Methane Measurements from the GISP2 and Siple Dome Ice Cores

Abstract: This data set contains methane measurements made in trapped air in the Holocene sections of two ice cores: the Siple Dome ice core in Antarctica, and the Greenland Ice Sheet Project 2 (GISP2) ice core in Greenland. The measurements were made at Oregon State University between 2007 and 2009. Measurements were made relative to the NOAA04 methane concentration scale using a working standard internally calibrated to NOAA certified air standards. Concentrations are corrected for gravitational fractionation and solubility effects in the melt-refreeze extraction. Data are available via FTP in Microsoft Excel (.xls) format.

摘要：本数据集包含两支冰芯全新世剖面捕获空气中的甲烷测量数据：分别为南极Siple Dome冰芯，以及格陵兰冰盖项目2（GISP2）冰芯。该测量工作于2007至2009年间在俄勒冈州立大学完成，测量以NOAA04甲烷浓度标尺为基准，使用了经内部校准至美国国家海洋和大气管理局（NOAA）认证空气标准的工作标准品。浓度值已针对融冻萃取过程中的重力分馏与溶解度效应完成校正。数据可通过FTP以Microsoft Excel（.xls）格式获取。
