Rugosity 60 m grid derived from gridded bathymetry of Rota Island, Mariana Islands, USA

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: February 02, 2026 | Last Modified: 2009-04-07T00:00:00.000+00:00

Rugosity is derived from gridded (60 m cell size) multibeam bathymetry, collected aboard NOAA Ship Hiialaka'i and R/V AHI, 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 and slope environments of Rota Island.
