La cartographie par balayage des fonds marins constitue un [...] développement des techniques acoustiques facilitant le ciblage des ressources démersales à l'intérieur de bandes étroitement définies et souvent de formes très irrégulières. Ces méthodes fournissent des images de haute définition des profils bathymétriques et facilitent le chalutage contrôlé, de telle sorte que les marins peuvent éviter les zones où ils risquent de perdre le matériel de pêche, ou de toucher le fond [...] La cartographie par balayage représente l'équivalent de la cartographie topographique terrestre pour le plus grand bien des patrons de pêche. 2, record 1, French, - cartographie%20par%20balayage
