4.5 million years of deep ocean carbon isotope gradients and trace metals redox data@en

This dataset contains a 4.5 million year record of the benthic stable carbon isotope gradient between Ocean Drilling Program Sites 982 and 807 and a long trace metals dataset from ODP Site 1208. In addition, we include compiled timeslice data from throughout the deep ocean that characterize the stable carbon isotope difference between benthic stable isotope composition of C. wuellerstorfi at Site 982 and that site.本数据集包含大洋钻探计划（Ocean Drilling Program，ODP）982站位与807站位之间的底栖稳定碳同位素梯度的450万年记录，以及来自ODP 1208站位的长时序痕量金属数据集。此外，本数据集还纳入了全球深海区域的汇编时间切片数据，用以表征982站位武勒施托夫菲卷虫（C. wuellerstorfi）的底栖稳定碳同位素组成与全球深海各站位该类有孔虫的底栖稳定碳同位素差值。
