The Gulf of Gabès (Souther Tunisia) belongs to the Pelagian Sea. This Gulf was studied at high resolution along its coast, and at a low resolution (oil industry resolution) offshore. These studies indicate quite abnormal conditions for a Mediterranean platform. Slopes are very limited, the tidal range reaches 2m which is exceptional for this sea a carbonate-dominated system and a system of incised valleys that are badly known. These valleys have been used as sediment drains during the Pleistocene wet periods intervals. Our objective is to acquire geophysical (sparker) data to build a detailed high-resolution stratigraphic framework differentiating auto- and aloo-cyclic processes. We want to make the link between the sediment dynamics, the important climatic changes of the region between high and low sea level conditions and between dry and wet periods.
