Description:From June 5-20, 2023 (Dutch Harbor, Alaska to Kodiak, Alaska), NOAA Ocean Exploration conducted mapping operations off the coast of the Aleutian Islands in U.S. waters, aiding in closing bathymetric gaps within this region. Expedition EX2303 collected 36,980 square kilometers of bathymetry and associated water column data within the U.S. Exclusive Economic Zone and Territorial Sea deeper than 200 m. During mapping operations, NOAA Ocean Exploration simultaneously collected EM 304 multibeam sonar bathymetry observations and Simrad EK60/EK80 split-beam fisheries sonar observations of biologic material in the water column, as well as Knudsen 3260 sub-bottom profiler observations of sub-seafloor geologic structure and sediment.
