Abstract: The National Oceanic and Atmospheric Administration
(NOAA) has the statutory mandate to collect hydrographic data in support
of nautical chart compilation for safe navigation and to provide
background data for engineers, scientific, and other commercial and
industrial activities. Hydrographic survey data primarily consist of
water depths, but may also include features (e.g. rocks, wrecks),
navigation aids, shoreline identification, and bottom type information.
NOAA is responsible for archiving and distributing the source data as
described in this metadata record

Purpose: These hydrographic data are made available to the
public for a wide variety of uses, such as sea-bottom characterization,
habitat classification, coastal studies, boundary issues, and tsunami
forecasting. These data are not intended to be used for navigation.
Nautical charts produced and certified by NOAA should be used for
navigation purposes

Home page for digitized data from smooth sheets of hydrographic surveys completed between 1837 and 1965, and from survey data acquired digitally on NOS survey vessels since 1965. Over 76 million soundings from over 6,600 surveys are included. NGDC has developed an interactive map and data discovery tool, the Bathymetry Map Service, and a text-based search engine, the Hydrographic Survey Text Search, which enable rapid data discovery and download.
