Figure F10. Graphic age models for Sites (A, C) 1081 (Walvis Ridge) and (B, D) 1082 (Walvis Basin). Line connecting control points = best guess for age-depth model. "Nanno" = biostratigraphy (Giraudeau et al., 1998), "Pmag" = magnetic reversals (Shipboard Scientific Party, 1998g, 1998h), "Cycles" = based on inspection of variations in magnetic susceptibility, heavy line = estimated sedimentation rate (secondary y-axis). Upper and lower panels of each pair (A, C and B, D) differ in scale plotted (not in data points).
