Geochemistry and physics on sediment cores from the Peru Basin, supplement to: Weber, Michael E; Wiedicke-Hombach, Michael; Riech, Volkher; Erlenkeuser, Helmut (1995): Carbonate preservation history in the Peru Basin: Paleoceanographic implications. Paleoceanography, 10(4), 775-800

We studied preservation/dissolution cycles and paleoproductivity in eight sediment cores from the Peru Basin south of the highly productive surface waters of the eastern equatorial Pacific. Stratigraphy is based on stable oxygen isotopes and on combined magnetostratigraphy and biostratigraphy. Sediment cores which span the last 8 m.y., were retrieved during cruise 79 with RV SONNE close to the carbonate compensation depth (CCD). In general, sediments show Pacific-type carbonate cycles. We interpret a pronounced carbonate peak...
