Geospatial_Data_Presentation_Form: Generic Sensor Format (GSF) digital data Online_Linkage: http://soest.hawaii.edu/pibhmc Description: Abstract: Reson 8101ER multibeam Data were collected between 22-26 September 2003 (JD 265-269) aboard NOAA Survey Launch Acoustic Habitat Investigator (AHI) at Guam Island in the Territory of Guam in the Western Pacific during cruise OES-03-07/AHI-03-07. The AHI was deployed independently from the NOAA Ship Oscar Elton Sette (OES) during the cruise. The multibeam data were logged into data set Guam and collected using SAIC ISS-2000 software in 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 and observed tides from Guam tide gauge 1630000 were applied using SABER postprocessing software. 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 ~10 - 300 m. 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 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. The AHI's equipment serial numbers, software versions and sensor configuration settings are as follows: RESON 8101-ER multibeam echosounder DOC inventory #: CD0000537418 Transducer serial #: 201004 Firmware, dry: 8101-2.07-2D4D Firmware, wet: 8101-1.06-2F6B R/V AHI POS/MV Model 320, version 3 DOC inventory #: CD0000476647 PCS serial #: 474 IMU serial #: 203 Controller software: v 1.0.5.0 PCS Firmware: 2.16 Seabird SBE19 CTD: Serial #: 3029 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.
