| 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... |

| The Gulf of Capbreton is one of the first submarine canyons known in the world's oceans. A specimen sheet, based on soundings, was made by the Scientific and Technical Institute of Marine Fisheries. Moreover, west of the entrance of the English Channel, the studies conducted by E. Le Danois and L. Beaugé (1), who drew a map limited to the east by the shoal of la Chapelle, highlighted the complexity of the topography of the continental shelf at the two extremities of the great arc formed by this slope in the Bay of Biscay. |

| 1° the topography of the depression located east of the "Markhams Hole" of the "Fischereikarte der Nordsee" is quite different from that represented on the chart, but the observed depths are the same.2° the depression of the "Markhams Hole" does not exist. Where depths of 60 metres were indicated on the chart we only observed depths of 30 to 35 metres.3° the topography of the "Outer Silver Pit" is extremely complex; there is no doubt that another series of transversal transects would show more peculiar topographic accidents than those observed.However, we think that we have detailed enough this depression's main topographic lines to conclude that its model is mostly a Quaternary model of glacial or periglacial origin. The sedimentological study of the... |

| 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... |
