Delta 13C in CO2 at Alert, NWT, Canada (June 1991 - December 2001)

Measurements have been made on air collected in flasks at Alert, Canada, through the CSIRO GASLAB worldwide network. Flasks are filled with air at Alert and returned to the CSIRO GASLAB for analysis; typical sample storage times for flasks collected at Alert range from a few weeks to a few months. No significant effect on the stable carbon isotopic composition, δ13C, has been detected as a consequence of the sample storage time.

本数据集依托澳大利亚联邦科学与工业研究组织（Commonwealth Scientific and Industrial Research Organisation, CSIRO）GASLAB全球采样网络，对加拿大阿尔特（Alert）站点的烧瓶封存空气样本开展了测量工作。研究人员在阿尔特站点将空气充入密封烧瓶，随后将样本运回CSIRO GASLAB进行分析；阿尔特站点采集的烧瓶样本典型存储周期为数周至数月。本研究未检测到样本存储时长对稳定碳同位素组成δ¹³C存在显著影响。如需获取数据文件，请点击以下链接跳转至碳数据信息分析中心（Carbon Dioxide Information Analysis Center, CDIAC）数据转换网站：http://cdiac.ess-dive.lbl.gov/trends/co2/allison-csiro/allcsiro-alt.html
