Appropriate type of seismic must be chosen to image geological targets (according to their depth and size). Here, we want to emphasize, that the use of nested seismic data of increasing resolution simultaneously enables a better seismic stratigraphic interpretation. <br>To illustrate our purpose we will present a series of seismic profiles of different resolution but at the same position that enable a comparaison of different vertical scale and variable resolution (from Kilometric conventional seismic, to high resolution, very high resolution and ultra high resolution seismic data) coming from the same area in the Gulf of Lion. <br>
