    • EK60 Water Column Sonar Data Collected During EX2401

    Metadata Updated: September 1, 2025

    From April 13 - May 4, 2024 (San Francisco, California to Honolulu, Hawai’i), NOAA Ocean Exploration conducted the 2024 Mapping Shakedown + High Seas Mapping expedition to test and calibrate the acoustic mapping and associated systems aboard the NOAAS Okeanos Explorer following a drydock period over the winter or 2023/2024. The primary focus of this expedition was to ensure readiness of all sensors and equipment for the 2024 field season. Shakedown and readiness operations included calibrations of the POS MV and Seapath positioning and attitude systems, geometric calibration of the EM304 MKII multibeam echosounder, multibeam swath accuracy assessment at expected operational depths for this field season, speed-noise tests, and calibrations of each of the EK60/80 split beam sonars.
