Essai d'interprétation morphologique et tectonique des levés bathymétriques exécutés dans la partie sud-est du golfe de Gascogne

The bathymetric charts based on the measurements taken near the continental shelf between the Western part of Ireland and Cap Finisterre (Spain) have been published by the Scientific and Technical Institute of Marine Fisheries.These charts were completed between 1961-1963 each time the Institute of Marine Fisheries ("Président Théodore Tissier", then "Thalassa") vessels cruised the studied area, during their hydrology cruises and fishing surveys.But it became necessary to coordinate and complete the collected data by a bathymetry cruise. This cruise took place in 1964.During this last cruise, conducted with an Atlas-Echolot 601 echo sounder, the vessel's routes were immediately and permanently mapped, combining the information obtained through the Decca 1 and 8 chains of the radar on the Spanish coast and the loch gauging between the two navigation areas where electronic devices could be used.
