To better understand the physical characteristics of sedimentary deposits in Lake Geneva, we acquired and processed very high resolution seismic reflection data. Accurate amplitude measurements were obtained after correction for the frequency response of the hydrophones which were individually calibrated. In a first part, we present the acquisition and the pre-processing done on these data to correct the amplitude. In a second part, we migrate the data using a preserved amplitude pre-stack depth migration, and then apply a post-migration processing in order to correct for residual move-out. Finally, AVA analysis enables to differentiate sedimentary unit boundaries.
