Data from ODP Leg 145 Sites 883, 887, compiled MPWP benthic stable carbon isotopes, and example code.

Late Pliocene orbitally-tuned age models, benthic stable isotopes, composite sections, UK'37, C37 alkenone concentration, weight percent calcium carbonate, enhanced benthic foraminiferal oxygen index, and counts of benthic foraminifera, from ODP Leg 145 Site 883 and 887 from approximately 3.4 to 2.6 million years ago and compiled benthic stable carbon isotope data from the MPWP from 28 DSDP/ODP/IODP drilling sites. Also includes example code for the bootstrapping procedure used to estimate uncertainties in the stacked stable carbon isotope values.

本数据集涵盖取自大洋钻探计划（Ocean Drilling Program，ODP）第145航次883、887站位（年代跨度约3.4至260万年前）的轨道调谐年龄模型（orbitally-tuned age models）、底栖稳定同位素（benthic stable isotopes）、复合剖面（composite sections）、UK'37、C37烯酮浓度（C37 alkenone concentration）、碳酸钙重量百分比（weight percent calcium carbonate）、增强型底栖有孔虫氧指数（enhanced benthic foraminiferal oxygen index）以及底栖有孔虫计数（counts of benthic foraminifera）；同时整合了来自MPWP的28个DSDP/ODP/IODP钻探站位的底栖稳定碳同位素数据，并附带用于估算堆叠稳定碳同位素值不确定性的自助法（bootstrapping procedure）示例代码。
