Stable oxygen and carbon isotope data of Cibicidoides wuellerstorfi at DSDP Site 72-516, Rio Grande Rise

This dataset includes the analysis of sediment core DSDP 516 (30°16'S, 35°17'W, 1313 m water depth) recovered from the Rio Grande Rise within the modern day core of Antarctic Intermediate Water (AAIW). It contains benthic foraminiferal stable oxygen and carbon isotopes measured on Cibicidoides wuellerstorfi from the >250μm fraction of DSDP 516 covering the last 600,000 years. The dataset also includes measured reference material Carrara Marble. Measurements were made on a ThermoScientific MAT 253 mass spectrometer coupled with a KIEL IV Carbonate precipitation device.

该数据集包含对DSDP 516岩芯的分析结果，该岩芯位于南纬30°16'、西经35°17'，水深1313米，取自现代南极中层水（Antarctic Intermediate Water，AAIW）核心区域内的里奥格兰德海隆。数据集中涵盖了过去60万年间，DSDP 516岩芯中粒径大于250μm的伍氏瓶虫（Cibicidoides wuellerstorfi）底栖有孔虫的稳定氧同位素与碳同位素测量值。此外，数据集还包含卡拉拉大理石（Carrara Marble）参考物质的测量数据。所有测量均通过ThermoScientific MAT 253质谱仪耦合KIEL IV碳酸盐沉淀装置完成。
