Abstract:
EM300 and EM3002D multibeam Data were collected from 2 - 29 May 2008 aboard NOAA Ship Hi'ialakai at Necker Island, French Frigate Shoals, and Brooks Bank in the Northwestern Hawaiian Islands, during cruise hi0804. 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 SBE 9/11 plus CTD 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. Horizontal accuracy is 20 m (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 ~20-3000 m. Concurrent mapping at French Frigate Shoals was done by the R/V AHI in water depths ranging from ~10-350 m with the data set being ahi0804; (metadata for ahi0804 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 Hiialakai, 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, 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 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:

Hiialakai Lever Arm Distances and Alignment Offsets: The Hiialakai'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.

Vertical_Positional_Accuracy_Value: 1
Vertical_Positional_Accuracy_Explanation:
Accuracy varies with water depth. Predicted tides were applied to the data in real time. Tide zoning and offset values were provided by the NOAA NOS CO-OPS program and predicted tides for the appropriate tide gauges were downloaded from the NOAA CO-OPS website. SAIC's ISS2000 and SABER software were used to produce predicted tide files for each tide zone. Multibeam data vertical accuracy is ~1% of water depth.
