Fig. 6. Spatial distribution of: (a) resident soil chloride concentrations with respect to layering; (b) mass recovery (M_j); (c) mean travel (E_j[z]) and modal transport depth; and (d) variance (V_j[z]) of the intensive transect. Mean travel depth is represented by triangles, and modal transport depth is represented by circles. The dashed reference lines represent the transect average value of that depth moment.
