NCEI and the IHO Data Center for Digital Bathymetry (DCDB) archive and share depth data acquired by hydrographic, oceanographic, and industry vessels and platforms during surveys or while on passage. These data, which are used in several national and international mapping bathymetry projects, are free to the public with no restrictions.
To submit bathymetric data to the archive, please review our instructions for contributing data. Contact mb.info@noaa.gov for more information.
This interactive map gives access to combined bathymetric and topographic data, including the ETOPO Global Relief Model.
