NOAA Survey H13478, located within the Approaches to New York, sub locality of East of Barnegat Inlet, was conducted in accordance with coverage requirements set forth in the Project Instructions OPR-C319- FH-21. 39.87778333333333 73.95975833333334 39.72410555555556 73.78359166666667 H13478 assigned survey area (Chart 12323). SupportFiles\H13478_Sheet_Limits.PNG The entire extent of the assigned H13478 sheet limits were not surveyed due to time constraints - see Section A.4 for further details. The Port of New York and New Jersey, is the largest importer of goods in the United States by volume, handling over 74,000,000 short tons in 2018. With larger Post-Panamax ships with deeper drafts often calling upon the Port of New York and New Jersey, accurate navigational charts are essential for the continued safe transit of vessels in and out of the Port. This 930 square nautical mile survey area offshore of the coast of New Jersey encompasses two traffic separation schemes for large vessels calling upon the Port of New York and New Jersey, and will supersede 1970 vintage chart data for the area. This project will provide modern bathymetric data to update National Ocean Service (NOS) nautical charting products as well as support the Seabed 2030 global mapping initiative in this heavily trafficked area, which supports commerce along the eastern seaboard. The entire survey is adequate to supersede previous data. All waters in survey area Complete Coverage (Refer to HSSD Section 5.2.2.3) The south west corner of the assigned limits of H13478 was not surveyed due to operational time constriants. The limited coverage in this area resulted in three coverage gaps (holidays) present in the submitted bathymetric surfaces. There is one additional holiday present in the south east region of the survey area created by insufficient overlap of neighboring MBES swaths. See figures below for details.

SupportFiles\NOAA Ship FERDINAND HASSLER.jpeg All data for survey H13478 was collected by NOAA Ship Ferdinand R. Hassler. The vessel acquired MBES bathymetry, backscatter and sound velocity profiles.

Hassler collected 66.46 linear nautical miles (5.9%) of MBES crosslines, across a range of depths in the mainscheme data. The Compare Grids function in Pydro Explorer was used to analyze the finalized variable resolution (VR) surfaces of H13478 mainscheme only and crossline only data. Pydro determined that over 99.5% of nodes met allowable uncertainties. For additional results, see plots below. H13478 crossline surface overlaid on mainscheme tracklines.

Tidal uncertainty was provided in the project instructions for the NOAA vertical datum transformation model used for this survey. In addition to the usual a priori estimates of uncertainty, real-time and post-processed uncertainty sources were also incorporated into the depth estimates of this survey. Real-time uncertainties for position, navigation, attitude, and vessel motion data from Applanix POS MV were applied during acquisition and initially in post-processing. POSPac SBET and RMS files were later applied in CARIS HIPS to supersede POS MV uncertainties associated with GPS height and position. Uncertainty values of the submitted finalized grids were 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 H13478 TVU compliance. H13478 met HSSD requirements in over 99.5 percent of grid nodes, which is shown in the histogram plot below.

The mean difference between bathymetric surface nodes was 0.01m with a standard deviation of 0.09m. Statistical analysis and visual inspection indicate that the surveys are in general agreement.

None Exist There were no conditions or deficiencies that affected equipment operational effectiveness. Sound Speed During the review of the data it was observed that there is a sound speed offset affecting some of the lines in survey H13478. The offset was determined to be the result of stratification. Data quality was not affected by this offset. Example of sound speed issues identified in MBES data. SupportFiles\SS_Offset.PNG At least one cast every four hours or as needed. Eighty seven sound speed profiles were acquired for this survey in various locations at least once every four hours or as needed. S250 sound speed profiles were acquired using ODIM Brooke Ocean MVP200. Casts were also acquired using a Sea-Bird Scientific SBE 19 plus V2 SEACAT profiler. All casts were concatenated into a master file and applied using the "Nearest in distance within time (4 hours)" profile selection method within CARIS.

Four holidays are present within the submitted surfaces as discussed in Section A.4. Pydro QC Tools 2 Grid QA was used to analyze H13478 multibeam echosounder (MBES) data density. The submitted H13478 variable-resolution (VR) surface met HSSD density requirements shown in the histograms below. Pydro QC Tools v.3.6.0 Flier Finder, with default settings, was used to identify sounding "fliers" in the finalized H13478 VR surface. Obvious noise was rejected by the hydrographer in Caris Subset Editor. After data cleaning, the Flier Finder tool was run again and identified one remaining flier in the Complete Coverage surface. This flagged node was investigated, deemed to be an accurate representation of a new wreck included in the Final Feature File (FFF), and has been retained in the submitted bathymetric surfaces.

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.
