    • H09814: NOS Hydrographic Survey , Chesapeake Channel, Virginia, 1980-10-09

    Metadata Updated: June 30, 2023

    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.

    Lineage NOS Survey data is collect by surface vessels of varying characteristics. The three primary sources of survey data are NOAA survey ships, national response teams, and contract vessels. The ships collect data, conduct basic on board data processing and then send these data to NCEI (formerly NGDC) for archival and "RAW" data. After archiving the RAW data NCEI sends the data to the processing branches (Atlantic or Pacific) for further processing. The processing branches complete processing of these data and generate products. The processed survey data is sent to NCEI for archival and the products are sent to the Hydrographic Surveys Division (HSD) for approval. Once products are approved by HSD, these survey products are sent to NCEI for archival and posting on-line.
