Description:

From September 23 – October 14, 2023 (Seward, Alaska to San Francisco, California), NOAA Ocean Exploration completed Seascape Alaska 6: Gulf of Alaska Transit Mapping (EX2307). Operations during this 22-day expedition included collection of 47,899 square kilometers of seafloor bathymetry (40,108 in the U.S. Exclusive Economic Zone). 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.
