Fig. 1

Two 3D dives examples. These dives have about the same depth but show two contrasting situations: on the left (a and b) the first main component explains a very large part of the total dispersion while on the right (c and d), the dispersion explained by the first main component is particularly low. The blue part represents the dive’s bottom phase. The black points give location of starting points. The orange ellipses stand for the 2D projections of a 3D ellipsoid whose axis are the three main components. On the “Map views” (a and c) the orange line display the direction of the first main component which is used to construct the best “Profile Views” (b and d).
