Description Composite roughness theory is used to characterize Southern Ocean bottom backscatter (multibeam) data. Spectral parameters based on Helmholtz-Kirchhof's theory (1) are determined from measured near-normal incidence values. A splicing technique using Rayleigh-Rice theory (2) is employed beyond 20 degrees incidence angles. Estimated roughness parameters for six deep ocean areas correlate with geology
