abstract= {The National Ocean Service (NOS) Estuarine Bathymetric Digital Elevation Models are gridded bathymetry datasets interpolated from 150 years’ worth of hydrographic survey data collected by the former NOS Special Projects Office. The initiative produced datasets for 70 estuaries in the conterminous United States with sufficient data coverage to support detailed bathymetric processing.

Use Cases

Bathymetric data adds another dimension to geographic mapping and modeling, and can be used as either a background layer or 3D surface for draping thematic maps such as benthic or marine organism habitats and geologic data. It also delineates the lower boundary of the water column in hydrodynamic models used to monitor and predict the movement of oil and hazardous materials, temperature and salinity distributions, animal migration patterns, and model storm surge and tsunami effects.
Data Characteristics

The perimeter of each bathymetry aligns with estuarine drainage area water boundaries determined by the NOS Coastal Assessment Framework. Elevations do not extend beyond the high water line. Bathymetric depths are vertically referenced to the local tidal datum, typically Mean Lowest Low Water (MLLW) averaged over a 19 year tidal epoch. There are no plans to produce bathymetries for other estuaries, but some existing bathymetries are updated as part of Coastal Digital Elevation Models, which can accessed through the Bathymetric Data Viewer application.
