CRED Rugosity grid derived from gridded bathymetry of Tutuila Island, American Samoa, South Pacific
Description
Rugosity is derived from gridded (5 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 and (surface area) / (planimetric area) ratio for the area contained within that cell's boundaries. They provide indices of topographic roughness & convolutedness. This data set is for the shelf and slope environments of Tutuila Island, American Samoa, South Pacific.
