EK60 Water Column Sonar Data Collected During EX2302

Description

From May 5 – 26, 2023 (Seattle, Washington, to Dutch Harbor, Alaska), NOAA Ocean Exploration conducted transit and mapping operations off the coast of Washington State, the Gulf of Alaska, and along the Aleutian Islands. The ship departed from Seattle, Washington. Expedition EX-23-02 collected data supporting the Seascape Alaska initiative and used a small, human portable AUV in partnership with the Defense POW/MIA Accounting Agency (DPAA) to aid in locating an aircraft lost in the Aleutian Islands during World War II. Transit mapping data was collected from Seattle, Washington, across the Gulf of Alaska, and along the northern and southern edges of the Aleutian Islands, extending from approximately Unga Island to Gareloi Island. Primary mapping activities focused on the area connecting the Aleutian Arc and the southern end of Bowers Ridge and the area surrounding Bogoslof Island. The ship returned to port in Dutch Harbor, Alaska. The exploratory mapping operations conducted on this expedition will aid in future characterization of these unexplored areas and help initial characterization in the region.
