Rugosity grid derived from gridded bathymetry of Ta'u Island of the Manu'a Island group, American Samoa

Description

Rugosity is derived from gridded (5 m cell size) multibeam bathymetry, collected aboard R/V AHI, and bathymetry derived from multispectral IKONOS satellite imagery using the Benthic Terrain Modeler with rugosity methods by Jeff Jenness (2003). Cell values reflect the (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 Ta'u Island of the Manu'a Island group, American Samoa.
