The multi-beam bathymetry survey was carried out at Fifty Fathom Flat (FFF) off Bombay High and Murud Janjira in western continental margin of India (WMCI). The multi-beam data provides concurrent bathymetry and backscatter involving the large-scale and small scale seafloor roughness. Here, the seafloor characterization is initiated by employing the multifractal detrended fluctuation analysis (MFDFA) of multi-beam data acquired from FFF. The bathymetry survey was carried in area of carbonate platform off western India, comprising of one area on the platform and two at the upper slope of the platform. The bathymetry from the carbonate platform area shows elongated linear ridges across the platform. It is indicated from the bathymetry that the platform was dissected into smaller portions at 90m depth and channels eroding the platform were merged into streams directed towards slope. These channels finally merged into larger streams which became wider and deeper at 700m contour. We estimate fluctuation function Fq(s), Hurst Exponent h(q) , multifractal scaling exponent T(q) and multifractal spectrum f(α) parameters using multibeam bathymetry and backscatter data. The multifractal spectrum of different bathymetry and backscatter profiles and related width parameter, Δh(q), Asymmetry and Δf(α ) are observed to well clustered defining the seafloor regions in the FFF.
