L'invention permet d'effectuer en mer des relevés séismiques simultanés des fonds marins et du site. Un navire hydrographique remorque à la fois un réseau de sismographes de fond (6, 18, 20) et un réseau de sismographes de site (6, 16, 20). Les réseaux fonctionnent séparément mais peuvent comporter certaines parties communes.
