    Metadata Updated: March 28, 2026

    Multibeam, split-beam, and/or ADCP sonar mapping operations will be conducted 24 hours a day throughout the cruise. Sub-bottom profile mapping will be conducted periodically during the cruise for testing purposes and is subject to the discretion of the CO. XBT and/or UnderwayCTD sound velocity casts in support of multibeam sonar mapping operations will be conducted at an interval defined by prevailing oceanographic conditions, but not to exceed 6 hours. Multibeam data will be fully processed according to standard onboard procedures and will be archived with the National Centers for Environmental Information (NCEI). Split-beam EK60 data and ADCP data will be archived in their raw formats with NCEI as well.
