dc.description.abstractGrain size statistical parameters of the surface sediment samples collected from the innershelf off Gopalpur were calculated using graphic and moment methods. Fine-grained sand present up to 15 m water depth shows symmetrical skewness and good sorting. These are leptokurtic. The coarse-grained sand beyond 15 m water depth has positive or negative skewness and moderate sorting. These are platy kurtic. Bivariate plot of mean vs skewness indicates two types of sample spread, keeping approximately 2.3 Phi mean as the demarcating boundary suggesting the presence of dune and beach types of sands. The study of log-probability sub-populations further supports these two types of sand as dune with single dominant saltation and beach with two distinct saltation populations. CM patterns suggest the role of rolling and graded suspension. The irregularity observed in bathymetry coincides with difference in the nature of sands within and beyond 15 water depth. The behaviour of the grain size parameters and the associated bathymetric features suggest the presence of relict environments of dune and beach
