Abstract


The grain-size trend analysis (grain size, sorting asymmetry) was determined at 58 stations in order to infer the residual vectors of sediment transport in Magdalena Bay, Baja California Sur, Mexico. Grain-size trend analysis and principal components analysis were applied to textural sediment parameters. The results indicated that well-sorted sediment is associated with fine to very fine sand. The residual vector transport suggests the presence of two gyres in the dispersion of clastic material: (1) acyclone-ic gyre in the deeper, central part and (2) an anticyclone-ic gyre in the southeast part of the bay. The sediment transport pattern is highly correlated with the residual tidal currents in Magdalena Bay.
