NOAA The survey area is referred to as H13348, "2 NM Southeast of Cape Canaveral" (sheet 1) in the Project Instructions. The survey area is approximately 35 square nautical miles (see image below). 28.42600186111111 80.5952015 28.287085222222224 80.35634486111111 H13348 sheet limits shown in blue (Chart US4FL80M and US4FL87M). file:///M:/OPRH321FH21/Surveys/H13348/01_HDR/Reports/Descriptive_Report/Components/images/H13348_sheet_limit.png Complete multibeam echosounder (MBES) coverage was not acquired to the full extent of the assigned sheet limits (see image below). The eastern-most portion of the sheet was too shallow to safely survey with the ship. While it was possible to use the survey launch to cover this area, with the consultation of HSD Operations, it was decided resources would be better spent elsewhere (see Supplemental Correspondence, "Acquisition decisions for OPR-H321-FH-21". These lines were not processed into finalized Variable Resolution (VR) surfaces for submission; however, they are included in the Caris .hips file submitted with this report. H13348 Assigned survey area (black) and acquired survey coverage (green lines). Area denoted by red circle have not been included in submitted grids. file:///M:/OPRH321FH21/Surveys/H13348/01_HDR/Reports/Descriptive_Report/Components/images/H13348_launch_coverage.png Concur with clarification. During office review the lines that were nor processed by the field unit, now are included in a new VR surface that was created during review. This project is located approximately 2 nautical miles southeast of Cape Canaveral. In 2011, Port Canaveral was ranked as the United States' third busiest cruise port by port of departure, reporting 485 cruises and a maximum passenger number of 1,496 per cruise. At the end of September 2019, port officials reported that cruise revenue alone made up $81.9 million of the total $110 million in revenue for Port Canaveral. The port also generated almost 8 billion dollars for the state of Florida, and created over 32.000 jobs in 2019. The types of marine vessels visiting Port Canaveral include: passenger vessels, cargo ships, tug boats, pleasure crafts, tankers, sailing vessels, fishing vessels, and special crafts. In 2019, Port Canaveral dealt with a total of 4,826,738 tons of transported materials. Much of this 430 SNM survey area has not been surveyed since 1930, which was 24 years before the Port was dedicated. Conducting a modern bathymetric survey in the area will provide critical data for the updating of National Ocean Service (NOS) nautical charting products and services to increase maritime safety near Cape Canaveral. Survey data from this project is intended to supersede all prior survey data in the common area. The entire survey is adequate to supersede previous data. Pydro QC Tools was used to analyze H13348 multibeam echosounder (MBES) data density. The submitted H13348 variable-resolution (VR) surface met HSSD density requirements as shown in the histogram below.

Object Detection Coverage The entirety of H13348 was acquired with object detection coverage, meeting the requirements listed above and in the HSSD. Pydro QC Tool Holiday Finder was used to detect gaps on the finalized VR surfaces for submission and found 528 holidays (see image below). Holidays highlighted in red were examined in Caris subset editor, and no there was no evidence of shoaling. Holidays highlighted in blue are outside of the assigned sheet limits. Holidays highlighted in black are further discussed in Section B.2.9 - "Data gaps in Starboard side 2040" of this report.

NOAA Ship Ferdinand Hassler (S250) acquired 35 nautical miles of multibeam crosslines. H13348 crossline data is adequate for verifying and evaluating the internal consistency of survey data. The Compare Grids function in Pydro Explorer analyzed finalized VR surfaces of H13348 crossline only data and mainscheme-only data. In the difference surface, 99.5% of nodes met IHO allowable Total Vertical Uncertainty (TVU) standards. See Figures below for additional detail.

Tidal uncertainty was provided in the metadata accompanying the NOAA vertical datum transformation model used for this survey. The uncertainty value of NOAA's Ellipsoidally Referenced Tidal Datum Model (ERTDM) transformation model was documented in metadata that accompanied the VDatum model. In addition to the usual a priori estimates of uncertainty, some real-time and post-processed uncertainty sources were also incorporated into the depth estimates of this survey. Real-time uncertainties from Kongsberg MBES sonars were recorded and applied in post-processing. Applanix TrueHeave (POS) files, which record estimates of heave uncertainty, were applied during post-processing. Finally, the postprocessed uncertainties associated with vessel roll, pitch, yaw and position were applied in Caris HIPS using SBET and RMS files generated using POSPac MMS software. Uncertainty values of the submitted finalized grid was calculated in Caris using "Greater of the Two" of uncertainty and standard deviation (scaled to 95%). Grid QA v5 within Pydro QC Tools was used to analyze H13348 TVU compliance, a Histogram plot of the results is shown below.

Hassler. Comparisons were made using the Compare Grids program within Pydro Explorer. H13349 10000 2021 Ferdinand R. Hassler S The junction with survey H13349 encompassed approximately 0.37 square nautical miles along the southern boundary of H13348. Pydro's Compare Grids results showed that 100% of nodes in the common area met NOAA allowable error standards. Analysis of the difference surface indicated that H13348 is an average of 0.01 meters deeper than H13349 with a standard deviation of 0.06 meters. See figures below for more information.

NOAA Ship Ferdinand R. Hassler Launch 2702 vertical offset Inspection of survey H3348 MBES data revealed a static vertical offset between data acquired by NOAA Ship Ferdinand R. Hassler and that of her launch 2702, wherein launch data is approximately 15 cm lower. The origin of the offset is suspected to originated from R2Sonic sonar integration errors on launch 2702, though the exact cause could not be determined. 2702 lines were processed into the final VR surface, as but only for holidays. Although the surface created by the launch data is offset deeper than the the surface created by S250, there is no indication of shoaling or obstructions in the launch data. The depths may not be accurate, but based off the data we can say with a high degree of certainty that there are no dangers in this area. While the data offset is not ideal it falls within total allowable TVU for processed depths and was therefore kept in the finalized Variable Resolution (VR) surfaces for submission. Consultation with Hydrographic Survey Division (HSD) and Hydrographic Systems and Technologies Branch (HSTB) can be found in Project Correspondence section attached to this report.

Hassler, as well as when significant changes in surface sound speed were observed. Sound speed profiles were obtained using Sea-Bird 19plus SEACAT Profilers for launch-acquired data, and ODIM Brooke Ocean MVP 200 for ship-acquired data. All casts were concatenated into a master file and applied to MBES data using the "Nearest distance within time" (4 hours) profile selection method.

Data gaps in Starboard side 2040 Inspection of MBES acquisition data acquired by NOAA Ship Ferdinand R. Hassler on DN160 and DN161 revealed excessive data gaps in the starboard side (STBD) Kongsberg 2040. These data gaps were caused by incorrect sonar setting during acquisition, specifically the ping rate hertz limit and "dual swath" mode not being activated. These data gaps contribute to the number of holidays in the finalized VR surface used for submission. Due to time constraints reacquiring data with the appropriate settings was not possible.

All sounding systems were calibrated as detailed in the DAPR. All equipment and survey methods were used as detailed in the DAPR. Raw MBES backscatter was flagged as part of the .all file from the Kongsberg EM2040 systems. Backscatter was processed in QPS Fledermaus GeoCoder Toolbox (FMGT) software, and the exported geotiffs are include in the final processed data submission package. A portion of S-250 lines from DN 193 exibited slight offset making them apear darker in color that the rest of the mosaic. Additionally line S-250_193_0202_20210712_000702_S250 was excluded from the mosaic due to an error with the pos data.

Limited charted feature verification was conducted in accordance with applicable sections of NOAA HSSD and FPM using the Project Reference File (PRF) and Composite Source File (CSF) provided with the Project Instructions. In the field, all assigned features that were safe to approach, were addressed as required with S-57 attribution and recorded in the H13348 Final Feature File to best represent the features at chart scale. This file also includes new features found in the field as well as recommendations to update, retain, or delete assigned features. Features were run through the Valsou Check functions of Pydro QC tools which flagged 4 features as not matching the processed depth of the surface. These were all charted features with updated least depths. All feature where examined and the difference between the surface nodes and the features were on average a distance of 0.006 m which is less than the maximum precision specified in the HSSD (ie 0.0000001 degrees for x/y) No uncharted features exist for this survey. Channels, designated anchorages, precautionary areas, safety fairways, traffic separation schemes, pilot boarding areas, and/or channel and range lines exist within the survey limits, but were not investigated. Eleven navigational aid buoys and one scientific wave buoy were assigned in the the project instructions. No Maritime Boundary Points were assigned for investigation in this survey. Seven bottom samples were assigned for this survey and successfully acquired. The results are included in the H13348 Final Feature File submitted with this report. No overhead features exist for this survey. No submarine features exist for this survey. No platforms exist for this survey. No ferry routes or terminals exist for this survey. No abnormal seafloor or environmental conditions exist for this survey. No present or planned construction or dredging exist within the survey limits. No new surveys or further investigations are recommended for this area. No new ENC scales are recommended for this area. As Chief of Party, field operations for this hydrographic survey were conducted under my direct supervision, with frequent personal checks of progress and adequacy. I have reviewed the attached survey data and reports. All field sheets, this Descriptive Report, and all accompanying records and data are approved. All records are forwarded for final review and processing to the Processing Branch. 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.
