The bathymetry data were used to develop eight complexity surfaces: bathymetry mean, bathymetry stdev, curvature, curvature plan, curvature profile, rugosity, slope, and slope of slope. These layers were used in a Principle Component Analysis (PCA) that was used to generate the benthic habitat map using object oriented image processing software as described in Costa and Battista, 2013.
