Clumped isotopic composition of oxygen in WDC06A ice core 8-18ka@en
收藏资源简介：
Laboratory O2 clumped-isotopic composition data (as Δ36 values) for air occluded in ice core spanning gas ages of 8000-18000 ky BP. O2 clumped isotopic composition data was generated between 2017-2022 at Rice University, Houston, TX, using a Nu Perspective Isotope Ratio Mass Spectrometer (IRMS). Reported data was measured in an Antarctic ice core: West Antarctic Ice Sheet Divide Ice Core (WDC06A) . The chronology and gas ages for the core were obtained from Sigl et al., 2016 (doi:10.5194/cp-12-769-2016) and Buizert et al., 2015 (doi:10.5194/cp-11-153-2015). […]
本数据集为冰芯包裹空气的氧气团簇同位素组成数据（以Δ36值表征），其气体年代覆盖距今8000至18000千年。本次氧气团簇同位素组成数据的测定工作于2017至2022年间在美国德克萨斯州休斯顿莱斯大学完成，所用仪器为Nu Perspective型同位素比率质谱仪（Isotope Ratio Mass Spectrometer，IRMS）。本次报道的实验数据采自南极冰芯——西南极冰盖分水岭冰芯（West Antarctic Ice Sheet Divide Ice Core，WDC06A）。该冰芯的年代学框架与气体年代数据引自Sigl等人2016年的研究（doi:10.5194/cp-12-769-2016）以及Buizert等人2015年的研究（doi:10.5194/cp-11-153-2015）。[…]
