The main aim of the surveys was to test a range of physical environmental parameters of nearshore reefs in southeast Tasmania as surrogates to predict patterns of benthic biodiversity. Two data sets were collected: (1) high-resolution bathymetry and seabed acoustic reflectance (backscatter) from a multibeam system and (2) high-resolution spatially rectified stereo still photographs of the seafloor collected by an autonomous underwater vehicle. In this analysis, the degrees of change of the slope of the seabed over a distance of 6 m and the seabed morphology are examined as surrogates for classifying seabed substrate. The distribution of the biological communities over different seabed morphologies is examined as a first step in the process of linking biological data to seabed substrate.
