Notes: Assignments of ages to depths below seafloor are based on nannofossil stratigraphy and paleomagnetic reversals with information from cyclic stratigraphy, in cases (see Figs. F8, F9, F10, F11, F12). The assignments are not precise. Decimal digits are given to preserve apparent sedimentation rates. Errors of age assignment are routinely of the magnitude 0.01 m.y. and greater.
