Essai d'interprétation morphologique et géologique de la pente continentale à l'ouest de la péninsule Ibérique

Soundings in the west of the Iberian Peninsula aimed at extending the morphological identification of the continental slope all the way to the Cap Saint-Vincent (Portugal) started in 1956 from the Porcupine bank (west of Ireland).Works started during the cruises of the oceanographic research vessels of the Scientific and Technical Institute of Marine Fisheries: the "Président Théodore-Tissier" and the "Thalassa", as they were on their way to the Mediterranean Sea or other regions south of the Strait of Gibraltar.These first results were then completed during different research expeditions on fishing, off the Portuguese coast.This discontinuity in the operations, spread out over many years, resulted in all the navigation and soundings being conducted by Captain R. BRENOT. Cartography was realized by L. BERTHOIS. We aimed at establishing correlations between the morphology of the continental slope and the main structural alignments of the continent; P. AILLOUD conducted this part of the study.
