dc.description.abstract In this letter, the characterization of two coral banks is initiated employing the multifractal detrended fluctuation analysis (MFDFA) for multibeam bathymetry and associated backscatter data. The seafloor roughness was estimated using the Hurst exponent of a second-order moment. The two coral banks are located around the buried channels off Malpe, western continental margin of India (WCMI). The Gaveshani bank is lying on a submerged headland with high backscatter strength. The presence of greater seafloor roughness and medium multifractality in the backscatter data series indicates less heterogeneity of the involved process. In an evolutionary process, the Gaveshani bank may not be affected by the paleochannels. Contrary to the Gaveshani bank, another unnamed coral bank located on lowland and with lower backscatter strength shows lower seafloor roughness and greater multifractality, comparatively. This smoothness is due to the considerable heterogeneity of the seafloor process of a paleochannel system. During the Holocene period, the waves and the current action have further modified the morphology of the coral banks. To support the present analysis, we have juxtaposed the multifractal data analysis of seepage and nonseepage seafloor off Goa, WCMI, along with the coral banks
