Slope Grid Derived from Gridded Bathymetry for Select U.S. Locations in the Pacific

Slope is derived for islands and banks across the U.S. Pacific Islands Region primarily from gridded multibeam bathymetry collected aboard NOAA Ships Hi'ialakai and Oscar Elton Sette, and aboard R/V AHI (Acoustic Habitat Investigator) from 2003 to 2012 by the NOAA Coral Reef Ecosystem Program (CREP). Other sources of available data used to derive slope for a few locations include estimated depths derived from IKONOS satellite imagery from 2000 to 2002, LIDAR data from 2001 and 2007, and multibeam bathymetry collected in 2001 and 2002. Slope grid cell values reflect the maximum rate of change (in degrees) in elevation between neighboring cells derived with the ArcGIS Spatial Analyst extension. The slope grids generated for each location are available via the Pacific Islands Benthic Habitat Mapping Center (PIBHMC) wesite at The data, associated map products, layer files, and detailed documentation (more specific than this pacific-wide record) about the data sources are included in a zip file for each location.
