    • EX2208: EXPRESS: West Coast Exploration 1 (Mapping)

    Metadata Updated: October 19, 2024

    From October 16-November 3, 2022 (San Diego, California to Newport, Oregon), NOAA Ocean Exploration conducted mapping operations off the coast of California and Oregon in U.S. waters, aiding in closing bathymetric gaps within this region. Expedition EX-22-08 collected 32,416 square kilometers of bathymetry and associated water column data, 22,313 square kilometers of which were within the U.S. Exclusive Economic Zone and Territorial Sea deeper than 200 m, while 10,104 square kilometers were collected in international waters. 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. A detailed sub-bottom survey targeted previously-identified sponge reefs in the Channel Islands National Marine Sanctuary. The exploratory mapping operations conducted during this cruise will provide initial characterization of the region, as well as data to support further exploration.
