            <hsd:topic>
                <hsd:discussion>This survey is to support the proposed Lake Ontario National Marine Sanctuary (NMS) that would encompass over 1,700 square miles of eastern Lake Ontario. Originally nominated by four Lake Ontario counties, with support from New York State, the sanctuary would manage and protect underwater cultural resources. When designated (estimated in Fall of 2023), NOAA will start implementing its Management Plan. The plan includes surveying, inventorying, and documenting cultural resources; installing mooring buoys at some shipwreck sites; developing education and interpretive programs for schools and the public; creating a NOAA “presence” in the Lake Ontario communities; and promoting this area for tourism and economic development. As all Great Lakes waters are state-owned, NOAA will co-manage this with the State of New York.

The Lake Ontario NMS would be the third NMS in the Great Lakes, following Thunder Bay in Lake Huron (designation 2000) and Wisconsin Shipwreck Coast in Lake Michigan (designated in 2021). These three areas provide an amazing opportunity to interpret the history of the Great Lakes and how it contributed to the growth of our nation.</hsd:discussion>

                    <hsd:discussion>Thomas Jefferson acquired 34.8 nautical miles of multibeam crosslines or 7.0 % of mainscheme lines across most depth ranges and multiple boat days. H13673 crossline data is adequate for verifying and evaluating the internal consistency of survey data. The Compare Grids function in Pydro Explorer analyzed finalized variable resolution (VR) surfaces of H13673 crossline-only data and mainscheme-only data. In the difference surface, the resulting mean was -0.05 m with a standard deviation of 0.28 m; 100 % of nodes met IHO allowable Total Vertical Uncertainty (TVU) standards. See figures below for specific details on crossline analysis.</hsd:discussion>

The hydrographer reviewed the flagged grid nodes, considers them to be accurate representations of the lake bed, and has retained them in the final delivered surfaces. There are no holidays present in the coverage achieved. All bathymetric grids for H13673 meet density requirements per the 2022 HSSD. See figure bellow for more information.</dr:discussion>
