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/ Reson 8101ER multibeam Data were collected between 23 May - 9 June 2007 aboard NOAA Survey Launch Acoustic Habitat Investigator (AHI) at Maug Islands, Pagan Island, Saipan Island, Tinian Island, Aguijan Island, Anatahan Island, Sarigan Island, Zealandia Bank, Guguan Island, Alamagan Island, Agrihan Island, Asuncion Island, Supply Reef, and Uracus Island, Western Pacific during cruise AHI0703. These multibeam data were collected using SAIC ISS-2000 softwarein 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 using predicted tides downloaded from NOAA's National Ocean Service Center for Operational Oceanographic Products and Services (CO-OPS) website. Horizontal accuracy is ~5m, DGPS from NavCom sensor from C&C Technologies was used, vertical accuracy is depth dependent (~1% of water depth), WGS84 datum. These data are not to be used for navigation. Depths mapped range from 5 - 350 m. The AHI was deployed from the NOAA Ship Hi'ialakai and concurrent mapping was done using the Simrad EM300 sonar aboard the ship; metadata for HI0703 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 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. 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. A C&C Technologies NavCom sensor and the C-NAV RTG network, which is a global system for the distribution of differential GPS corrections, was used for navigation. 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 4.0000 PCS serial #: 2514 IMU serial #: 203 Controller software: v 3.4.0.0 PCS Firmware: 3.41 Seabird SBE19 CTD: Serial #: 3029 Calibrated 12/28/2006 C&C Technologies NavCom Serial #5111 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. A vessel offset survey and patch test were performed in March 2007 and the settings shown here reflect these data.
