Seafloor Rugosity, 5m - Tutuila, American Samoa

Metadata Updated: October 14, 2022

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 and convolutedness. This data set is for the shelf and slope environments of Tutuila Island, American Samoa, South Pacific.
