The GeoTIFF and Arc ASCII file includes data that were collected using a Klein 3000 high-resolution side-scan sonar system with dual operating frequencies of 100 and 500 kHz. The data were collected in 2008 by the NOAA Office of Coast Survey and the United States Navy Fleet Survey Team and were preliminarily processed by NOAA OCS using the Caris software. Additional processing and mosaicking was performed by the NOAA Coral Reef Ecosystem Division. The GeoTIFF and Arc ASCII of side-scan imagery were created using data gathered from multibeam soundings for use as a planning and reference document. The data are also being used for benthic habitat mapping, for locating Essential Fish Habitat, and for studying geologic features of the area. Refer to the supplemental information for instrument and survey information.

The Klein 3000 Side Scan Sonar is operated in the stern-towed configuration. Additional detailed information on data acquisition, equipment configuration, and corrections can be found in the Data Acquisition and Processing Report (DAPR) that can be accessed at: www.soest.hawaii.edu/pibhmc and is included in the ZIP file containing the side-scan GeoTIFF. Entity and Attribute Overview: Backscatter data within a GSF file are arranged as small sequences of intensity values, one sequence per beam per ping. The intensity values represent the amplitude of echo returns to the sensor and can be related to seabed hardness and roughness.

The along-track resolution is approximately 30cm at the 100m range scale, even when acquiring data at speeds up to 10 knots. Across-track resolution is typically 7.5cm at the 100m range scale. The achievable 0.3m resolution meets the OCS Hydrographic Surveys Specifications and Deliverables Manual for object detection. ISIS Sonar Pro is used to acquire data with the Klein 3000 SSS. Sonar Pro is a Windows-based acquisition software package that provides real-time data display and sonar control. Sonar Pro is used to acquire Klein 3000 data in XTF format. Data acquisition is monitored real time by a qualified sonar operator. The primary user settings that are adjustable during SSS acquisition are the range scale and the resolution. Typically, the range scale and resolution are set prior to logging data and not changed again until the surveyed depth area changes. Caris HIPS/SIPS (Hydrographic Information Processing System/ Side-scan Information Processing System) is used for processing, correcting, and analyzing all bathymetric, side scan, and phase-differencing bathymetric sonar data. Caris SIPS is used for converting and correcting side-scan sonar imagery and for contact selection and mosaic generation. After acquisition, SSS data are converted from XTF format to Caris HDCS format. Fish height, vessel heading (gyro), and vessel navigation records are then reviewed and corrected and recalculated. Data are then slant-range corrected to 0.1m with beam pattern correction. Side scan mosaics were created using the SIPS side scan editor. Mosaics consisted of combinations of lines that resulted in a seamless product after interpolation was applied during GeoBAR creation in Caris SIPS. Since the dataset is so large, a final mosaic was created using ArcGIS 9.x Raster Dataset Tools in the Toolbox.
