All equipment and survey methods were used as detailed in the DAPR. Backscatter was collected but not processed.No junctions provided for survey F00746.It has been well documented that the NRT vessels have significant bubble noise created by the hull. This issue was especially prevalent in this survey due to the direction of wave action coming mainly East to West while survey lines were run North to South. Due to the natural slope of the seafloor rising from East to West the line plans could not be effectively changed because of the SSS range scale.Known bubble sweep down hull issue.0ERS via VDATUM0.09425520.5S300900Tide uncertainty values derived from project instructions. Sound speed uncertainty values derived from manufacturers recommendations.Set line spacing MBES with concurrent 200% was used to realize object detection coverage for the entire survey. In the deepest areas 100% MBES was achieved.MBES crosslines for survey F00746 totaled 19.2% of the mainscheme MBES. Comparison of the mainscheme vs. crossline CUBE surfaces yielded good results with a Standard Deviation of 10 cm and mean difference of 0.0 cm from 585,000 soundings.SupportFiles\Difference stats.PNGF00647 MBES crossline comparison.Casts were taken as close to every 2 hours as possible.A total of 17 SVP casts were taken over 3 days during F00746.Sonar system quality control checks were conducted as detailed in the quality control section of the DAPR.It has been well documented that the NRT vessels are incapable of handling even the most seemingly benign sea states. Acquisition for F00746 took place in what any reasonable person would call calm seas of 2 feet or less with long period. Due to the instability of the survey vessel and bubbles created by the roll, data quality was severely impacted and required extensive cleaning during post-processing.Vessel stability in seas.NOAA Profile Version 2019Variable ResolutionNOAA_VRF00746_MB_VR_MLLW_Final55.85.5CARIS VR Surface (CUBE)Object Detection1N/AF00746_SSAB_1m_400kHz_1of200SSS Mosaic100% SSS1N/AF00746_SSAB_1m_400kHz_2of200SSS Mosaic200% SSSMBESEM 2040CKongsberg MaritimeSSS4125EdgeTechPositioning and Attitude SystemPOS MV 320 v5ApplanixSound Speed SystemMicroX SVAML OceanographicConductivity, Temperature, and Depth SensorCastAway-CTDYSISupportFiles\S3009.jpgS3009S3009 is a 32 foot hydrographic survey vessel used for inshore and nearshore surveys.100.75S3009Refer to the Data Acquisition and Processing Report (DAPR) for a complete description of data acquisition and processing systems, survey vessels, quality control procedures and data processing methods.

This area is utilized by multi-agency and commercial contractors for calibration and validation of bathymetric lidar sensors. The new data will help assist with these efforts. Survey data from this project is intended to supersede all prior survey data in the common area. Data from this survey is requested by RSD to be left at ellipsoid height rather than MLLW. A .csar surface in this datum is included in the Constituent Products folder for branch review before submission to RSD. Once approved NRT2 will submit the requested files to RSD.

I have reviewed the attached survey data and reports.The survey data meets or exceeds requirements as set forth in the NOS Hydrographic Surveys Specifications and Deliverables, Field Procedures Manual, Letter Instructions, and all HSD Technical Directives. These data are adequate to supersede charted data in their common areas. This survey is complete and no additional work is required with the exception of deficiencies noted in the Descriptive Report.
