Hard and Soft Bottom Seafloor Substrate Map Derived from an Unsupervised Classification of Gridded Bathymetry Derivatives for the NOAA Habitat Blueprint West Hawaii Focus Area

Hard and soft bottom seafloor substrate data and maps for the NOAA Habitat Blueprint West Hawaii Focus Area (WHFA) in the Main Hawaiian Islands. Cell values in the raster datasets reflect whether the seafloor is hard bottom or soft bottom based on an unsupervised classification run using ArcGIS software with the Spatial Analyst extension. The classifications are based on bathymetry, acoustic de...
