Data provided by National Oceanic and Atmospheric Administration
A 10-m resolution gridded digital elevation model (DEM) grayscale hillshade for the bathymetry (ocean depth) surrounding Alamagan Island in the Commonwealth of the Northern Mariana Islands (CNMI) compiled from ship-borne multibeam sonar surveys merged with coastal bathymetry derived from multipectral IKONOS satellite data. Almost complete bottom coverage was achieved in depths between 0 and 800 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_10m_alamagan.html
