Timeseries of binned benthic stable carbon isotope from ODP Site 162-982,130-807 and ODP Site 162-982

This dataset contains C. wuellerstorfi stable carbon isotope values binned by marine isotope stage from ODP Site 162-807 and ODP Site 162-982 that span the last 4.5 million years (Feng et al. 2022; Venz et al. 1999, 2002; Hodell & Venz-Curtis 2006). This isotope gradient reflects the accumulation of respired and disequilibrium carbon in the deep Pacific ocean relative to the North Atlantic. Also included are binned probstack δ18O (Ahn et al., 2017) and ΔGMST (Clark et al., 2024) values for comparison to the binned stable carbon isotope values.

本数据集包含来自大洋钻探计划（Ocean Drilling Program, ODP）162-807孔与162-982孔、覆盖过去450万年的、按海洋同位素阶段（Marine Isotope Stage, MIS）分箱处理的武氏卷转虫（Cibicides wuellerstorfi）稳定碳同位素值，数据来源包括Feng等（2022）、Venz等（1999、2002）以及Hodell与Venz-Curtis（2006）。该同位素梯度反映了相较于北大西洋，太平洋深部海洋中呼吸成因碳与非平衡碳的富集特征。本数据集同时纳入经分箱处理的概率堆叠氧同位素比值δ¹⁸O（Ahn等，2017）与全球平均地表温度距平（ΔGlobal Mean Surface Temperature, ΔGMST，Clark等，2024）数据，用于与上述分箱稳定碳同位素值开展对比分析。
