Rugosity Derivative Surface used to characterize the complexity of the seafloor around St. John, USVI
Rugosity was calculated from the bathymetry surface for each cell using the "Rugosity" function in the Benthic Terrain Modeler toolbox (Jenness 2002, 2004; Wright et al., 2005). Rugosity is defined as the ratio of surface area to planar area within a square 3x3 cell neighborhood. Rugosity values near 1 represent flat, …
