• Description:
  From July 14 - 25, 2023 (Kodiak, Alaska, to Dutch Harbor, Alaska), NOAA Ocean Exploration conducted the Seascape Alaska 3: Aleutians Remotely Operated Vehicle Exploration and Mapping expedition (EX2304). This remotely operated vehicle (ROV) and acoustic mapping exploration expedition offshore of the Aleutian Island Chain included the completion of 8 ROV dives (two were aborted before reaching the seafloor), which were conducted in seafloor depths ranging from 533 m to 2,807 m for approximately 22.5 hours of bottom time and resulted in the collection of 95 samples. EX2304 also mapped 16,475 sq. km of seafloor (16,433 sq. km within the U.S. Exclusive Economic Zone).
