Análisis geoestadístico de los canales submarinos en el talud superior del Golfo de Cádiz (SO de la Península Ibérica)

Abstract

Five different groups of gullies have been distinguished along the northeastern slope of the Gulf of Cádiz using geostatistical analysis. A Grouping Analyst has been carried out to six morphological variables of the gullies: area, straight line length, width/depth ratio, width, depth and stream order. The spatial distribution of the identified five groups and their mean characteristics have allowed us to propose an evolutionary model for the two zones of the upper continental slope. This model is related to the local physiography, the sediment supply, the tectonic control and the oceanographic regime.
