Data provided by National Oceanic and Atmospheric Administration
A global 1-km resolution bathymetric digital elevation model (DEM) grayscale hillshade of the ocean floor. Derived from the SRTM30+ v11 dataset produced at Scripps Institution of Oceanography from United States Geological Survey (USGS) 30 arc-second SRTM30 gridded DEM data, itself a product of NASA's Shuttle Radar Topography Mission (SRTM). Bathymetry are based on the Smith and Sandwell global 1 arc-minute grid between latitudes +/- 81 degrees. Higher resolution grids have been added from the LDEO Ridge Multibeam Synthesis Project, the JAMSTEC Data Site for Research Cruises, and the NGDC Coastal Relief Model. Arctic bathymetry is from the International Bathymetric Chart of the Oceans (IBCAO). For the related dataset containing numeric bathymetry values for this image layer, see http://pacioos.org/metadata/srtm30plus_v11_bathy.html
