Pacific Islands Benthic Habitat Mapping Center (PIBHMC), Coral Reef Ecosystem Division (CRED), Pacific Islands Fisheries Science Center (PIFSC), National Marine Fisheries Service (NMFS), National Oceanic and Atmospheric Administration (NOAA) 20070824 Generic Sensor Format (GSF) digital data http://www.soest.hawaii.edu/pibhmc/ EM300 and EM3002D multibeam Data were collected from May 12-22, 2007, aboard NOAA Ship Hi'ialakai at Santa Rosa Reef, Guam Island, Rota Island, Aguijan Island, Tinian Island, and Saipan Island during cruise HI0702. 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. 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 Santa Rosa Reef, Guam Island, Rota Island, Tinian Island, and Saipan Island was done by the R/V AHI in water depths ranging from ~10-350m with the data set being AHI0702; (metadata for AHI0702 are submitted separately.) 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. 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, 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: SIMRAD EM300 multibeam echosounder Serial #: 303 PU Software Versions: PU: 2.0.3 060421 DDS: 3.27 2005/02/17 BSP: 2.3.3 050822 SPRX: 1.1.3 040427 SPTX: 2.0.0 040614 SIS Software Version: 3.2.2, build 54, Sept 7 2006 SIMRAD EM3002D multibeam echosounders Serial #: 357 and 353 PU Software Versions: HCT: 2.0.7 040906 BSP67 Master: 1.3.1 060113 BSP67 Slave: 1.3.1 060113 PU: 1.8.7 060831 DDS: 3.18 2005/11/24 SIS Software Version: 3.2.2, build 54, Sept 7 2006 HI'IALAKAI POS/MV Model 320, version 4.000000 PCS serial #: 2484.000000 IMU serial #: 1333 PCS Firmware: 2.900000 Controller software: v 3.410000 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. During the 2006-2007 winter inport period the main mast was replaced. POS antenas were surveyed in and a patch test was performed in mid April.
