|This Roman shipwreck at Basses de Can, to the south of the Cap de Saint-Tropez, is resting in an area measuring 80 x 90 metres. It was assessed in 1987 using the single-seat submarine Nérée. Archeologists directed the mission from the surface via a videoscreen and an intercom.|

to the front of the small submarine.
It is a Dressel 1A amphora dating to the second century BC.
This diagram shows the laying down of the two-metre long graduated metal rulers with the remote-controlled arm of the submersible. Also visible are three reference grids that serve as the basis for the topographical map: the sections mark the longitudinal axis of the ship. Along this alignment, the rulers are positioned one by one with the remote-controlled arm of the submarine, running along the whole length of the site. While the pilot at the controls of the craft simultaneously manipulates the heading and trim of the Nérée, the video camera records the data of the measurements that are taken.
