Bathymetry (Ocean Depth)

Digital elevation models (DEM) of the seafloor, also known as bathymetry. Available for the state of Hawaiʻi and other U.S.-affiliated Pacific Islands throughout Polynesia and Micronesia at varying resolutions and data sources, including ship-borne multibeam sonar surveys merged with or without satellite- and/or aerial-derived bathymetry. Also provided globally at 1-km resolution from SRTM30+ v11.

NOTE: Datasets are listed in the pull-down menu by location and spatial resolution (e.g. "Guam: 10m").
