Figure 6- a) Vertical profiles concern 1992 and 1998 surveys (DIGICART 40). Every measured point is represented by a
symbol. The full circle concern the measures realized in 1992 and the cross concerns the outline of 1998. b)
Punctual differences between the vertical profiles of 1998 and that of 1992. In the abscissa there are the
shifting in depth while in the ordinate the y-coordinates.
