Thank you. We hesitated on this point but decided to keep the figure in as the quality of the seismic in the shallow level is really crucial to the discussion. We need to know if the interpretation is reliable, especially in this shallow zone that is not well imaged by this type of data. A misinterpretation can led to the targeting of circulation pathways that are in fact only artefacts.
Figure 4: This figure could go in the appendix. It is good to let the reader know that not all seismic surveys provided the same quality, but this is more a technical point.
