmyra and Kingman, Honolulu (1612340) predicted tides were used with a +1 hr 19 min time corrector and a range ratio of 0.56.

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 20 to 3500 m. Concurrent mapping was done by the R/V AHI in water depths ranging from 10-250 m with the data set being AHI-06-04; metadata for AHI-06-04 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 NOAA Ship Hi'ialakai, a 68 m (218') United States National Oceanographic and Atmospheric Agency (NOAA) research ship. The NOAA Ship Hiialakai's survey sensors include a 30 kHz Simrad EM300 sonar and a 300 kHz Simrad EM3002d sonar (not used on HI-06-04), both of which measure bathymetry and acoustic backscatter imagery, 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:

SIMRAD EM300 multibeam echosounder Serial #: 303 PU Software Versions: 1.1.3 040427,2.0.0 040614,2.3.2 040615,2.0.1 040629 SIS Software Version: 1.0, build 117, July 2, 2004

HI'IALAKAI POS/MV Model 320, version 3 PCS serial #: 295 IMU serial #: 1333 PCS Firmware: 2.21, Feb 02, 2006 Controller software: v 2.1

Seabird SBE 9/11 plus CTD: Serial #: 09P35130-0737

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.
