    Lineage information for: series
    Lineage Statement Multibeam data is collected by vessels of varying characteristics including ships, small boats, remotely operated vehicles (ROVs), and autonomous underwater vehicles (AUV). The NOAA National Centers for Environmental Information (formerly NGDC) archive raw data, processed data, and associated products. All data and products are made available to the public via NCEI's map services and search interfaces.
