Data provided by National Oceanic and Atmospheric Administration
A 20-m resolution gridded digital elevation model (DEM) grayscale hillshade compiled from ship-borne multibeam sonar surveys for the bathymetry (ocean depth) surrounding Johnston Atoll in the Central Pacific Ocean, a U.S. Minor Outlying Island (USMOI). Almost complete bottom coverage was achieved in depths between 8 and 4100 m. Data collected by the Pacific Islands Benthic Habitat Mapping Center (PIBHMC) in support of NOAA's Coral Reef Conservation Program. Not to be used for navigational purposes. For the related dataset containing numeric bathymetry values for this image layer, see http://pacioos.org/metadata/pibhmc_bathy_20m_johnston.html
