| La comparaison des dynamiques sédimentaires sur deux portions de marges continentales, Verrill Canyon en Nouvelle Ecosse et Mériadzek dans les Entrées de la Manche, révèle l'existence de multiples processus sédimentaires qui peuvent se diviser en deux grandes familles : les processus de dépôt et les processus d'érosion ou de rupture. |

| The presence of gas is a common feature in many seismic sections. However, the origin of the gas is often difficult to determine. Recently acquired very high resolution seismic profiles using an IKB Seistec boomer provide useful insight to the understanding of the gas origins in a range of environmental settings including sea lochs and coastal lagoons. The gas features are described both from a qualitative point of view through their acoustic facies, and quantitatively through the associated seismic signal (polarisation, amplitude). Acoustic facies include acoustic turbidity, gas "curtains" and "blankets" as well as "white fringes" and "black shadows". All the features encountered have been related to specific gas nature generated by different sources... |
