dc.description.abstract We attempt here to quantify and model physiographic phenomena off the central west coast of India in terms of power spectral exponent, amplitude parameter. The statistical analysis of the multibeam echosounder grid bathymetry data is able to characterise the outer shelf, upper slope, shelf margin basin, and several structural rises. The scatter diagram analysis shows that the seafloor can be grouped in two distinct clusters. Distinctly different clustering patterns are observed over the structural rises compared to shelf, slope, basinal areas. This may suggest different modes of formation for the members of these two clusters. In fact, the steep and sharply elevated structural rises appear to be part of NW-SE trending coast parallel Mid-Shelf Basement and Prathap ridges. These ridges are rift-induced volcanic emplacements on a stretched and thinned continental crust which probably formed during mid- Cretaceous times.
