Etude des échantillons récoltés en Juillet - Août 1946 par « Le Président-Théodore-Tissier »

During the cruise carried out in 1946 by the "Président-Théodore-Tissier", Mlle Lalou and C. Francis-Boeuf conducted a number of samplings between Concarneau and Ireland, and so did I between Start-Point and Cherbourg. I attached to the study of these materials, that of the samples I had collected in June 1947 on board the escort vessel "Grenadier". The map (fig. 1) precises the nature and location of these samples and of those collected by Louis Dangeard in 1926 on board the "Pourquoi Pas?" and by Jean Furnestin and Léopold Berthois in 1935 and 1936 on board the "Président-Théodore-Tissier".
