    • Multibeam Backscatter Data for Selected U.S. Locations in the Pacific

    Metadata Updated: December 13, 2025

    Multibeam backscatter imagery extracted from gridded bathymetry for selected U.S. locations in the Pacific. The backscatter datasets include data collected using the RESON 8101ER multibeam sonar, Kongsberg 300 kHz EM3002D multibeam sonar, and a Kongsberg 30 kHz EM300 multibeam sonar. Data are available in GeoTIFF and NetCDF format as well as composite maps (jpg or PDF) which show all available data for a region. Please see the individual metadata records for additional information about a specific location.
