    • EK60 Water Column Sonar Data Collected During EX2306

    Metadata Updated: July 1, 2024

    From August 23rd - September 14th, 2023 (Kodiak, Alaska to Seward, Alaska), NOAA Ocean Exploration conducted Seascape Alaska 5: Gulf of Alaska Remotely Operated Vehicle Exploration and Mapping (EX2306), a remotely operated vehicle (ROV) and mapping expedition to the Gulf of Alaska. Operations during this 23-day expedition included the completion of 19 successful remotely operated vehicle (ROV) dives, which were conducted in water depths ranging from 253.1 m to 4261.5 m for approximately 87 hours of bottom time and resulted in the collection of 383 samples. EX2306 also collected more than 28,000 sq. km of seafloor bathymetry and associated water column data using an EM 304 multibeam sonar. All data associated with this expedition will be archived within 120 days of the end of the expedition and will be publicly available through the NOAA Archives.
