Description

For the Learn ArcGIS lesson Find ocean bathymetry data.
This is a DEM tif file that maps the seafloor east of Virginia Beach and includes the Norfolk Canyon and Currituck Slide Complex.
This data was extracted from the larger netCDF file found here: U.S. Coastal Relief Model Vol.2 - Southeast Atlantic, provided by the National Centers for Environmental Information (NCEI) and National Oceanic and Atmospheric Administration (NOAA).

NOAA National Geophysical Data Center. 1998: U.S. Coastal Relief Model Vol.2 - Southeast Atlantic. NOAA National Centers for Environmental Information. https://doi.org/10.7289/V53R0QR5. Accessed March 2022.

NGDC's U.S. Coastal Relief Model (CRM) provides the first comprehensive view of the U.S. coastal zone integrating offshore bathymetry with land topography into a seamless representation of the coast. The CRM spans the U.S. East and West Coasts, the northern coast of the Gulf of Mexico, Puerto Rico, and Hawaii, reaching out to, and in places even beyond, the continental slope. Bathymetric and topographic data sources include: NGDC's NOS hydrographic surveys, multibeam bathymetry, and trackline bathymetry; the U.S. Geological Survey (USGS); and other federal government agencies and academic institutions. Bathymetric contours from the International Bathymetric Chart of the Caribbean Sea and the Gulf of Mexico project were also used. Digital elevation models (DEMs) of the Great Lakes, Southern Alaska, and high-resolution DEMs of U.S. coastal communities and territories are also available.
