These multibeam data were collected using SAIC ISS-2000 v 4.0.0.3.0 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. Observed tides were applied during processing. Horizontal accuracy is ~5m (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 ~ 3 - 20 m. The AHI was deployed from shore. The bathymetric data were collected to document the impact of a ship grounding on the benthic habitat and for use as a planning and reference document. Further data were collected to fill gaps in the existing bathymetry.

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 Transducer serial #: 201004 Firmware, dry: 8101-2.09-2E34D Firmware, wet: 8101-1.08-C215 POS/MV Model 320, version 4.0000 (w/ TrueHeave but no RTK) PCS serial #: 2514 IMU serial #: 203 Controller software: v 3.4.0.0 PCS Firmware: 3.41 Seabird SBE19 CTD: Serial #: 3029 Last Callibration: 09/2013 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.
