Los campos de ondas de arena en la Plataforma Continental del Golfo de Cádiz entre Chipiona y Zahara de los Atunes

Abstract

The analysis o f the seafloor g éom orpholo gie features In the c o n tin e n ta l s h e lf o f the C u lf o f Cadiz with high resolution seismic profiles reveals a well defined distribution pattern of bedforms controlled by the morphology and the hidrodynamic of the area. Three zones are differentiated according to the bedform types and the hidrodynamic processes: a) a northern, shallow submarine zone at 30 m depth situated between ConiI and Barbate (Barbate ridge), where sand waves migrate towards the SE; b) a southern zone southward of the Barbate ridge, where sand waves migrate towards the NW, and c) the infralittoral-inner shelf between Coni! and Cadiz Bay, where sand waves migrate towards the SE and also are influenced by the waves action
