Fig. 2: Late Pliocene and Pleistocene geochemical records from Site U1532.
From: Late Pliocene growth of the West Antarctic Ice Sheet to near-modern configuration
a Bulk detrital sediment Nd isotope compositions (εNd) (error bars are 2 SD external reproducibility) record from IODP Site U1532 (this study) together with earlier published records of bulk detrital records (<63 μm fraction) ANT34/A2-10 (Lat: 125.58°W, Long: 67.03°S)22, (b, c) Bulk detrital sediment Pb isotope records from the site U1532. The error bars are smaller than the symbols in the Pb isotope data. d Ratio of total organic carbon and nitrogen percentage (TOC/TN). e Sediment reflectance a*. f Average sedimentation rates. The data of the panels (d−f) are published in the IODP proceedings27 and are also available in the IODP data portal (https://web.iodp.tamu.edu/OVERVIEW/). g Global benthic δ18O (LR04) curve44. Colour bank indicates climate transitions; iNHG-intensification of Northern Hemispheric Glaciations and mPWP-mid Pliocene Warm Period. h Lithological log46 of sediment core U1532A, B.
