NOAA Survey H13670, located in Lake Erie within the sub locality of 8 NM Northwest of Presque Isle, was conducted in accordance with coverage requirements set forth in the Project Instructions OPR-W386-TJ-22 (Figure 1). 42.18666111111111 80.539425 42.21136666666667 80.13910277777778 Survey layout for H13670, plotted over ENC US4PA21M. The dashed black line represents the survey limits set forth by the OPR-W386-TJ-22 Project Instructions SupportFiles\Survey Overview.jpg Survey data were acquired in accordance with the requirements set forth by the Project Instructions (PI) and the Hydrographic Survey Specifications and Deliverables (HSSD) dated March 2022. The survey area is approximately 53 square nautical miles. The Port of Cleveland is one of the largest ports in the Great Lakes and ranks within the top 50 ports in the United States. Roughly 13 million tons of cargo are transported through Cleveland Harbor each year supporting over 20,000 jobs and $3.5 billion in annual economic activity(1). This project will provide modern bathymetric data for the Cleveland area as well as the vicinity of South Bass Island and Presque Isle. The project area was identified as a statistically significant hot spot within the 2018 hydrographic health model, a risk model that Coast Survey uses for evaluating priorities based upon navigational risks and the necessary quality of data to support modern traffic. Most of this area has not been surveyed since the 1940s, and experiences significant vessel traffic. A modern bathymetric survey in this area will identify hazards and changes to the seafloor, provide critical data for updating National Ocean Service (NOS) nautical charting products and improve maritime safety. Survey data from this project is intended to supersede all prior survey data in the common area. (1)http://www.portofcleveland.com/ The entire survey is adequate to supersede previous data. Complete coverage requirements were met utilizing 100% multibeam echo sounder (MBES) coverage as specified by the 2022 HSSD. Data Acquired in H13670 mets survey quality standards specified in the 2022 HSSD, including crosslines (see section B.2.1), NOAA allowable uncertainty (see section B.2.2), and density requirements (see Section B.5.2).

S222 collected 82.6 linear nautical miles of MBES crosslines and, or 4.15% of mainscheme MBES data. The crosslines acquired represent good spatial and depth diversity for the assigned survey area (Figure 5). A variable resolution (VR) Combined Uncertainty and Bathymetry Estimator (CUBE) surface of mainscheme data and a VR CUBE surface of crossline data were differenced using the "Compare Grids" tool in Pydro Explorer 19. The resulting mean was 0.04 m with a standard deviation of 0.06 m (Figure 5). Over 99.9% of nodes were compliant with IHO fraction of allowable error standards (Figure 6).

Sonar system quality control checks were conducted as detailed in the quality control section of the DAPR. None Exist There were no conditions or deficiencies that affected equipment operational effectiveness. Sound Speed Refractions H13670 is located in an area that exhibits intense thermal stratification. This layering greatly affects sound speed (Figures 10) and results in refraction that can be observed in the MBES surface (Figure 9). The impacts on sounding depth accuracy are within allowable uncertainty standards, as outlined in the 2022 HSSD.

SupportFiles\SVP issues.jpg Examples of intense thermocline in sound speed data collected in Lake Erie on H13670 across 24 MVP-200 casts from Julian Day 197. SupportFiles\H13670_DN197_Plot_Sound_Speed.png Static conductivity, temperature, and depth (CTD) casts were conducted at the start of acquisition each day and at a minimum of one every four hours during acquisition using an MVP 200 and Sea-bird Seacat 19+ V2 CTD. Cast frequency was increased in areas where a change in surface sound speed greater than two meters per second existed. All sound speed methods were used as detailed in the DAPR. A total of 197 sound speed profiles were collected as part of acquisition of H13670 and display good spatial diversity (Figure 11). Five of these casts were located outside of the sheet limits. One cast is 1220 meters away from the assigned survey limits, but the profile is not applied to the survey data set. Sound Speed Profiles acquired are representative of the entire survey area. All sound speed profile data were concatenated into a master file for the sheet. MBES data were corrected by applying profiles nearest in distance in time (4 hours) using this master file.

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.
