- Morphological and sedimentological assessment of submarine dune fields on the coast of Yucatan, Mexico Eduardo Cuevas María de los Ángeles Liceaga-Correa Luis A Rincón-Sandoval Guadalupe Mexicano-Cíntora Leonardo Arellano-Méndez Jorge I Euán-Ávila Héctor Hernández-Núñez Sandor Mulsow Ciencias de la Tierra sub Dune field sedimentology dune morphology bottom profiles Conspicuous sedimentary deposits forming well-structured and prominent submarine dunes are found on the coast of Yucatan (Mexico), close to the ports of Dzilam de Bravo, San Felipe, and El Cuyo. The objective of this study was to evaluate the morphological and sedimentological features of these submarin e dunes. Sub-bottom seismologic profiles we re obtained and standardized sedimentolog icalanalyses were performed on sedi ment samples collected at the three study sites. Both the height and wavelength of dunes were di fferent between the three sites, mean heights ranging from 0.84 to 2. 28 m and mean wavelengths from 98 to 330 m. Most of the dunes show ed a well- marked asymmetry, which is related to the direction of their movements. Their granulometric co mposition was dominated by medium , moderately well-sorted sa nd. This study provides bases for futu re systematic monitoring of th ese peculiar ecosystems, including information to be considered for the evaluation of their ecological role in the marine system. 2013 editorial 0185-3880 https://www.redalyc.org/articulo.oa?id=48025656002 en http://www.redalyc.org/revista.oa?id=480 Ciencias Marinas application/pdf Universidad Autónoma de Baja California Ciencias Marinas (México) Num.1 Vol.39
