Survey operations took place over three legs: Leg 1 (7/25-8/5), Leg 2 (8/25-9/2), and Leg 3 (9/16-9/28). The survey platform was the Research Vessel (R/V) Echo, which was equipped with a Teledyne-Reson SeaBat 7125 multibeam echosounder for simultaneously acquiring bathymetry and acoustic backscatter imagery.

Gaps where no backscatter data was recorded are shown in figure 4 of the processing report. Only a very small fraction of the area has gaps. In July-September 2020, a hydrographic survey was conducted in three survey areas located on the western side of Bayfield Peninsula in southwestern Lake Superior. Survey operations took place over three legs: Leg 1 (7/25-8/5), Leg 2 (8/25-9/2), and Leg 3 (9/16-9/28). The survey platform was the Research Vessel (R/V) Echo, which was equipped with a Teledyne-Reson SeaBat 7125 multibeam echosounder for simultaneously acquiring bathymetry and acoustic backscatter imagery. Backscatter imagery processing was conducted using Quality Positioning Systems (QPS) Fledermaus Geocoder Toolbox (FMGT) software (version 7.9.3). Processed bathymetry data files were exported from CARIS HIPS as Generic Sensor Format (GSF) files. The FMGT workflow paired each native sonar file (Teledyne-Reson s7k format) with its processed GSF file, thus incorporating corrected position and motion data. A beam pattern correction was computed and applied to remove angular bias from the backscatter imagery. Angle Varying Gain (AVG) was applied using the standard “Flat” algorithm and window size of 300 pings. A backscatter imagery mosaic was produced using standard line weighting procedures. The backscatter mosaic was then reviewed manually for motion artifacts and/or brightness offsets. Manual editing was performed to adjust brightness values between adjacent survey lines and/or survey days using the “Head Bias” tool in QPS FMGT software. After the completion of backscatter data processing and quality review, the backscatter imagery was exported in 2m pixel resolution. Backscatter products are referenced to NAD83 UTM Zone 15 North with horizontal units in meters. Backscatter intensity is shown in logarithmic units of decibels (dB). Data were added to the Digital Coast Data Access Viewer. The data files were unchanged in this process. 2021-04-09T00:00:00 NOAA Office for Coastal Management (843) 740-1202 coastal.info@noaa.gov processor Backscatter geotiff files Dave Evans and Associates originator
