Obtain bathymetry data using GEODAS Design-a-Grid

The National Oceanic and Atmospheric Administration (NOAA) has produced the National Geophysical Data Center (NGDC) website to allow for US data access. Oceanic bathymetry can be found using GEODAS (GEOphysical DAta System) Grid Translator Design-a-Grid.

Details:

  • Must indicate latitude and longitude degree boundaries
  • Three format choices all available with headers:
  1. Binary Raster
  2. ASCII Raster
  3. XYZ Delimited
  • Downloads are free (no cost).

Obtain estuarine bathymetry data from NOAA's NOS

The National Oceanic and Atmospheric Association (NOAA) has produced the National Ocean Service (NOS) Estuarine Bathymetry website to allow for US estuarine bathymetry access.

Details:

  • Estuaries divided into six regions:
  1. North Atlantic
  2. Middle Atlantic
  3. South Atlantic
  4. East Coast Gulf of Mexico
  5. West Coast Gulf of Mexico
  6. Pacific Coast
  • 4 downloadable options of individual estuaries in *.dem format:
  1. 1 Arc Second (30 meter resolution) – Split into 7.5" quads
  2. 1 Arc Second – One big file
  3. 3 Arc Seconds (90 meter resolution) – Split into 1 degree quads
  4. 3 Arc Seconds – One big file
  • Downloads are free (no cost).


Topographic and Bathymetric Data Inventory


Obtain topographic and bathymetric data from the Topographic and Bathymetric Data Inventory

The National Oceanic and Atmospheric Association (NOAA) offers topographic and bathymetric data from the NOAA coastal Services Center and the Federal emergency Management Agency through the Topographic and Bathymetric Data Inventory. This resource provides both topographic and bathymetric data for the coastal areas of the United States. More information on this resource can be found here.
