Abstract

Procédé et dispositif d'exploration sismique en mer dans lesquels on utilise un canon à air pour émettre des signaux acoustiques. Le canon est placé de préférence à une profondeur de 3 mètres de façon que le signal de bulle soit réduit par l'écho de surface. Utilisable notamment pour les mesures sismiques dans les forages en mer.
