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.
