High-resolution stable oxygen, carbon isotope and Magnesium/Calcium ratio data from ODP Site 198-1209 and 198-1210, Shatsky Rise

This dataset lists the results of stable oxygen and carbon isotope measurements (in ‰ VPDB), and trace element analysis (Mg/Ca ratios in mmol mol-1) from Ocean Drilling Program (ODP) Sites 1209 and 1210 (32°13.420'N, 158°15.5623'E, 2573 water depth, Expedition 198, Shatsky Rise). Stable isotopes were analyzed using a ThermoFinnigan MAT253Plus gas source mass spectrometer equipped with a Thermo Fisher Scientific KIEL IV carbonate device. Values are reported relative to the VPDB through the analysis of an in-house standard (Solnhofen limestone) calibrated to IAEA-603 (Heidelberg) and NBS-19 (Bremen). Mg/Ca ratios were analyzed using a Agilent Inductively Coupled Plasma-Optical Emission Spectrometer (ICP-OES) 720. Mg/Ca data was normalised relative to the ECRM752-1 standard.

本数据集收录了大洋钻探计划（Ocean Drilling Program, ODP）1209与1210站位（北纬32°13.420'，东经158°15.5623'，水深2573米，萨茨基海岭198航次）的稳定氧、碳同位素测试结果（单位为‰ VPDB）以及微量元素分析结果（Mg/Ca比值，单位为mmol mol⁻¹）。稳定同位素测试采用搭载赛默飞世尔科技（Thermo Fisher Scientific）KIEL IV碳酸盐制样装置的ThermoFinnigan MAT253Plus气相源质谱仪完成；测试值通过对经IAEA-603（海德堡）与NBS-19（不来梅）标样校准的内部标准物质（索恩霍芬石灰岩）进行分析，校准至VPDB标准并以此报告最终结果。Mg/Ca比值测试采用安捷伦（Agilent）720型电感耦合等离子体光发射光谱仪（Inductively Coupled Plasma-Optical Emission Spectrometer, ICP-OES）完成，所有Mg/Ca数据以ECRM752-1标准物质为基准进行归一化处理。
