Rugosity grid (5 m) derived from gridded bathymetry of the US Territory of Guam

Published by Pacific Islands Benthic Habitat Mapping Center (PIBHMC), Coral Reef Ecosystem Division (CRED), Pacific Islands Fisheries Science Center (PIFSC), National Marine Fisheries Service (NMFS), National Oceanic and Atmospheric Administration (NOAA) | National Oceanic and Atmospheric Administration, Department of Commerce | Metadata Last Checked: January 27, 2026 | Last Modified: 2011-03-04T00:00:00.000+00:00
Rugosity is derived from gridded (5 m cell size) bathymetry from four sources: Multibeam bathymetry collected by Coral Reef Ecosystem Division aboard NOAA R/V AHI, and NOAA Ship Hi'ialakai; multibeam bathymetry collected in Apra Harbor by the Naval Oceanographic Office and NOAA Office of Coast Survey; lidar collected by the Naval Oceanographic Office; and lidar collected by the Joint Airborne Lidar Bathymetry Technical Center of Expertise. Rugosity is derived using the Benthic Terrain Modeler with rugosity methods by Jeff Jenness (2003). Cell values reflect the surface area to planimetric area ratio for the area contained within that cell's neighborhood. They provide indices of topographic roughness & convolutedness. This data set is for the shelf environment of the US Territory of Guam.
