    • Gridded multibeam bathymetry of Apra Harbor, Guam U.S. Territory

    Metadata Updated: March 22, 2025

    Gridded bathymetry from Apra Harbor, Guam U.S. Territory. The netCDF and Arc ASCII grids include multibeam bathymetry from the Reson SeaBat 8125 multibeam sonar collected in 2008 by the NOAA Office of Coast Survey and the United States Navy Fleet Survey Team. The sonar frequency is 455 kHz and the data are gridded at 1 m resolution. The data served here were extracted from a Caris project provided by OCS and converted to netCDF and Arc ASCII grids by the NOAA Coral Reef Ecosystem Division.
