We established a high-resolution stratigraphy in the Pliocene-Pleistocene and used it to compare glacial and interglacial sedimentation rates of turbidites and periplatform ooze. This stratigraphy is based on downhole variation of aragonite content in periplatform ooze, on nannofossil zonation, and on lithologic correlation with nearby Site 633, where aragonite stratigraphy was complemented with oxygen-isotope curves and magnetostratigraphy. The overall character of the aragonite curve is clearly visible. This curve is similar to the global oxygen-isotope curve, especially regarding the decreased amplitude downhole and the disappearance of 100 000-yr cycles. -from Authors
