    • Rugosity 10 m grid derived from gridded bathymetry of Guguan Island, Commonwealth of the Northern Mariana Islands (CNMI), USA

    Metadata Updated: March 22, 2025

    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 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 environment of Guguan Island.
