Annual Mean Water Isotope (d18O) Record for the "DSS" Law Dome Ice Core

The LD2012-d18O-Native-age record is the annual mean water isotope (d18O) record for the "DSS" (Dome Summit South) Law Dome ice core with extensions (e.g. As described in van Ommen et al., Nature Geoscience, 2010) from overlapping ice cores which are dated by comparing multiple chemical species as well as water isotopes. LD2012-d18O-Native-age record spans 2007 A.D. to 174 A.D. The d18O measurements were completed using Isotope Ratio Mass Spectrometers.This work was done as part of AAS 757 and AAS 4061.

LD2012-d18O-原生定年记录是针对“DSS（穹顶南点Dome Summit South）”劳姆冰芯的年平均水同位素（d18O）序列，该序列通过多根重叠冰芯延伸得到（如van Ommen等人2010年发表于《自然·地球科学（Nature Geoscience）》的研究所述），其定年过程通过对比多种化学组分与水同位素特征完成。该记录的时间跨度为公元2007年至公元174年。d18O的测量工作采用同位素比率质谱仪（Isotope Ratio Mass Spectrometers）完成。本研究系AAS 757与AAS 4061项目的组成部分。
