Resumen

SANCHEZ, Alberto et al. Sediment transport patterns in Magdalena Bay, Baja California Sur, Mexico, inferred from grain-size trends. Lat. Am. J. Aquat. Res. [online]. 2010, vol.38, n.2, pp.167-177. ISSN 0718-560X.

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) acycloneic gyre in the deeper, central part and (2) an acycloneic gyre in the southeast part of the bay. The sediment transport pattern is highly correlated with the residual tidal currents in Magdalena Bay.
