Description
Rugosity is derived from gridded (5 m cell size) bathymetry, from three sources: Multibeam bathymetry collected by Coral Reef Ecosystem Division aboard NOAA R/V AHI, and NOAA Ship Hi'ialakai; Multibeam bathymetry collected aboard the US Naval Ship Sumner, and lidar, both collected by Naval Oceanographic Office; and bathymetry derived from multispectral IKONOS satellite imagery. Rugosity is derived 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 Tinian and Aguijan Islands, and Tatsumi Bank, Commonwealth of the Northern Marianas (CNMI).
